Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a disposable central venous catheter aseptic operating cabin for hemodialysis. Background Art

[0002] The infection rate of disposable central venous catheter sterile operation cabin for hemodialysis is relatively high. The sterile operation requirements are strict. The cleanliness of the surrounding air during operation is affected by the patient, the operator and the surrounding environment, which can easily lead to catheter infection, thereby adversely affecting the treatment effect and endangering the patient's health. Utility Model Content

[0003] In view of the problems existing in the existing sterile operation cabin of the disposable central venous catheter for hemodialysis, the utility model is proposed.

[0004] Therefore, the purpose of the utility model is to provide a disposable sterile operating cabin for a central venous catheter for hemodialysis, which solves the problem that the infection rate of the central venous catheter for hemodialysis is high, the sterile operation requirements are strict, and the cleanliness of the surrounding air during operation is affected by the patient himself, the operator and the surrounding environment, which can easily lead to catheter infection, thereby adversely affecting the treatment effect and endangering the patient's health.

[0005] In order to solve the above technical problems, according to one aspect of the present invention, the present invention provides the following technical solutions:

[0006] A disposable central venous catheter sterile operation cabin for hemodialysis comprises an upper transparent portion, a bottom portion and a side portion to form a closed cabin body, wherein an upper valve is installed on the upper transparent portion and a lower valve is installed on the bottom portion.

[0007] As a preferred solution of the disposable central venous catheter aseptic operation cabin for hemodialysis described in the utility model, an air one-way valve is installed on the upper transparent part.

[0008] As a preferred solution of the disposable central venous catheter sterile operation cabin for hemodialysis described in the utility model, wherein: the upper transparent part is made of transparent plastic material.

[0009] As a preferred solution of the disposable central venous catheter sterile operation cabin for hemodialysis described in the utility model, the bottom layer and the side surface are made of waterproof material.

[0010] Compared with existing technologies:

[0011] The whole operation is carried out in a sterile environment, without exposure risk, reducing infection. Because of the waterproof design of this product, there will be no bleeding or liquid leakage due to operational errors. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 This is a structural schematic diagram provided by the utility model.

[0013] In the figure: an air one-way valve 1, an upper transparent portion 2, a bottom portion 3, an upper valve 4, a side portion 5, and a lower valve 6. DETAILED DESCRIPTION

[0014] In order to make the purpose, technical solutions and advantages of the present invention more clear, the implementation methods of the present invention will be further described in detail below with reference to the accompanying drawings.

[0015] The utility model provides a disposable central venous catheter sterile operation cabin for hemodialysis. Figure 1 The upper transparent part 2, the bottom part 3 and the side part 5 form a closed cabin. The upper transparent part 2 is provided with an upper valve 4, the bottom part 3 is provided with a lower valve 6, and the upper transparent part 2 is provided with an air check valve 1. The air check valve 1 has an air filtering function to filter the air and reduce the internal air colony. The upper transparent part 2 is made of transparent plastic material. The transparent material is selected to facilitate visualization and observation of the connection. The bottom part 3 and the side part 5 are made of waterproof material, which can be waterproof paper material.

[0016] The diameter of the lower valve 6 is consistent with the size of the central venous catheter. The diameter of the upper valve 4 is consistent with the diameter of a 5 ml syringe.

[0017] During specific use, the sterilized central venous catheter passes through the lower valve 6 and enters the sterile bag. The syringe connected to it passes through the upper valve and enters the cabin to dock and complete the thrombus withdrawal. The syringe then withdraws from the valve, and the valve can close automatically. Then, the syringe enters through the secondary valve dialysis arteriovenous port and is connected to the arteriovenous end of the catheter.

[0018] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
