Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a medical venous compression belt that is easy to wear and secure. Background Technology

[0002] Currently, when hospital nurses administer intravenous infusions or perform venous blood sampling, they need to use a knotted rubber tube to compress the patient's vein, fully exposing the blood vessel for easier needle insertion. For example, Chinese Patent Application No. CN201611044974.5 discloses a pressure band, which includes a buckle head and a rubber tube. The buckle head includes a base with an arc-shaped bottom surface; a snap-fit ​​part including a first snap, to which the rubber tube is detachably snapped; and a connection part where the rubber tube is fixedly connected. The opening of the first snap is adapted to the end of the rubber tube connected to the connection part, and the arc-shaped surface bends towards the opening of the first snap.

[0003] Because existing rubber tubes are too thin and slippery, and because the elasticity of the rubber tube makes knotting inconvenient and prone to loosening, and because the force is concentrated due to the thinness of the rubber tube, patients will feel pain and it will leave deep marks on the arm at the knot, increasing the patient's suffering. Therefore, we propose a medical venous compression band that is easy to wear and secure to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a medical venous compression band that is easy to wear and secure, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a medical venous compression band that is easy to wear and secure, comprising a rubber elastic band, with wear-resistant and non-slip fabric fixedly connected to both ends of one side of the rubber elastic band, and a fixing part fixedly connected to the other end of the rubber elastic band. A rectangular opening is provided on the side of the fixing part near the rubber elastic band, and a positioning strip is slidably engaged in the rectangular opening. One end of the positioning strip is fixedly connected to one end of a sliding rod, and the sliding rod is slidably sleeved on the fixing part, with an unlocking component slidably engaged at the other end of the sliding rod. The unlocking component is movably located at the end of the fixing part away from the rubber elastic band.

[0006] Preferably, the inner walls at both ends of the rectangular opening are respectively provided with guide grooves, and sliders are slidably engaged in the guide grooves, with the sliders respectively fixedly connected to both ends of the positioning strip.

[0007] Preferably, the end of the positioning strip away from the slide bar has a plurality of anti-slip teeth.

[0008] Preferably, the height of the rectangular opening is greater than the thickness of the rubber elastic band, and the opening length of the rectangular opening is greater than or equal to the width of the rubber elastic band.

[0009] Preferably, the slide bar has a recessed actuation port on one side.

[0010] Preferably, the unlocking assembly includes a toggle plate, a strong spring, a movable groove, a cylindrical pin, and a toggle block. The toggle block slides against the toggle opening (inside). One end of the toggle block is fixedly connected to one end of the toggle plate. The toggle plate is movably disposed in the movable groove, which is recessed at one end of the fixed part. The toggle plate has a zigzag structure, and cylindrical pins are fixedly connected to both ends of the toggle plate at the corners. The cylindrical pins are rotatably connected to the inner walls of both sides of the movable groove. One end of the strong spring is fixedly connected to the inner wall of the movable groove, and the other end of the strong spring is fixedly connected to the toggle plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by setting a wider rubber elastic band, the contact surface of the pressure position is increased, the force is more dispersed, and the pain is reduced. Through the lever action of the unlocking component, the sliding rod drives the positioning strip to always clamp the wear-resistant and anti-slip fabric, thereby clamping and fixing the rubber elastic band to prevent it from loosening.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1

[0018] Reference Figure 1 , 2This is the first embodiment of the present invention. This embodiment provides a medical venous compression band that is easy to wear and secure. It includes a rubber elastic band 1. Wear-resistant and non-slip fabric 2 is fixedly connected to both ends of one side of the rubber elastic band 1. A fixing part 3 is fixedly connected to the other end of the rubber elastic band 1. A rectangular opening 4 is opened on the side of the fixing part 3 near the rubber elastic band 1. A positioning strip 5 is slidably engaged in the rectangular opening 4. One end of the positioning strip 5 is fixedly connected to one end of a sliding rod 6. The sliding rod 6 is slidably sleeved on the fixing part 3, and the other end of the sliding rod 6 is slidably engaged with an unlocking component 7. The unlocking component 7 is movably disposed at the end of the fixing part 3 away from the rubber elastic band 1.

[0019] The rubber elastic band 1 adopts a rectangular strip structure. The wider rubber elastic band 1 increases the contact surface at the compression point, making the force more dispersed and reducing pain. The rubber elastic band 1 is tied to the position requiring compression. Medical staff manually press the unlocking component 7 to move the slide bar 6. The slide bar 6 moves the fixed positioning bar 5, thus exposing the rectangular opening 4, which allows the rubber elastic band 1 and the wear-resistant and anti-slip fabric 2 to pass through. One side of the wear-resistant and anti-slip fabric 2 (such as rubber cloth) fixed to the rubber elastic band 1 passes through the rectangular opening 4, and the rubber elastic band 1 is located between the positioning bar 5 and the inner wall of the rectangular opening 4, so that the rubber elastic band 1 forms a ring structure tied to the outside of the limb being compressed. Then, the end of the rubber elastic band 1 is pulled to tighten the rubber elastic band 1. After tightening, the unlocking component 7 is released, and the slide bar 6 moves in the opposite direction in conjunction with the lever principle. The slide bar 6 then moves the positioning bar 5 to clamp and fix the rubber elastic band 1 in conjunction with the rectangular opening 4, preventing the rubber elastic band 1 from loosening.

[0020] Example 2

[0021] Reference Figure 1-3 This is the second embodiment of the present invention, which is based on the previous embodiment. Specifically, the inner walls of both ends of the rectangular opening 4 are respectively provided with guide grooves 41, and sliders 52 are slidably engaged in the guide grooves 41. The sliders 52 are respectively fixedly connected to both ends of the positioning strip 5. The sliding cooperation between the guide grooves 41 and the sliders 52 ensures that the positioning strip 5 only achieves reciprocating linear movement, preventing the positioning strip 5 from deviating.

[0022] Specifically, the end of the positioning strip 5 away from the slide bar 6 is provided with several anti-slip teeth 51. The anti-slip teeth 51 improve the friction of the clamping position and further ensure the stability of the clamping.

[0023] Specifically, the height of the rectangular opening 4 is greater than the thickness of the rubber elastic band 1, and the opening length of the rectangular opening 4 is greater than or equal to the width of the rubber elastic band 1, so that the rubber elastic band 1 can pass through the rectangular opening 4.

[0024] Specifically, a toggle opening 61 is recessed on one side of the slide bar 6.

[0025] Specifically, the unlocking component 7 includes a toggle plate 71, a strong spring 72, a movable groove 73, a cylindrical pin 74, and a toggle block 75. The toggle block 75 slides against the toggle opening 61. One end of the toggle block 75 is fixedly connected to one end of the toggle plate 71. The toggle plate 71 is movably disposed in the movable groove 73. The movable groove 73 is recessed at one end of the fixed part 3. The toggle plate 71 has a zigzag structure, and the two ends of the toggle plate 71 at the corners are respectively fixedly connected to the cylindrical pin 74. The cylindrical pin 74 is rotatably connected to the inner walls of both sides of the movable groove 73. One end of the strong spring 72 is fixedly connected to the inner wall of the movable groove 73, and the other end of the strong spring 72 is fixedly connected to the toggle plate 71.

[0026] Medical staff manually press the toggle plate 71 of the unlocking component 7. The toggle plate 71 moves the toggle block 75 through the lever principle. At the same time, the toggle plate 71 compresses the strong spring 72. The toggle block 75 moves the slide bar 6. The slide bar 6 moves the fixed positioning strip 5, thus exposing the rectangular opening 4, which facilitates the passage of the rubber elastic band 1 and the wear-resistant and non-slip fabric 2. After passage, the toggle plate 71 of the unlocking component 7 is released. Under the elastic force of the strong spring 72, the toggle plate 71 moves the slide bar 6 in the opposite direction in conjunction with the lever principle. The slide bar 6 then moves the positioning strip 5 to clamp and fix the rubber elastic band 1 in conjunction with the rectangular opening 4.

[0027] Example 3

[0028] Reference Figure 1-3 This is the third embodiment of the present invention. Based on the previous two embodiments, in use, the rubber elastic band 1 adopts a rectangular strip structure. The rubber elastic band 1 is tied to the position requiring compression. Medical personnel manually press the actuating plate 71 of the unlocking component 7. The actuating plate 71 moves the actuating block 75 via a lever principle. Simultaneously, the actuating plate 71 compresses the strong spring 72. The actuating block 75 moves the sliding rod 6, which in turn moves the fixed positioning strip 5, thus exposing the rectangular opening 4, allowing the rubber elastic band 1 and the wear-resistant, non-slip fabric 2 to pass through. The rubber elastic band 1 is fixedly installed... Some wear-resistant and anti-slip fabric 2 (such as rubber fabric) passes through the rectangular opening 4, and the rubber elastic band 1 is located between the positioning strip 5 and the inner wall of the rectangular opening 4, so that the rubber elastic band 1 forms a ring structure and is tied to the outside of the compressed limb. Then, pull the end of the rubber elastic band 1 to tighten the rubber elastic band 1. After tightening, release the toggle plate 71 of the unlocking component 7. Under the elastic force of the strong spring 72, the toggle plate 71 drives the slide bar 6 to move in the opposite direction in conjunction with the lever principle. The slide bar 6 then drives the positioning strip 5 to clamp and fix the rubber elastic band 1 in conjunction with the rectangular opening 4 to prevent the rubber elastic band 1 from loosening.

[0029] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial improvements made to this utility model using this concept should be considered as infringing on the protection scope of this utility model.
