Description

Technical Field

[0001] The present application relates to the technical field of peritoneal dialysis tunnel flushing, and in particular to a subcutaneous tunnel flusher for peritoneal dialysis. Background Art

[0002] Peritoneal dialysis is an effective renal replacement therapy for end-stage renal disease, and the peritoneal dialysis catheter is the "lifeline" of peritoneal dialysis patients. The tunnel opening is the exit of the channel where the peritoneal dialysis catheter goes from the outside of the peritoneum through the muscle and subcutaneous tissue to the skin. If not treated in time, it will develop into a tunnel infection.

[0003] When peritoneal dialysis patients develop subcutaneous tunnel and outlet infections, it can lead to severe abdominal infection or forced catheter removal. The outlet will be red, swollen, hot, painful, and accompanied by purulent secretions. The skin at the tunnel entrance will bulge with hard abscesses, and the patient will experience pain or tenderness. Therefore, when treating infections in the subcutaneous tunnel and outlet of peritoneal dialysis patients, surgical incision and abscess drainage and clinical conservative treatment (i.e., daily dressing changes) are usually used. Since the tunnel inflammation lesions are deep in the skin, it is difficult for general disinfection and dressing changes to directly reach the lesions. Systemic medication treatment takes a long time and is not convenient to use. Therefore, it is necessary to use a syringe to inject disinfectant and saline to flush the subcutaneous tunnel.

[0004] When using existing syringes with needles for flushing, there is a risk of damaging the peritoneal dialysis catheter. When the syringe needle is removed and used, due to the short and thick nipple of the syringe, it can only flush the edge of the catheter outlet, but cannot disinfect bacteria, exudate, purulent secretions and infection foci outside the catheter tunnel, resulting in incomplete disinfection and affecting the treatment effect. Utility Model Content

[0005] In order to achieve the purpose of disinfecting the catheter tunnel, i.e., the skin at the exit, after the disinfectant is sucked out by the syringe, thereby clearing the purulent secretions and removing the dead flesh, so that the medicine can directly reach the deep of the lesion and thus carry out effective treatment, the present application provides a subcutaneous tunnel flusher for peritoneal dialysis.

[0006] The present application provides a subcutaneous tunnel flusher for peritoneal dialysis, which adopts the following technical solution:

[0007] A subcutaneous tunnel irrigator for peritoneal dialysis comprises a syringe, wherein the syringe is detachably connected to a irrigating component, the irrigating component comprises a connector for connecting the syringe, a hose fixedly connected to the connector, and a irrigating head fixedly connected to the hose, the irrigating head and the connector are respectively located at two ends of the hose, the irrigating head is provided with a irrigating hole, and the irrigating hole, the hose and the syringe are connected.

[0008] By adopting the above technical solution, when in use, the medical staff first uses a syringe to draw up the disinfectant, and then connects the hose to the syringe through a connector, and then extends the flushing head along the peritoneal dialysis catheter into the patient's subcutaneous tunnel opening. After the flushing head is aligned with the part that needs to be flushed, the disinfectant can be injected into the flushing head by pressing the syringe, and finally sprayed out from the flushing hole, thereby achieving disinfection of the patient's catheter tunnel opening skin. The use is simple and convenient, and avoids the situation in the prior art where the needle tip is relatively sharp and causes damage to the catheter.

[0009] Preferably, the syringe includes a syringe, a piston sliding in the syringe, a connecting shaft fixedly connected to the piston, a pressing handle fixedly connected to the end of the connecting shaft away from the piston, and a connecting nipple integrally formed on the syringe, the connecting nipple is connected to the inner cavity of the syringe, and the connector is installed on the connecting nipple.

[0010] By adopting the above technical solution, the disinfectant is sucked into the syringe through the connecting nipple during use, and then the connecting nipple and the joint are connected, and the injection of the disinfectant can be achieved by driving the piston to move by pressing the handle, which is simple and convenient to use.

[0011] Preferably, the outer side wall of the syringe is provided with scale lines.

[0012] By adopting the above technical solution, the injection status of the disinfectant in the syringe can be observed through the scale line during use, so that it is convenient for medical staff to control the injection amount of the disinfectant.

[0013] Preferably, the connector comprises a connecting portion and a rotating portion, the connecting portion is detachably connected to the connecting nipple, the rotating portion is rotatably connected to the connecting portion, and the hose is connected to the rotating portion.

[0014] By adopting the above technical solution, when in use, the hose is connected to the syringe through the connecting part, and the rotating part prevents the hose from rotating to cause the angle of the flushing head to change, thereby avoiding affecting the spraying position of the disinfectant.

[0015] Preferably, the outer side wall of the connecting portion is fixedly connected with a fixing wing.

[0016] By adopting the above technical solution, the fixing wings are provided during use, which makes it easy to take the connector and facilitates the connection between the connector and the connecting nipple on the syringe.

[0017] Preferably, the flushing head comprises a tube protection shell fixedly connected to the hose, the tube protection shell is provided with a tube protection groove for embedding a catheter, and the flushing hole is provided at one end of the tube protection shell away from the hose.

[0018] By adopting the above technical solution, when the flushing head is used to spray disinfectant on the subcutaneous tunnel opening, the catheter is embedded in the protective tube groove, that is, the flushing head is supported by the catheter. On the one hand, it guides the sliding of the flushing head, avoiding the problem in the prior art that the catheter is easily damaged when the needle is sharp and inserted into the tunnel. On the other hand, it avoids the shaking of the flushing head, which affects the disinfection efficiency.

[0019] Preferably, a buffer head is fixedly connected to the end of the protective tube shell.

[0020] By adopting the above technical solution, a buffer head is provided during use to prevent the flushing head from entering the patient's subcutaneous tunnel and causing secondary damage to the patient.

[0021] Preferably, a filter screen is provided in the flushing hole.

[0022] By adopting the above technical solution, a filter net is set up to filter the flushing hole during use, thereby preventing purulent secretions, exudate, etc. from flowing back into the flushing hole when the flushing head is inserted into the patient's subcutaneous tunnel, thereby causing blockage in the flushing hole and rendering the entire device unusable.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When in use, the hose is connected to the syringe through the connector. When the flushing head is inserted into the subcutaneous tunnel, the flushing head is supported and limited by the contact between the protective tube shell and the inner wall of the protective tube groove and the catheter. At the same time, the risk of damaging the catheter during the insertion of the tunnel when the flushing head in the prior art is relatively sharp is avoided. While ensuring effective treatment, it is more convenient to use;

[0025] 2. When in use, the fixed wing is provided to facilitate medical staff to take the connector, thereby facilitating the connection part to be connected to the connecting nipple of the syringe, making it more convenient to use. The rotating part and the connecting part are rotated together to avoid the flushing head from swinging when the twisting force of the hose is too large, and at the same time, it is convenient for medical staff to adjust the direction angle of the flushing head;

[0026] 3. When in use, a buffer head is set at the end of the protective tube shell to avoid secondary injury to the patient when the flushing head is inserted into the subcutaneous tunnel opening. A filter net is set in the flushing hole to prevent purulent secretions and exudate from the wound from flowing back into the flushing hole and causing blockage in the flushing hole, thereby ensuring normal use of the device.

The syringe 1 comprises a syringe 11, a piston 12, a connecting shaft 13, a pressing handle 14 and a connecting nipple 15. The syringe 11 is used to store the absorbed disinfectant. The piston 12 is slidably connected in the syringe 11. One end of the connecting shaft 13 is fixedly connected to the piston 12, and the other end is fixedly connected to the pressing handle 14. The pressing handle 14 is arranged outside the syringe 11. The connecting nipple 15 is integrally formed at one end of the syringe 11 away from the pressing handle 14, and the inner channel of the connecting nipple 15 is connected to the inner cavity of the syringe 11. A scale line 7 is integrally formed on the outer wall of the syringe 11. When in use, the disinfectant is sucked into the syringe 11 through the connecting nipple 15, and the piston 12 is driven to slide along the axial direction of the syringe 11 by pressing the pressing handle 14, so as to realize the spraying of the disinfectant. The medical staff ensures the spraying amount of the disinfectant by observing the scale line 7.

[0037] Reference Figure 1 and Figure 3The flushing part 2 includes a connector 3, a hose 4 and a flushing head 5. The connector 3 and the connecting nipple 15 on the syringe 1 are detachably connected, and the connecting nipple 15 and the connector 3 are interference fit. The hose 4 is fixedly connected to the connector 3, and the flushing head 5 is fixedly connected to the hose 4. The connector 3 and the flushing head 5 are respectively located at both ends of the hose 4. A flushing hole 6 is opened on the flushing head 5, and the flushing hole 6 is connected to the hose 4, and the hose 4 is connected to the connector 3. When in use, the hose 4 is connected to the syringe 1 through the connector 3, and the disinfectant is transported into the hose 4 through the syringe 1, and finally sprayed out from the flushing hole 6, and the length is increased through the hose 4, so that the flushing head 5 can disinfect and flush the subcutaneous tunnel.

[0038] Reference Figure 3 and Figure 4 The connector 3 includes a connecting portion 31 and a rotating portion 32, wherein the connecting portion 31 is used to plug in the connecting nipple 15, a fixed wing 8 is integrally formed on the outer wall of the connecting portion 31, the fixed wing 8 is flat, and friction patterns are formed on the fixed wing 8, the rotating portion 32 is rotatably connected to the connecting portion 31, and the rotating portion 32 is connected to the hose 4; when in use, the connecting portion 31 is plugged into the connecting nipple 15 by pinching the fixed wing 8, which is more convenient to take, and the angle of the hose 4 is adjusted by rotating the rotating portion 32, thereby avoiding the shaking of the flushing head 5 when the torque of the hose 4 is too large.

[0039] Reference Figure 5 and Figure 6 The flushing head 5 includes an arc-shaped protective tube shell 51. In the present embodiment, the overall length of the protective tube shell 51 is preferably 1 to 2 centimeters. One end of the protective tube shell 51 is fixedly connected to the hose 4, and the other end is a flushing end. The protective tube shell 51 is provided with an arc-shaped protective tube groove 52, and the flushing hole 6 is arranged at the flushing end. In order to increase the liquid discharge rate of the flushing hole 6, a plurality of flushing holes 6 are provided, and the plurality of flushing holes 6 are extruded and arranged at intervals along the circumference of the protective tube shell 51. In the present embodiment, 7 flushing holes 6 are provided, and each flushing hole 6 is provided with a filter screen 10. The flushing end of the protective tube shell 51 is fixedly connected with a buffer head 9. In the present embodiment, the buffer head 9 is preferably arranged as a flexible rubber block.

On the one hand, the flushing head 5 is supported, so as to facilitate the stability of the flushing hole 6 when flushing the tunnel; on the other hand, the protective tube shell 51 is overall arc-shaped, which avoids the situation in the prior art that the sharp part easily damages the catheter. By setting the buffer head 9, it is effectively avoided that the wound is caused to suffer secondary damage when the flushing head 5 partially extends into the subcutaneous tunnel. By setting the filter net 10, when the flushing head 5 partially extends into the subcutaneous tunnel, purulent secretions, exudate, etc. at the wound flow back into the flushing hole 6, thereby causing blockage in the flushing hole 6.

[0041] The implementation principle of the embodiment of the present application is as follows: when in use, the disinfectant is first sucked into the syringe 11 through the syringe 1, and then the hose 4 is connected to the connecting nipple 15 on the syringe 1 through the connector 3. After the connection is completed, according to the suppuration condition of the patient's exit tunnel, the flushing head 5 is appropriately partially extended into the subcutaneous tunnel, and at this time the catheter part is located in the protective tube groove 52, so that the flushing head 5 can be guided by the catheter, and the buffer head 9 is used in conjunction to avoid the flushing head 5 swinging to cause secondary injury to the patient. Thereafter, by pressing the pressing handle 14 on the syringe 1, the disinfectant enters the flushing head 5 along the hose 4 and is sprayed out from the flushing hole 6, thereby achieving disinfection of the subcutaneous tunnel. During the disinfection process, the filter net 10 is used to prevent purulent secretions, exudates, etc. from flowing back into the flushing hole 6, thereby avoiding the flushing hole 6 from being blocked and affecting the normal use of the device.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
