Description

Technical Field

[0001] The utility model relates to the technical field of central venous catheters, in particular to a fixing component for a central venous catheter. Background Technique

[0002] Central venous pressure (CVP) refers to the pressure of blood flowing through the right atrium and the thoracic segments of the superior and inferior vena cava. Generally, the pressure of the superior vena cava near the right atrium is measured. It can be directly measured by inserting a central venous catheter. Earlier, it was mainly regarded as an index for evaluating cardiac preload and was often used clinically to guide the infusion rate and volume of fluid therapy. With the continuous in-depth clinical research, CVP is now one of the most commonly used hemodynamic monitoring indicators in fluid resuscitation of critically ill patients. When conducting central venous catheterization, a fixing frame is required to fix between the saline bag and the injection head.

[0003] In the prior art, during use, it is impossible to adjust and fix according to the lengths of the injection head and the drip chamber, and it is not applicable to fix drip chambers at different positions. Content of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages in the prior art that during use, it is impossible to adjust and fix according to the lengths of the injection head and the drip chamber, and it is not applicable to fix drip chambers at different positions, and to propose a fixing component for a central venous catheter.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A fixing component for a central venous catheter, comprising:

[0007] A first clamping cylinder and a second clamping cylinder;

[0008] Semicircular clamping holes are arranged at the top of the first clamping cylinder. There are two semicircular clamping holes, and the two semicircular clamping holes are symmetrically arranged on the first clamping cylinder and the second clamping cylinder respectively. An articulated plate is hinged between the first clamping cylinder and the second clamping cylinder;

[0009] A clamping frame is fixedly arranged on the first clamping cylinder. There are two clamping frames, and the two clamping frames are equidistantly located on the first clamping cylinder;

[0010] Clasps are fixedly arranged on the second clamping cylinder. There are two clasps, and the two clasps are equidistantly located on the second clamping cylinder. The two clasps are respectively matched with the two clamping frames.

[0011] Furthermore, hollow observation places are arranged on both the first clamping cylinder and the second clamping cylinder, and the two hollow observation places are symmetrically arranged.

[0012] Furthermore, a plurality of adjustment holes are provided between the first cartridge and the second cartridge, and triangular hooks are provided in two of the adjustment holes.

[0013] Furthermore, vertical plates are fixedly connected to the bottoms of the two triangular hooks, and a support cylinder is fixedly connected to the bottoms of the two vertical plates.

[0014] Furthermore, a vertical hole is provided in the support cylinder, and a limit hole is provided at the bottom of the support cylinder, and the limit hole is connected to the vertical hole.

[0015] Compared with the prior art, the advantages of the present utility model are as follows:

[0016] In this solution, since the drip funnel on the catheter is located in the support cylinder and is supported by the limit hole, when the patient pulls the catheter, the situation where the plug of the infusion catheter is separated from the saline bag is avoided.

[0017] The structure of the present utility model is simple, and the fixed length can be adjusted according to requirements, which is beneficial to wide promotion and convenient for people to use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings in the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0024] Embodiment

[0025] Refer to Figures 1-4, a fixing component for a central venous catheter, comprising:

[0026] a first cartridge 1 and a second cartridge 13;

[0027] semicircular clamping holes 2 are arranged at the top of the first cartridge 1, and two semicircular clamping holes 2 are provided. The two semicircular clamping holes 2 are symmetrically arranged on the first cartridge 1 and the second cartridge 13 respectively. An articulated plate 3 is hinged between the first cartridge 1 and the second cartridge 13;

[0028] a clamping frame 4 is fixedly arranged on the first cartridge 1. Two clamping frames 4 are provided and are equidistantly located on the first cartridge 1;

[0029] a buckle 5 is fixedly arranged on the second cartridge 13. Two buckles 5 are provided and are equidistantly located on the second cartridge 13. The two buckles 5 are respectively matched with the two clamping frames 4.

[0030] In this embodiment, hollow observation parts 6 are arranged on both the first cartridge 1 and the second cartridge 13, and the two hollow observation parts 6 are symmetrically arranged.

[0031] In this embodiment, a plurality of adjusting holes 7 are opened between the first cartridge 1 and the second cartridge 13, and triangular hooks 8 are arranged in two of the adjusting holes 7.

[0032] In this embodiment, vertical plates 9 are fixedly connected to the bottoms of the two triangular hooks 8, and a supporting cylinder 10 is fixedly connected to the bottom ends of the two vertical plates 9.

[0033] In this embodiment, a vertical hole 11 is opened on the supporting cylinder 10, and a limiting hole 12 is opened at the bottom of the supporting cylinder 10. The limiting hole 12 is connected to the vertical hole 11.

[0034] The implementation principle of the fixing component for a central venous catheter in the embodiment of the present application is as follows: Close the first cartridge 1 and the second cartridge 13 at the bottom head of the saline bag, so that the two semicircular clamping holes 2 are clamped on the bottom of the saline bag. By clamping the two clamping frames 4 on the two buckles 5, the plug of the infusion catheter and the catheter pass through the limiting hole 12 and are located between the first cartridge 1 and the second cartridge 13, and then inserted into the saline bag. The drip chamber on the catheter is located in the supporting cylinder 10, and is supported by the limiting hole 12, so as to avoid the situation that the plug of the infusion catheter is separated from the saline bag when the patient pulls the catheter. The two triangular hooks 8 can be placed in two of the adjusting holes 7 on the same horizontal line, so that the fixing length can be adjusted according to needs.
