Description

A CVC catheter auxiliary transfer device

technical field

The utility model relates to the field of medical equipment, in particular to an auxiliary switching device for a CVC catheter.

Background technique

In the existing medical diagnosis and treatment methods, the medical staff will perform deep venous drainage on the patient. Usually, the medical staff will connect the drainage end of the deep venous drainage end with the drainage end of the negative pressure drainage bottle, so as to drain the accumulated blood in the patient's body. liquid.

In the existing medical technology, the drainage end of the deep venous catheter needs to be connected with the drainage end of the catheter of the negative pressure bottle. The port of the drainage end of the pressure drainage bottle is usually set too large to be directly connected with the drainage end of the deep venous catheter, and the drainage end of the deep venous catheter is provided with an external thread, which is mostly used to connect with the threaded end of the heparin cap, while the negative The drainage end of the pressure drainage bottle is mostly a conical plug-in interface. When in use, medical staff usually use a sterile blade to trim the drainage end of the negative pressure drainage bottle to remove the tapered interface. Since the deep venous catheter and the negative pressure drainage bottle are connected through a heparin cap, the medical staff also need to remove the The apron of the heparin cap, so that the threaded end of the heparin cap is threadedly connected to the end of the deep vein catheter, and the end of the heparin cap without the apron is inserted into the catheter at the drainage end after trimming the negative pressure drainage bottle. Not only is it time-consuming and labor-intensive, but also if the patient is in other places other than the operating room and encounters a sudden attack, the time for trimming the port may cause the patient to miss the best time for treatment.

In addition, nurses will use a flow stop device such as a stop clip to clamp the deep venous drainage tube to control the flow rate of the deep venous tube drainage, which is not convenient and quick enough.

Therefore, it is a technical problem to be solved how to design an auxiliary transfer device that can adapt to the size of the drainage port of various drainage bottles, is convenient to connect, and the transfer device can control the drainage flow rate.

Utility model content

In order to solve the above problems, the purpose of this utility model is to provide a CVC catheter auxiliary transfer device, which solves the problem that the drainage port of the drainage bottle does not match the drainage end interface of the deep vein catheter and cannot be quickly connected, and lacks a device for controlling the drainage flow rate. question.

In order to achieve the above purpose, the utility model adopts the following technical solutions: the main body is an adapter, and the adapter includes a first interface at one end of the adapter, a trumpet-shaped second interface at the other end of the adapter, and a A flow rate adjustment assembly; an adjustment assembly is provided on the outer tube wall of the second interface; the adjustment assembly includes a limit protrusion fixed on the outer tube wall of the second interface and a sleeve sleeved on the outer tube wall of the second interface The adjustment ring; the flow rate adjustment assembly includes an upper limit ring fixed on the outer pipe wall and a lower limit ring fixed on the outer pipe wall; the outer wall of the upper limit ring is fixed with at least three As for the L-shaped limit rod, several limit blocks are fixed on the outer wall of the lower limit ring along the circumferential direction, and the spacing between the limit blocks is equal.

Further, the inner wall of the nozzle of the first interface is provided with an internal thread groove matching the deep vein joint.

The utility model has the following beneficial effects:

1. In the utility model, by setting the flow rate adjustment component, the nurse can flexibly adjust the drainage speed, so as to avoid the patient's physical discomfort caused by the excessive drainage speed.

2. The utility model provides an adapter so that the drainage end of the drainage bottle can be directly connected with the adapter, which is convenient and quick, and improves the working efficiency of the medical staff.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

Referring to Figure 1-2, the main body is an adapter 1, the adapter 1 includes a first interface 11 located at one end of the adapter 1, and the other end of the adapter 1 is trumpet-shaped and made of hose materials such as silica gel and rubber. The completed second interface 12 and the flow rate adjustment assembly 13 located in the middle of the adapter 1 .

An adjustment assembly 14 is provided on the outer tube wall of the second interface 12; The wall is an annular adjusting ring 142 made of silica gel material, in which multiple sets of limiting protrusions 141 are arranged along the axial direction of the second interface 12, so as to facilitate the adjustment and limiting of the position of the adjusting ring 142;

The flow rate adjustment assembly 13 includes an upper limit ring 131 fixed on the outer tube wall and a lower limit ring 132 fixed on the outer tube wall; the outer wall of the upper limit ring 131 is fixed with at least three L-shaped limiting rod 1311 , a plurality of limiting blocks 1321 are fixed on the outer wall of the lower limiting ring 132 along the circumferential direction, and the spacing between the limiting blocks 1321 is equal. The part of the adapter 1 between the upper limit ring 131 and the lower limit ring 132 is a twistable elastic silicone tube or rubber tube, and the length of the limit rod 1311 is shorter than that of the upper limit ring 131 and the lower limit ring 132 In the initial state, the limit rod 1311 has a certain distance from the lower limit ring 132 and is not locked in the limit block 1321. When twisting is required, twist the tube clockwise or counterclockwise body so that the section inside the rubber tube of the adapter 1 located between the upper limit ring 131 and the lower limit ring 132 becomes smaller or closed, and then presses down the limit rod 1311 at the same time, so that the limit rod 1311 is clamped at the limit Block 1321 prevents the rubber tube from swirling. When you need to adjust the flow rate, just twist the tube body in the opposite direction to let the limit rod 1311 break away from the limit block 1321 (if you let go at this time, the tube body will return to the original state by elasticity), and then twist the tube body again to adjust to the appropriate flow rate That's it.

The inner wall of the nozzle of the first interface 11 is provided with an internal thread groove 111 matching with the deep vein joint, which is convenient for medical staff to directly thread the first interface 11 to the external threaded end of the deep vein.

As shown in Figure 1-2, the first interface 11 of the adapter 1 is threadedly connected to the external threaded end of the deep vein, and the negative pressure drainage end of the negative pressure bottle is inserted into the second port 12, and through the The adjustment assembly 14 fixes the negative pressure drainage end (as shown in FIG. 2 , the adjustment ring 142 is pulled down and clamped between the limit protrusions 141 ).

Before the drainage, the medical staff twisted the silicone tube part according to the patient's physical condition, and clamped the limit rod 1311 on the upper limit ring 131 on the limit block 1321 of the lower limit ring 132 to keep it in use, so as to This adjusts the appropriate drainage speed.

The above is only the specific implementation of the utility model, and does not limit the patent scope of the utility model. Any equivalent structural transformation made by using the utility model specification and accompanying drawings, or directly or indirectly used in other related technologies Fields are all included in the scope of patent protection of the utility model in the same way.
