Description

Technical Field

[0001] The invention belongs to the technical field of tourniquets, in particular to a rotary tourniquet. Background Art

[0002] The rotary tourniquet is a commonly used medical device that plays an important role in stopping bleeding. By applying external pressure, the tourniquet is passed around the bleeding site and tightly rotated. The powerful contraction force generated by the rotary rod utilizes the tightening principle, effectively compressing the blood vessels, reducing bleeding, and achieving a hemostatic effect.

[0003] Some existing rotary tourniquets need to be loosened at intervals, and then the rotary rod is rotated again to tighten the tourniquet. Manual tightening of the tourniquet is prone to detachment from the rotary rod, causing the tourniquet to loosen abnormally, which consumes a lot of time. In addition, the tourniquet becomes thinner when tightened, which puts greater pressure on the skin. The rotary rod is stuck in the slot, and the slot is large, so the rotary rod may rotate, causing the tourniquet to loosen slightly due to the rotation, thereby affecting the tightening and hemostasis effect on the wound.

Detailed implementation manners

[0044] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0045] Embodiment 1

[0046] Please refer to Figure 1 - Figure 7 This application provides a spinning tourniquet, including:

[0047] The spinning box 101 has two wound tourniquets 100 symmetrically arranged on both sides. Fixed buckles 103 are provided on both sides of the spinning box 101. The upper ends of the two wound tourniquets 100 are respectively wound around the two fixed buckles 103. The wound tourniquet 100 and the fixed buckle 103 are detachable. A cotton pad can be provided on the inner surface of the spinning box 101;

[0048] Inner hoses 104 are respectively embedded and installed on the inner surface of the wound tourniquet 100. The winding of the inner hoses 104 drives the wound tourniquet 100 to tighten. The upper ends of the two inner hoses 104 extend into the spinning box 101;

[0049] The winding member 200 installed inside the spinning box 101 and winding the upper ends of the two inner hoses 104. By providing the winding member 200, the two inner hoses 104 can be automatically tightened to tighten the limb part of the patient for hemostasis. Compared with manually rotating the spinning rod, the situation that the tourniquet is abnormally loosened due to detachment from the spinning rod will not occur. The winding member 200 includes a rotating shaft 202 vertically installed inside the spinning box 101. A plurality of bow-shaped rods 206 for winding the upper ends of the inner hoses 104 are provided on the circumferential surface of the rotating shaft 202. The plurality of bow-shaped rods 206 form a circular winding structure with a larger diameter, so that the inner hose 104 will not bend greatly during the winding process, reducing the generation of creases and facilitating subsequent inflation use;

[0050] The inflation member 500 connected to the winding member 200 and inflating the inner hose 104. By providing the inflation member 500, inflation can be carried out inside while the inner hose 104 is tightened, so that the inner hose 104 expands, further expanding the tightening effect on the patient's limb, and the situation of long-term relaxation of the tourniquet will not occur. Moreover, the diameter of the inflated inner hose 104 becomes larger, reducing the indentation marks. The inflation member 500 includes inflation cylinders 503 located on both sides of the rotating shaft 202. A piston plate 504 is provided at the middle position inside the inflation cylinder 503. The outer ring of the piston plate 504 is a rubber ring, which is convenient for sealing. A piston rod 507 is provided inside the piston plate 504. The piston rod 507 penetrates through the inflation cylinder 503 and is exposed outside. And a corrugated pipe can be provided between the piston rod 507 and the outer side surface of the inflation cylinder 503 to play a sealing role and maintain the pressure inside the inflation cylinder 503. An inflation pipe 505 is provided between the outer end of the inflation cylinder 503 and the lower end of the inner hose 104. The rotation of the rotating shaft 202 drives the movement of two transverse racks 502 connected to the piston rod 507.

[0051] In this embodiment, preferably, the winding member 200 further includes:

[0052] An installation cylinder 204 sleeved on the rotating shaft 202. A plurality of bow-shaped rods 206 are circumferentially distributed on the installation cylinder 204 and can rotate synchronously with the installation cylinder 204, which is convenient for winding the inner hose 104 around the bow-shaped rods 206;

[0053] A limiting circular plate 203 is provided at the lower end of the installation cylinder 204. The diameter of the limiting circular plate 203 is larger than the diameter of the circular structure formed by the plurality of bow-shaped rods 206, which plays a role in limiting the wound inner hose 104. Spiral joints 205 are provided on two symmetrically distributed bow-shaped rods 206. The upper ends of the two inner hoses 104 cross through the bottom of the spinning box 101 and are respectively connected to the two spiral joints 205. The cross distribution of the two inner hoses 104 facilitates tightening and better stops bleeding of the patient's limb. The spiral joint 205 plays a sealing role at the end of the inner hose 104;

[0054] A micro motor 201 installed on the inner wall of the upper end of the spinning box 101 and connected to the rotating shaft 202 can drive the rotating shaft 202 to rotate.

[0055] In this embodiment, preferably, the inflating member 500 for inflating the inner hose 104 further includes:

[0056] A gear ring 501 sleeved on the upper end of the installation cylinder 204. Transverse racks 502 are respectively horizontally located in front of and behind the gear ring 501. As the gear ring 501 rotates, it can drive the two transverse racks 502 to rotate away from or towards each other, and the transverse racks 502 are meshed and connected to the gear ring 501;

[0057] A piston rod 507 installed at the inner end of the transverse rack 502. The other end of the piston rod 507 is fixed to the inner side surface of the piston plate 504. As the transverse rack 502 moves, it can drive the piston rod 507 and the piston plate 504 to move, and the movement of the piston plate 504 changes the size of the internal space of the inflating cylinder 503.

[0058] In this embodiment, preferably, the piston plate 504 divides the internal space of the inflating cylinder 503 into an outer air chamber 508 and an inner air chamber 509. The size of the inflating cylinder 503 can be set according to actual production requirements. The upper end of the inflating pipe 505 is communicated with the inner air chamber 509. The lower end of the inner hose 104 is connected to a spiral cylinder 105 embedded in the inner surface of the lower end of the winding tourniquet 100. The lower end of the inflating pipe 505 is communicated with the spiral cylinder 105. The gas flowing inside the inflating pipe 505 can enter the spiral cylinder 105 and enter the inner hose 104 through the spiral cylinder 105.

[0059] In summary, when in use, the upper end of the winding tourniquet 100 is wound around the fixed buckle 103. The winding tourniquet 100 is sleeved on the patient's limb at a certain distance from the wound. The lower end of the winding tourniquet 100 is snap-connected, and the winding tourniquet 100 is fixedly sleeved on the patient's limb. The micro motor 201 works to drive the rotating shaft 202 to rotate, driving the installation cylinder 204 and the bow-shaped rod 206 to rotate, driving the upper ends of the two inner hoses 104 to rotate and wind around the bow-shaped rod 206. The inner hose 104 gradually tightens the patient's limb as it is wound up, tightening the patient's limb to stop bleeding. And while the rotating shaft 202 rotates, it will drive the gear ring 501 to rotate, and the two transverse racks 502 meshing with it move away from each other, driving the two piston rods 507 to move away from each other at the same time, driving the piston plate 504 to move. The space of the outer air chamber 508 gradually becomes larger, and the space of the inner air chamber 509 gradually becomes smaller. The piston plate 504 squeezes the gas in the inner air chamber 509 outwards and sends the gas into the charging pipe 505, and enters the spiral cylinder 105 through the charging pipe 505, and is sent into the inner hose 104 through the spiral cylinder 105. The inner hose 104 gradually expands, further increasing the tightening effect on the limb, and expanding the contact area with the patient's limb, reducing the indentation. When the tightening degree of the inner hose 104 is appropriate, the micro motor 201 stops working, maintaining the situation that the two inner hoses 104 always tighten the limb, improving the hemostatic effect on the patient.

[0060] Embodiment 2

[0061] Refer to Figure 7 and Figure 8 , which is the second embodiment of the present invention.

[0062] In this embodiment, preferably, a hemostatic member 400 for temporarily pressing and stopping bleeding of the wound is connected to the rear side of the winding tourniquet 100. By using the hemostatic member 400, when the patient's limb is loosened from hemostasis, the pressing airbag 401 can be inflated to temporarily press and stop bleeding of the patient's wound, reducing the situation of blood overflow from the wound. And the inflation pressing hemostasis will not have uneven force on the pressed part compared with manual pressing, and the pressing effect is better. The hemostatic member 400 includes:

[0063] A pressing airbag 401 for pressing the wound. Pressing belts 402 are arranged on both sides of the pressing airbag 401. The pressing belts 402 are detachable from the pressing airbag 401, and a medical cotton is detachably arranged on the lower surface of the pressing airbag 401;

[0064] Two connecting hoses 506 communicating with the top of the pressing airbag 401. The front ends of the two connecting hoses 506 are respectively connected to two inflating cylinders 503, and the connecting hoses 506 are communicated with the outer air chamber 508. The inflating cylinders 503 can be used to inflate the pressing airbag 401, and the pressing airbag 401 expands to press the wound. The medical cotton presses and stops bleeding of the wound;

[0065] The filling hose 403 is embedded in the inner surface of the compression belt 402. The gas in the compression airbag 401 can enter the filling hose 403, thereby increasing the tightening effect on the skin around the patient's wound and preventing the compression belt 402 from moving away from the wound.

[0066] In this embodiment, preferably, the upper end of the filling hose 403 is connected to the bottom of the compression airbag 401, and rectangular frames are provided on both sides of the compression airbag 401. The upper end of the compression belt 402 is wrapped around the rectangular frame, and Velcro is provided on the upper end surface of the compression belt 402 to facilitate the compression belt 402 to be wrapped and fixed on the rectangular frame, and to facilitate the disassembly of the compression belt 402 and the winding length can also be adjusted.

[0067] In summary, when in use, the compression airbag 401 and the medical cotton cover the patient's wound, the compression belt 402 is sleeved on the patient's limb and the upper end passes through the rectangular frame and is self-adhesive and fixed. At this time, the compression airbag 401 is in a contracted state, and the wrapped tourniquet 100 and the inner hose 104 are in a tightened state to stop bleeding on the patient's limb. When it is necessary to loosen the wrapped tourniquet 100 on the patient's limb, the micro motor 201 works, driving the rotating shaft 202 to rotate in the opposite direction, driving the mounting cylinder 204 and the bow rod 206 to rotate in the opposite direction, so that the wrapped inner hose 104 is loosened and the tightening effect on the patient's limb is removed. The reverse rotation of the mounting cylinder 204 drives the two horizontal racks 502 to rotate relative to each other, and the space of the outer air cavity 508 gradually becomes smaller, while the inner air cavity 508 is gradually reduced. The cavity 509 gradually becomes larger, and the space of the inner air cavity 509 becomes larger to suck the gas in the inner hose 104. The inner hose 104 does not expand, reducing the tightening effect on the patient's limbs. At the same time, the outer air cavity 508 becomes smaller to squeeze the internal gas, and the squeezed gas enters the connecting hose 506 and enters the compression airbag 401. The expansion of the compression airbag 401 drives the medical cotton to press the wound evenly to temporarily stop bleeding. At the same time, the gas in the compression airbag 401 enters the filling hose 403, and the filling hose 403 expands, increasing the pressing and stopping bleeding effect of the entire compression airbag 401 and the compression belt 402 on the patient's wound, and increasing the friction resistance between the patient's limbs, making it less likely that the compression belt 402 and the compression airbag 401 will separate from the wound.

As the first mounting plate 301 and the second mounting plate 302 continue to approach, until the end of the movable wedge 305 is completely located outside the fixed wedge 304, without the restriction of the fixed wedge 304, the return spring resets to drive the movable wedge 305 to move forward, and the plane of the movable wedge 305 contacts the plane of the fixed wedge 304, so that the two will not separate from each other without manual operation, realizing the detachable use of the winding tourniquet 100.
