Description

Technical Field

[0001] The present invention belongs to the technical field of medical equipment, and particularly relates to a device for preventing blood coagulation and blockage in PICC and cleaning it up. Background Art

[0002] The central venous catheter is abbreviated as PICC in English, and it is a catheter placed in a large vein. It is a kind of venous access. In critically ill patients or patients who need long-term intravenous treatment, it is usually necessary to place a larger catheter in a more central vein to obtain a more reliable vascular access. During application, a part of the catheter needs to be left on the human body. When cleaning up blood coagulation and blockage, the catheter is docked, and then pulled out after use.

[0003] Since when disassembling the catheter, one hand needs to hold the docking seat, and the other hand needs to hold the docking tube. When the pipeline disengages instantaneously during the force application process, the hand needs to be braked in time. If the braking is not timely, the hand will drive the reserved tube greatly and cause harm to the human body, thus resulting in a relatively low safety factor for the separation of the conventional central venous catheter connection.

[0004] Therefore, we propose a device for preventing blood coagulation and blockage in PICC to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem in the prior art that the safety factor for the separation of the conventional central venous catheter connection is relatively low, and to propose a device for preventing blood coagulation and blockage in PICC.

[0006] To achieve the above purpose, the present invention adopts the following technical scheme: A device for preventing blood coagulation and blockage in PICC includes a rotating knob, a connection pipe seat, a socket seat, an elastic braking button and an elastic reset seat. The connection pipe seat movably penetrates through the socket seat. A pair of elastic braking buttons are provided, the front end of the elastic braking button is fixedly connected to the socket seat. A pair of elastic reset seats are provided, the rear end of the elastic reset seat is fixedly connected to the socket seat. A pair of rotating knobs are provided, the rotating knobs are rotatably installed at the front of the elastic reset seat, and the elastic braking buttons are movably clamped outside the connection pipe seat.

[0007] First, pinch the elastic braking button with one hand to clamp and fix the connection pipe seat by using the elastic braking button. Then, press the middle part of the rotating knob with the other hand to make the rotating knob clamp outside the central venous catheter at the front of the connection pipe seat. Then, transfer the pressure to the rear part of the rotating knob to make the rotating knob deflect and drive the central venous catheter at the front side of the connection pipe seat to move forward. Similarly, repeatedly operate the rotating knob until the central venous catheter disengages from the connection pipe seat, reducing the possibility that the hand is difficult to brake caused by instantaneous detachment and improving the safety of use.

[0008] Preferably, the connecting pipe seat includes a sleeve pipe and a connecting pipe, and the connecting pipe and the sleeve pipe are fixedly connected as a whole.

[0009] The sleeve pipe facilitates the docking of the connecting pipe seat with the central venous catheter.

[0010] Preferably, the socket seat includes a binding frame and a support seat, and the rear end of the support seat is fixedly connected to the front end of the binding frame.

[0011] When the rotating knob drives the elastic reset seat to contract and then supports the front part of the elastic reset seat, it facilitates the elastic reset seat to support the rotating knob through the support seat to provide a forward acting force for the rotating knob, improving the stability of the rotating knob to push open the target catheter.

[0012] Preferably, the elastic braking button includes a spring piece and a leather block, and the upper end of the leather block is fixedly connected to the lower rear part of the spring piece.

[0013] The leather block increases the friction force of the elastic braking button on the connecting pipe, improving the firmness of clamping the connecting pipe after the rear part of the spring piece is pressed down.

[0014] Preferably, the elastic braking button further includes a leather button, and the lower end of the leather button is fixedly connected to the upper rear part of the spring piece.

[0015] The leather button increases the softness between the finger and the spring piece, improving the comfort of operating the elastic braking button.

[0016] Preferably, the elastic reset seat includes a spring bar and a bearing sleeve, and there is a pair of the spring bar and the bearing sleeve. The upper end of the bearing sleeve is fixedly connected to the front part of the spring bar.

[0017] The elastic force of the spring bar acts on the bearing sleeve, and through the bearing sleeve acts on the rotating knob, facilitating the rotating knob to maintain an unfolded state, thereby reducing the shielding rate of the sleeve pipe for assembling the catheter.

[0018] Preferably, the elastic reset seat further includes a cushion block, and the cushion block is fixedly connected to the rear part of the bearing sleeve.

[0019] By placing the cushion block between the bearing sleeve and the support seat, it facilitates the support seat to support the bearing sleeve.

[0020] Preferably, the rotating knob includes a pressing frame, a pressing wheel and a return spring. The pressing frame is symmetrically fixedly connected to the side of the pressing wheel, and the side end of the return spring is fixedly connected to the pressing wheel.

[0021] Pinch the middle of the pressing frame with one hand, so that the pressing frame drives the pressing wheel to squeeze the target catheter inward, and then pinch the rear part of the pressing frame, so that the pressing frame deflects backward, using the pressing frame to drive the pressing wheel to push the target catheter outward. Similarly, operate multiple times until the target catheter is separated from the sleeve pipe, facilitating the disassembly of the target catheter.

[0022] Preferably, the rotary squeeze button further includes a shift lever, which is located at the rear of the pressing frame, and the side end of the shift lever is fixedly connected to the pressing frame.

[0023] The shift lever blocks the fingers, improving the stability of hand-squeezing the pressing frame.

[0024] Preferably, the rotary squeeze button further includes a connecting rod, which is located at the front of the pressing frame, and the side end of the connecting rod is fixedly connected to the pressing frame.

[0025] The connecting rod is fixedly connected to the front of the pressing frame, improving the stability of the front spacing of the pressing frame.

[0026] In summary, the technical effects and advantages of the present invention are as follows: 1. First, pinch the elastic brake button tightly with one hand, use the elastic brake button to clamp and fix the connecting pipe seat, and then press the middle part of the rotary squeeze button with the other hand, so that the rotary squeeze button is clamped outside the central venous catheter at the front of the connecting pipe seat. Then transfer the pressure to the rear part of the rotary squeeze button, so that the deflection of the rotary squeeze button drives the central venous catheter on the front side of the connecting pipe seat to move forward. Similarly, operate the rotary squeeze button repeatedly until the central venous catheter is separated from the connecting pipe seat, reducing the possibility of difficult hand braking caused by instantaneous detachment and improving the use safety.

[0027] 2. When the rotary squeeze button drives the elastic reset seat to contract and then supports at the front of the elastic reset seat, it is convenient for the elastic reset seat to provide a forward acting force for the rotary squeeze button by means of the support seat, improving the stability of the rotary squeeze button to push open the target catheter.

[0028] 3. Through the elastic force of the elastic strip acting on the bearing sleeve and then acting on the rotary squeeze button through the bearing sleeve, it is convenient for the rotary squeeze button to maintain the unfolded state, thereby reducing the shielding rate of the catheter assembled by the sleeve pipe.

[0029] 4. Pinch the middle part of the pressing frame with one hand, so that the pressing frame drives the pressing wheel to squeeze the target catheter inward, and then pinch the rear part of the pressing frame, so that the pressing frame deflects backward, and use the pressing frame to drive the pressing wheel to push the target catheter outward. Similarly, operate multiple times until the target catheter is separated from the sleeve pipe, facilitating the disassembly of the target catheter. BRIEF DESCRIPTION OF THE DRAWINGS
