Description

Technical Field

[0001] The utility model relates to the technical field of war injury treatment, in particular to a one-key rotary pressure tourniquet. Background Art

[0002] A tourniquet is a simple and practical hemostatic tool, which is widely used in emergency treatment of trauma events, war injuries and daily life injuries. The inability to control bleeding in a timely and effective manner is the main cause of death for treatable trauma patients. The use of a tourniquet can achieve temporary hemostasis and can cope with the situation of relatively insufficient resources. War injuries are mainly firearm injuries, explosive shock injuries, etc. The analysis and research of a large number of preventable death cases show that these severe injuries often lead to limb artery injuries and severe bleeding, and then lead to death. Therefore, the tourniquet is recommended as the first-line treatment means for limb bleeding patients that cannot be controlled during battlefield first aid.

[0003] Currently, the most commonly used tourniquet for war injuries is the rotary pressure tourniquet. For example, in the invention patent application with the application publication number CN116439775A and the name of a rotary pressure tourniquet, it includes a tourniquet body, the tourniquet body is sleeved on the limb of the wounded, a winding rod and a fixing buckle are arranged on the tourniquet body, the middle part of the winding rod is fixedly connected with the tourniquet body, the fixing buckle is sleeved on the tourniquet body, and a fixing groove matching the end of the winding rod is opened thereon. A pressure sensor, a timer and a controller are also arranged on the tourniquet body, and a display is arranged on the exposed surface of the fixing buckle. The pressure sensor, the timer and the display are all electrically connected to the controller. The operation steps of the rotary pressure tourniquet are as follows: First, adjust the buckle to tighten the self-adhesive tape, and use the male hook and female loop of the magic tape to reversely stick the self-adhesive tape tightly. Then rotate the winding rod to tighten it. After the pressure is appropriate, insert the end of the winding rod into the fixing groove of the fixing buckle to fix it. In the prior art, the winding rod must be rotated to a position corresponding to the fixing groove of the fixing buckle to achieve fixation. In the actual use process, when the pressure of the tourniquet is appropriate, there is often a certain angle deviation between the rubber rod and the fixing groove. If it is rotated and tightened continuously, the pressure of the tourniquet will be too large. If it is rotated reversely and loosened, the pressure of the tourniquet will become smaller and cannot meet the hemostasis requirement. At the same time, the winding rod has a certain length, which often causes inconvenience to the patient's movement. Summary of the Utility Model

Detailed implementation manners

[0023] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] As Figures 1-5 shown, the present utility model provides a one-key rotary pressure tourniquet, which includes a tourniquet body that can be sleeved on the limb of a wounded person. The tourniquet body includes a fixed belt body 1 and a movable belt body 2. Side strips 12 are provided on opposite sides of the fixed belt body 1. The side strips 12 form a connection gap for the movable belt body 2 to pass through. A base 11 is provided on the fixed belt body 1. A rotary installation cavity 110 and a locking installation cavity 111 are provided on the base 11. A wire winding component 5 is rotatably installed in the rotary installation cavity 110. The wire winding component 5 includes a rotating part 51, a wire winding wheel 52, a rotation shaft 53, and a rotation button 54 that are coaxially arranged from bottom to top. Inlet holes 112 are provided on opposite sides of the rotary installation cavity 110. First wire bodies 21 and second wire bodies 22 are respectively provided on opposite sides of the movable belt body 2. The first wire bodies 21 and the second wire bodies 22 respectively enter the rotary installation cavity 110 through the two inlet holes 112 and are wound around the wire winding wheel 52. A rotation limiting component 3 is provided in the locking installation cavity 111. The rotation limiting component 3 is correspondingly arranged with the rotating part 51. The rotating part 51 is restricted by the rotation limiting component 3 and has a first state in which it can only rotate in the first direction and a second state in which it can only rotate in the second direction.

[0025] Specifically, the fixed belt body 1 and the movable belt body 2 cooperate with each other to form a tourniquet capable of stopping bleeding for the wounded. The width of the fixed belt body 1 is greater than that of the movable belt body 2. Side strips 12 are provided on the opposite sides of the fixed belt body 1. The side strips 12 are U-shaped. After the side strips 12 are fixed on the fixed belt body 1, a connecting gap with a rectangular cross-section is formed between the side strips 12 and the fixed belt body 1. The width of the connecting gap is consistent with the width of the movable belt body 2, so that the movable belt body 2 can pass through the connecting gap. A base 11 is fixedly arranged at the middle position of the fixed belt body 1. A rotating installation cavity 110 and a locking installation cavity 111 are arranged on the base 11. The rotating installation cavity 110 and the locking installation cavity 111 are communicated with each other. The rotating installation cavity 110 is used for installing the wire winding member 5, and the locking installation cavity 111 is used for installing the rotation limiting component 3. First wire bodies 21 and second wire bodies 22 are respectively arranged at both ends of the movable belt body 2. The first wire bodies 21 and the second wire bodies 22 are wound around the wire winding member 5 in the same direction. When the wire winding member 5 rotates in the first direction, the first wire bodies 21 and the second wire bodies 22 are gradually wound around the wire winding member 5, so that the movable belt body 2 is tightened, and the movable belt body 2 and the fixed belt body 1 are adjusted to an appropriate pressure to stop bleeding from the wound. On the contrary, when the wire winding member 5 rotates in the second direction, the first wire bodies 21 and the second wire bodies 22 are gradually loosened, and the movable belt body 2 and the fixed belt body 1 are loosened.

[0026] In this embodiment, the wire winding member 5 includes a rotating member 51, a wire winding wheel 52 and a rotating button 54 arranged coaxially. The rotating button 54 is circular. A rotating shaft 53 is arranged at the bottom of the rotating button 54. Both the wire winding wheel 52 and the rotating member 51 are installed on the rotating shaft 53. The rotating member 51 is located at the bottommost. The rotating shaft 53 is rotatably installed in the rotating installation cavity 110. Two wire inlet holes 112 are arranged on the side wall of the rotating installation cavity 110. The two wire inlet holes 112 are respectively arranged corresponding to both ends of the movable belt body 2. The first wire bodies 21 and the second wire bodies 22 can respectively enter the rotating installation cavity 110 from the two wire inlet holes 112 and are wound around the wire winding wheel 52 in the same direction. The locking installation cavity 111 is provided with a rotation limiting component 3. The rotation limiting component 3 is arranged corresponding to the rotating member 51. The rotation of the rotating member 51 can be limited through the rotation limiting component 3, so that the rotating member 51 has two rotation states, namely a first state and a second state. When the rotating member 51 is in the first state, at this time, the rotating member 51 can only rotate in the first direction, so that the movable belt body 2 is tightened. After the movable belt body 2 and the fixed belt body 1 are adjusted to an appropriate pressure, the fixed belt body 1 and the movable belt body 2 can be kept at an appropriate pressure. When the rotating member 51 is in the second state, at this time, the rotating member 51 can only rotate in the second direction, so that the movable belt body 2 can be loosened.

[0027] The one-key spinning tourniquet provided by the utility model includes a tourniquet body that can be sleeved on the limb of a wounded person. The tourniquet body includes a fixed strap 1 and a movable strap 2. A base 11 is provided on the fixed strap 1. A rotating installation cavity 110 and a locking installation cavity 111 are provided on the base 11. A winding member 5 is rotatably installed in the rotating installation cavity 110. The winding member 5 includes a rotating member 51, a winding wheel 52, a rotating shaft 53, and a rotating button 54 that are coaxially arranged from bottom to top. First wire bodies 21 and second wire bodies 22 are respectively arranged on opposite sides of the movable strap 2. The first wire bodies 21 and the second wire bodies 22 respectively enter the rotating installation cavity 110 through two wire inlet holes 112 and are wound around the winding wheel 52. A rotation limiting assembly 3 is provided in the locking installation cavity 111. The rotation limiting assembly 3 can limit the rotation directions of the winding wheel 52 and the rotating member 51. Thus, when in use, the movable strap 2 and the fixed strap 1 are sleeved on the limb of a patient. By rotating the rotating button 54, the winding wheel 52 and the rotating member 51 are rotated unidirectionally in a first rotation direction, so as to tighten the movable strap 2 and the fixed strap 1 until the tourniquet maintains an appropriate pressure on the wound part of the patient. When it is necessary to loosen the movable strap 2 and the fixed strap 1, the rotation limiting assembly 3 is adjusted so that the winding wheel 52 and the rotating member 51 can be rotated unidirectionally in a second rotation direction to realize the loosening of the movable strap 2 and the fixed strap 1. In this way, the operation is simple and an appropriate pressure can be maintained, which is suitable for the treatment of a patient's war injury.

[0028] In this embodiment, preferably, both the rotating installation cavity 110 and the locking installation cavity 111 are circular cavities. The rotating installation cavity 110 is communicated with the locking installation cavity 111. The height of the rotating installation cavity 110 is greater than the height of the locking installation cavity 111. A sealing plate 4 is provided at the top of the locking installation cavity 111, and the locking installation cavity 111 is sealed through the sealing plate 4.

[0029] In this embodiment, preferably, both the rotating member 51 and the winding wheel 52 are installed on the rotating shaft 53. The rotating member 51 includes a rotating ratchet installed at the bottom of the rotating shaft 53. The winding wheel 52 is located above the rotating ratchet. An annular groove is provided on the side wall of the winding wheel 52, and the first wire bodies 21 and the second wire bodies 22 are wound inside the annular groove.

[0030] In this embodiment, preferably, the rotation limiting assembly 3 includes a rotation adjusting member 37 and a first limiting member 31 and a second limiting member 32 disposed on opposite sides of the rotation adjusting member 37. Both the first limiting member 31 and the second limiting member 32 include a rotating end 33 and a limiting end 34. The rotating end 33 is rotatably mounted at one end of the locking mounting cavity 111 away from the rotation mounting cavity 110. A ratchet tooth 35 is provided on the limiting end 34. The first limiting member 31 and the second limiting member 32 are in a strip shape. The rotating ends 33 of the first limiting member 31 and the second limiting member 32 are rotatably mounted in the rotation mounting cavity 110 through a connecting shaft. The ratchet teeth 35 on the limiting end 34 can be two, or more. First arc-shaped pressing surfaces and second arc-shaped pressing surfaces are respectively provided on opposite sides of the limiting end 34 of the limiting member.

[0031] In this embodiment, preferably, the first limiting member 31 and the second limiting member 32 are mounted in the locking mounting cavity 111 in an inverted V shape. A spring member 36 is provided on one side of each of the first limiting member 31 and the second limiting member 32. The rotation adjusting member 37 includes a sector-shaped adjusting body 370. The sector-shaped adjusting body 370 includes two radial surfaces 372 and an arc-shaped limiting surface 371 disposed between the two radial surfaces 372. A rotation operation shaft 38 is provided on the sector-shaped adjusting body 370. A sealing plate 4 is provided on the locking mounting cavity 111. An installation hole for the rotation operation shaft 38 to pass through is provided on the sealing plate 4. The end of the rotation operation shaft 38 extends out from the installation hole and is connected with an operation button 39. The rotation operation shaft 38 can be driven to rotate through the operation button 39, so that the sector-shaped adjusting body 370 rotates. The sector-shaped adjusting body 370 is driven to rotate to have two working positions: a first working position and a second working position respectively, so that the first limiting member 31 and the second limiting member 32 both respectively have a first working state and a second working state.

[0032] The transmission and cooperation relationship among the sector adjusting body 370, the first limiting member 31 and the second limiting member 32 is as follows: when the arc limiting surface 371 of the sector adjusting body 370 corresponds to the first limiting member 31, the sector adjusting body 370 is in the first working position at this time. The first limiting member 31 is pressed and separated from the rotating ratchet wheel, and the spring member 36 connected to the first limiting member 31 is in a compressed state. At this time, the radial surface 372 of the sector adjusting body 370 corresponds to the second limiting member 32, and the spring member 36 connected to the second limiting member 32 is also in a compressed state. However, the ratchet teeth 35 at the end of the second limiting member 32 are engaged with the rotating ratchet wheel, that is, the first limiting member 31 is in the second working state, and the second limiting member 32 is in the first working state. At this time, when the winding wheel 52 and the rotating ratchet wheel rotate in the first direction (clockwise direction), the tooth groove of the rotating ratchet wheel first contacts the first arc pressing surface of the second limiting member 32, and the tooth groove of the rotating ratchet wheel applies a force perpendicular to the first arc pressing surface, so that the second limiting member 32 cannot rotate. In this way, the tooth groove of the rotating ratchet wheel is locked with the first arc pressing surface, and the rotating ratchet wheel cannot rotate in the first rotation direction. When the winding wheel 52 and the rotating ratchet wheel rotate in the second rotation direction (counterclockwise direction), the tooth groove of the rotating ratchet wheel first contacts the second arc pressing surface of the second limiting member 32, and the tooth groove of the rotating ratchet wheel applies a circumferential rotating force to the first arc pressing surface, so that the second limiting member 32 can be driven to rotate and press the spring member 36. After the second limiting member 32 rotates, it is separated from the rotating ratchet wheel, and the rotating ratchet wheel can rotate in the second rotation direction.

[0033] When the arc-shaped limiting surface 371 of the sector adjusting body 370 corresponds to the second limiting member 32, the second limiting member 32 is pressed against and separated from the rotating ratchet. At this time, the sector adjusting body 370 is in the second working position, and the spring member 36 connected to the second limiting member 32 is in a compressed state. At this time, the radial surface 372 of the sector adjusting body 370 corresponds to the first limiting member 31, and the spring member 36 connected to the first limiting member 31 is also in a compressed state. However, the ratchet teeth 35 at the end of the first limiting member 31 are engaged with the rotating ratchet, that is, the second limiting member 32 is in the second working state, and the first limiting member 31 is in the first working state. At this time, when the winding wheel 52 and the rotating ratchet rotate in the second rotation direction (counterclockwise), the tooth groove of the rotating ratchet first contacts the first arc-shaped pressing surface of the first limiting member 31, and the tooth groove of the rotating ratchet applies a force perpendicular to the first arc-shaped pressing surface, so that the second limiting member 32 cannot rotate, and the tooth groove of the rotating ratchet is locked with the first arc-shaped pressing surface, and the rotating ratchet cannot rotate in the second rotation direction. When the winding wheel 52 and the rotating ratchet rotate in the first rotation direction (clockwise), the tooth groove of the rotating ratchet first contacts the second arc-shaped pressing surface of the first limiting member 31, and the tooth groove of the rotating ratchet applies a circumferential rotating force to the second arc-shaped pressing surface, so that the first limiting member 31 can be driven to rotate and press against the spring member 36. After the first limiting member 31 rotates, it is separated from the rotating ratchet, and the rotating ratchet can rotate in the first rotation direction.

[0034] During use, according to the usage requirements, the rotating operation shaft 38 can be driven to rotate by operating the button 39, so that the sector adjusting body 370 rotates to limit the rotation of the winding wheel 52 and the rotating ratchet. For example, if it is necessary to tighten the movable belt body 2, the sector adjusting body 370 is rotated to the second working position. The arc-shaped limiting surface 371 of the sector adjusting body 370 corresponds to the second limiting member 32, and the radial surface 372 of the sector adjusting body 370 corresponds to the first limiting member 31. The second limiting member 32 is in the second working state, and the first limiting member 31 is in the first working state. The winding wheel 52 and the rotating ratchet can only rotate in the first rotation direction, that is, the movable belt body 2 can only be tightened and cannot be loosened. On the contrary, if it is necessary to loosen the movable belt body 2, the sector adjusting body 370 is rotated to the first working position. The arc-shaped limiting surface 371 of the sector adjusting body 370 corresponds to the first limiting member 31, and the radial surface 372 of the sector adjusting body 370 corresponds to the second limiting member 32. The first limiting member 31 is in the second working state, and the second limiting member 32 is in the first working state. The winding wheel 52 and the rotating ratchet can only rotate in the second rotation direction, that is, the movable belt body 2 can only be loosened and cannot be tightened.

[0035] In this embodiment, preferably, the movable belt body 2 includes a first belt body 23 and a second belt body 24 which are connected to each other. One end of the first belt body 23 is provided with a first wire body 21, the other end of the first belt body 23 is provided with a first connecting portion 25, one end of the second belt body 24 is provided with a second wire body 22, and the other end of the second belt body 24 is provided with a second connecting portion 26. The first connecting portion 25 and the second connecting portion 26 can be connected together to realize the connection between the first belt body 23 and the second belt body 24. The first connecting portion 25 and the second connecting portion 26 can be an adhesive structure capable of adhering to each other. For example, the first connecting portion 25 is a fuzzy surface of a magic tape, and the second connecting portion 26 is a hook surface of a magic tape. The first connecting portion 25 and the second connecting portion 26 can also be structures capable of engaging and fixing to each other. Through the first connecting portion 25 and the second connecting portion 26, the first belt body 23 and the second belt body 24 can be separated or connected. Thus, in the initial state, the first connecting portion 25 and the second connecting portion 26 are in a separated state, and both the first wire body 21 and the second wire body 22 are wound around the wire winding wheel 52. After the movable belt body 2 and the fixed belt body 1 are sleeved on the patient's limb, the first connecting portion 25 and the second connecting portion 26 are connected, so that the movable belt body 2 and the fixed belt body 1 form an annular belt body. Subsequently, according to the need, by rotating the rotary button 54, the wire winding wheel 52 and the rotary ratchet rotate to tighten the first wire body 21 and the second wire body 22 until the movable belt body 2 and the fixed belt body 1 maintain an appropriate pressure on the wound.

[0036] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
