Description

Technical Field

[0001] This invention relates to the field of hemodialysis technology, specifically to a disinfection, sealing, and fixing device for the connector of an internal jugular vein dialysis catheter. Background Technology

[0002] When disembarking from hemodialysis, the internal jugular vein dialysis catheter connector needs to be disinfected, wrapped, and secured. Medical staff should prepare a catheter care kit containing items such as a tray, sterile gloves, sterile drapes, disinfectant, 0.5% iodine gauze, iodine balls, and a heparin cap. After disconnecting the internal jugular vein dialysis catheter connector from the hemodialysis machine, medical staff put on sterile gloves, laid a sterile drape under the internal jugular vein dialysis catheter connector, wiped the connector with disinfectant for 15 seconds, then screwed the heparin cap onto the connector, and wiped the threaded end of the internal jugular vein dialysis catheter connector with an iodine ball to remove blood crusts from the thread grooves and prevent infection; wiped with 0.5% iodine gauze for disinfection, and finally wrapped the internal jugular vein dialysis catheter connector with sterile gauze, and then secured it with a piece of medical tape to prevent the sterile gauze from falling off, and then used another piece of medical tape to attach it to the dialysis patient's ear.

[0003] The entire procedure was performed in the dialysis clinic, and the entire process was completely exposed to the air. Although medical staff wore sterile gloves, they inevitably came into contact with other items during the procedure. Once they came into contact with other items, the internal jugular vein dialysis catheter connector could easily become contaminated. Moreover, the entire procedure was performed in an exposed state, which also made it easy for contamination to occur. Furthermore, when hospital staff used medical tape to stick the wrapped internal jugular vein dialysis catheter connector behind the ear, it was easy for it to fall off. After the medical tape fell off or was torn off, it could easily leave adhesive residue on the skin. Summary of the Invention

[0004] To address the shortcomings of the existing technology, the present invention provides a disinfection, sealing, and fixing device for the internal jugular vein dialysis catheter connector that reduces contamination and prevents detachment.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] The internal jugular vein dialysis catheter connector disinfection, sealing and fixing device includes an outer shell, a disinfection wiping mechanism, a sealing outer bag, an arterial catheter connector sealing inner bag, a venous catheter connector sealing inner bag, a strip-shaped elastic head cover and ear covers;

[0007] The outer shell includes a left outer shell and a right outer shell that interlock with each other. A partition is horizontally arranged inside the outer shell. An upper cavity is formed inside the outer shell and above the partition. Disinfection wiping mechanisms are arranged inside the outer shell and below the partition, near the front and near the rear. Openings are formed on the left side near the middle and the right side near the middle and above the partition. Insertion holes for inserting catheter connectors are provided on the partition, one in front and one behind.

[0008] The outer sealing bag is placed in the upper cavity of the outer shell. The inner sealing bag for the arterial catheter connector and the inner sealing bag for the venous catheter connector are arranged one in front of the other inside the outer sealing bag. Both the inner sealing bag for the arterial catheter connector and the inner sealing bag for the venous catheter connector are provided with sterile cotton sleeves with their openings facing downwards. A heparin cap with its opening facing downwards is placed on the top of the sterile cotton sleeve. The bottom of the inner sealing bag for the arterial catheter connector and the outer sealing bag forms an arterial catheter connector sleeve that can be fitted onto the top of the first insertion hole on the partition. The bottom of the inner sealing bag for the venous catheter connector and the outer sealing bag forms a venous catheter connector sleeve that can be fitted onto the top of the second insertion hole on the partition.

[0009] The disinfection wiping mechanism includes a rotating sleeve, a rotating annular tube, a pressure rod, and a spring. The rotating sleeve is located in the middle of the rotating annular tube. The rotating sleeve is an inner conical sleeve with a smaller upper end and a larger lower end, consisting of two conical plates. An elastic squeezing plate is provided on the inner side of the conical plate. Elastic scrapers that slide and engage with the threaded grooves on the conduit connector are evenly distributed along the spiral direction on the inner side of the elastic squeezing plate. The rotating annular tube consists of two rotating annular tube sections, each with a pressure rod. The pressure rod passes horizontally through the corresponding rotating annular tube section and slides and engages with it. One end of the pressure rod is fixedly connected to the conical plate on the corresponding side. An annular baffle is provided on the pressure rod and inside the corresponding rotating annular tube. The spring is sleeved on the pressure rod. One end of the spring presses against the inner wall of the corresponding rotating annular tube section away from the rotating sleeve, and the other end presses against the annular baffle.

[0010] The bottom of the outer shell is provided with guide holes corresponding to the lower positions of the rotating sleeves on the front and rear sides. The top of the rotating sleeves on the front and rear sides corresponds one-to-one with the two insertion holes on the front and rear sides. One end of the strip-shaped elastic head cover is connected to one side of the ear cover, and the other end of the strip-shaped elastic head cover is connected to the other side of the ear cover. An operation hole is provided on the side of the strip-shaped elastic head cover near the ear cover. The exposed left side of the sealed outer bag is connected to the two sides of the operation hole of the strip-shaped elastic head cover near both ends.

[0011] As a preferred embodiment of the present invention, a disinfectant cotton pad is provided on the inner side of the elastic extrusion plate, and the elastic scraper extends out of the outer surface of the disinfectant cotton pad.

[0012] In a preferred embodiment of the present invention, a pouch opening ring is provided on the partition plate and at the top of both the front and rear insertion holes. The arterial catheter connector sleeve is fitted onto the front pouch opening ring and is sealed to the outer side wall of the front pouch opening ring. The venous catheter connector sleeve is fitted onto the rear pouch opening ring and is sealed to the outer side wall of the rear pouch opening ring.

[0013] As a preferred embodiment of the present invention, the top of the rotating annular tube is provided with an annular slide rail along the circumferential direction, and the bottom of the partition and above the rotating annular tube is provided with an annular groove. The top of the annular slide rail is embedded in the annular groove and slides in cooperation with the corresponding annular groove.

[0014] As a preferred embodiment of the present invention, the guide hole, rotating sleeve, insertion hole, sterile cotton sleeve and heparin cap on the same side are arranged coaxially.

[0015] In a preferred embodiment of the present invention, the exposed surface of the sealed outer bag near the edge of the outer shell forms a sealing fit with the outer shell.

[0016] As a preferred embodiment of the present invention, adhesive strips I are provided on the exposed left side of the sealed outer bag near both the front and rear sides, and adhesive strips II are provided on both sides of the strip-shaped elastic head sleeve located at the operation hole. The two adhesive strips I on the left side of the sealed outer bag are bonded to the adhesive strips II on both sides of the operation hole in a one-to-one correspondence.

[0017] As a preferred embodiment of the present invention, fastening components are provided on the front and rear sides of both the left and right outer shells, and the left and right outer shells are fastened together by the fastening components.

[0018] As a preferred embodiment of the present invention, the cross-section of the bag opening ring is shaped like the number 7.

[0019] As a preferred embodiment of the present invention, the heparin cap inside the disinfectant cotton cover is rotatably fitted with the top of the disinfectant cotton cover.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. When inserting the arteriovenous catheter connector into the guide hole, the threaded end of the connector first contacts the sterile cotton pad and is wiped clean. As insertion progresses, the threaded groove of the connector contacts the elastic scraper on the elastic compression plate. The front end of the connector squeezes the elastic compression plate and the sterile cotton pad, causing the sterilization wiping mechanism to rotate. During the advancement of the connector, the elastic scraper slides within the threaded groove at the front end, scraping away dirt (such as blood clots) as it slides. This achieves automatic wiping and sterilization of the front end of the connector and removal of blood clots and other dirt during insertion, reducing the connector's exposure to the outside environment, lowering the chance of contamination, reducing the workload of medical staff, and avoiding contamination caused by manual operation.

[0022] 2. After the arteriovenous catheter connector is inserted into the outer casing through the guide hole, the surface of the arteriovenous catheter connector is wiped and disinfected with a sterile cotton pad. The elastic scraper slides to remove dirt from the threaded groove. After cleaning and disinfecting, the arteriovenous catheter connector is pushed into the sterile cotton sleeve. Then, the heparin cap is screwed onto the threaded end of the arteriovenous catheter connector. After removing the left and right outer casings, the arterial catheter connector sleeve is tightly fitted onto the dialysis arterial catheter near the arterial catheter connector, and the venous catheter connector sleeve is tightly fitted onto the dialysis venous catheter near the venous catheter connector. This ensures that the disinfected arteriovenous catheter connector is completely sealed within the sterile cotton sleeve. The entire operation is completed in a completely closed and sterile state, preventing the arteriovenous catheter connector from coming into contact with the outside world during the entire process of descaling, wiping and disinfection, and putting on the heparin cap, thus avoiding contamination.

[0023] 3. Place the elastic headgear on the dialysis patient's head, and the ear covers on the ears. The sterilized and wrapped arteriovenous catheter connectors are then hung behind the patient's ears. Because the elastic headgear restrains the ear covers on the ears, it effectively prevents the ear covers from falling off the dialysis patient's ears. Attached Figure Description

Detailed Implementation

[0035] The present invention will now be described in detail with reference to the embodiments and accompanying drawings.

[0036] like Figures 1-4 As shown, the internal jugular vein dialysis catheter connector disinfection and sealing device includes an outer shell 1, a disinfection wiping mechanism 2, a sealing outer bag 3, an arterial catheter connector sealing inner bag 4, a venous catheter connector sealing inner bag 5, a strip-shaped elastic head cover 6, and an ear cover 7.

[0037] The outer casing 1 includes a left outer casing 11 and a right outer casing 12 that interlock, as shown below. Figure 2 and Figure 3As shown, fastening components 16 are provided on the front and rear sides of the left outer shell 11 and the right outer shell 12. The left outer shell 11 and the right outer shell 12 are fastened together by the fastening components 16. For example, a set of connecting plates is provided on the front and rear sides of the left outer shell 11 and the right outer shell 12 respectively. One connecting plate in the same set is provided with an elastic buckle, and the other connecting plate in the same set is provided with a corresponding groove. When the left outer shell 11 and the right outer shell 12 are fastened together, the elastic buckles in the two sets are simply fastened into the corresponding grooves. When the left outer shell 11 and the right outer shell 12 are disassembled, the elastic buckles in the two sets are simply pulled out from the corresponding grooves. A partition 13 is provided horizontally inside the outer shell 1. The partition 13 is composed of a left partition and a right partition. After the left outer shell 11 and the right outer shell 12 are fastened together, a sealing fit can be formed between the left partition and the right partition. An upper cavity 14 is formed inside the outer shell 1 and above the partition 13. Figure 3 As shown, disinfection wiping mechanisms 2 are provided inside the outer casing 1, below the partition 13, near the front and near the rear. Figure 4 As shown. The left side and right side of the outer casing 1 near the center and above the partition 13 are both open. The partition 13 has insertion holes 131 at the front and back for inserting conduit connectors.

[0038] The sealed outer bag 3 is placed inside the upper cavity 14 of the outer shell 1. The left outer shell 11 and the right outer shell 12 hold the front and rear sides of the sealed outer bag 3. The exposed surface of the sealed outer bag 3 near the edge of the outer shell 1 forms a sealing fit with the outer shell 1. A sealing strip can be used to form a sealing fit between the exposed surface of the sealed outer bag 3 near the edge of the outer shell 1 and the edge of the outer shell 1 near the exposed surface of the sealed outer bag 3. A sealing layer can also be provided on the fastening surface between the left outer shell 11 and the right outer shell 12, so that the inside of the outer shell 1 is in a sterile and sealed state. When using this internal jugular vein dialysis catheter connector disinfection and sealing device, the sealing strip can be torn off. The arterial catheter connector sealing inner bag 4 and the venous catheter connector sealing inner bag 5 are set one in front of the other inside the sealed outer bag 3. Both the arterial catheter connector sealing inner bag 4 and the venous catheter connector sealing inner bag 5 are provided with a sterile cotton sleeve 8. The opening of the sterile cotton sleeve 8 is facing downward. The top of the sterile cotton sleeve 8 is placed with the opening facing downward. The heparin cap 9 inside the sterile cotton sleeve 8 and the top of the sterile cotton sleeve 8 can be rotated to achieve independent rotation of the heparin cap 9. The bottom of the inner sealing bag 4 and the outer sealing bag 3 of the arterial catheter connector forms an arterial catheter connector sleeve 31 that can be fitted onto the top of the first insertion hole 131 on the partition 13. The bottom of the inner sealing bag 5 and the outer sealing bag 3 of the venous catheter connector forms a venous catheter connector sleeve 32 that can be fitted onto the top of the second insertion hole 131 on the partition 13. Figure 4 As shown, both the arterial catheter connector sleeve 31 and the venous catheter connector sleeve 32 are elastic sleeves.

[0039] The disinfection wiping mechanism 2 includes a rotating sleeve 21, a rotating annular tube 22, a pressure rod 23, and a spring 24, such as Figure 5As shown. The rotating sleeve 21 is located in the middle of the rotating annular tube 22. The rotating sleeve 21 is an inner conical sleeve composed of two conical plates, one on the left and one on the right, with a smaller upper end and a larger lower end. An elastic compression plate 25 is provided on the inner side of the conical plates. Elastic scrapers 26, which slide and engage with the threaded grooves on the conduit connector, are evenly distributed along the spiral direction on the inner surface of the elastic compression plate 25. Figure 6 As shown, a disinfectant cotton pad 28 is provided on the inner side of the elastic compression plate 25, and an elastic scraper 26 extends out of the outer surface of the disinfectant cotton pad 28. The rotating annular tube 22 is composed of two rotating annular tubes, left and right. Each of the left and right rotating annular tubes is provided with a pressure rod 23. The pressure rod 23 passes horizontally through the corresponding rotating annular tube and slides with the rotating annular tube. One end of the pressure rod 23 is fixedly connected to the conical plate on the corresponding side. An annular baffle 27 is provided on the outer wall of the pressure rod 23 and inside the corresponding rotating annular tube. A spring 24 is sleeved on the pressure rod 23. One end of the spring 24 presses against the inner wall of the corresponding rotating annular tube on the side away from the rotating sleeve 21, and the other end of the spring 24 presses against the annular baffle 27. Guide holes 15 are provided at the bottom of the outer shell 1 and below the rotating sleeves 21 on the front and rear sides. The tops of the rotating sleeves 21 on the front and rear sides correspond one-to-one with the two insertion holes 131 on the front and rear sides, as shown. Figure 4 and Figure 5 As shown. A sealing membrane can be provided at the bottom port of the guide hole 15 to seal the inside of the guide hole 15, thereby ensuring that the inside of the outer shell 1 is in a sterile and sealed state. The guide hole 15, rotating sleeve 21, insertion hole 131, sterile cotton sleeve 8 and heparin cap 9 on the same side are arranged coaxially.

[0040] On the partition 13, at the top of both the front and rear insertion holes 131, there are bag opening rings 132. Each bag opening ring 132 consists of a left bag opening ring and a right bag opening ring. The cross-section of the bag opening ring 132 is shaped like the number 7. Figure 5 As shown. The arterial catheter connector sleeve 31 is fitted onto the anterior pouch opening ring 132 and seals against the outer wall of the anterior pouch opening ring 132. The venous catheter connector sleeve 32 is fitted onto the posterior pouch opening ring 132 and seals against the outer wall of the posterior pouch opening ring 132. Figure 4 and Figure 7 As shown. An annular slide rail 29 is provided at the top of the rotating annular tube 22 along the circumferential direction. The annular slide rail 29 consists of a left annular slide rail and a right annular slide rail. An annular groove 133 is provided at the bottom of the partition plate 13 and above the rotating annular tube 22, as shown. Figure 7 As shown, the top of the annular slide rail 29 is embedded in the annular slide groove 133 and slides in cooperation with the corresponding annular slide groove 133.

[0041] One end of the strip-shaped elastic headband 6 is connected to one side of the earmuff 7, and the other end of the strip-shaped elastic headband 6 is connected to the other side of the earmuff 7, as shown below. Figure 1 and Figure 8 As shown, the strip-shaped elastic headgear 6 has an operation hole 61 on the side near the ear sleeve 7. In this embodiment, the operation hole 61 is located on the rear side of the ear sleeve 7. The exposed left side of the sealed outer bag 3 is connected to the two sides of the operation hole 61 of the strip-shaped elastic headgear 6 near both ends. In this embodiment, adhesive strips I 33 are provided on the exposed left side of the sealed outer bag 3 near both the front and rear sides. Adhesive strips II 62 are provided on the strip-shaped elastic headgear 6 on both sides of the operation hole 61. The two adhesive strips I 33 on the left side of the sealed outer bag 3 are bonded to the adhesive strips II 62 on both sides of the operation hole 61 in a one-to-one correspondence.

[0042] In this embodiment, both the outer shell 1 and the partition 13 are made of transparent material. Transparent doors 110 are provided on the left outer shell 11 and right outer shell 12 corresponding to the disinfection wiping mechanism 2. When closed, the two doors 110 on the left outer shell 11 are sealed to the left outer shell 11, and the two doors 110 on the right outer shell 12 are sealed to the right outer shell 12. When it is necessary to open the left outer shell 11 and right outer shell 12, the position of the disinfection wiping mechanism 2 can be viewed through the transparent outer shell 1 and partition 13. The doors 110 on either the left or right outer shell 11 are opened, and the disinfection wiping mechanism 2 is rotated at a certain angle using a finger, so that the left rotating annular tube is located inside the left outer shell 11, and the corresponding right rotating annular tube is located inside the right outer shell 12. Thus, when opening the left or right outer shell 11, the disinfection wiping mechanism 2 will not affect the opening of the left or right outer shell 12.

[0043] All components of this internal jugular vein dialysis catheter connector disinfection, sealing, and fixation device are assembled in a sterile room. After assembly, the outer shell 1 is in a sterile and sealed state. When using this internal jugular vein dialysis catheter connector disinfection, sealing, and fixation device, the following steps can be followed:

[0044] S1. Remove the sealing film on the bottom port of the guide hole 15 on the front side, and insert the arterial catheter connector 101 into the guide hole 15 on the front side. During the insertion process, the threaded end of the arterial catheter connector 101 first contacts the sterile cotton pad 28 and wipes its surface. As the insertion progresses, the threaded groove at the front end of the arterial catheter connector 101 contacts the elastic scraper 26 on the elastic compression plate 25. The front end of the arterial catheter connector 101 squeezes the elastic compression plate 25 and the sterile cotton pad 28. The elastic compression plates 25 on the left and right sides push the corresponding left and right conical plates away from each other. Then the pressure rods on the left and right sides... 23 are separated from each other, the springs 24 on the left and right sides are compressed, the disinfection wiping mechanism 2 rotates accordingly, and the annular slide rail 29 slides in the annular slide groove 133; at the same time, during the advancement of the arterial catheter connector 101, the elastic scraper 26 slides in the threaded groove at the front end of the arterial catheter connector 101, and scrapes off the dirt (such as blood scabs) in the threaded groove while sliding. Multiple elastic scrapers 26 are provided, which can scrape off the dirt in the threaded groove at the front end of the arterial catheter connector 101 multiple times, thereby realizing the automatic wiping and disinfection of the front end of the arterial catheter connector 101 and scraping off the dirt such as blood scabs during the insertion process.

[0045] S2. Tear off the sealing film on the bottom port of the guide hole 15 on the rear side, insert the venous catheter connector 102 into the guide hole 15 on the rear side, wipe and disinfect the venous catheter connector 102 in the same way, and scrape off blood scabs and other dirt in the threaded groove, so that the venous catheter connector 102 can automatically wipe and disinfect the front end of the venous catheter connector 102 and scrape off blood scabs and other dirt during the insertion process.

[0046] S3. Continue pushing the arterial catheter connector 101 and the venous catheter connector 102 into the outer shell 1. The front end of the arterial catheter connector 101 passes through the insertion hole 131 on the front side and is inserted into the sterile cotton sleeve 8 inside the inner sealing bag 4 of the arterial catheter connector. Hold the dialysis arterial catheter 103 with one hand and continue pushing it into the outer shell 1, so that the front end of the arterial catheter connector 101 extends into the heparin cap 9 on the front side. Press down on the left and right exposed parts of the outer sealing bag 3 corresponding to the inner sealing bag 4 of the arterial catheter connector with the other hand. When applying pressure, rotate the heparin cap 9 on the front side once in the same direction of rotation, then release it, and continue to rotate the heparin cap 9 on the front side once in the same direction of rotation until the heparin cap 9 is completely screwed onto the thread at the front end of the arterial catheter connector 101, and the arterial catheter connector 101 is fully inserted into the arterial catheter connector. The venous catheter connector 102 is inserted into the sterile cotton sleeve 8 inside the inner sealed bag 4. The tip of the venous catheter connector 102 passes through the rear insertion hole 131 and is inserted into the sterile cotton sleeve 8 inside the inner sealed bag 5. One hand holds the dialysis venous catheter 104 and continues to push it into the outer shell 1, so that the tip of the venous catheter connector 102 extends into the rear heparin cap 9. The other hand presses down on the left and right exposed parts of the corresponding outer sealed bag 3 of the inner sealed bag 5, applying pressure and rotating the rear heparin cap 9 once in the same direction, then releasing it, and continuing to rotate the rear heparin cap 9 once in the same direction until the rear heparin cap 9 is completely screwed onto the threads at the tip of the venous catheter connector 102, and the venous catheter connector 102 is completely inserted into the sterile cotton sleeve 8 inside the inner sealed bag 5. This ensures that the heparin cap 9 is completely sealed and sterile before being screwed onto the arterial catheter connector 101 and the venous catheter connector 102.

[0047] S4. Disassemble the two sets of fastening components 16 of the left outer shell 11 and the right outer shell 12, so that the left outer shell 11 and the right outer shell 12 are separated from the sealed outer bag 3. The arterial catheter connector sleeve 31 slides out from the front bag opening opening ring 132 and is put on the dialysis arterial catheter 103 near the arterial catheter connector 101, so that the sterilized arterial catheter connector 101 is completely sealed in the sterile cotton sleeve 8 in the sterile arterial catheter connector sealed inner bag 4. The venous catheter connector sleeve 32 slides out from the rear bag opening opening ring 132 and is put on the dialysis venous catheter 104 near the venous catheter connector 102, so that the sterilized venous catheter connector 102 is completely sealed in the sterile cotton sleeve 8 in the sterile venous catheter connector sealed inner bag 5.

[0048] S5. The unfolded strip elastic headgear 6 is placed on the head of the dialysis patient, and the ear covers 7 are placed on the ears. This allows the arterial catheter connector 101 and venous catheter connector 102, which have been disinfected and wrapped after hemodialysis, to be attached to the back of the patient's ears. Because the strip elastic headgear 6 placed on the head of the dialysis patient has a pulling effect on the ear covers 7, it effectively prevents the ear covers 7 from falling off the dialysis patient's ears.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
