First Embodiment
[0069] As illustrated in
[0070] In particular, the top part 10, the bottom part 20, and the safety part 30 may be formed of a synthetic resin. Particularly, the top part 10, the bottom part 20, and the safety part 30 may be formed of, but is not limited to, polyvinyl chloride (PVC), polyethylene (PE), or polypropylene (PP).
[0071] The PVC is advantageous in terms of non-toxicity, as well as superior weather resistant and chemical stability.
[0072] The PE is advantageous in terms of not being discolored even when exposed to the sunlight, being a relatively stable material, and having high thermal resistance and durability.
[0073] The PP is advantageous in terms of having superior transparency, tensile strength, thermal resistance, chemical resistance compared to the PE and being non-harmful to the human.
[0074] The needle member 50 may be formed of plastic or metal.
[0075] When the needle member 50 is formed of a plastic, the needle member 50 is elastic and flexible. Thus, there is an advantage in that, in the case of the injection of a Ringer solution, the needle member 50 is not released from the blood vessel even when a patient moves.
[0076] In addition, when the needle member 50 is formed of a metal, the needle member 50 may be particularly formed of a stainless steel. Advantageously, the stainless steel does not contain a heavy metal or does not produce a toxic substance, and has superior durability and thermal resistance.
[0077] The elastic member 40 is formed of a metal, and may be formed of the same material as the needle member 50.
[0078] First, as illustrated in
[0079] In addition, a thread (not shown) is provided on the inner portion of the other end of the first housing 110. When the disposable safety syringe needle 1 is coupled to the syringe device 2, the disposable safety syringe needle 1 is not released from the syringe device 2.
[0080] In particular, since the thread is provided on the inner portion of the other end of the first housing 110, the disposable safety syringe needle 1 is tightly coupled to the syringe device 2. Thus, a seal is provided between the disposable safety syringe needle 1 and the syringe device 2, thereby advantageously preventing a contained medicine from leaking.
[0081] As illustrated in
[0082] As illustrated in
[0083] In addition, particularly, the diameter of the first support portion 140 may be set to be the same as the inner diameter of the elastic member 40. Thus, the elastic member 40 is prevented from being released from the first support portion 140 due to the tension and compression force of the elastic member 40, thereby minimizing the defective rate of the disposable safety syringe needle 1.
[0084] In particular, since the elastic member 40 is fixed to the first support portion 140, the tension and compression force of the elastic member 40 are directly transferred to the safety part 30, thereby making it impossible to reuse the disposable safety syringe needle 1 after use thereof. Advantageously, a third person is prevented from being infected by the used needle member.
[0085] As illustrated in
[0086] Here, as illustrated in
[0087] In addition, a first hole 160 and a second hole 180 are formed in one end and the other end of the second support portion 150, respectively, as holes through which the needle member 50 is introduced.
[0088] In addition, as illustrated in
[0089] When the inner diameter of the first hole 160 is set to be smaller than or the same as the outer diameter of the needle member 50, the tip portion of the needle member 50 may be blunted during the introduction of the needle member 50 into the second support portion 150, so that the function of the needle member 50 as a needle may be lost.
[0090] In addition, when the inner diameter of the second hole 180 is greater than the outer diameter of the needle member 50, the needle member 50 may not be fixed to the second support portion 150, thereby causing a medical accident.
[0091] That is, the needle member 50 is fixed after being introduced in the direction from the first hole 160 to the second hole 180 in order to prevent a medical accident while not losing the function as a needle.
[0092] The first housing 110 includes a first guide 120 and first guide protrusions 121 on outer peripheral portions of the first housing 110 to prevent the disposable safety syringe needle 1 from slipping while being coupled to the syringe device 2.
[0093] As illustrated in first housing 110, and the first guide protrusions 121 may protrude from one side of the first guide 120 while being equally spaced apart from each other.
[0094] Next, as illustrated in
[0095] A third coupling portion 230 and a second coupling portion 220 protrude from one end and the other end of the second housing 210, respectively.
[0096] As illustrated in
[0097] As illustrated in
[0098] As illustrated in
[0099] As illustrated in
[0100] As illustrated in
[0101] As illustrated in
[0102] In particular, as illustrated in
[0103] As illustrated in
[0104] In particular, the disposable safety syringe needle 1 is configured such that the latch protrusion 320, which has moved down to the latch recess 244, is latched by the protruding surface of the latch stepped portion 243, thereby being prevented from moving up again. Thus, it is impossible to forcibly reuse the disposable safety syringe needle 1, so that puncture wounds or injuries that could otherwise be caused by the needle member can be advantageously prevented.
[0105] In addition, even when the user pushes the latch protrusion 320 latched by the latch recess 244 with a fingernail or a tool, the latch protrusion 320 latched by the protruding surface of the latch stepped portion 243 cannot move up again. Consequently, it is advantageously possible to prevent tampering by a user.
[0106] As illustrated in
[0107] As illustrated in
[0108] In particular, a plurality of latch portions 240 are formed at equal distances on outer peripheral portions of the second housing 210. At the initial step, the safety part 30 is balanced, and minute force of the free length of the elastic member 40 is endured. Thus, the safety part 30 is advantageously prevented from moving down toward the latch recess 244.
[0109] In addition, the plurality of latch portions 240 are formed at equal distances on the outer peripheral portions of the second housing 210, and the safety part 30 is introduced in the balanced position. Thus, a structure in which the latch protrusion 320 is moved over the latch stepped portion 243 to be locked to the latch recess 244 by the tension of the compressed elastic member 40 is advantageously formed.
[0110] When a single latch portion 240 is formed on an outer peripheral portion of the second housing 210, the safety part 30 may be introduced in an unbalanced position, so that the latch protrusion 320 may fail to move over the latch stepped portion 243. Consequently, a third person may be injured or infected by the needle member.
[0111] As illustrated in
[0112] A third hole 330 is formed in one end of the third housing 310, and the latch protrusion 320 protrudes from the other end of the third housing 310.
[0113] In addition, the third housing 310 surrounds the needle member 50 therein, such that the needle member 50 is not exposed before use of the disposable safety syringe needle 1. Injuries that could be caused by the needle member are advantageously prevented.
[0114] As illustrated in
[0115] In addition, the inner surface of the latch protrusion 320 is coupled to the elastic member 40, such that the safety part 30 is movable vertically up and down. Thus, the structure by which the needle member 50 is concealed and exposed can prevent injuries and infections that could be caused by the needle member.
[0116] In particular, when the outer surface of the latch protrusion 320 is fixed by latching to the latch recess 244, the latch protrusion 320 cannot move up again, thereby preventing the disposable safety syringe needle 1 from being reused. Consequently, a medical accident that could be caused by the reuse of the disposable safety syringe needle 1 can be prevented.
[0117] The third hole 330 is a hole formed on one end of the third housing 310. During use of the disposable safety syringe needle 1, the needle member 50 is exposed from the third housing 310 through the third hole 330.
[0118] As illustrated in
[0119] As illustrated in
[0120] The compression spring is a spring resisting to compression force. That is, since the compression spring is used, after the safety part 30 is introduced into the bottom part 20 in the direction of the top part 10 due to the compression, the latch protrusion 320 of the safety part 30 may be coupled to the one or more latch portions 240 due to the tension of the elastic member 40, thereby providing a non-reusable structure.
[0121] As illustrated in
[0122] In addition, the outer diameter of the needle member 50 may be set to range from 0.2 mm to 1.7 mm; but is not limited thereto. The outer diameter of the needle member 50 may vary depending on the intended use.
[0123] When the outer diameter of the needle member 50 is less than 0.2 mm, it is difficult to inject a medicine into a patient using the disposable safety syringe needle 1 although the patient is less painful. In particular, it is more difficult to inject a high viscosity medicine.
[0124] In addition, when the needle member 50 is formed slender, the needle member 50 is easily breakable, and thus the length thereof is limited.
[0125] When the outer diameter of the needle member 50 is greater than 1.7 mm, pain applied to the patient may be significantly increased, which is problematic.
[0126] In addition, the outer diameter of the needle member 50 may be categorized according to the intended use.
[0127] That is, when the needle member 50 is intended to be used for intravenous injection, the outer diameter of the needle member 50 may be set to range from 0.56 mm to 1.6 mm. When the needle member 50 is intended to be used for intramuscular injection, the outer diameter of the needle member 50 may be set to range from 0.6 mm to 0.86 mm.
[0128] In addition, when the needle member 50 is intended to be used for subcutaneous injection, the outer diameter of the needle member 50 may be set to range from 0.25 mm to 0.5 mm. When the needle member 50 is intended to be used for intradermal injection, the outer diameter of the needle member 50 may be set to range from 0.4 mm to 0.5 mm.
[0129] The disposable safety syringe needle 1 having the above-described configuration may be operated by a use method, as illustrated in
[0130] As illustrated in
[0131] Here, in the first step, the needle member 50 exposed from the second support portion 150 is surrounded inside the third housing 310, so that the needle member 50 is not exposed to the outside from the safety part 30. Thus, it is possible to prevent injuries from being caused by the needle member.
[0132] Afterwards, as illustrated in
[0133] In addition, in the second step, the outer peripheral portion of the latch protrusion 320 is introduced into the second housing 210 by a length by which the elastic member 40 is compressed.
[0134] Here, as the safety part 30 is introduced into the bottom part 20, the needle member 50 that has been within the third housing 310 is exposed to the outside. The needle member 50 does not move while being fixed to the second support portion 150.
[0135] Afterwards, as illustrated in
[0136] That is, the needle member 50 that has been exposed is surrounded again by the third housing 310, thereby being concealed in the safety part 30.
[0137] Due to the tension of the elastic member 40, the plurality of third support portions 242 prevent the outer surface of the latch protrusion 320 from being released through the latch indicator 241.
[0138] In addition, the outer surface of the latch protrusion 320 is accelerated along the inner inclined surfaces of the plurality of latch stepped portions 243. Due to the tension and acceleration, the outer surface of the latch protrusion 320 moves over the inner protruding surfaces of the plurality of latch stepped portions 243, thereby being latched by the latch recess 244.
[0139] In particular, the latch protrusion 320 is configured such that the outer peripheral portion thereof does not contact the inner surface of the second housing 210 so as not to generate friction. Thus, when the outer surface of the latch protrusion 320 moves vertically up and down along the inner inclined surfaces of the plurality of latch stepped portions 243, the outer surface of the latch protrusion 320 may be advantageously accelerated.
[0140] Furthermore, as the latch protrusion 320 latched by the plurality of latch recesses 244 is also latched by the protruding surface of the latch stepped portion 243, the latch protrusion 320 cannot move up again. Thus, the disposable safety syringe needle 1 cannot be reused, and the needle member 50 is not exposed from the safety part 30.
[0141] That is, since the needle member 50 is not exposed, a third person can advantageously be prevented from being injured or infected by the needle member 50 after use.
[0142] In addition, due to the structure preventing the safety part 30 from moving up again, tampering by a user can be prevented, thereby fundamentally preventing reuse. Accordingly, infection caused by reuse as well as infection caused by viruses, such as the AIDS virus, or bacteria can be prevented.
Mode for Invention
Second Embodiment
[0143] A disposable safety syringe needle 1, the same as that of the first embodiment as described above, may further include a sealing part 60.
[0144] The disposable safety syringe needle 1 is configured the same as that of the first embodiment, and thus a description thereof will be omitted.
[0145] The sealing part 60 may be removed to prevent the sterilized disposable safety syringe needle 1 from being contaminated before transportation or use thereof, and be formed of a synthetic resin or paper.
[0146] As illustrated in
[0147] As illustrated in
[0148] In addition, before the sealing part 60 is removed, the first sealing portion 61 may be manufactured to be transparent so that a user may easily identify the state of the disposable safety syringe needle 1 from the outer appearance of the first sealing portion 61.
[0149] The outer surface of the safety part 30 is positioned inside one end of the first sealing portion 61, and the outer surface of the top part 10 is positioned inside the other end of the first sealing portion 61.
[0150] In addition, a plurality of first anti-slip portions (not shown) are formed at equal distances on the outer peripheral surface of the first sealing portion 61. When the second sealing portion 62 is removed, it is advantageously possible to prevent the first sealing portion 61 from slipping away from the hand of the user.
[0151] Furthermore, a plurality of second anti-slip portions (not shown) may be formed at equal distances on the inner surface of the other end of the first sealing portion 61.
[0152] The first anti-slip portions and the second anti-slip portions may be formed in the same shape as the first guide protrusions 121 as illustrated in
[0153] The second anti-slip portions are fitted to recesses alternating with the first guide protrusions 121 formed at equal distances, so that there is an advantage in that the disposable safety syringe needle 1 is immovably fixed within the sealing part 60.
[0154] The second sealing portion 62 is formed on the other end of the first sealing portion 61 to prevent the disposable safety syringe needle 1 from being contaminated. The second sealing portion 62 may be formed of sterilized paper which is removable.
[0155] Since the sealing part 60 is further included in the disposable safety syringe needle 1, a step of removing the sealing part 60 may be performed before use of the disposable safety syringe needle 1.
Third Embodiment
[0156] A syringe device 2 may include the disposable safety syringe needle 1 according to the first embodiment or the second embodiment.
[0157] The disposable safety syringe needle 1 is configured the same as that of the first embodiment or the second embodiment, and thus a description thereof will be omitted.
[0158] The syringe device 2 may include a syringe or an automatic syringe.
[0159] The syringe may be implemented as a well-known syringe. For example, as illustrated in
[0160] When the disposable safety syringe needle 1 is coupled to the syringe; a user (i.e., a medical personnel) can be advantageously relieved from the stress of being pricked by the needle.
[0161] In addition, when the syringe including the disposable safety syringe needle 1 is discarded, a person carrying the syringe can be advantageously prevented from being injured or infected by being pricked by the used needle.
[0162] The automatic syringe is a syringe designed to inject a medicine. The automatic syringe may be categorized as a pump type syringe or a pen type syringe, and inject a medicine once or several times.
[0163] In a situation in which the disposable safety syringe needle 1 is coupled to the automatic syringe, when the syringe is discarded, the needle member 50 is not exposed even if the syringe is not covered with a separate safety cap. Thus, there are advantages in that no injuries occur and a discard process is convenient.
[0164] The medicine may include one or more selected from, but is not limited to, insulin, hormone, low-molecular-weight heparin, or derivatives thereof.
[0165] A method of coupling the disposable safety syringe needle 1 and the syringe device 2 may include introducing a needle-coupling portion of the syringe device 2 into the other end of the first housing 110 of the disposable safety syringe needle 1.
INDUSTRIAL APPLICABILITY
[0166] The present disclosure relates to a disposable safety syringe needle configured to prevent reuse thereof as well as accidents in which the needle causes injury and a syringe device including the same. Accordingly, the present disclosure is industrially applicable.
