EMBODIMENT FOR CARRYING OUT THE INVENTION

[0051] The following section will describe an embodiment to carry out the present invention with reference to the drawings. The following description schematically shows a scope required for the description to achieve the objective of the present invention and will mainly describe the scope of the present invention and will not describe known techniques.

[0052] FIG. 1 is a perspective conceptual diagram illustrating the entirety of a medical device-fixing system according to one embodiment of the present invention. As shown in FIG. 1, a medical device-fixing system 1 according to one embodiment of the present invention is configured to include a pillar-like support member 11, a hook section 12, a holder 13, and a medical device 14. The holder 13 is connected to a lock section 15 having a push button 16. The hook section 12 has a concave groove section 17 to which the lock section 15 of the holder 13 is inserted and locked.

[0053] As shown in FIG. 1, the hook section 12 is fixed by being engaged and tightened to the outer periphery of the pillar-like support member 11. The pillar-like support member 11 also may be a drip infusion pillar or a wheelchair configuration pillar or a bed pillar or a pillar-like support member as a general movable member. The pillar-like support member 11 in FIG. 1 shows a drip infusion pillar (also may referred to as a portable drip infusion pole or a drip infusion wagon).

[0054] The human body connection-type medical device 14 is fixed and held while allowing the outer periphery of the back face to be covered by the holder 13. The medical device 14 is a medical device connected to a human body such as a chest drainage unit or a syringe pump or an infusion pump or a biological observation measurement device (e.g., sphygmomanometer, electrocardiogram). In FIG. 1, the medical device represents the chest drainage unit. The medical device 14 is fixed and held by the holder 13. Thus, when the medical device 1 is not fixed or locked to the hook section 12, the medical device 14 and the holder 13 are potable in an integrated manner. The medical device 14 has a grip section 18 that is gripped for transportation. The grip section 18 also may be attached to the holder 13.

[0055] As shown in FIG. 1, the holder 13 has, at an upper part at substantially the center, the lock section 15 that can be cancelled by the push button 16. The lock section 15 is inserted to the concave groove section 17 provided at the upper part at the holder 13 side of the hook section 12 to lock and fix the lock section 15. In FIG. 1, the lock section 15 of the holder 13 is inserted and set in a lock state. Thus, the concave groove section 17 of the hook section 12 is not shown.

[0056] The lock section 15 that can be cancelled by the push button 16 also may be based on a slide button cancellation method or an axial rotation cancellation method or an electrical switch cancellation method or an electromagnetic cancellation method or a fingerprint authentication cancellation method or a password cancellation method, as has been described above. These respective lock methods and cancellation methods have been used in the prior art and may be appropriately selected. When the slide button cancellation method is used for example, it is desired that the slide button is provided in the vicinity of a handle section 18 so that the slide button can be slid by a thumb of one hand gripping the handle. Specifically, the cancellation is achieved by the two actions by one hand.

[0057] FIG. 2 is a perspective conceptual diagram illustrating the hook section of the medical device-fixing system according to one embodiment of the present invention. As shown in FIG. 2, the medical device-fixing system according to one embodiment of the present invention has the hook section 12 having a hollow cylindrical structure corresponding to the diameter of the pillar-like support member 11 sandwiched by the hook section 12. This hollow cylindrical structure is divided to a hook A section 20 and a hook B section 21 that are engaged with the pillar-like support member 11 for fixation.

[0058] In FIG. 2, a screw 19 is used to allow the hook A section 20 and the hook B section 21 to sandwich the pillar-like support member 11 for engagement and fixation. However, neither the pillar-like support member 11 nor the hook section 12 is limited to a circular column-like or cylindrical shape. Any structure may be used so long as the structure allows the hook section 12 to be engaged with and fixed to the pillar-like support member 11 in a secure manner. In addition to the fixation by a screw, various fixing methods according to the conventional method may be used.

[0059] As shown in FIG. 2, the hook B section 21 side of the hook section 12 has a lock section receiving section 22 whose upper face has a concave groove section 7 having a cylindrical shape for example. The concave groove section 7 has a structure to which the lock section 15 of the holder 13 described above is inserted. As shown in FIG. 2, the lock section receiving section 22 may have a pin 23 at the outer periphery thereof. The pin 23 may be engaged and positioned in a slit formed in the lock section 15 of the holder 13 to thereby prevent the holder 13 from freely rotating.

[0060] In FIG. 2, the concave groove section 7 of the hook section 12 receives the lock section 15 of the holder 13. However, this is one example. Thus, the medical device-fixing system according to the present invention is not limited to a method to lock and engage the hook section and the holder using the insertion to the cylindrical body as shown in FIG. 2. The hook section and the holder may be locked and engaged based on various methods of the prior art. The technical concept of the present invention includes such similar techniques.

[0061] FIG. 3 is a perspective conceptual diagram of the holder of the medical device-fixing system according to one embodiment of the present invention. As shown in FIG. 3, the medical device-fixing system according to one embodiment of the present invention has the holder 13 that is a so-called fixing jig to cover and fix the medical device 14 at the outer periphery circumference. The holder 13 is composed of a holder main body 24, a holder bottom section 25, the lock section 15, and a rotation shoulder section 26. As described above, when the lock state of the lock section 15 is cancelled using a push button, the push button 16 is preferably used as shown in FIG. 3.

[0062] As shown in FIG. 3, the holder main body 24 of the holder 13 is configured to function together with the holder bottom section 25 to cover the outer periphery or the bottom face of the medical device depending on the shape of the medical device 14 to securely fix the medical device. The holder main body 24 of the holder 13 is preferably detached in an easy manner. The present invention is not limited to the material of the holder 13. The holder 13 is preferably a sheet metal member for example because the formability and fixation are good.

[0063] The medical devices include a medical device attached and connected to a human body such as a chest drainage unit or a syringe pump or an infusion pump or a biological observation measurement device (e.g., sphygmomanometer, electrocardiogram). The holder 13 may have a shape appropriate for to fix the outer periphery of each medical device. Thus, the present invention is not limited to the holder shape as shown in FIG. 3.

[0064] As shown in FIG. 3, the holder 13 may have the rotation shoulder section 26 for example. The long bar-like rotation shoulder section 26 is provided for the purpose of fixing the outer periphery of the medical device 14 in a secure manner. For example, the rotation shoulder section 26 is configured so that one end has a rotation center section 27 around which the rotation shoulder section 26 is rotated and the other end has a latch section 28 engaged with the upper end of the outer periphery of the medical device 14 to thereby allow the rotation shoulder section 26 and the holder bottom section 25 to sandwich the medical device 14 in the up-and-down direction, thereby providing a secure fixing.

[0065] As described above, the rotation shoulder section 26 and the holder bottom section 25 sandwich the medical device 14 in the up-and-down direction. Since the rotation shoulder section 26 has a main purpose of providing a secure fixing, the direction along which the medical device 14 is fixed by the rotation shoulder section of the medical device-fixing system according to the present invention is not always limited to the up-and-down direction and also may be a lateral left-and-right direction or a front-and-rear direction. Specifically, depending on the outer shape of the medical device to be fixed and secured, the rotation shoulder section may have various different lengths, sizes, or rotation directions for example. Thus, the holder 13 also may have various shapes such as different lengths, sizes, or rotation directions for example depending on the outer shape of the medical device. The technical concept of the present invention includes such similar techniques.

[0066] FIG. 4 is a perspective conceptual diagram illustrating the lock section of the holder of the medical device-fixing system according to one embodiment of the present invention. As shown in FIG. 4, the lock section of the holder of the medical device-fixing system according to one embodiment of the present invention is composed of the push button 16, a lock section outer shape section 29, and a holder connection section 30. The internal structure thereof will be described later.

[0067] As shown in FIG. 4, the lock section outer shape section 29 of the lock section 15 has a cylindrical structure for example in which the inner periphery receives the lock section receiving section 22 of the hook section 12 inserted from the lower side. The lock section outer shape section 29 has, at the holder 13 side, the holder connection section 30 connected and fixed to the holder 13. The holder connection section 30 is a part that is securely connected and fixed to the upper part of the holder main body 24 at substantially the center. The holder connection section 30 also may not be connected or fixed to the upper part of the holder main body 24 at substantially the center in view of the weight and centroid of the medical device. The slit 31 can be engaged with the pin 23 of the hook section 12 described above and is positioned and fixed to thereby prevent the holder 13 from freely rotating.

[0068] FIG. 5 is a cross-sectional conceptual diagram illustrating how the lock section and the concave groove section of the medical device-fixing system according to one embodiment of the present invention are locked. As shown in FIG. 5, the lock section 15 is mainly composed of an inner cylinder section 39, the lock section outer shape section 29, a spring 32, a rotation tab section 33, and the holder connection section 30. The hook section 12 is composed of the lock section receiving section 22 and the concave groove section 17.

[0069] In FIG. 5, the lock section 15 and the hook section 12 both have a cylindrical shape and are mutually engaged and fixed. However, the present invention is not limited to such a cylindrical shape for the engagement. Thus, various other shapes also may be used according to the prior art.

[0070] In addition to the above, FIG. 5 illustrates a state immediately before the lock section and the concave groove section are engaged and locked in the medical device-fixing system according to one embodiment of the present invention. The push button 16 of the lock section 15 is movable in the up-and-down direction along the inner diameter of the inner cylinder section 39 via the spring 32. The inner cylinder section 39 is integrated with the lock section outer shape section 29 and the holder connection section 30. The lower part of the push button 16 is linked to the rotation tab section 33 via the spring 34.

[0071] As shown in FIG. 5, the rotation tab section 33 is rotated around a rotation center axis 35 and has a tab 34 that is abutted to the lowermost part of the push button 16 and is abutted to the inclined section 38 along the inner diameter of the concave groove section 17 of the hook section 12. The slit 31 of the lock section 15 is configured in a direction along which the slit 31 is engaged with the pin 23 of the hook 12 for a positioning purpose.

[0072] FIG. 5 illustrates a state immediately before the lock section and the concave groove section are engaged and locked in the medical device-fixing system according to one embodiment of the present invention. In an order of FIG. 5, FIG. 6, and FIG. 7, the process will be described in which the lock section 15 is inserted to the concave groove section 17 of the hook 12 and is engaged, locked, and fixed after which the engagement and locking are cancelled.

[0073] FIG. 6 is a cross-sectional conceptual diagram illustrating how the lock section and the concave groove section are locked in the medical device-fixing system according to one embodiment of the present invention. FIG. 6 illustrates a state in which the lock section 15 is inserted to the concave groove section 17 of the hook section 12 and is engaged, locked, and fixed. When the lock section 15 is inserted to the concave groove section 17 of the hook section 12, the lock section receiving section 22 of the hook section 12 having a cylindrical shape is inserted to a gap between the lock section outer shape section 29 of the lock section 15 having a cylindrical shape larger than the lock section receiving section 22 of the hook section 12 and an inner cylinder body 39 having a cylindrical shape smaller than the lock section receiving section 22 of the hook section 12.

[0074] During this insertion, the tab 34 of the rotation tab section 33 of the lock section 15 is downwardly moved along the concave groove section 17 of the inner wall of the lock section receiving section 22 of the hook section 12. On the other hand, an inner wall groove section 40 is formed in the vicinity of the inlet of the inner wall of the lock section receiving section 22 of the hook section 12. Thus, the tab 34 of the rotation tab section 33 of the lock section 15 is inserted to the inner wall groove section 40 and is latched to a tab receiving section 36. In this manner, the lock section is securely engaged with and locked to the concave groove section of the hook section 12 in the medical device-fixing system according to one embodiment of the present invention.

[0075] Specifically, according to the medical device-fixing system according to one embodiment of the present invention, the lock section 15 to which the medical device is fixed and engaged and the hook section 12 fixed to the pillar are engaged and fixed by one touch operation to insert the lock section to the hook section, thereby providing a secure locking. In this state, it is completely impossible to upwardly draw the holder 13 and the lock section 15, thus providing a secure and safe locked state.

[0076] As described above, according to the present invention, the human body connection-type medical device is connected and fixed to the movable drip infusion pillar for example in a safe and secure manner. The medical device is prevented from being easily detached or fallen from the pillar. The human body connection-type medical device can be safely moved together with the person connected thereto. The pillar-like support member 11 also may be a wheelchair pillar and can be moved safely together with the wheelchair. Alternatively, the pillar-like support member 11 may be a pillar attached to the bed to allow the patient to move together with the bed while the medical device being attached thereto.

[0077] FIG. 7 is a cross-sectional conceptual diagram illustrating how the lock section and the concave groove section are locked in the medical device-fixing system according to one embodiment of the present invention. As shown in FIG. 7, the next step is to cancel the engagement and locking between the lock section 15 and the concave groove section 17 of the hook section 12 by the push button 16.

[0078] As shown in FIG. 7, the push button 16 is depressed to cancel the secure engagement and locking between the lock section 15 and the hook section 12. Simultaneously with the downward depression of the spring 32 by the push button 16 along the inner wall of the inner cylinder section 39, a push button convex section 37 of the lowermost part of the push button 16 depresses the inclined section 38 of the rotation tab section 33 in the inclination direction. Then, the rotation tab section 33 is rotated to the right around the rotation center axis 35 (in the case of FIG. 7). Then, the tab 34 of the rotation tab section 33 is detached from the inner wall groove section 40 and the tab receiving section 36 of the concave groove section 17 of the hook section 12 to thereby cancel the engagement, locking and fixing state. Thereafter, the holder 13 and the medical device are upwardly drawn from the hook section 12 of the pillar and are separated from the secure engagement and connection.

[0079] As described above, the internal mechanism has been described for the medical device-fixing system according to one embodiment of the present invention to insert, engage, lock and fix the lock section to the concave groove section to subsequently cancel the engagement and locking state. However, this internal mechanism to insert, engage, lock and fix the lock section to the concave groove section to subsequently cancel the engagement and locking state is an example and does not limit the invention. Various engagement and locking mechanisms for the same purpose may be considered in the prior art and are included in the concept of the present invention.

[0080] In addition, the technical concept of the present invention in the medical device-fixing system according to one embodiment of the present invention is based not only on the above structure of the engagement and locking mechanism but also on a mechanism in which the medical device is fixed to another drip infusion pillar for example by being easily inserted but is prevented, once locked, from being detached due to the cancellation. Furthermore, the medical device can be detached from the drip infusion pillar for example by cancelling the locked state by one hand. However, a direction along which the medical device holder and the holder are drawn and detached is opposite to a direction along which the push button is depressed by a finger to cancel the locked state. Thus, the invention is based on the technical concept providing the highest safety achieved by the operation composed of the two actions (2-step operation). Thus, the invention suggests a system to completely avoid a careless lock cancellation.

[0081] This is a specific example of a safety-first system to connect and fix the human body medical device to the movement pillar as a main objective of the present invention described above. Specifically, the user is allowed to grip the handle of the frame for fixing the chest drainage unit body to suspend the handle on the hook of the pillar as a moving body to thereby connect and lock the handle on the hook. This connection is securely maintained in the fixed state unless any unlock operation is achieved.

[0082] In order to unlock the locked state, the user is allowed to grip the handle section of the frame for fixing the chest drainage unit body while depressing the push button by the thumb of the hand for example to perform the two-stage unlocking operation (two actions), thereby unlocking the chest drainage unit body from the drip infusion pillar. The two actions are performed by the hand or the arm moved in different directions. Thus, the locked state cannot be easily cancelled without the intended cancellation operation, thus avoiding a risk and providing a completely-safe apparatus system. This lock cancellation cannot be achieved without the simultaneous execution of the operations in different directions. Thus, no unintended cancellation is caused, thus providing an effective means to prevent a falling accident.

[0083] The present invention is not limited to the above-described embodiments. The present invention can be subjected to various modifications within the scope without deviating from the scope of the invention. Such modified embodiments are all included in the technical concept of the present invention. The equivalent methods using the prior art are also included in the technical concept of the present invention.

INDUSTRIAL APPLICABILITY

[0084] As described above, according to the invention of this application, a connection system to connect the patient and the human body connection-type medical device can be developed and provided that allows the human body of the patient to be continuously attached and connected to various medical devices (e.g., a chest drainage unit or a syringe pump or an infusion pump or a biological observation measurement device (e.g., sphygmomanometer, electrocardiogram)) while allowing the patient to simply move or walk. This system is safe and can completely secure the function of the medical device.

[0085] Specifically, according to the invention of this application, such a medical device-fixing system is realized by which the patient can move with the human body connection-type medical device in an integrated manner with remarkably-improved safety usability while providing a dramatically-improved economic efficiency.

[0086] Thus, the present invention is not limited to a medical setting such as a hospital and can be applied to any medical-related facilities. Thus, this application is useful in various industries including the medical field.
