Description

Technical Field

[0001] The utility model belongs to the technical field of infusion set exhaust, and in particular relates to an infusion set exhaust clip. Background Art

[0002] Infusion sets are common medical consumables. After sterilization, a channel between the vein and the liquid medicine is established for intravenous infusion. Due to the drug itself or improper operation, air is injected into the infusion. For clinical nurses, common methods to exhaust the air in the infusion set are the winding infusion tube exhaust method and the finger flicking infusion tube exhaust method. The winding infusion tube exhaust method is to adjust the liquid regulator to the bottom of the infusion tube and close the liquid. Extend the left index finger and wrap the infusion tube clockwise around the index finger. Use a certain amount of force when winding, and press the latter circle on the previous circle to achieve the purpose of driving the gas in the infusion tube. In order to prevent the top of the infusion tube from being folded, it can be rotated 90° each time it is wrapped; when the liquid reaches the Murphy's dropper, squeeze the Murphy's dropper with your right hand, and release your right hand after 1 / 3 of the gas is discharged, and the exhaust is over. The finger flicking infusion tube exhaust method is to close the infusion tube and squeeze the Murphy's dropper hard to remove 1 / 3 of the gas. Hold the bottom of the infusion tube with your left hand, and use the middle finger of your right hand to flick the infusion tube to make the liquid go down and the gas go up. During the operation, make sure there is liquid in the Murphy's dropper.

[0003] The above common operation methods are troublesome and waste time for caregivers. If similar situations occur 2-3 times a day, the caregivers' hands are prone to soreness. Summary of the invention

[0004] The utility model aims to design an infusion set exhaust clamp, which can clamp the infusion tube of the infusion set and exhaust air by squeezing.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] The infusion set exhaust clamp is composed of a first clamp body, a second clamp body and a connecting part. The first clamp body and the second clamp body are closed by a locking structure. A frame is provided in the middle part of the first clamp body. A rotatable squeezing roller is installed in the frame. The first clamp body and the second clamp body are ensured to be firmly closed by a limiting structure.

[0007] Furthermore, the connection portion adopts a connection belt or a hinged structure, so that the connection method can be designed and selected according to actual needs.

[0008] Furthermore, the locking structure is specifically that a clamping block is provided at the end of the first clamping body, and a buckle is provided at the end of the second clamping body, and when the clamping bodies are closed, the clamping block is locked into the buckle.

[0009] Furthermore, both ends of the rotating shaft of the squeezing roller are located on the bearings of the frame, and the rotating shaft direction of the squeezing roller is horizontally arranged with the first clamp. The reason for this arrangement is that the exhaust clamp of the utility model is vertically arranged with the infusion tube, and the rotating shaft is horizontally arranged with the first clamp, thereby ensuring that the squeezing roller can rotate on the infusion tube.

[0010] Furthermore, the limiting structure is specifically that a limiting groove is provided in the first clamp body, and a limiting plug-in is provided in the second clamp body. When the clamp bodies are closed, the limiting plug-in is smoothly inserted into the limiting groove. The limiting structure is conducive to the effective combination of the first clamp body and the second clamp body when they are closed, preventing displacement or misalignment between the two.

[0011] Furthermore, pull rings extend from the sides of the first clamp and the second clamp, and the existence of the pull rings facilitates the operation and movement of the clamps.

[0012] Furthermore, a triangular protrusion is raised on the top of the frame. The triangular protrusion is used to reserve a gap and prevent the infusion tube from escaping from the range of the squeezing roller. The reserved gap can meet the thickness requirement of the infusion tube after being squeezed.

[0013] Compared with the prior art, the above technical solution can achieve the following beneficial effects:

[0014] The utility model structure can perfectly exhaust the air in the infusion set and is very simple to use, without the need for complicated operations such as winding or flicking the infusion tube by the nursing staff.

[0015] The utility model places the infusion tube in the squeezing roller by the cooperation of two clamping bodies, and after the clamping bodies are locked, exhaust can be completed by pulling the pull ring by hand, and the whole process is simple and easy to use.

[0016] The utility model adopts an extrusion roller structure, which is conducive to sequential movement during extrusion, and adopts a limiting structure to ensure accelerated closing stability and prevent displacement or misalignment of the two. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The utility model is further described below in conjunction with the accompanying drawings:

[0024] Example 1: Figure 1-4 As shown, the infusion set exhaust clamp is composed of a first clamp body 1, a second clamp body 2 and a connecting portion. The connecting portion in this embodiment adopts a connecting belt. The first clamp body 1 and the second clamp body 2 are closed by a locking structure. In this embodiment, the locking structure is specifically that a clamp block 3 is provided at the end of the first clamp body 1, and a buckle 4 is provided at the end of the second clamp body 2;

[0025] A frame 8 is provided in the middle of the first clamping body 1, and both ends of the rotating shaft 9 of the squeezing roller 7 are seated on the bearings of the frame 8. The rotating shaft of the squeezing roller 7 is placed in a horizontal direction with the first clamping body 1. Two limiting grooves 6 are symmetrically provided on the first clamping body 1 with the frame 8, and two limiting plug-ins 5 are also provided on the second clamping body;

[0026] When the clamp body is closed, the limiting plug-in 5 is smoothly inserted into the limiting groove 6 , and the clamping block 3 is clamped into the buckle 4 at the same time.

[0027] For example, when air is found in the infusion tube of the upper part of the drip pot, the infusion tube is placed perpendicular to the clamp body, and then placed on the squeezing roller 7, and the clamp body is closed. At this time, the limiting plug-in 5 is smoothly inserted into the limiting groove 6, and the block 3 is locked in the buckle 4. The nursing staff inserts two fingers into the pull ring and pulls it down hard. If air is found in the infusion tube of the lower part of the drip pot, it can be pulled upward according to the above method.

[0028] In the above embodiment, the limiting plug-in 5 is a sheet-shaped piece or a long strip plug-in block, which has a better limiting effect.

[0029] In the above embodiment, a triangular protrusion is raised on the top of the frame, and the inclined surfaces of the triangular protrusions on both sides face the infusion tube, which can effectively limit the movement of the infusion tube in the frame to prevent it from detaching. The height of the triangular protrusion is equal to the thickness of the squeezed infusion tube wall, which prevents the infusion tube from being damaged by excessive squeezing.

[0030] In the above embodiments, the locking structure is only a preferred method. In practical applications, we can choose various structures with locking functions.

[0031] In the above embodiment, the infusion set exhaust clamp can also be installed on the top of the infusion tube, and slid up and down along the infusion tube to input the liquid medicine in the infusion tube into the drip pot as quickly as possible, so as to facilitate the replacement of the next infusion bag.

[0032] The liquid in the lower part of the infusion tube of the drip pot is rolled and squeezed to inject the remaining liquid into the body to reduce liquid waste. The squeezing speed needs to be consistent with the infusion speed to prevent rapid injection into the body.

[0033] The above are all preferred implementations of the present invention. For ordinary technicians in this technical field, without departing from the principle of the present invention, various equivalent modifications to the present invention belong to the protection scope of the claims attached to this application.
