Abstract
Description
Technical Field
[0001] The invention relates to the field of medical devices, and in particular to a medical pipe clamp. Background Art
[0002] Disposable medical consumables are used in blood collection and blood processing procedures. These consumables usually include various collection containers, multiple hoses of different lengths for communication and liquid transfer between components, and some also require the connection of venous access devices (such as blood collection devices) that can be inserted into the patient's or donor's arm for blood collection or transfusion. During the blood collection and processing process, one or more different points on the consumables need to be closed to prevent the flow of liquid in that section of the pipeline. To do this, a clamp can be set on the pipeline on the consumables. This type of clamp deforms the hose itself through external force, causing the pipeline to deform and be blocked, so that the liquid cannot flow through the position of the clamp. In some cases, the pipeline needs to be permanently or semi-permanently closed to block the liquid.
[0003] The above-mentioned problems of disposable medical tube clamps in the prior art are as follows:
[0004] 1. They are already fixed on the pipeline when they are produced and cannot be removed or installed by themselves. Medical staff can only scrap them after use, which results in a large waste of medical resources.
[0005] 2. Dedicated pipe for dedicated use: For different pipelines, the pipe diameter needs to match the pipe clamp before it can be used. Once the pipe clamp is unqualified or damaged for other reasons, the entire pipeline cannot be used anymore. Summary of the invention
[0006] The purpose of the present invention is to solve the above shortcomings in the prior art and to propose a medical tube clamp.
[0007] To achieve the above object, the present invention adopts the following technical solutions:
[0008] A medical tubing clamp comprises a free end clamping portion, a fixed end clamping portion, a clamping connection portion, and a free end limiting portion, wherein the free end clamping portion and the fixed end clamping portion are connected via a clamping connection portion, the free end clamping portion is provided with a free end clamping portion protrusion, the fixed end clamping portion is provided with a fixed end clamping portion protrusion, a guide protrusion is provided at the end of the free end clamping portion, a hose insertion port is provided in the vertical direction of the arcuate surface of the clamping connection portion, and a hose insertion port is provided in the vertical direction of the arcuate surface between the free end limiting portions, characterized in that: the medical tubing clamp is split longitudinally into a tubing clamp half A and a tubing clamp half B, and the tubing clamp half A and the tubing clamp half B match each other.
[0009] Furthermore, the fixed end clamping parts of the pipeline clamp half A and the pipeline clamp half B are fixedly connected together through a connecting shaft.
[0010] Furthermore, the pipe clamp half A and the pipe clamp half B can rotate freely through the connecting shaft of the fixed end clamping part.
[0011] Furthermore, matching buckle assemblies are provided on the outer sides of the free end clamping parts of the pipeline clamp half A and the pipeline clamp half B.
[0012] Furthermore, the snap assembly is a baffle on the pipe clamp half A and a fastening piece on the pipe clamp B. The baffle matches the fastening piece, the baffle is integrally connected to the pipe clamp half A, and the fastening piece is integrally connected to the pipe clamp half B.
[0013] Furthermore, the cross section of the baffle is trapezoidal, with a right side having an inclined surface extending in the longitudinal direction; the fastener has a groove, and a tip having an inclined surface matching the inclined surface of the baffle.
[0014] Furthermore, the free end clamping protrusion and the fixed end clamping protrusion of the pipe clamp half A both have protruding support parts in the lateral direction, and the free end clamping protrusion and the fixed end clamping protrusion of the pipe clamp half B are truncated parts, and the support parts match the truncated parts.
[0015] Furthermore, a through hole is provided on the protrusion of the free end clamping portion. Since the free end clamping portion is too large, the provision of the through hole can reduce the overall weight and reduce material consumption without affecting the use.
[0016] Furthermore, the outer side of the free end clamping portion has an anti-slip protrusion, and the inner side of the free end limiting portion has an anti-slip protrusion.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] 1. Since the pipe clamp is divided into two parts, the pipe clamp half body A and the pipe clamp half body B, it is not necessary to use a specific pipe for a specific purpose. As long as the condition that the hose can pass through the pipe clamp's inlet and outlet is met, the pipe clamp of the present invention can be installed on the pipe. Therefore, the present invention is applicable to pipes of various diameters;
[0019] 2. Since the pipe clamp is divided into two parts, the pipe clamp half body A and the pipe clamp half body B, the pipe clamp of the present invention can be installed on the pipe more conveniently and quickly, thus saving a lot of medical resources;
[0020] 3. When the pipe clamp half A and the pipe clamp half B are buckled together, the support part on the pipe clamp half A and the cut-off part of the pipe clamp half B are matched and connected, so that when in use, the outward diastolic pressure of the passing hose will only press the free end clamping part protrusion and the fixed end clamping part protrusion of the pipe clamp half A, which can avoid the pipe clamp half A and the pipe clamp half B from collapsing.
