(23) Several technologically representative examples of the invention are recited below. In order to simplify the disclosure of the invention, in each of the recited examples, the same or like elements are illustrated with the same symbol and the same or like illustrations are done in simplified modes.

FIRST EXAMPLE

(24) Refer to FIG. 1 to FIG. 5, in which a schematic diagram for a first example of the hemostatic equipment of the invention is shown. As shown in FIG. 1, the hemostatic equipment 1 of the invention is composed of at least a pallet 11 and an inflatable pillar 12. The pallet 11 has a carrier 111 and a holder 112, wherein the carrier 111 and the holder 112 may be made of plastic material. A patient may hold the pallet 11 by the holder 112, while a force is applied for the holder 112 to move the carrier 111 toward to a nostril of a patient. In the example, the holder 112 extends downwards from one end of the carrier 111 to define a finger-through space below the carrier 111. The finger-through space is for the patient to operate the holder 112 through fingers.

(25) In the example, the holder 112 is intersected with the carrier 111 vertically, but not limited thereto. Intersection angle of the holder 112 and the carrier 111 may also be changed for a patient to operate the holder 112 easily, and even more, the holder 112 and carrier 111 may be set in one plane.

(26) The inflatable pillar 12 may be made of porous foaming material. In forming, the inflatable pillar 12 may be compressed to shrink volume in order to enter the nasal cavity of a patient smoothly, and the inflatable pillar 12 may be inflated to press bleeding inside a nasal cavity of a patient to stop bleeding after absorbing liquid. The inflatable pillar 12 may be made of a material with good liquid absorption and inflation capabilities. Preferably, the inflatable pillar 12 may be made of foam material containing polyvinyl alcohol (PVA). Additionally, the inflatable pillar 12 shown in FIG. 1 has a rectangular section, but shape of a section for the inflatable pillar 12 may also be changed to circle, ellipse, triangle or a combination of various shapes under different use circumstances.

(27) The inflatable pillar 12 may be divided into two parts, a head 121 and a body 122. The head 121 is exposed with a pressing surface used to press a bleeding site inside a nasal cavity of a patient for hemostasis. Tail end of the body 122 is implanted on the carrier 111 away from the holder 112. Preferably, the carrier 111 may have multiple walls 1114 to define an implantation area used for implanting tail end of the body 122 of the inflatable pillar 12, beneficial to implantation of the inflatable pillar 12. Moreover, each of the walls 1114 may support tail end of the body 122 of the inflatable pillar 12 laterally to assure the inflatable pillar 12 on the carrier 111.

(28) For the inflatable pillar 12 with respect to the compression rate in forming, the head 121 is larger than the body 122 such that the head 121 may enter a nasal cavity of a patient through a nasal meatus of a patient smoothly before inflation of the inflatable pillar 12. As shown in FIG. 1, lateral figure of the inflatable pillar 12 is approximate to a 1 shape before inflation of the inflatable pillar 12, that is the section size of the head 121 is close to that of the body 122, such that the head 121 may enter the nasal cavity of the patient smoothly before inflation of the inflatable pillar 12.

(29) As the inflatable pillar 12 absorbs blood, the inflatable pillar 12 is in inflation, and the volume of the head 121 is larger than that of the body 122, such that the pressing surface of the head 121 may move until pressing a bleeding site inside of a nasal cavity of a patient. As shown in FIG. 4, the inflatable pillar 12 is in inflation, wherein section size of the head 121 is larger than that of the body 122 apparently, and the head 121 is inflated in a specific direction. In such state, lateral figure of the inflatable pillar 12 is approximate to inverted L shape, or approximate to T shape such that the head 121 is available to press a bleeding site inside of a nasal cavity of a patient, and may be engaged inside a nasal cavity of a patient for pressing continuously. In addition, the inflatable pillar may utilize the head engaged inside a nasal cavity of a patient to avoid easy detachment from a nostril of a patient during use to provide continuous hemostatic function.

(30) The inflatable pillar 12 may be implanted onto the carrier 111 in at least one mode of sticking, locking and engagement, but not limited thereto. Other modes are available, such as direct combination with the inflatable pillar 12 during injection molding of the carrier 111 to achieve implantation of the inflatable pillar 12 onto the carrier 111. The inflatable pillar 12 may be filled with a medicine for treating bleeding inside a nasal cavity of a patient such that the medicine is released from the inflatable pillar 12 after the inflatable pillar 12 enters the nasal cavity to accelerate treatment of intranasal bleeding symptom.

(31) The operation for the hemostatic equipment of the invention is directionality. As shown in FIG. 2, the hemostatic equipment 1 is operated in a correct direction (i.e., the direction for the pressing surface of the head 121 is correct so that a bleeding site inside of a nasal cavity of a patient can be pressed by the pressing surface after inflation of the head 121). In such operation state, partial fingers of the patient for operation of the hemostatic equipment 1 may be stuck into the finger-through space below the carrier 111, and may abut outer wall of the holder 112 in conjunction with other fingers, respectively, in order to apply a force to the holder 112 to move the inflatable pillar 12 into the nasal cavity of the patient until the pressing surface of the head 121 of the inflatable pillar 12 is in alignment with a bleeding site inside a nasal cavity of a patient. Subsequently, as shown in FIG. 5, the inflatable pillar 12 entering the nasal cavity would get inflated after liquid absorption, such that the pressing surface of the head 121 is forced to press a bleeding site inside a nasal cavity of a patient for hemostasis.

(32) As shown in FIG. 3, the hemostatic equipment 1 is operated in a wrong direction (i.e., the direction for the pressing surface of the head 121 is wrong, such that a bleeding site inside a nasal cavity of a patient cannot be pressed after inflation of the head 121). In such a state, in the process forcing movement of the inflatable pillar 12 with fingers of the patient that abut the holder 112, the fingers would touch a face of a patient and the inflatable pillar 12 is blocked from sticking into the nasal cavity of the patient. That is, the holder 112 may provide foolproof effect in operation direction to ensure that the pressing surface of the head 121 of the inflatable pillar 12 can enter a nasal cavity of a patient in a correct direction.

(33) Therefore, the operation of the hemostatic equipment of the invention is directionality. As long as a patient operates the hemostatic equipment in a correct direction, the pressing surface of the head of the inflatable pillar may be in alignment with a bleeding site inside a nasal cavity of a patient, so that a patient can operate the hemostatic equipment of the invention by oneself without assistance from professional medical staff, suitable for home medical care. That is, the hemostatic equipment of the invention may provide foolproof effect in an operation direction, and ease to use at home without assistance from professional medical staff.

(34) The hemostatic equipment disclosed in the example comprises two inflatable pillars 12 which are arranged separately on the carrier 111. The two inflatable pillars 12 can enter left and right nostrils of a patient, respectively. Distance between the two inflatable pillars 12 is defined by thickness of a nasal septum of a patient, such that the two inflatable pillars 12 can keep away from a nasal septum of a patient in use.

(35) Additionally, in the example, the pallet 11 has a reinforcement body 113, which is arranged at intersection of the carrier 111 and the holder 112 to ensure that the carrier 111 and the holder 112 can keep combination under force application in operation, that is, the carrier 111 and the holder 112 would not separate due to force application easily in using the pallet 11.

SECOND EXAMPLE

(36) Refer to FIG. 6 showing a schematic diagram of a second example for the hemostatic equipment of the invention. The largest difference between the example and the above example is that: one end of the carrier 111 arranged with the inflatable pillar 12 has a disconnection slot 1111 extended from an outer edge inwards to define a left cantilever 1112 and a right cantilever 1113, which may be forced to deform, respectively, on the carrier 111. As shown in FIG. 6, the two inflatable pillars 12 are arranged on the left cantilever 1112 and the right cantilever 1113, respectively. The two inflatable pillars 12 can be moved by deformation of the left cantilever 1112 and the right cantilever 1113 to help to entering in a nasal cavity of a patient. The carrier 111 may be formed with a bore 11111 additionally for an apex nasi of a patient to enter when the hemostatic equipment 1 is in use, in order to prevent protruded portion of an apex nasi of a patient to abut the carrier 111, such that the head 121 of the inflatable pillar 12 can go deep into the nasal cavity of the patient. Preferably, the bore 11111 is formed on tail end of the disconnection slot 1111.

(37) Additionally, in the hemostatic equipment of the example, the pallet 11 has a weakness 114 formed of structural weakness. A patient can separate the left cantilever 1112 and the right cantilever 1113 by fracturing the weakness 114, so that hemostasis for stopping bleeding inside a nasal cavity of a patient is available by using the inflatable pillar 12 of either the left cantilever 1112 or the right cantilever 1113.

THIRD EXAMPLE

(38) Refer to FIGS. 7 to 9 showing schematic diagrams of the third example for the hemostatic equipment of the invention. The largest difference between the example and the above example is that: only one inflatable pillar 12 is arranged on the carrier 111 for hemostasis of a nostril of a patient in bleeding. Therefore, the number of the inflatable pillars arranged on the hemostatic equipment of the invention is not limited to two.

(39) For applicability to users of various somatotypes, the size ranges of various lengths for the states of the inflatable pillar of the hemostatic equipment of the invention before and after inflation are illustrated as following: As shown in FIG. 8, the inflatable pillar 12 of the invention is in a state before inflation, wherein the length size indicated by symbol a is between 2.5 mm and 20 mm; the length size indicated by symbol b is between 1.5 mm and 15 mm. In addition, as shown in FIG. 9, the inflatable pillar 12 of the invention is in a state after inflation, wherein the length size indicated by symbol A is between 5 mm and 30 mm; the length size indicated by symbol B is between 3 mm and 22 mm; the length size indicated by symbol C is between 3 mm and 22 mm; the length size indicated by symbol D is between 1.5 mm and 7 mm; the length size indicated by symbol E is between 2 mm and 12 mm.

FOURTH EXAMPLE

(40) Refer to FIGS. 10 to 15 showing schematic diagrams of the fourth example for the hemostatic equipment of the invention. As shown in FIG. 10, an implantation area of the wall 1114 is formed on the pallet 11. As shown in FIG. 11, the inflatable pillar 12 can enter a nasal cavity of a patient before inflation smoothly. As shown in FIG. 12, the inflatable pillar 12 can press a bleeding site inside a nasal cavity of a patient to stop bleeding inside a nasal cavity of a patient after inflation.

(41) The distance size between the left and right boundaries L, R of the implantation area is larger than the width size of the inflatable pillar 12, such that the location at which the inflatable pillar 12 be implanted onto the pallet 11 is not unique. As shown in FIG. 13, the implantation locations of the two inflatable pillars 12 on the pallet 11 are adjacent to the left and right boundaries L, R of the square-like implantation area, respectively. In such state, the center distance size length of the two inflatable pillars 12 is represented as symbol D1. As shown in FIG. 14, the implantation locations of the two inflatable pillars 12 on the pallet 11 are adjacent to the right and left boundaries R, L of the square-like implantation area, respectively. In such state, the center distance size length of the two inflatable pillars 12 is represented as symbol D2. As shown in FIG. 15, the implantation locations of the two inflatable pillars 12 on the pallet 11 are both adjacent to the right boundary R of the square-like implantation area. In such state, the center distance size length of the two inflatable pillars 12 is represented as symbol D3. Form what disclosed in FIGS. 13 to 15, the length represented as symbol D1 is larger than that represented as symbol D3, which is larger than the length represented as symbol D2. Therefore, the length of the center distance for the two inflatable pillars 12 in the example may be adjusted in adaptation to distance between two nostrils of a patient for applicability to patients with various somatotypes.

(42) Additionally, in the example, the inflatable pillar 12 comprises a through-hole 123, which has openings on the head 121 and the body 122, respectively. Preferably, the through-hole 123 extends from the top surface of the head 121 to the bottom surface of the body 122. Correspondingly, the location of the carrier 111 facing the through-hole 123 is formed with a hole in communication with the through-hole 123. As such, the through-hole 123 of the inflatable pillar 12 and the hole of the carrier 111 may act as the channel for respiration of a patient, and may also act as channel for a medical staff to fill medicine in the inflatable pillar 12.

(43) The hemostatic equipment 1 is provided with a test strip 124, which may contact the inflatable pillar 12 for testing the state of the inflatable pillar 12 through, for example, color change in order for a patient to handle the use state of the inflatable pillar 12. For example, the test strip 124 may be used to test the liquid absorption state of the inflatable pillar 12. More particularly, the test strip 124 may further test the composition of the liquid absorbed by the inflatable pillar 12 in order for medical care judgment.

FIFTH EXAMPLE

(44) Refer to FIGS. 16 to 18 showing schematic diagrams of the fifth example for the hemostatic equipment of the invention. As shown in FIG. 17, the location of the carrier 111 of the pallet 11 in the example for implanting the inflatable pillar 12 is provided concavely with a fixation pit 1115 in advance to replace the wall disclosed in the examples above. The fixation pit 1115 may be filled with adhesive for sticking and fixing the tail end of the body 122 of the inflatable pillar 12 entering the fixation pit 1115 to achieve implantation of the inflatable pillar 12 onto the carrier 111. In addition to the adhesive, other fixation mechanisms for the fixation pit 1115 may also be selected to fix the inflatable pillar 12 entering the fixation pit 1115.

SIXTH EXAMPLE

(45) Refer to FIG. 19 showing schematic diagrams of the sixth example for the hemostatic equipment of the invention. As shown in FIG. 19, the location of the carrier 111 of the pallet 11 in the example for implanting the inflatable pillar 12 is provided concavely with a fixation pit 1115 in advance to replace the wall disclosed in the examples above.

(46) In summary, the hemostatic equipment of the invention comprises an inflatable pillar and a pallet. The head of the inflatable pillar is exposed with a pressing surface. The holder of the pallet is used for a patient to hold, while the applied force moves the carrier of the pallet toward to a nostril of a patient. Moreover, there is provided with foolproof effect for operation to ensure that the pressing surface of the head of the inflatable pillar may be in alignment with a bleeding site after entering a nasal cavity of a patient in order to stop bleeding inside a nasal cavity of a patient. As such, a patient can operate the hemostatic equipment by oneself without assistance from professional medical staff so that it is applicable to home use.

(47) The examples above are only illustrative to explain principles and effects of the invention, but not to limit the invention.
