Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a protection device for a central venous catheter of a dialysis patient. Background Art

[0002] With the continuous development of technology, more and more diseases can be inhibited or treated through medical means, so that patients can recover to a healthy state. The central venous catheter belongs to a kind of intravascular catheter and is placed in the large vein. Clinically, it is mainly applicable to critically ill patients who need intravenous nutrition, antibiotic treatment, chemotherapy, hemodialysis, and cannot establish peripheral venous access, as well as patients with severe trauma or acute circulatory failure who need to monitor central venous pressure and receive a large amount of rapid fluid replacement, etc.

[0003] Currently, during the dialysis use of the central venous catheter, the patient is almost in a state where they cannot turn over. Therefore, it is very easy for the patient to make relatively large-amplitude movements, and thus it is very easy for the patient to drive the central venous catheter to move, resulting in the folding and flattening of the central venous catheter, which will affect the subsequent treatment operations of the patient. Therefore, a protection device for a central venous catheter of a dialysis patient is provided. Summary of the Utility Model

[0005] The embodiment of the utility model adopts the following technical solutions: including a central venous catheter body, an upper protective sleeve, a lower protective sleeve, a card slot and a buckle. The central venous catheter body is arranged at the treatment site required by the patient. The upper protective sleeve and the lower protective sleeve are symmetrically arranged and are rotatably connected at one end, and the central venous catheter body is located inside the upper protective sleeve and the lower protective sleeve. There are two card slots, and the two card slots are symmetrically arranged on one side outside the lower protective sleeve. There are two buckles, and the two buckles are symmetrically arranged on one side outside the upper protective sleeve and are in a matching state with the corresponding card slots.

[0006] Further, the upper protective sleeve and the lower protective sleeve are set to form a cylinder. The reason for setting the upper protective sleeve and the lower protective sleeve to form a cylinder in this device is to save the storage space and placement space of the product and reduce the probability of contact with the patient. At the same time, it is also convenient for staff to take.

[0007] Further, both the upper protective sleeve and the lower protective sleeve are made of plastic transparent material.

[0008] Further, storage and fixing grooves matching the central venous catheter body are arranged inside both the upper protective sleeve and the lower protective sleeve.

[0009] Further, it further includes a pull rope, one end of the pull rope is located in the storage and fixing groove inside the lower protective sleeve, and the other end extends out of the storage and fixing groove and is located outside the lower protective sleeve.

[0010] The above at least one technical solution adopted in the embodiment of the present utility model can achieve the following beneficial effects:

[0011] When the central venous catheter needs to be protected during the treatment of the patient in the present utility model, first, the two buckles on the upper protective sleeve are taken out from the corresponding card slots on the lower protective sleeve, then the upper protective sleeve is opened, and then the central venous catheter is placed into the storage and fixing groove on the lower protective sleeve. At this time, one end of the pull rope is located in the lower storage and fixing groove and is located below the central venous catheter. Then, the upper protective sleeve is covered on the central venous catheter, and the upper protective sleeve and the lower protective sleeve are closed by connecting the two buckles with the corresponding card slots. During the treatment process, the situation can be viewed in real time because both the upper protective sleeve and the lower protective sleeve are made of plastic transparent materials. And when the patient moves, the central venous catheter will not be flattened or folded under the protection of the upper protective sleeve and the lower protective sleeve, so as not to affect the subsequent treatment process. When the patient's treatment is completed and the central venous catheter needs to be taken out from the storage and fixing groove, the upper protective sleeve is opened. Since the pull rope is located below the central venous catheter, at this time, just pull the pull rope to facilitate the removal of the central venous catheter. The structure of this device is simple and the operation is easy, so it is convenient for wide use. Description of the Drawings
