Description

Description SAFETY FILTER TIP FOR A SYRINGE
Technical Field
[1] The present invention relates to a safety filter tip for a syringe, and in particular to a safety filter tip for a syringe which makes it possible to use a syringe in safe by effectively preventing part of glass particles from being inputted into a syringe when removing an ample glass bottle, and since it is made of a plastic material, a syringe needle can be prevented from pricking an operator.
[2]
Background Art
[3] Generally, a syringe is widely used for injecting a medicine into a human body.
[4] As shown in Figure 1, a conventional syringe 1 comprises a cylindrical cylinder 10 having a space for storing an injection liquid, and a syringe tip 20 connected with a neck part 15 formed in a front side of the cylinder 10.
[5] The syringe tip 20 is equipped with a hub 25 for connecting a syringe needle 22 to the cylinder 10. The hub 25 is inserted into the neck part 15 of the syringe 1. The syringe 1 is equipped with a plunger 30 which is movably inserted into the interior of the cylinder 10 for sucking an injection liquid into the interior of the cylinder 10 or discharging the injection liquid stored in the cylinder 10 to the outside.
[6] The conventional syringe 30 makes the plunger 30 closer to the front side in the interior of the cylinder 10 for injecting an injection liquid into a patient, and an upper side 42 of an ample is broken and open by applying a certain force to the upper side 42 of the ample glass bottle 40 which stores the injection liquid 60. The syringe needle 22 is inputted through the opened upper side 42. In this state, the plunger 60 is moved back for thereby sucking the injection liquid 60 into the interior of the cylinder 10.
[7] When the upper side 42 of the ample glass bottle 40 is broken and open, the glass particles K broken during the opening of the ample glass bottle fly, and part of the glass particles K might be inputted into the interior of the injection liquid 60 of the ample glass bottle 40. The glass particles K inputted into the interior of the injection liquid 60 is inputted into the interior of the syringe 1 along with an injection liquid 60 when sucking the injection liquid 60 using the syringe 1. When the injection liquid 60 is inputted into the body of the patient, the above glass particles are also inputted into the body of the patient, so the glass particles might hurt the health of the patient.
[8]
Disclosure of Invention Technical Problem [9] Accordingly, it is an object of the present invention to provide a safety filter tip for a syringe which makes it possible to use in safe by effectively preventing a glass particle from being inputted from an injection liquid when opening an ample glass bottle into a body of a patient. In addition, it is possible to prevent an operator from being pricked by needles since the number of needle uses can be decreased. As a result, a certain infection through an injection needle can be significantly prevented, and a safe and reliable injection can be obtained during an operation.
[10]
Technical Solution
[11] To achieve the above objects, in a syringe tip fixed in a neck part of a front side a syringe, there is provided a safety filter tip for a syringe which comprises a hub which is inserted into the neck part of a syringe; a suction part which is integrally formed in a front side of the hub preferably based on a molding way; and a filter which is fixed in an inner side of the hub, whereby glass particles contained when opening an ample glass bottle can be reliably filtered and removed by means of the filter when sucking injection liquid from the ample glass bottle.
[12] The hub is equipped with an engaging shoulder protruded from an inner side of the hub, and a front side of the filter is closely contacted, and the filter is fixed in the hub by tightly inserting a bushing into a rear side of the filter.
[13] The engaging shoulder has a certain interval between the suction part and itself, and the filter forms a certain space between the suction part and itself in the hub.
[14] The bushing is tightly inserted and fixed by forming a concave part in an inner side of the hub.
[15] The filter is provided with a plurality of pores with 5μm sizes for reliably filtering glass particles.
[16]
Advantageous Effects
[17] In the present invention, since a filter is fixed in a hub, the glass particles, which might be mixed in an injection liquid, can be reliably filtered by means of a filter when an ample glass bottle is broken and open, and an injection liquid is sucked into a syringe. So, the glass particles can be reliably filtered and removed from an injection liquid for thereby basically preventing the glass particles from being inputted into a human body. A safe use of injection liquid can be obtained.
[18] In addition, since a tip is made of a plastic material, an operator can be prevented from being pricked by needles for thereby significantly reducing an infection danger by bacteria in safe. Since the use of needles can be reduced, the consumption of goods can be advantageously reduced. [19]

[24]
Best Mode for Carrying out the Invention
[25] In a syringe tip fixed in a neck part of a front side a syringe, a safety filter tip for a syringe comprises a hub which is inserted into the neck part of a syringe; a suction part which is integrally formed in a front side of the hub preferably based on a molding way; and a filter which is fixed in an inner side of the hub, whereby glass particles contained when opening an ample glass bottle can be reliably filtered and removed by means of the filter when sucking injection liquid from the ample glass bottle.
[26]
Mode for the Invention
[27] The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[28] The safety filter tip 100 for a syringe according to the present invention is fixed to a neck part 15 of a front part of a syringe 1. As shown in Figure 2, the safety filter tip 100 for a syringe is equipped with a hub 110 inserted into the neck part 15 of the syringe 1, and the hub 110 is equipped with a sharp injection liquid suction part 115 made of a plastic material by a molding way and integrally disposed in a front side of the same.
[29] Namely, the suction part 115 is made similarly with a conventional needle, with an injection liquid being sucked through the interior of the suction part 115.
[30] A filter 120 is disposed in an inner side of the hub 110. The filter 120 is equipped with 5μm size pores for reliably filtering glass particles.
[31] The safety filter tip 100 for a syringe according to the present invention is configured to engage a filter 120 in the interior of the hub 110 using an engaging shoulder 122 and a bushing 130. The hub 110 is equipped with an engaging shoulder 122 in its inner side with a front side of the filter being closer to the engaging shoulder 122. The bushing 130 is inserted into a rear side of the filter 120 for reliably fixing the filter 120 to the hub 110.
[32] In the above structure, the front side of the filter 120 is supported by means of the engaging shoulder 122, and the rear side of the same is fixed by means of a ring shaped bushing 130, so the filter 120 is stably fixed in the interior of the hub 110.
[33] The engaging shoulder 122 has a certain interval from the suction part 115. The filter
120 has a certain sized space part 140 in the hub 110 between itself and the suction part 115. Here, the space part 140 has an important function for filtering glass particles K by means of the filter 120. The space part 140 is configured to allow the glass particles K to spread widely when the injection liquid is inputted into the interior of the hub 110 through the suction part 115, so the glass particles K are spread in the spread part 140 and are filtered in the whole spaces of the filter 120.
[34] When the space part 140 is not formed, namely, in a state that the filter 120 is close to the small sized holes 115a of the suction part 115, the holes 115a of the suction part 115 might be closed by means of the filter 120. Namely, the injection liquid might be filtered only in the portions of the filter 120 which is close to the small sized holes 115a of the suction part 115. So, the whole portions of the filter 120 might not be used.
[35] However, in the present invention, since a space part 140 is formed between the filter
120 and the suction part 115, a filtering function might be obtained on the whole portions of the filter 120, and it is possible to prevent the holes 115a of the suction part 115 from being blocked.
[36] The bushing 130 is tightly inserted into the hub 110 with the help of a round concave part 133 formed in an inner side of the hub 110. In the above structure, the bushing 130 is inserted from the rear side of the hub 110 into the concave part 133, so the bushing 130 is rightly inserted into the round concave part 133. With the above construction, the filter 120 is not easily escaped in the backward direction.
[37] As shown in Figure 4A, the safety filter tip 100 for a syringe according to the present invention sucks an injection liquid 60 into the interior of the cylinder 10 for injecting the injection liquid 60 into a patient. When the ample glass bottle 40 is broken and open, and part of the glass particles K is inputted into the injection liquid 60, the injec tion liquid 60 is sucked into the interior of the cylinder 10 through the suction part 115 of the hub 110 and the filter 120. In this state, the filter 120 reliably filters the glass particle K contained in the injection liquid 60. So, only the injection liquid without glass particles K can be inputted into the interior of the cylinder 10 of the syringe.
[38] After the above operation is finished, as shown in Figure 4B, the hub 110 is pulled out from the neck part 15 of the syringe 1, and a new syringe tip 20 is connected, and the plunger 30 of the cylinder 10 is pushed forwardly, and the injection liquid 60 is inputted into the body of the patient through the injection needle 22 of the syringe tip 20 by means of the above pushing pressure. Since the glass particles K are already filtered from the injection liquid 60 in the cylinder 10 through the above operations by means of the filter 120, only the injection liquid 60 without glass particles K is inputted into the body of the patient.
[39] In the present invention, since the filter 120 is fixed in the hub 110, the glass particles
K mixed in the injection liquid 60 when opening the ample glass bottle are reliably filtered and removed by means of the filter 120 when being sucked into the cylinder 10. When an injection liquid is inputted into the body of the patient, it is possible to effectively prevent the glass particles K from being inputted into the body of a patient, so the injection liquid 60 stored in the ample glass bottle 40 can be used in safe.
[40] Since the tip is made of a plastic material, the operator can be prevented from being pricked by needles, so a certain bacteria infection can be prevented for thereby obtaining an operation safety. Only when the injection needle 22 is used only when injecting an injection liquid, over use of the injection needles can be prevented, so the consumption cost of needles can be significantly reduced.
[41] The present invention was described in details in relation with a specific embodiment with reference to the accompanying drawings, but the disclosed contents are not limited to a specific structure. It is obvious that those who skilled in the art can modify or amend in various forms without departing from the technical concepts and scopes of the present invention. For example, the filter 120 is fixed in the hub 110 with the helps of the engaging shoulder 122 and the bushing 130, but in different manner, a fixing groove(not shown) might be formed for directly engaging the filter. Namely, the filter might be fixed in the hub in various manners. It is obvious that such a simple structure change or modification might belong to the scope of the present invention.
[42]
Industrial Applicability
[43] In the present invention, since a filter is fixed in a hub, the glass particles, which might be mixed in an injection liquid, can be reliably filtered by means of a filter when an ample glass bottle is broken and open, and an injection liquid is sucked into a syringe. So, the glass particles can be reliably filtered and removed from an injection liquid for thereby basically preventing the glass particles from being inputted into a human body. A safe use of injection liquid can be obtained.
[44] In addition, since a tip is made of a plastic material, an operator can be prevented from being pricked by needles for thereby significantly reducing an infection danger by bacteria in safe. Since the use of needles can be reduced, the consumption of goods can be advantageously reduced.
