Description

The present invention relates to a sealed connector, and more particularly to a sealed connector with a compressible butt joint for aspirating residual chemicals during the disassembly process.

When the needleless syringe is replenished with a drug solution, it is connected to the drug vial through a sealed connector, and the drug solution in the drug vial is aspirated and enters the syringe through the joint.

A conventional sealed connector includes a first connecting piece and a second connecting piece. The first connecting piece includes a first sleeve, an elastomer and a coupling. The second connecting component includes a second sleeve, a communicating tube, a first elastic valve and a second elastic valve. A syringe or infusion tube is removably connected to the coupling. The second sleeve is removably connected to the vial or body-end conduit. In the process of abutting the first connecting part and the second connecting part, the first conduit of the first sleeve compresses the first elastic valve and bends and deforms the first elastic valve to open the slit. .

The communication pipe passes through the slit of the first elastic valve and the opening of the first conduit in order to enter the interior of the first conduit. The communicating pipe pushes the elastomer to bend and deform it. The through hole is exposed outside the first resilient valve and located inside the first conduit. The communicating pipe further compresses the second elastic valve and bends and deforms the second elastic valve to open the slit. The first elastic valve then continues to push the communicating tube downward until the communicating tube passes through the slit of the second elastic valve and enters the second conduit of the second sleeve. Thereby, the inside of the first sleeve and the inside of the second sleeve communicate with each other.

When preparing the drug solution, the drug solution in the vial can enter the syringe through the second conduit, the communication tube, the first conduit and the joint in order. When injecting or transporting the drug solution, the drug solution in the syringe or the infusion tube can enter the human body through the connecting part, the first conduit, the communication tube, the second conduit, and the body end conduit in order. After the preparation of the liquid medicine or the injection or transportation of the liquid medicine is completed, the first connecting part and the second connecting part are disassembled again, and the liquid medicine remains on the outer surface of the communicating tube.

In the process of disassembling the first connecting part and the second connecting part, part of the chemical solution remaining on the outer surface of the communicating tube was scraped off by the first conduit, but was completely scraped off. Hateful. Therefore, a small amount of the chemical solution remains on the outer surface of the communicating pipe. Some medical fluids (eg, chemotherapy drugs) are cytotoxic, thus jeopardizing the patient's or medical personnel's health if residual medical fluid comes into contact with the patient's or medical personnel's skin or is inhaled into their lungs.

Furthermore, if the infusion tube is used in a place where there is not enough space, the infusion tube may be twisted and the liquid medicine may not be transported smoothly. Generally, it is processed as follows. First, the first connecting part is rotated and removed from the infusion tube. Then, straighten the twisted infusion tube. Finally, a straight infusion tube is removably connected to the first connecting piece. According to the above method, the problem of twisting of the infusion tube can be solved, but the operation is troublesome and there is a risk of drug leakage.

A primary object of the present invention is to provide a sealed connector with a compressible butt joint for aspirating residual chemicals during the disassembly process. According to the present invention, it is possible to effectively prevent the drug solution from remaining on the outer surface of the communicating tube, thereby reducing the risk of the residual drug solution contacting the patient's or medical worker's skin or being inhaled into the lungs.

The sealing portion 62 is provided at the top end of the annular peripheral portion 61 and has a slit 621 . The annular peripheral portion 61 presses the sealing portion 62 by its elastic force, and the second opening 423 is sealed by the sealing portion 62 .

The second elastic valve 70 is provided inside the second cylindrical body 42 and has an annular peripheral portion 71 and a sealing portion 72 . The annular peripheral portion 71 is annularly provided on the outer side of the lower column portion 53 and abuts on the large diameter portion 52 at its top end. The elastic force of the annular peripheral portion 71 pushes the large diameter portion 52 , and the large diameter portion 52 further pushes the upper pillar portion 51 , thereby positioning the upper pillar portion 51 within the slit 621 . The sealing end 511 of the upper column 51 is aligned with the top end of the slit 621 and the through hole 512 is sealed by the sealing portion 62 .

The sealing portion 72 keeps the slit 721 closed by its elastic force, and the inside of the lower column portion 53 is sealed by the sealing portion 72 .

The first connecting part 1 is fixed to the syringe 100 and the second connecting part 2 is fixed to the vial 200 before preparing the drug solution. Since the slit 721 is kept closed, the drug solution in the drug vial 200 enters only the second conduit 412 and does not enter the communicating tube 50 .

Before injecting or transporting the drug solution, the first connecting part 1 is fixed to the syringe 100 or the infusion tube, and the second connecting part 2 is fixed to the duct at the end of the human body. Since the first opening 131 is sealed by the sealing portion 32 , the medical solution in the syringe 100 or the infusion tube cannot flow out through the first opening 131 .

Description will be made with reference to FIG. In the process of abutting the first connecting part 1 and the second connecting part 2, the upper column part 51 pushes the sealing part 32, the sealing part 32 compresses the annular peripheral part 31, and the air in the accommodation space 311 is released. It enters the inside of the first conduit 13 through the suction hole 313, the suction hole 313 is deformed and sealed, and the receiving space 311 is in a vacuum state. The upper post 51 passes through the first opening 131 into the interior of the first conduit 13 and the first conduit 13 pushes against the seal 62 .

The through hole 512 of the upper column 51 is exposed outside the sealing portion 62 and located inside the first conduit 13 . The annular peripheral portion 61 pushes the large diameter portion 52 , the large diameter portion 52 compresses the annular peripheral portion 71 , and the annular peripheral portion 71 is bent and deformed. In that case, the annular peripheral portion 71 pushes the communicating pipe 50 and moves downward. The lower post 53 expands the slit 721 and passes through the slit 721 to enter the interior of the second conduit 412 . After the first cylindrical body 41 is inserted into the sleeve portion 11 , the stabilizing structure 44 abuts against the inner wall of the sleeve portion 11 .

Thereby, the inside of the connecting portion 20, the first conduit 13, the communicating pipe 50, and the inside of the second conduit 412 are in communication. The protrusion 43 moves into the hole 111 and the hook 125 hooks the bottom end of the protrusion 43 .

Preferably, a groove 110 is formed between the handle portion 123 and the sleeve portion 11, as shown in FIG. As shown in FIG. 5, the sealed connector further has a safety ring portion 80 . The safety ring portion 80 includes a jacket portion 81 and an annular portion 82 . The jacket portion 81 is movably provided on the sleeve portion 11 . The annular portion 82 is provided at the top end of the jacket portion 81 . After the first connecting part 1 and the second connecting part 2 are butted against each other, the jacket part 81 moves into the groove 110 along the sleeve part 11 , whereby the jacket part 81 is locked in the groove 110 . be done. The annular portion 82 abuts the top end of the handle portion 123 .

If the patient accidentally pushes the handle 123, the jacket 81 can stop the handle 123 and prevent the other end of the holding arm 122 from rotating. Since the hook portion 125 can continue to hook the bottom end of the projecting portion 43, the first connecting part 1 and the second connecting part 2 can be maintained in a butting state without being disassembled.

When preparing the drug solution, the drug solution in the drug bottle 200 can flow into the syringe 100 through the second conduit 412, the communication tube 50, the first conduit 13, and the coupling part 20 in order. .

When injecting or transporting a drug solution, the drug solution in the syringe 100 or the infusion tube is sequentially passed through the interior of the coupling part 20, the first conduit 13, the communication tube 50, the second conduit 412, and the conduit at the end of the human body. can enter the human body.

If the second end 22 is fixed to the infusion tube and the infusion tube is severely torsionally deformed for some reason, the projection 43 can optionally rotate in the first direction and the second direction along the hook portion 125. By doing so, the first connecting part 1 can be arbitrarily rotated with respect to the second connecting part 2 along the first direction and the second direction. Therefore, on the premise that the liquid medicine does not leak, the liquid medicine in the infusion tube can flow smoothly by twisting the infusion tube linearly.

After the preparation of the medical solution or the injection or transportation of the medical solution is completed, the first connecting part 1 and the second connecting part 2 are again disassembled. The chemical solution remains on the outer surface of a portion of the upper column portion 51 located inside the first conduit 13 .

In the process of disassembling the first connecting part 1 and the second connecting part 2, first, the user grasps the annular part 82 with his fingers and moves it upward, and the jacket part 81 moves along the sleeve part 11. to separate it from the concave groove 110 . The handle 123 is released from the stop of the jacket portion 81 and can be pushed, allowing the other end of the clamping arm 122 to freely pin. By pushing the handle 123 , the other end of the clamping arm 122 is pinned outward to separate the hook 125 from the projection 43 .

The annular peripheral portion 71 pushes the large diameter portion 52 by its elastic force, moving the communicating pipe 50 and the first elastic valve 60 upward, and the lower column portion 53 moves upward and separates from the second conduit 412 . , inside the annular circumference 71 . The sealing part 72 completely closes the slit 721 by its elastic force, and the sealing part 72 seals the inside of the lower column part 53 . Since the inside of the communicating tube 50 and the second conduit 412 are blocked, the sealing performance of the inside of the second connecting part 2 can be improved, and reflow of the drug solution from the drug vial 200 into the communicating tube 50 can be prevented.

The elastic force of the annular peripheral portion 61 pushes the sealing portion 62 to move it upward, and further moves it upward along the outer side of the upper column portion 51 . The sealing part 62 pushes the first conduit 13 by its elastic force, moves the first connecting part 1 , and the upper column part 51 separates from the first conduit 13 and returns into the sealing part 62 .

What is important here is that the seal 62 continues to abut the first conduit 13 during the upward movement and that the upper post 51 remains within the open slit 621 and within the first conduit 13 . to continue. Thereby, the distance between the interior of the first end 21 and the interior of the second end 422 is not increased.

Furthermore, in the process of disassembling the first connecting part 1 and the second connecting part 2, the sealing part 62 continues to move upward to cover the through-hole 512, so that the inside of the first conduit 13 and the The communication with the inside of the communicating pipe 50 is cut off. As a result, the liquid medicine does not flow into the inside of the first conduit 13 or the inside of the communicating tube 50 from the through hole 512 . In this case, the upper column portion 51 maintains the state in which the slit 621 is expanded, and the through hole 512 is sealed by the sealing portion 62 .

Finally, in the process of disassembling the first connecting part 1 and the second connecting part 2, the upper column 51 gradually separates from the first conduit 13 through the first opening 131, and the slit 621 go back inside. A sealing portion 62 seals the through hole 512 . In the process of separating upper column 51 from first conduit 13 , first conduit 13 contacts the outer surface of upper column 51 . In the process of the first elastomer 30 returning to its original shape due to its elastic force, the annular peripheral part 31 pushes the sealing part 32 back to its original position due to its elastic force, and the sealing part 32 closes the first opening 131 . Seal. Therefore, the chemical solution does not circulate inside the first conduit 13 from the first opening 131 .

The suction hole 313 is restored to its original shape and opened, the air inside the first conduit 13 enters the accommodation space 311 through the suction hole 313 to generate negative pressure. The chemical liquid on the outer surface of the upper column portion 51 enters the inside of the first conduit 13 due to the scratching action of the first conduit 13 and the suction action of the negative pressure, and the chemical liquid inside the first conduit 13 becomes negative. It is gathered in the receiving space 311 through the suction hole 313 by the suction effect of the pressure.

As a result, the chemical does not remain on the outer surface of the upper column portion 51 at all. Also, the liquid medicine collected in the housing space 311 does not flow out through the first opening 131 . Therefore, the risk of residual drug liquid contacting the patient's or health care worker's skin or being inhaled into the lungs can be reduced.

Furthermore, in the process of installing the first connecting part 1 , the ring-shaped circumference 31 is positioned in the positioning groove 14 , and the first end 21 is inserted into the sleeve section 11 to press the top end of the ring-shaped circumference 31 . Therefore, attachment is easy and separation of the first elastomer 30 from the first sleeve 10 can be prevented.

Since the stabilizing structure 44 is annular and abuts against the inner wall of the sleeve portion 11 , the second sleeve 40 does not shake within the sleeve portion 11 .

In addition, bending deformation of the sealing portion 32 can be prevented by the support ribs 132 in the process of butting the first connecting part 1 and the second connecting part 2 together. As a result, the sealing portion 32 maintains its axial motion to compress the annular peripheral portion 31 , thereby ensuring the discharge of air from the accommodation space 311 and the deformation and sealing of the suction hole 313 .

In the process of butting the first connecting part 1 and the second connecting part 2 together, the stopper part 23 can prevent the middle part of the ring-shaped peripheral part 31 from moving upward and deforming. Compression of the annular peripheral portion 31 by the portion 32 becomes more reliable, and the air in the accommodation space 311 can be completely discharged. Therefore, the accommodation space 311 becomes a vacuum state.

In addition, the stopper portion 23 can prevent the liquid medicine from flowing into the housing space 311 through the opening 314 , thereby ensuring that the housing space 311 is maintained in a vacuum state.

Additionally, the second end 422 has male threads so that a user can screw the second end 422 onto a syringe (not shown). In other words, the second connecting piece 2 can not only butt against the first connecting piece 1, but also against a syringe.

It should be noted that the second end 22 is substantially equivalent to a conventional luer taper female fitting. Due to the combination of the second end 22 and the clamping part 12, the first connecting piece 1 has the function of a conventional luer taper female joint and the clamping function at the same time. Therefore, the first connecting piece 1 can simultaneously couple a syringe 100 or an infusion tube having a conventional luer taper male joint and the second connecting piece 2 .

Description will be made with reference to FIG. The difference between Example 2 and Example 1 is as follows.

1. The first conduit 13A further has a sealing ring portion 134 formed with a locking portion 133 at its bottom end and made of a soft material.

The first clip portion 34 includes a recess 341 located inside the sealing portion 32A and a notch 342 located at the bottom end of the sealing portion 32A. The diameter of notch 342 is smaller than the maximum diameter of recess 341 .

3. Communicating tube 50A includes second clip portion 54 having neck portion 541 and head portion 542 . A neck portion 541 is provided protruding from the sealed end 511A, and a head portion 542 is provided at one end of the neck portion 541 . The diameter of neck 541 is smaller than the maximum diameter of head 542 . The size and shape of head 542 correspond to the size and shape of recess 341 . The size and shape of neck 541 corresponds to the size and shape of notch 342 .

The structure of Example 2 is the same as that of Example 1 except for the above three points.

Before injecting or transporting the drug solution, the differences between Example 2 and Example 1 are as follows. In Example 2, since the first opening 131A is sealed by the sealing portion 32A, the drug solution in the syringe 100 or the infusion tube cannot flow out through the first opening 131A.

Regarding Example 2, the difference from Example 1 in the process of butting the first connecting part 1A and the second connecting part 2A is as follows.

1. The second clip portion 54 is locked to the first clip portion 34 by inserting the head portion 542 into the recess 341 and positioning the neck portion 541 in the notch 342 .

2. The sealing portion 32A is separated from the sealing ring portion 134 by pushing the sealing portion 32A with the upper column portion 51A.

3. The upper post 51A in turn passes through the first opening 131A and the sealing ring portion 134 into the interior of the first conduit 13A.

4. The sealing ring portion 134 presses against the sealing portion 62 .

Except for the above four points, the matching process of the second embodiment is the same as the matching process of the first embodiment.

Regarding Example 2, in the process of disassembling the first connection component 1A and the second connection component 2A, differences from Example 1 are as follows.

1. The sealing part 62 pushes the sealing ring part 134 by its elastic force, moves the first connecting part 1A, and the upper column part 51A separates from the sealing ring part 134 and returns into the sealing part 62 .

2. Finally, the second clip portion 54 is extracted from the inside of the first clip portion 34, and the first clip portion 34 and the second clip portion 54 are disassembled.

3. In the process of separating the upper column portion 51A from the sealing ring portion 134, the sealing ring portion 134 contacts the outer surface of the upper column portion 51A.

4. In the process of the first elastomer 30A returning to its original shape due to its elastic force, the elastic force of the annular peripheral part 31A pushes the sealing part 32A back to its original position. to seal the first opening 131A.

5. The chemical solution on the outer surface of the upper pillar 51A enters the first conduit 13A due to the scratching action of the sealing ring part 134 and the suction action of the negative pressure. are collected in the housing space 311A through the suction holes 313A by the suction action of the .

The decomposition process of Example 2 is the same as the decomposition process of Example 1 except for the above five points.

As a result, no chemical solution remains on the outer surface of the upper column portion 51A. Also, the liquid medicine collected in the accommodation space 311A does not flow out from the first opening 131A. Therefore, the risk of residual drug liquid contacting the patient's or health care worker's skin or being inhaled into the lungs can be reduced.
