Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical equipment, and in particular to a peritoneal dialysis pipeline docking device capable of reducing infection risks. Background Art
[0002] The main user group of peritoneal dialysis is patients with chronic renal failure. It requires a catheter to be placed in the patient's abdomen. The catheter (peritoneal dialysis catheter) is inserted through a minimally invasive incision. The catheter will subsequently grow together with the wound and usually accompany the patient for the rest of his life. Therefore, preventing contamination of the catheter has become an important consideration in patients' daily lives.
[0003] In order to prevent infection, an iodine cap for sealing is provided at the end of the peritoneal dialysis tube. There is iodine on the inner wall of the iodine cap. When it is screwed on the end of the peritoneal dialysis tube, the end of the peritoneal dialysis tube can be disinfected. Usually, patients need to undergo four peritoneal dialysis sessions a day. The current situation is that a new iodine cap must be replaced after each dialysis. The unit price of the iodine cap is about 1.5 yuan, which will bring an economic burden of 200 yuan to the patient every month. Recycling a single iodine cap for multiple times has become a technical problem that needs to be solved. Summary of the invention
[0004] The present invention provides a peritoneal dialysis pipeline docking device with reduced infection risk. The structure has no consumable parts, thereby reducing the use cost and the operation difficulty.
[0005] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: A peritoneal dialysis pipeline docking device that reduces the risk of infection, comprising: a first connector, wherein one end of the first connector is provided with a first interface, and the other end is provided with a self-sealing plug, the outer wall of the self-sealing plug is provided with a first through hole connected to the first interface, the outside of the self-sealing plug is slidably matched with a self-sealing sleeve, and a first spring is provided between the self-sealing sleeve and the first interface; a second connector, one end of the second connector is provided with a second interface, and the other end is provided with a self-sealing slot adapted to the self-sealing plug, the inner side wall of the self-sealing slot is provided with a second through hole connected to the second interface, the self-sealing slot is matched with a self-sealing plug, and a second spring is provided between the self-sealing plug and the bottom of the self-sealing slot; a locking sleeve, the locking sleeve is sleeved on the outside of the second connector, and the outside of the first connector is provided with a locking pin matched with the locking sleeve.
[0006] Preferably, the first through holes are provided in plurality, and the distance between any two adjacent first through holes is smaller than the diameter.
[0007] Preferably, the second through holes are provided in plurality, and the number of the second through holes is one less than the first through hole, and the distance between any two adjacent second through holes is less than the diameter.
[0008] Preferably, a first sealing ring is provided on the inner wall of the self-sealing sleeve close to the free end; and a second sealing ring is provided on the outer wall of the self-sealing plug close to the free end.
[0009] Preferably, a third spring is provided between the locking sleeve and the second interface, and the locking sleeve is provided with a serpentine lock track corresponding to the locking pin.
[0010] The beneficial effects of the present invention are as follows: the first connector is connected to the catheter on the patient through the first interface, and the second connector is connected to the dialysis equipment through the second interface. When the patient needs dialysis, the medical staff immerses and disinfects the first connector and the second connector. At this time, the self-sealing sleeve and the self-sealing plug are respectively self-sealed to the first connector and the second connector, so that the disinfectant will not enter the catheter and the dialysis equipment. Then the self-sealing plug of the first connector is inserted into the self-sealing slot for connection. In this process, the second connector pushes the self-sealing sleeve through the self-sealing slot, and the self-sealing plug inserted into the self-sealing slot presses the self-sealing plug, so that the first through hole corresponds to the second through hole, and the first connector and the second connection form a conductive relationship, and the locking sleeve is firmly fixed and constrained by the cooperation with the locking pin, so as to ensure the smooth progress of dialysis. After the dialysis is completed, the medical staff contacts the locking sleeve. At this time, under the action of the first spring and the second spring, the self-sealing sleeve and the self-sealing plug are reset respectively, and the first connector and the second connector are separated, and the self-sealing blocking is completed. At this time, the first connector and the second connector can be immersed and disinfected. There are no consumable parts in this structure, so the use cost is reduced, and the difficulty of operation is also reduced. The first connector and the second connector can have a very beneficial conduction effect at all angles, thereby reducing the resistance to liquid flow and ensuring the dialysis effect. The first sealing ring and the second sealing ring improve the sealing effect of the self-sealing sleeve and the self-sealing plug, thereby further preventing the risk of infection.

[0016] according to Figure 1 , Figure 2 As shown, a peritoneal dialysis pipeline docking device for reducing the risk of infection comprises: a first connector 1, wherein the first connector 1 is provided with a first interface 2 at one end, and a self-sealing plug 3 at the other end, the outer wall of the self-sealing plug is provided with a first through hole 4 connected to the first interface 2, the self-sealing plug 3 is slidably matched with a self-sealing sleeve 5 on the outside, and a first spring 6 is provided between the self-sealing sleeve 5 and the first interface 2; a second connector 7, wherein the second connector 7 is provided with a second interface 8 at one end, and a self-sealing slot 9 matched with the self-sealing plug 3 at the other end, the inner wall of the self-sealing slot 9 is provided with a second through hole 10 connected to the second interface 8, the self-sealing plug 11 is matched in the self-sealing slot 9, and a second spring 12 is provided between the self-sealing plug 11 and the bottom of the self-sealing slot 9; a locking sleeve 13, wherein the locking sleeve 13 is sleeved on the outside of the second connector 7, and the first connector 1 is provided with a locking pin 14 matched with the locking sleeve 13 on the outside.
[0017] In the above arrangement, the first connector 1 is connected to the catheter on the patient through the first interface 2, and the second connector 7 is connected to the dialysis equipment through the second interface 8. When the patient needs dialysis, the medical staff immerses and disinfects the first connector 1 and the second connector 7. At this time, the self-sealing sleeve 5 and the self-sealing plug 11 respectively seal the first connector 1 and the second connector 7, so that the disinfectant will not enter the catheter and the dialysis equipment. Then the self-sealing plug 3 of the first connector 1 is inserted into the self-sealing slot 9 for connection. During this process, the second connector 7 pushes open the self-sealing sleeve 5 through the self-sealing slot, and the self-sealing plug 3 inserted into the self-sealing slot 9 presses the self-sealing plug 11, so that the first through hole 4 corresponds to the second through hole 10, so that the first connector 1 and the second connection form a conductive relationship, and the locking sleeve 13 firmly fixes and constrains the first connector 1 and the second connector 7 through cooperation with the locking pin 14, thereby ensuring the smooth progress of dialysis. After completing dialysis, the medical staff contacts the locking sleeve 13. At this time, under the action of the first spring 6 and the second spring 12, the self-sealing sleeve 5 and the self-sealing plug 11 are reset respectively, and the first connector 1 and the second connector 7 are separated, and the self-sealing blocking is completed. At this time, the first connector 1 and the second connector 7 can be immersed and disinfected. This structure does not have consumable parts, thereby reducing the cost of use and the difficulty of operation.
[0018] The first through holes 4 are provided in plurality, and the distance between any two adjacent first through holes 4 is smaller than the diameter. The second through holes 10 are provided in plurality, and the number is one less than the first through hole 4, and the distance between any two adjacent second through holes 10 is smaller than the diameter.
[0019] Through this arrangement, it is ensured that the first connector 1 and the second connector 7 can have a very beneficial conduction effect at all angles, thereby reducing the liquid flow resistance and ensuring the dialysis effect.
[0020] A first sealing ring 15 is disposed on the inner wall of the self-sealing sleeve 5 close to the free end; a second sealing ring 16 is disposed on the outer wall of the self-sealing plug 11 close to the free end.
[0021] The first sealing ring 15 and the second sealing ring 16 improve the sealing effect between the self-sealing sleeve 5 and the self-sealing plug 11, thereby further preventing the risk of infection.
[0022] A third spring 18 is disposed between the locking sleeve 13 and the second interface 8 , and a serpentine locking track 17 is disposed on the locking sleeve 13 corresponding to the locking pin 14 .
[0023] This structure reduces the difficulty of operating the lock sleeve 13 and improves the locking effect.
