Description

Technical Field

[0001] The present invention relates to the technical field of nursing devices, and specifically, to a surgical nursing tourniquet winding device and its method. Background Art

[0002] In surgical nursing, the winding of the tourniquet is a crucial step in controlling bleeding and ensuring a clear surgical field. Before the operation, the tourniquet needs to be carefully checked to ensure its proper functioning. When winding, the tourniquet should be tied to the part of the limb with rich muscles, such as the upper 1 / 3 of the upper arm in the upper limb and the groin near the thigh root in the lower limb, to avoid nerve injury. The tourniquet should be tied tightly enough to effectively stop bleeding without affecting blood circulation.

[0003] The patent with the application number CN202421221301.2 discloses a tourniquet winding device, including a unwinding box, an unwinding mechanism, a belt outlet tube, a guiding column, a belt fixing mechanism, a cutting mechanism, a tube cover and a box cover. A central column is arranged at the center inside the unwinding box, and the unwinding mechanism is movably connected inside the central column; when in use, through the opposite movement of two sliding blocks, under the action of the connecting rod, the supporting plate is propped outwards, and under the action of the two propped-up supporting plates, the inner support fixation of the tourniquet reel is realized, which can be applicable to the fixation of tourniquet reels of multiple specifications, and there is no need for medical staff to hold the tourniquet roll for winding, having better safety.

[0004] In surgical nursing, the traditional tourniquet binding operation (such as the cross-lock method) often requires the cooperation of two people: one medical staff needs to fix the patient's arm and lift the limb, and the other needs to wind and fix it at the proximal end. Although this method can effectively assist in vein exposure, in clinical applications, this method occupies a lot of nursing human resources, and it is easy to delay preoperative preparation in emergency surgeries or when there is a shortage of personnel. In addition, the differences in the operating habits of different medical staff may lead to unstable hemostatic effects.

[0005] In view of this, we propose a surgical nursing tourniquet winding device and its method. Summary of the Invention

[0006] The purpose of the present invention is to provide a surgical nursing tourniquet winding device and its method to solve the problems raised in the above background art.

[0007] To achieve the above purpose, on the one hand, the present invention provides the following technical solutions:

[0008] A surgical nursing tourniquet winding device, including an outer sleeve device, a driving device arranged on the outside of the outer sleeve device, and a placement device that moves with the movement of the driving device;

[0009] The outer jacket device includes a fixing part, rotating ring bodies arranged at the left and right ends of the fixing part, several clamping parts that change their own positions as the rotating ring bodies rotate, limiting bumps arranged on the inner side of the rotating ring bodies, and a second compression spring that pushes the limiting bumps to move outwards through its own elastic force;

[0010] The fixing part includes a fixing ring body, a pair of limiting ring bodies that limit the moving range of the driving device, and a ring-shaped rack arranged on the outer side of the fixing ring body. A cam groove is formed on the outer side wall of the fixing ring body;

[0011] The driving device includes a moving platform, a driving motor arranged on the top surface of the moving platform, a rotating shaft that rotates as the output shaft of the driving motor rotates, and shaft end gears arranged at both end parts of the rotating shaft. After the shaft end gears rotate, they abut against the ring-shaped rack, driving the moving platform and the placing device to perform circular motion on the outer side of the fixing part;

[0012] The placing device includes a moving slider that moves left and right reciprocally as the moving platform performs circular motion, a rod end pulley arranged below the moving slider, and a pair of placing rings used to limit the placing range of the tourniquet. When the rod end pulley moves with the moving platform, the contact position between itself and the cam groove constantly changes, driving the moving platform to move reciprocally, and simulating the artificial periodic change of the binding position of the tourniquet on the patient's arm.

[0013] In the technical solution of the present invention, the limiting ring body and the fixing ring body are integrally formed. A number of regularly distributed limiting sliding grooves are formed on the inner ring wall of the limiting ring body, and a number of regularly distributed limiting sliding holes are formed on the outer ring wall of the limiting ring body. The ring-shaped rack is welded and fixed on the outer ring wall of the fixing ring body.

[0014] In the technical solution of the present invention, the rotating ring body is rotatably connected to the outer side of the limiting ring body. An arc-shaped groove penetrating left and right is formed on the outer side wall of the rotating ring body. The outer ring wall of the rotating ring body is provided with ring wall through holes that have the same number, corresponding positions, and matching sizes as the limiting sliding holes.

[0015] In the technical solution of the present invention, the clamping part includes a limiting slider, an arc-shaped clamping block arranged on the inner side of the limiting slider, a limiting telescopic rod whose two ends are respectively clamped between the limiting slider and the arc-shaped clamping block, and a first compression spring sleeved on the outer side of the limiting telescopic rod.

[0016] In the technical solution of the present invention, an outer convex rod with an end extending to the outside of the arc groove is integrally formed on the outer wall of the limit slider. The elastic force provided by the first pressure spring pushes the arc clamping block to move inward. When the rotating ring body is turned to drive it to rotate, the contact position between the outer convex rod and the arc groove is changed, thereby driving the limit slider to move inward. After the arc clamping block contacts the patient's arm, the first pressure spring contracts to generate elastic force, thereby fixing the fixing part on the outside of the patient's arm.

[0017] In the technical solution of the present invention, the limiting protrusion is slidably connected to the inside of the limiting sliding hole, one end of the first pressure spring is adhered to the outer wall of the limiting protrusion, and the other end is adhered to the inner hole wall of the limiting sliding hole.

[0018] In the technical solution of the present invention, the moving platform is slidably connected between two limiting ring bodies and convex rods for limiting its movement are integrally formed at the corners of the outer wall of the moving platform. A table top groove that passes through the top and bottom is opened on the top surface of the moving platform, and a placement groove is opened on one side of the table top groove on the top surface of the moving platform. The top surface of the moving platform is provided with table body through grooves on both sides of the left and right sides of the placement groove. When in use, the top groove of the placement groove is fixedly connected to the placement plate by screws.

[0019] In the technical solution of the present invention, the outer side of the driving motor output shaft is fixedly connected to a worm gear via a bayonet, the left and right ends of the rotating shaft are respectively rotatably connected to the groove walls of the two table through grooves, and the outer side wall of the rotating shaft is fixedly connected to a worm meshing with the worm gear via a bayonet near the center position, and the shaft end gear is fixedly connected to the end position of the rotating shaft via a bayonet and meshes with the annular rack.

[0020] In the technical solution of the present invention, the movable slider is slidably connected to the inside of the groove on the table top, a rotating rod is rotatably connected to the bottom surface of the movable slider, the rod end pulley is clamped and fixed at the end position of the rotating rod, an extending rod is clamped and fixed on the outer wall of the movable slider, and the placement ring away from the movable slider can be disassembled from the extending rod to replace the tourniquet.

[0021] On the other hand, the present invention also provides a surgical care tourniquet winding method, using the above-mentioned surgical care tourniquet winding device, comprising the following steps:

[0022] S1. First, the operator lifts the patient's arm and puts the fixing part of the outer cover device on the outside of the patient's arm. In the subsequent operation, the operator always holds the patient's wrist and keeps the angle between the patient's arm and the bed;

[0023] S2, then, a pair of rotating ring bodies are moved to change the contact position between the outer convex rod in the clamping part and the arc-shaped groove wall, thereby driving the limit slider to move inward;

[0024] S3, after the arc-shaped clamping block contacts the arm, the limiting telescopic rod and the first pressure spring contract, and the elastic force generated by the contraction of the first pressure spring ensures the stability of the fixing part on the outside of the patient's arm;

[0025] S4. Subsequently, the operator guides the end of the tourniquet to the patient's arm, presses the end of the tourniquet against the patient's arm through a thin rod, and then starts the drive motor, which drives the worm gear to rotate through the output shaft;

[0026] S5, after the worm wheel rotates, it collides with the worm, and drives the rotating shaft to rotate, and then drives the shaft end gear to rotate accordingly, so that the shaft end gear collides with the annular rack, and the moving platform makes a circular motion outside the fixed ring body;

[0027] S6. When the moving platform makes a circular motion outside the fixed ring body, the contact position between the rod end pulley and the cam groove wall is constantly changing, thereby driving the moving slider to move back and forth left and right, thereby continuously pulling out the tourniquet placed in the ring, and allowing the tourniquet to be wrapped around the patient's arm.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. The surgical care tourniquet winding device and method thereof, by starting a driving motor, drives the moving platform and the placement device to move outside the fixed ring body, and by the movement of the rod end pulley in the cam groove, after the tourniquet in the placement ring is pulled out, the tourniquet is continuously wound around the outside of the patient's arm by simulating manual use of a cross-locking method, thereby reducing the occupation of human resources and the consistency of winding the tourniquet.

[0030] 2. The surgical care tourniquet winding device and method can drive the clamping part to change its position by turning the rotating ring body, so that the outer cover device as a whole can be quickly fixed on the outside of the patient's arm, thereby shortening the overall tourniquet winding time and avoiding delays in preoperative preparations.

[0045] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0046] Please refer to Figures 1-10 As shown, this embodiment provides a technical solution:

[0047] A surgical nursing tourniquet winding device includes an outer sleeve device 100, a driving device 200 arranged outside the outer sleeve device 100, and a placement device 300 that displaces as the driving device 200 moves.

[0048] In this embodiment, as Figures 2-4 shown, the outer sleeve device 100 includes a fixing part 110, rotating ring bodies 120 arranged at the left and right ends of the fixing part 110, several groups of clamping parts 130 that change their positions as the rotating ring bodies 120 rotate, a limiting convex block 140 arranged inside the rotating ring bodies 120, and a second pressure spring 150 that pushes the limiting convex block 140 to move outward through its own elastic force.

[0049] Specifically, the fixing part 110 includes a fixing ring body 111, a pair of limiting ring bodies 112 that limit the moving range of the driving device 200, and a ring-shaped rack 113 arranged on the outer side of the fixing ring body 111. A cam groove 1110 is opened on the outer side wall of the fixing ring body 111.

[0050] Furthermore, the limiting ring bodies 112 and the fixing ring body 111 are integrally formed. A number of regularly distributed limiting sliding grooves 1120 are opened on the inner ring wall of the limiting ring bodies 112, and a number of regularly distributed limiting sliding holes 1121 are opened on the outer ring wall of the limiting ring bodies 112. The ring-shaped rack 113 is welded and fixed on the outer ring wall of the fixing ring body 111.

[0051] Furthermore, the fixing ring body 111 is used to ensure the strength of the overall structure of the fixing part 110. The limiting ring bodies 112 are used to provide a rotating range for the rotating ring bodies 120. The limiting sliding grooves 1120 are used to provide a moving range for the clamping parts 130. The limiting sliding holes 1121 are used to provide a placement range for the limiting convex block 140 and the second pressure spring 150. The ring-shaped rack 113 is used to cooperate with the structure inside the driving device 200 so that the driving device 200 can move outside the fixing ring body 111.

[0052] In this embodiment, as Figures 5-6 shown, the rotating ring bodies 120 are rotatably connected to the outside of the limiting ring bodies 112. An arc-shaped groove 121 that penetrates left and right is opened on the outer side wall of the rotating ring bodies 120. Ring wall through holes 122 that are the same in number, corresponding in position one by one, and adapted in size to the limiting sliding holes 1121 are opened on the outer ring wall of the rotating ring bodies 120.

[0053] Specifically, the clamping part 130 includes a limiting slider 131, an arc-shaped clamping block 132 arranged inside the limiting slider 131, a limiting telescopic rod 133 whose two ends are respectively clamped between the limiting slider 131 and the arc-shaped clamping block 132, and a first pressure spring 134 sleeved outside the limiting telescopic rod 133.

[0054] Further, an outwardly protruding rod 1310 with an end extending to the outside of the arc-shaped groove 121 is integrally formed on the outer side wall of the limit slider 131. The elastic force provided by the first pressure spring 134 pushes the arc-shaped clamping block 132 to move inward. When the rotating ring body 120 is toggled to drive its rotation, by changing the contact position between the outwardly protruding rod 1310 and the arc-shaped groove 121, the limit slider 131 is driven to move inward. After the arc-shaped clamping block 132 contacts the patient's arm, the first pressure spring 134 contracts to generate an elastic force, thereby fixing the fixing portion 110 on the outer side of the patient's arm.

[0055] Further, by toggling a pair of rotating ring bodies 120, the contact position between the outwardly protruding rod 1310 and the groove wall of the arc-shaped groove 121 in the clamping portion 130 is changed, driving the limit slider 131 to move inward. After the arc-shaped clamping block 132 abuts against the arm, the limit telescopic rod 133 and the first pressure spring 134 contract. The elastic force generated by the contraction of the first pressure spring 134 ensures the stability of the fixing portion 110 on the outer side of the patient's arm, and the limit telescopic rod 133 limits the contraction range of the first pressure spring 134.

[0056] In this embodiment, as Figure 4 shown, the limit convex block 140 is slidably connected to the inside of the limit slide hole 1121. One end of the first pressure spring 134 is adhered to the outer side wall of the limit convex block 140, and the other end is adhered to the inner hole wall of the limit slide hole 1121.

[0057] Further, when the rotating ring body 120 rotates, after the limit convex block 140 abuts against the rotating ring body 120, it contracts into the inside of the limit slide hole 1121. During the continuous rotation of the rotating ring body 120, under the elastic force of the second pressure spring 150, the end extends to the outside of another ring wall through hole 122 again.

[0058] In this embodiment, as Figures 7-9 shown, the driving device 200 includes a moving table 210, a driving motor 220 arranged on the top surface of the moving table 210, a rotating shaft 230 that rotates as the output shaft of the driving motor 220 rotates, and shaft end gears 240 arranged at both end portions of the rotating shaft 230. After the shaft end gears 240 rotate, they abut against the annular rack 113, driving the moving table 210 and the placing device 300 to perform a circular motion outside the fixing portion 110.

[0059] Specifically, the mobile station 210 is slidably connected between two limiting ring bodies 112, and convex rods for limiting its movement are integrally formed at the corners of the outer side wall of the mobile station 210. A tabletop slot 211 that penetrates up and down is formed on the top surface of the mobile station 210, and a placement groove 212 is formed on one side of the tabletop slot 211 on the top surface of the mobile station 210. Table body through grooves 213 are formed on the left and right sides of the placement groove 212 on the top surface of the mobile station 210. During use, a placement plate is fixedly connected to the top slot opening of the placement groove 212 by screws.

[0060] Further, a worm gear 250 is fixedly connected to the outer side of the output shaft of the driving motor 220 through a pin. The left and right ends of the rotating shaft 230 are respectively rotatably connected to the groove walls of the two table body through grooves 213. A worm 260 meshing with the worm gear 250 is fixedly connected to the outer side wall of the rotating shaft 230 near the center position through a pin. The shaft end gear 240 is fixedly connected to the end position of the rotating shaft 230 through a pin and meshes with the annular rack 113.

[0061] Further, after the driving motor 220 is started, the worm gear 250 is driven to rotate through the output shaft. After contacting the worm 260, the rotating shaft 230 is driven to rotate, and then the shaft end gear 240 is driven to rotate accordingly. Thus, after the shaft end gear 240 contacts the annular rack 113, the mobile station 210 moves on the outside of the fixed ring body 111.

[0062] In this embodiment, as Figure 10 shown, the placement device 300 includes a moving slider 310 that moves left and right reciprocally as the mobile station 210 moves in a circular motion, a rod end pulley 330 disposed below the moving slider 310, and a pair of placement rings 350 for limiting the placement interval of the tourniquet. When the rod end pulley 330 moves with the mobile station 210, the contact position between itself and the cam groove 1110 continuously changes, driving the mobile station 210 to move reciprocally, and simulating the artificial periodic change of the binding position of the tourniquet on the patient's arm.

[0063] Specifically, the moving slider 310 is slidably connected inside the tabletop slot 211. A rotating rod 320 is rotatably connected to the bottom surface of the moving slider 310. The rod end pulley 330 is fixedly connected to the end position of the rotating rod 320. An extension rod 340 is fixedly connected to the outer side wall of the moving slider 310. The placement ring 350 far from the moving slider 310 can be disassembled from the extension rod 340 for replacing the tourniquet.

[0064] Further, during the process of the mobile station 210 making a circular motion outside the fixed ring body 111, the contact position between the rod-end pulley 330 and the groove wall of the cam groove 1110 continuously changes, driving the moving slider 310 to reciprocate left and right, and continuously pulling out the tourniquet in the placement ring 350, so that the tourniquet is wound around the patient's arm. A round rod for providing a rotation interval for the tourniquet is provided inside the placement ring 350, and the outer opening of the placement ring 350 is clamped with an outer cover that can be quickly disassembled and can observe the inside of the placement ring 350.

[0065] The present invention also provides a method for winding a surgical care tourniquet, using the above-mentioned surgical care tourniquet winding device, including the following steps:

[0066] S1. First, the operator raises the patient's arm and sleeved the fixing part 110 in the outer sleeve device 100 on the outside of the patient's arm. During subsequent operations, always hold the patient's wrist and keep an angle between the patient's arm and the hospital bed;

[0067] S2. Then, toggle a pair of rotating ring bodies 120, so that the contact position between the outer convex rod 1310 in the clamping part 130 and the groove wall of the arc groove 121 changes, driving the limit slider 131 to move inward;

[0068] S3. After the arc-shaped clamping block 132 abuts against the arm, the limit telescopic rod 133 and the first pressure spring 134 contract, and the elastic force generated by the contraction of the first pressure spring 134 ensures the stability of the fixing part 110 on the outside of the patient's arm;

[0069] S4. Subsequently, after the operator leads the end of the tourniquet to the patient's arm, press the end of the tourniquet on the patient's arm through the thin rod, and then start the driving motor 220, and drive the worm gear 250 to rotate through the output shaft;

[0070] S5. After the worm gear 250 rotates and abuts against the worm 260, drive the rotating shaft 230 to rotate, and then drive the shaft-end gear 240 to rotate accordingly. When the shaft-end gear 240 abuts against the annular rack 113, the mobile station 210 moves outside the fixed ring body 111;

[0071] S6. During the process of the mobile station 210 moving on the fixed ring body 111, the contact position between the rod-end pulley 330 and the groove wall of the cam groove 1110 continuously changes, driving the moving slider 310 to reciprocate left and right, and continuously pulling out the tourniquet in the placement ring 350, so that the tourniquet is wound around the patient's arm.

[0072] The foregoing description of the specific exemplary embodiments of the present invention is for purposes of illustration and exemplification. These descriptions are not intended to limit the invention to the precise forms disclosed, and it is apparent that many modifications and variations are possible in light of the above teaching. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the present invention and its practical applications, so that those skilled in the art can implement and utilize the various different exemplary embodiments of the present invention, as well as various different selections and modifications. The scope of the present invention is intended to be defined by the specification and its equivalents.
