Description

Technical Field

[0001] This invention relates to the field of pressure band technology, and more particularly to a pressure band. Background Technology

[0002] Currently, tourniquets are mainly used during venous blood sample collection and intravenous infusion to compress the veins at the elbow to slow venous blood reflux. The principle is to utilize the elastic force of the band to distribute pressure, transmitting pressure through the skin and tissue to compress superficial veins to a certain degree, forcibly closing the veins and preventing venous blood reflux. Tourniquets are typically used in conjunction with blood collection tubes, needles, and accessories during blood sample collection.

[0003] However, existing pressure bands have the following drawbacks:

[0004] (1) In the prior art, the pressure band is connected and fixed by Velcro or other means during use. When the patient’s muscles are tensed, the connection of the pressure band is easily unstable. Utility Model Content

[0005] In order to solve one or more technical problems existing in the prior art, the purpose of this application is to provide a pressure band that can make the connection of elastic binding bands more stable.

[0006] To address the aforementioned technical problems, one of the objectives of this application is achieved through the following technical solution:

[0007] A pressure band includes a mounting block, a mounting passage on the mounting block, and a through-hole on the mounting block located below the mounting passage. The mounting passage and the through-hole are both arranged on the left and right sides. A rack and pinion block is inserted into the mounting passage. An elastic binding rope is fixedly provided on the rack and pinion block. The elastic binding rope also passes through the through-hole. The mounting block is also provided with a winding and limiting component for limiting the rack and pinion block.

[0008] Furthermore, the winding limiting assembly includes a rotating rod that passes through the front side wall of the installation passage, a first gear that is fixedly sleeved on the rotating rod and meshes with the rack insert, and a turntable that is fixedly installed on the front side wall of the rotating rod.

[0009] Furthermore, several slots are evenly provided on the front side wall of the mounting block with the rotating rod as the center, and a pin that can be inserted into the slot is provided through the turntable. A stop bar is fixed on the pin bar, and a tightening spring sleeved on the pin bar is provided between the stop bar and the turntable.

[0010] Furthermore, several second gears are rotatably connected between the front and rear side walls of the installation passage, and the second gears can also mesh with the rack insert.

[0011] Furthermore, a tightening screw is screwed to the bottom of the through-hole, and the tightening screw tightens the elastic binding rope.

[0012] Furthermore, the elastic binding rope includes an elastic shape and a skin-friendly layer disposed on top of the elastic layer. The elastic layer is made of elastic fabric, and the skin-friendly layer is made of skin-friendly cotton fabric.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] (1) By setting a winding limit, the winding limit component and the rack insert are engaged, so that the two cooperate to limit each other, thereby making the connection of the elastic band more stable. Compared with the existing technology, it solves the technical problem that the band is easily unstable when the patient's muscles are tensed after the band is connected and fixed by Velcro or other means during use.

[0023] The terms "first," "second," etc., used in this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0024] Example 1:

[0025] like Figures 1-5 As shown, this embodiment provides a pressure band, which includes a mounting block 3, a mounting passage 5 opened on the mounting block 3, and a through-hole 6 opened on the mounting block 3 and located below the mounting passage 5. The mounting passage 5 and the through-hole 6 are both arranged on the left and right. A rack insert 4 is inserted into the mounting passage 5. An elastic binding rope 2 is fixed on the rack insert 4. The elastic binding rope 2 also passes through the through-hole 6. The mounting block 3 is also provided with a winding limiting component 1 for limiting the rack insert 4.

[0026] The compression bandage includes a mounting block 3 with a mounting passage 5 and a through-hole 6 located below the mounting passage 5. Both the mounting passage 5 and the through-hole 6 are positioned horizontally. A rack and pinion block 4 is inserted into the mounting passage 5, and an elastic binding rope 2 is fixed to the rack and pinion block 4, passing through the through-hole 6. A winding and limiting component 1 is also provided on the mounting block 3 to limit the movement of the rack and pinion block 4. By setting the winding and limiting component 1, the two engage with the rack and pinion block 4, allowing them to cooperate and limit the movement, thus making the connection of the elastic binding bandage more stable. Compared with existing technologies, this solves the technical problem that compression bandages connected and fixed using Velcro or similar methods are prone to instability when the patient's muscles tighten.

[0027] Furthermore, the winding limiting assembly 1 includes a rotating rod 8 that passes through the front side wall of the installation passage 5, a first gear 9 that is fixedly sleeved on the rotating rod 8 and meshes with the rack insert 4, and a turntable 12 that is fixedly installed on the front side wall of the rotating rod 8.

[0028] The winding limiting assembly 1 includes a rotating rod 8 that passes through the front wall of the mounting passage 5. A first gear 9, which meshes with a rack and pinion block 4, is fixedly sleeved on the rotating rod 8. A turntable 12 is fixedly mounted on the front wall of the rotating rod 8. Several slots 16 are evenly spaced on the front wall of the mounting block 3, centered on the rotating rod 8. A pin 13, which can be inserted into the slot 16, passes through the turntable 12. In use, the pin 13 is first pulled out of the slot 16. Then, the elastic strap is wrapped around the arm, and the rack and pinion block 4 is inserted into the mounting passage 5, meshing with the first gear 9. After the arm is tightly wrapped, the pin 13 is inserted into the corresponding slot 16, thus limiting the turntable 12 and the rotating rod 8 and preventing the rack and pinion block 4 from rotating freely, thereby making the connection of the elastic strap more stable.

[0029] Furthermore, a stop bar 14 is fixedly provided on the pin 13, and a tensioning spring 15 is provided between the stop bar 14 and the turntable 12 and sleeved on the pin 13. In this way, the elasticity of the tensioning spring 15 can be used to stably insert the pin 13 into the slot 16, preventing the pin 13 from being pulled out of the slot 16 at will.

[0030] Furthermore, several second gears 10 are rotatably connected between the front and rear side walls of the installation passage 5. The second gears 10 can also mesh with the rack and pinion block 4. In this way, the second gears 10 support the rack and pinion block 4, increase the point of force application of the rack and pinion block 4, and help improve practicality.

[0031] Furthermore, a tightening screw 7 is screwed to the bottom of the through-hole 6. The tightening screw 7 tightens the elastic binding rope 2. This method allows for adjustment of the tightness of the elastic binding strap and improves its applicability.

[0032] Furthermore, the elastic binding rope 2 includes an elastic layer 11 and a skin-friendly layer 17 disposed on top of the elastic layer 11. The elastic layer 11 is made of elastic fabric, which is a common and inexpensive elastic material and an ideal choice for making the bandage of the compression band. The skin-friendly layer 17 is made of skin-friendly cotton fabric, which is a Grade A fabric that comes into direct contact with the skin. After being brushed, the burrs on the fiber surface are greatly reduced, the flexibility is enhanced, and the comfort against the skin is good.

[0033] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
