Description

Technical Field

[0001] The present invention belongs to the technical field related to medical care devices, and more specifically, particularly relates to a peritoneal dialysis pipeline end connection protective sleeve. Background Art

[0002] The human peritoneum is a very good biological semipermeable membrane with excellent diffusion, permeation, secretion and absorption functions. Therefore, when facing severe edema, water intoxication and heart failure caused by acute renal failure, chronic renal failure or acute drug poisoning, peritoneal dialysis treatment is usually used to excrete harmful substances such as urea, creatinine, uric acid, carbonates, etc. produced by metabolism in the body.

[0003] During peritoneal dialysis treatment, a small tube is implanted in the patient's abdomen to introduce dialysate into the abdominal cavity. After a period of time, the dialysate containing harmful substances is discharged. Whether it is the introduction or the discharge of dialysate, the dialysis bag and the abdominal cavity need to be connected through a hose, that is, the abdominal implant tube and the dialysis bag are connected through a connector (for bag replacement).

[0004] For peritoneal dialysis patients, dialysis treatment is a long-term process. During daily dialysis treatment, the dialysis bag needs to be repeatedly plugged in and out several times (once for dialysate introduction, once for dialysate discharge and bag change, and the dialysis cycle needs to be repeated several times a day). This will not only cause the joints to loosen, but each plugging and unplugging will also increase the risk of infection. In addition, most peritoneal dialysis patients receive peritoneal dialysis treatment at home. Due to the lack of professional supervision from medical staff, peritoneal dialysis patients will move freely during the dialysis process, which will also cause the joints to disconnect, resulting in dialysis failure and even increasing the risk of dialysis contamination. Summary of the invention

[0028] Please refer to Figure 1 and Figure 2 ,in, Figure 1 A schematic diagram of the structure of a peritoneal dialysis tubing end connection protective cover in an open state in one embodiment of the present invention; Figure 2 The present invention is a simplified schematic diagram of the structure of a peritoneal dialysis tubing end connection protective sleeve in a closed state in one embodiment of the present invention.

[0029] The present invention provides a peritoneal dialysis tubing end connection protective sleeve, which is used to "wrap" the peritoneal dialysis tubing end during peritoneal dialysis treatment, thereby achieving structural protection of the peritoneal dialysis tubing end and also achieving a sterilization function. The peritoneal dialysis tubing end in the present invention refers to a connector structure set at any position on the peritoneal dialysis tubing.

[0030] In the present invention, the peritoneal dialysis tubing end connection protective sleeve mainly includes two parts, namely, the protective sleeve outer shell and the content. The protective sleeve outer shell is an empty shell structure, which is made of medical grade hard materials. For example, 314 medical grade stainless steel, or a polymer material with certain antibacterial function (the outer side of the PVC shell is sprayed with silver ion coating). The content has certain elasticity and water absorption. The elasticity is to ensure that the content can be slightly deformed according to the outer contour shape of the peritoneal dialysis tubing when it contacts and is under pressure with the peritoneal dialysis tubing, so as to completely wrap the peritoneal dialysis tubing.

[0031] Specifically, the protective cover outer shell includes an openable and closable upper shell 1 and a lower shell 2. The upper shell 1 and the lower shell 2 have basically the same structure. When the upper shell 1 and the lower shell 2 are snapped together and closed, they can form a rectangular shell structure (i.e., the protective cover outer shell). The upper shell 1 and the lower shell 2 can also be separated and opened.

[0032] In one embodiment of the present invention, the upper shell 1 and the lower shell 2 are connected in a hinged manner. The upper shell 1 and the lower shell 2 are hinged and a lock 3 is provided on one side of the upper shell 1 and the lower shell 2. Specifically, a hinge is provided on the long side of the shell. The hinge can be an additional structure or an existing structure of the protective cover outer shell. When the upper shell 1 and the lower shell 2 are made of polymer materials, the long side connecting the upper shell 1 and the lower shell 2 is not cut off (such as Figure 1 As shown in the figure, the retained structure (the existing structure of the protective cover outer shell) can replace the hinge to realize the hinge connection between the upper shell 1 and the lower shell 2. In this embodiment, the protective cover outer shell has a simple structure and a low manufacturing cost, and is suitable for one-time use or a small number of repeated uses (for example, 4-8 times of repeated use). When the upper shell 1 and the lower shell 2 are made of metal materials, the upper shell 1 and the lower shell 2 are additionally provided with a hinge assembly at the hinge position. In this structural form, although the structure of the protective cover outer shell becomes complicated, the protective cover outer shell and the hinge assembly are highly durable and can be reused many times.

[0033] A lock 3 is provided on the outer shell of the protective cover for locking the outer shell of the protective cover after the upper shell 1 and the lower shell 2 are closed. Specifically, the lock 3 is a buckle structure, which can achieve reliable closure of the upper shell 1 and the lower shell 2 and facilitate opening between the upper shell 1 and the lower shell 2. The present invention does not limit the specific structure of the buckle structure, and any structure that can achieve the closure and locking of the upper shell 1 and the lower shell 2 can be applied to the present invention.

[0034] After the upper shell 1 and the lower shell 2 are snapped and locked, in order to allow the pipeline to extend, the present invention optimizes the upper shell 1 and the lower shell 2 as follows, and provides an avoidance space for the pipeline to extend by setting a half-hole structure. Specifically, one end of the upper shell 1 is provided with an upper shell 1 inlet half-hole, and the other end of the upper shell 1 is provided with an upper shell 1 outlet half-hole; one end of the lower shell 2 is provided with a lower shell 2 inlet half-hole corresponding to the upper shell 1 inlet half-hole, and the other end of the lower shell 2 is provided with a lower shell 2 outlet half-hole corresponding to the upper shell 1 outlet half-hole; after the upper shell 1 and the lower shell 2 are closed, the upper shell 1 inlet half-hole and the lower shell 2 inlet half-hole form a circular hole-shaped inlet, and the upper shell 1 outlet half-hole and the lower shell 2 outlet half-hole form a circular hole-shaped outlet, and the inlet and outlet are used to be stuck on the peritoneal dialysis pipeline end. Furthermore, in the present invention, a half-hole protective layer 4 is provided on the inlet half-hole of the upper shell 1, the outlet half-hole of the upper shell 1, the inlet half-hole of the lower shell 2, and the outlet half-hole of the lower shell 2. The half-hole protective layer 4 is made of medical silicone material. The half-hole protective layer 4 has high flexibility and can improve the airtightness at the hole mouth while not affecting the flow of liquid inside the pipeline.

[0035] In a specific embodiment of the present invention, the outer shell of the protective cover formed by the upper shell 1 and the lower shell 2 being buckled and locked is a cylindrical structure, and circular hole structures (i.e., the above-mentioned inlet and outlet) are provided at both axial ends of the outer shell of the protective cover. In other embodiments of the present invention, the outer shell of the protective cover can also adopt other shapes, such as a rectangular parallelepiped structure, a regular polygonal prism structure, etc., and can also be designed as a cartoon shape, etc., under the premise of taking into account practicality, so that it has a higher aesthetics.

[0036] As for the contents, the contents are made of a material that can absorb disinfection liquid, and the contents are elastic materials. The contents are arranged on the upper shell 1 and the lower shell 2, and are used to wrap the peritoneal dialysis line end after the upper shell 1 and the lower shell 2 are closed. The contents include the contents of the upper shell 1 and the contents of the lower shell 2, the contents of the upper shell 1 are arranged on the upper shell 1, and the contents of the lower shell 2 are arranged on the lower shell 2; the contents of the upper shell 1 are provided with a first receiving groove that matches the shape of the peritoneal dialysis line end, and the contents of the lower shell 2 are provided with a second receiving groove that matches the shape of the peritoneal dialysis line end. Specifically, the contents are iodine cotton, and further, a layer of water-permeable seamless cloth or similar materials can be arranged on the surface of the contents to improve the friction resistance of the surface of the contents, and at the same time, materials such as cotton wool can be prevented from adhering to the peritoneal dialysis line end.

[0037] In one embodiment of the present invention, a positioning hole is provided on the content, and a positioning column cooperating with the positioning hole is provided on the upper shell 1 and the lower shell 2. This not only can position the installation of the contents, but also can improve the firmness of the contents on the upper shell 1 and the lower shell 2.

[0038] In addition, the contents are detachably connected to the upper shell 1 and the lower shell 2. In the present invention, both the upper shell 1 and the lower shell 2 are provided with a mounting groove structure, and claws (which can be understood as small protrusions integrally formed with the upper shell 1 and the lower shell 2) are provided at the edges of the grooves of the mounting grooves, and a card plate is fixedly provided on the contents, and the card plate provided on the contents can be installed in the mounting groove and fixed by the claws.

[0039] It should be noted that the present invention does not limit the specific size of the outer shell of the protective sleeve, and can be specifically designed according to the structural size of the peritoneal dialysis tubing end, with the ability to completely wrap the peritoneal dialysis tubing end as a design standard.

[0040] In addition, the present invention is provided with a visual window structure for observing the peritoneal dialysis tubing end on the upper shell 1 and / or the lower shell 2, so as to facilitate the observation of the liquid delivery situation of the peritoneal dialysis tubing end. Specifically, the visual window structure is provided on the upper shell 1, and a long strip opening is provided at the center of the upper shell 1, and a tubular structure is provided extending from the opening to the inside of the protective sleeve outer shell. Corresponding to the above structure of the upper shell 1, the present invention is provided with a hole structure on the content, which is used to be sleeved on the extended tubular structure. The tubular structure can contact the surface of the peritoneal dialysis tubing end after the upper shell 1 and the lower shell 2 are closed, so that the peritoneal dialysis tubing end can be observed through the visual window structure.

[0041] Based on the above structural design, the present invention can be provided with a long strip of transparent structure, which is used to replace the tube structure and be installed on the visual window structure, so as to avoid partial exposure of the peritoneal dialysis pipeline end and improve the airtightness of the present invention. At the same time, the peritoneal dialysis pipeline end can also be observed through the transparent structure.

[0042] In another structural optimization of the present invention, the present invention can also provide liquid injection holes (liquid injection holes are provided with soft rubber plugs) on the upper shell 1 and the lower shell 2, so that iodine tincture liquid can be injected into the contents in real time.

[0043] As can be seen from the above, the present invention provides a peritoneal dialysis tubing end connection protective sleeve. In the present invention, the peritoneal dialysis tubing end connection protective sleeve comprises: a protective sleeve outer shell, the protective sleeve outer shell comprises an upper shell 1 and a lower shell 2 that can be opened and closed, and a lock 3 for locking the protective sleeve outer shell after the upper shell 1 and the lower shell 2 are closed is arranged on the protective sleeve outer shell; contents, the contents are made of a material that can absorb disinfection liquid, and the contents are elastic materials, and the contents are arranged on the upper shell 1 and the lower shell 2, and are used to wrap the peritoneal dialysis tubing end after the upper shell 1 and the lower shell 2 are closed.

[0044] Through the above-mentioned structural design, the peritoneal dialysis tubing end connection protective sleeve provided by the present invention can flexibly wrap the peritoneal dialysis tubing end, thereby protecting and reinforcing the tubing connection structure of the peritoneal dialysis tubing end, and improving the connection strength and connection reliability between the peritoneal dialysis tubing end and other tubings during the activities of the dialysis patient, avoiding the problem of tube detachment. In addition, the contents can also absorb the disinfection liquid, and when the contents wrap the peritoneal dialysis tubing end, they can also play a role in disinfection and protection. The present invention can protect the dialysis tubing joint during the dialysis process, thereby protecting it and reducing its disconnection risk and contamination risk.

[0045] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
