Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a catheter which can prevent the catheter from being folded. Background Art

[0002] Medical catheters are a commonly used delivery structure in hospitals, including infusion pipes, diversion pipes, etc. The material of the catheter is generally rubber products, so it has good bending performance. Infusion bags or diversion bags generally have a hard plastic tube inserted and fixed at the top, so that the catheter can be connected to the inside of the bag through the plastic tube. At present, when the catheter is connected, due to the different materials and hardness of the two ends of the connection port of the catheter, the catheter is prone to bend at the interface. In order to improve the efficiency of liquid flow, a catheter is needed, but the existing catheter still has the following shortcomings:

[0003] For example, the utility model with application number 202120233499.6 discloses a medical catheter, which solves the problem that the safety of the medical catheter is reduced due to the large traction force required when adjusting the bending degree of the medical catheter using a bending wire. However, similar to the comparative documents of the above-mentioned application, when the existing catheter is used, due to the different materials and hardness at both ends of the connection port of most catheters, the catheter is prone to bending at the interface, which makes subsequent catheter drainage unsmooth, resulting in reduced practicality of the catheter and reduced use efficiency.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a catheter that prevents the catheter from being bent is proposed. Utility Model Content

[0005] The utility model aims to provide a catheter which can prevent the catheter from being folded, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a catheter for preventing the catheter from being bent, comprising an infusion bag main body and a first protective ring, a receiving block is arranged in the middle of the upper end of the infusion bag main body, and a threaded mounting block is installed on the upper end of the receiving block, and a mounting ring is connected to the outside of the threaded mounting block, and the middle end of the outside of the mounting ring is connected to the infusion catheter main body, a clamping groove is arranged on the outside of the infusion catheter main body, and a clamping block is connected inside the clamping groove, and a first protective ring is installed on the outside of the clamping block, and clamping grooves are arranged on both sides of the outside of the first protective ring, a magnetic strip is added inside the clamping groove, a first heating block is added to the rear end of the inside of the first protective ring, and a second protective ring is distributed outside the first protective ring, and a second heating block is added to the rear end of the inside of the second protective ring, and docking magnetic blocks are added on both sides of the outside of the second protective ring.

[0007] Furthermore, the threaded mounting block and the receiving block are vertically distributed, and the threaded mounting block and the receiving block are fixedly connected.

[0008] Furthermore, the outer dimensions of the threaded mounting block match the inner dimensions of the mounting ring, and the mounting ring is rotatably connected to the threaded mounting block.

[0009] Furthermore, the inner dimensions of the clamping groove match the outer dimensions of the clamping block, and the clamping block is slidably connected to the mounting ring via the clamping groove.

[0010] Furthermore, the first protection ring is in a hollow semi-cylindrical shape, and the inner size of the first protection ring matches the outer size of the mounting ring.

[0011] Furthermore, the inner dimensions of the slot match the outer dimensions of the docking magnetic block, and the docking magnetic block is connected to the first protective ring through the slot.

[0012] Furthermore, the outer side of the first heating block is flush with the inner side of the first protective ring, and the outer side of the first heating block is tightly fitted with the inner side of the first protective ring.

[0013] Furthermore, the docking magnetic blocks are symmetrically arranged on both sides of the outside of the second protective ring, and the docking magnetic blocks are fixedly connected to the second protective ring.

[0014] The utility model provides a catheter that prevents the catheter from being folded, and has the following beneficial effects:

[0015] 1. The utility model can prevent the catheter from being bent when using the catheter by setting the first protective ring. The first protective ring arranged outside the mounting ring can avoid the problem that the catheter is easily bent at the interface due to the different materials and hardness at the two ends of the connection port of most catheters, which makes the subsequent catheter drainage unsmooth and causes the practicality of the catheter to decrease. The inner size of the mounting ring matches the outer size of the threaded mounting block. The mounting ring is rotatably mounted on the outside of the threaded mounting block, so that the infusion catheter body is limitedly mounted on the outside of the infusion bag body. At the same time, the inner size of the clamping groove provided on the outside of the mounting ring matches the outer size of the clamping block. Then, the first protective ring is slidably mounted on the outside of the mounting ring through the clamping block and the clamping groove. The extended first protective ring is used to protect the infusion catheter body and the threaded mounting block arranged at the front end of the infusion bag body, thereby avoiding bending at the connection and improving the efficiency of catheter use.

[0016] 2. The utility model can prevent the catheter from being bent by setting the first heating block. When the catheter is used, the first heating block set inside the first protective ring can prevent most catheters from not having the performance of heating during the liquid delivery process, resulting in discomfort caused by the low temperature of the liquid entering the human body, resulting in reduced mobility of the catheter. The first heating block is fixedly installed at the inner rear end of the first protective ring through the fastener, and the second heating block is fixedly installed at the inner rear end of the second protective ring with the fastener. At the same time, the inner size of the card slot opened on both sides of the outside of the first protective ring matches the outer size of the docking magnetic blocks added on both sides of the outside of the second protective ring, and the docking magnetic blocks are magnetically attracted to the magnetic strips set inside the card slot, so that the first protective ring is connected to the second protective ring through the card slot and the docking magnetic block, so that the first heating block cooperates with the second heating block to form a complete circular ring, and when the first heating block and the second heating block are in operation, the infusion catheter body set inside the first protective ring and the second protective ring is heated, thereby preventing the liquid temperature from being too low and increasing the comfort during the infusion process.
