Description

Technical Field

[0001] The utility model relates to the technical field related to medical devices, in particular to a compression cuff for intravenous injection. Background Art

[0002] At present, when hospitals and clinics perform intravenous injections, they need to tie the arms and calves with a cuff first to make the veins at the injected site protrude, so as to facilitate the insertion of the injection needle into the veins. However, the cuffs currently used are generally used repeatedly with a latex tube. However, for different patients, especially those with infectious diseases, it is necessary to disinfect before or after use. Such repeated disinfection is troublesome and reduces the elasticity of the latex tube, which affects normal use. In addition, the tightening process is relatively cumbersome, and the long-term operation is very tiring. At the same time, it is easy to clamp the human skin when tying the knot, causing pain or injury.

[0003] The patent application number 201821606496.7 relates to a compression cuff, including a rubber hose and a fixed end, the fixed end is composed of a fixing seat and a clamping block, one end of the rubber hose is fixedly connected to a side wall of the fixing seat, a guide groove is provided at the upper end of the fixing seat, the clamping block is connected to the guide groove through a telescopic rod, a first spring is also provided between the clamping block and the guide groove, the first spring surrounds the outside of the telescopic rod, through holes are provided on both sides of the fixing seat, the through holes are connected to the guide groove, the other end of the rubber hose extends into the through hole on one side of the fixing seat and extends out from the through hole on the other side, the part of the rubber hose extending into the guide groove is fixed by the clamping block, and a locking mechanism is also provided between the clamping block and the fixing seat. This design has the advantages of simple structure, easy manufacture, practicality and high efficiency.

[0004] The above-mentioned compression cuff has the following disadvantages: when in use, one end of the compression cuff needs to be passed through the through hole on the side of the fixing seat. Due to factors such as angle and light, it cannot be inserted in one go. When removing the compression cuff, it is necessary to continuously press the clamping block and pull the fixing seat, which affects the work efficiency of medical staff. Utility Model Content

[0017] Reference Figure 1-3 A compression cuff for intravenous injection comprises a base band 1 and a fixing mechanism arranged at one end of the base band 1, wherein the base band 1 has a flat cross-section as a whole, and a plurality of fixing blocks 2 are evenly distributed on the outer surface of the base band 1, and the fixing mechanism is composed of a base 3, a groove 4 is provided in the middle of one side of the base 3, and a movable pin block 5 is provided in the groove 4 of the base 3, and an installation cavity 6 is provided inside the end of the base 3 away from the base band 1, and the installation cavity 6 is connected with the groove 4 through a through hole 7, and a reset mechanism is provided in the installation cavity 6 of the base 3, and the reset mechanism is connected with the movable pin block 5.

[0018] The reset mechanism includes a movable plate 8, a compression spring 9 and a movable rod 10. The movable rod 10 and the compression spring 9 are respectively arranged on the upper and lower sides of the movable plate 8. The lower end of the movable rod 10 is fixedly connected to the upper surface of the movable plate 8. The upper end of the movable rod 10 passes through the through hole 7 and is fixedly connected to the movable pin block 5.

[0019] A limiting plate 11 is provided on the outer side of the middle part of the movable rod 10, and the upper surface of the limiting plate 11 abuts against the outer side of the lower end of the through hole 7 to limit the movable rod 10 and the movable pin block 5, ensuring that when the movable pin block 5 is in the uppermost position, there is a gap between the upper end of the movable pin block 5 and the inner wall of the groove 4, so that the base band 1 can be quickly placed in the groove 4.

[0020] Both ends of the compression spring 9 abut against the lower surface of the movable plate 8 and the inner wall of the installation cavity 6 respectively.

[0021] An arc-shaped support plate 12 is disposed on the upper end surface of the base 3 , and a sponge pad 13 is disposed on the inner side of the arc-shaped support plate 12 .

[0022] A pressing pad 14 is provided on the inner surface of the middle portion of the base belt 1 .

[0023] When the device is used, the base band 1 is wrapped around the arm as a whole, with one side of the pressing pad 14 facing the arm, and the other end of the base band 1 is placed in the groove 4. After holding the base 3 with the hand, the base band 1 is pulled to tighten the base band 1, and finally an intravenous injection is performed.

[0024] In the process of pulling the baseband 1, the baseband 1 drives the outer fixed block 2 to move synchronously, and the fixed block 2 moves quickly in the groove 4. After the baseband 1 is tightened, the elastic force of the compression spring 9 pushes out the movable pin block 5, limits the side of the fixed block 2, and ensures that the baseband 1 is in a tightened state.

[0025] When the injection is completed, the movable end of the base belt 1 can be directly separated from the base 3 by directly pulling the end of the base belt 1 away from the base 3 toward the end away from the groove 4 .
