Description

Technical Field

[0001] The utility model relates to the technical field of general nursing, in particular to a compression cuff with adjustable length. Background Art

[0002] A tourniquet is a rubber tube used for intravenous infusion or blood sampling in medical treatment. Its main purpose is to strangle the local area, promote blood filling and make the vein visible, and then perform infusion or blood sampling. It is also called a tourniquet clinically. The method of tying a knot on the tourniquet cannot control the accuracy of the length for intern medical students, which can easily cause pain to patients.

[0003] According to a disclosed length-adjustable compression cuff for nursing teaching (publication number: CN216388426U), in the above application, one end of the rubber hose is fixed in a mounting groove opened on the mounting side through a locking assembly, and the other end of the rubber hose passes through a first perforation and bypasses the bottom of the mounting block to pass through a second perforation. By adjusting the extrusion assembly, the rubber hose located in the cavity is fixed by the extrusion assembly, which facilitates the adjustment of the length of the rubber hose by using the extrusion assembly.

[0004] However, during actual use of the above-mentioned equipment, the length of the rubber hose is adjusted by an extrusion component, but the rubber hose is easily damaged after being squeezed. The service life of the rubber hose will be reduced after long-term extrusion and adjustment, thereby increasing the wear rate of the rubber hose. In view of this, we propose a length-adjustable compression cuff. Utility Model Content

[0005] The utility model aims to provide a cuff with adjustable length to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a length-adjustable compression cuff, comprising a mounting block, the arc-shaped surface of the bottom of the mounting block fits the patient's wrist position, a rubber hose is arranged inside the mounting block, the top of the mounting block is fixedly connected to the end of the handle, and an adjustment structure is arranged outside the rubber hose, and the adjustment structure includes:

[0007] A knob is provided on the side wall of the mounting block, and the knob is convenient for driving the rotating shaft to rotate forward and reverse so that the rotating shaft releases and reels the connecting rope. The end of the knob is fixedly connected to one end of the rotating shaft, and the other end of the rotating shaft is fixedly connected to the side wall of the baffle;

[0008] A connecting rope, wherein the baffle is provided with a connecting rope on the outside, a positioning plate is provided on the outside of the connecting rope, and a groove is provided on the outside of the positioning plate;

[0009] A positioning hole is provided at the top of the groove, and the positioning hole facilitates the insertion of the rubber block so that the positioning plate is connected to the knob, and the inner surface of the positioning hole is adapted to the outer surface of the rubber block.

[0010] Preferably, one end of the connecting rope is fixedly connected to the surface of the rotating shaft, and the other end of the connecting rope is fixedly connected to the surface of the rubber hose.

[0011] Preferably, a groove is formed on the side wall of the mounting block, and an end of the positioning plate is hinged to the inner wall of the groove.

[0012] Preferably, a positioning hole is formed at one end of the knob away from the rotating shaft, and the end of the rubber block is fixedly connected to the inner surface of the positioning plate.

[0013] Preferably, the end of the positioning plate is fixedly connected to one side of magnet one, and the other side of magnet one is magnetically connected to the side wall of magnet two.

[0014] Preferably, the second magnet is located at the bottom of the knob.

[0015] Compared with the prior art, the utility model provides a length-adjustable cuff having the following features:

[0016] Beneficial effects:

[0017] 1. The length-adjustable compression cuff is provided with a knob to drive the rotating shaft so that the connecting rope drives the rubber hose to be reeled and released, and then the length of the rubber hose is adjusted. The positioning plate is flipped to drive the rubber block to be inserted into the positioning hole to position the knob, so as to avoid the knob being accidentally touched and causing the stability of the rubber hose after the length is adjusted. The length adjustment by reeling reduces the wear rate of the rubber hose.

[0018] 2. The length-adjustable compression cuff has a magnetic force between magnet one and magnet two, so that the positioning plate can limit the knob and then fix it to the mounting block, thereby more stably preventing the knob from being accidentally touched and further improving the fixity of the rubber hose adjustment length.

[0024] like Figure 1-4 As shown, the utility model provides a technical solution: a length-adjustable compression cuff, comprising a mounting block 1, a rubber hose 2 is arranged inside the mounting block 1, the end of a handle 3 is fixedly connected to the top of the mounting block 1, an adjustment structure is arranged outside the rubber hose 2, the adjustment structure comprises a knob 4, a side wall of the mounting block 1 is provided with a knob 4, the end of the knob 4 is fixedly connected to one end of a rotating shaft 5, the other end of the rotating shaft 5 is fixedly connected to the side wall of a baffle 6, a connecting rope 7 is arranged outside the baffle 6, a positioning plate 8 is arranged outside the connecting rope 7, a groove 9 is arranged outside the positioning plate 8, a positioning hole 12 is arranged on the top of the groove 9, and the inner surface of the positioning hole 12 is matched with the outer surface of the rubber block 13.

[0025] In one embodiment of the utility model, one end of the connecting rope 7 is fixedly connected to the surface of the rotating shaft 5, and the other end of the connecting rope 7 is fixedly connected to the surface of the rubber hose 2. A groove 9 is provided on the side wall of the mounting block 1, and the inner wall of the groove 9 is hinged with the end of the positioning plate 8. A positioning hole 12 is provided at the end of the knob 4 away from the rotating shaft 5, and the end of the rubber block 13 is fixedly connected to the inner surface of the positioning plate 8. The end of the positioning plate 8 is fixedly connected to one side of the magnet 10, and the other side of the magnet 10 is magnetically connected to the side wall of the magnet 2 11, and the magnet 2 11 is located at the bottom of the knob 4. Two groups of grooves 9 are provided, and the two groups of grooves 9 are symmetrically arranged with the central axis of the positioning plate 8 as the symmetry axis, and the side of the magnet 2 11 away from the magnet 10 is fixedly connected to a group of grooves 9 located at the bottom of the knob 4.

[0026] In the utility model, when it is necessary to adjust the length of the rubber hose 2 during use, the knob 4 is manually rotated so that the knob 4 drives the rotating shaft 5 to rotate. After the rotating shaft 5 rotates, the connecting rope 7 is continuously reeled in. The pulling force of the connecting rope 7 causes the rubber hose 2 to be reeled in on the rotating shaft 5, thereby adjusting the length of the rubber hose 2. When the length is adjusted, the positioning plate 8 is flipped over so that the rubber block 13 on the positioning plate 8 is embedded in the interior of the positioning hole 12 to position the knob 4. When the rubber block 13 is completely embedded in the interior of the positioning hole 12, the positioning plate 8 drives the magnet 10 to be embedded in the interior of the groove 9. Finally, the magnetic attraction of the magnet 10 and the magnet 2 11 prevents the positioning plate 8 from being offset, thereby preventing the knob 4 from being accidentally touched and causing the stability of the rubber hose 2 after the length is adjusted.

[0027] The present invention is generally described in detail herein, but it is obvious to a person skilled in the art that some modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
