DETAILED DESCRIPTION

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0029] Example 1 Reference Figure 1 and Figure 2 , which is the first embodiment of the present invention, provides a medical wrist band with a hemostatic function. The medical wrist band with a hemostatic function includes a main component 100, including a wrist band body 101, an information nameplate 102 is fixed on one side of the wrist band body 101, and the wrist band body 101 is made of an elastic strap.

[0030] The information nameplate 102 records the patient's identity information. When the wrist band body 101 is worn on the patient's wrist, medical staff can identify the patient's identity information through the information nameplate 102. This is existing technology and this solution will not be elaborated on. By making the wrist band body 101 with an elastic strap material, the wrist band body 101 can have a certain hardness and elasticity. In an emergency, when it is necessary to stop bleeding for the patient, the wrist band body 101 can be tied near the bleeding site and tightened to achieve a hemostatic effect, thereby avoiding medical staff or rescuers spending extra time looking for hemostatic tools, thereby delaying the best time to stop bleeding and increasing the risk of excessive blood loss for the patient.

[0031] The locking assembly 200 is provided on the wrist band body 101 and includes a rotating part 201. The rotating part 201 includes a fixed frame 201a. The fixed frame 201a is fixed to one end of the wrist band body 101, and the other end of the wrist band body 101 is inserted into the fixed frame 201a. A rotating column 201b is rotatably connected in the fixed frame 201a. One end of the wrist band body 101 is wrapped around the outside of the rotating column 201b, and the end is fixed to the rotating column 201b.

[0032] The side of the fixing frame 201a close to the patient is soft, which can improve the comfort when wearing. When the wrist band body 101 is worn on the patient's wrist, the excess length of the wrist band body 101 can be rolled up on the outside of the rotating column 201b, so as to avoid the length of the wrist band body 101 being too long, which will hinder the patient's normal movement. The tightness of the wrist band body 101 can also be adjusted by rotating the rotating column 201b. When it is necessary to stop bleeding at the bleeding site, the wrist band body 101 can be tightened by the rotating column 201b, which can stop bleeding at the bleeding site.

[0033] Example 2 Reference Figure 2-Figure 7 , which is the second embodiment of the present invention, and is based on the previous embodiment.

[0034] Specifically, the locking assembly 200 also includes a locking member 202, which includes a support frame 202a, which is fixed to the inner top wall of the fixed frame 201a, a locking block 202b is provided in the support frame 202a, a locking hole 201b-1 is provided on the rotating column 201b, the locking block 202b is engaged with the locking hole 201b-1, a first spring 202c is fixed to one side of the locking block 202b, and the other end of the first spring 202c is fixed to the inner wall of the support frame 202a.

[0035] One side of the locking block 202b is inclined, and there are multiple locking holes 201b-1, which are evenly distributed in a ring shape on the outside of the rotating column 201b. The locking block 202b cooperates with the locking holes 201b-1 to limit the rotation direction of the rotating column 201b, so that it can only rotate in the direction of tightening the wrist band body 101, and cannot rotate in the opposite direction, thereby preventing the wrist band body 101 from loosening after tightening.

[0036] The support frame 202a is used to support the locking block 202b, and the first spring 202c is used to apply a thrust to the locking block 202b so that the locking block 202b is more tightly engaged with the locking hole 201b-1.

[0037] Specifically, the locking assembly 200 also includes a pushing member 203, which includes a force-bearing rod 203a, which is fixed to the bottom of the locking block 202b, a gear 203b is provided below the force-bearing rod 203a, and a push rod 203c is fixed to the top of the gear 203b, the push rod 203c corresponds to the force-bearing rod 203a, the force-bearing rod 203a is Z-shaped, and the gear 203b is lower than the height of the force-bearing rod 203a.

[0038] When the wrist band body 101 stops the bleeding at the patient's bleeding site for a sufficient time, the gear 203b rotates just one circle and drives the push rod 203c to contact the force-bearing rod 203a. The push rod 203c pushes the force-bearing rod 203a to move, and drives the locking block 202b to separate from the lock hole 201b-1 through the force-bearing rod 203a, thereby releasing the restriction on the rotating column 201b. At this time, the wrist band body 101 can relax the locking force on the patient, thereby temporarily restoring blood circulation in the distal limbs and avoiding serious damage to limb tissues due to prolonged ischemia, such as muscle necrosis, nerve damage, etc.

[0039] Specifically, the locking assembly 200 also includes a rotating member 204, which includes a fixed box 204a. The fixed box 204a is located in the fixed frame 201a. A coil spring 204b is provided in the fixed box 204a. A rotating sleeve 204c is fixed in the coil spring 204b. The rotating sleeve 204c is sleeved on the outside of the rotating column 201b. A tooth block 204d is provided on one side of the rotating sleeve 204c. The gear 203b is rotatably connected to the top of the fixed box 204a through a rotating shaft.

[0040] The fixing box 204a is used to install the coil spring 204b. When the wrist band body 101 is tightened to the appropriate force on the patient, the rotating sleeve 204c is rotated and the coil spring 204b is tightened. When the coil spring 204b rotates in the direction of relaxation, it will drive the rotating sleeve 204c to rotate. At this time, the rotation direction of the rotating sleeve 204c is consistent with the direction of tightening the wrist band body 101. At the same time, the rotating sleeve 204c will drive the gear 203b to rotate through the tooth block 204d. After the coil spring 204b rotates in the direction of relaxation for a certain period of time, the wrist band body 101 will stop the bleeding at the patient's bleeding site for enough time. At this time, the rotating sleeve 204c will drive the gear 203b to rotate one circle through the tooth block 204d, so that the gear 203b can drive the push rod 203c to push the force-bearing rod 203a to move.

[0041] Specifically, a winding wheel 204e is fixed to the outside of the rotating sleeve 204c, and a pull rope 204f is wound around the outside of the winding wheel 204e. One end of the pull rope 204f is fixed to the winding wheel 204e, and the other end passes through the outside of the fixed frame 201a and is fixed with a handle 204g.

[0042] When the wristband body 101 is tied to the bleeding part of the patient and tightened with a certain force, the medical staff pulls the handle 204g to drive the pull rope 204f to move, so that the pull rope 204f drives the reel 204e and the rotating sleeve 204c to rotate, so that the rotating sleeve 204c can tighten the coil spring 204b.

[0043] Specifically, a positioning block 204d-1 is fixed on one side of the rotating sleeve 204c, a positioning shaft 204d-2 is fixed on the tooth block 204d, a torsion spring 204d-3 is fixed on the top of the positioning block 204d-1, and the other end of the torsion spring 204d-3 is fixed to the positioning shaft 204d-2, and a stop block 204d-4 is fixed on one side of the rotating sleeve 204c, and the stop block 204d-4 is in contact with one side of the tooth block 204d.

[0044] The positioning block 204d-1 cooperates with the positioning shaft 204d-2 to support and position the tooth block 204d. The stop block 204d-4 is set to limit the rotation direction of the tooth block 204d. When the rotating sleeve 204c rotates in the direction of tightening the coil spring 204b, the engagement between the tooth block 204d and the gear 203b will not drive the gear 203b to rotate. Only when the coil spring 204b drives the rotating sleeve 204c to rotate, the engagement between the tooth block 204d and the gear 203b will drive the gear 203b to rotate. The torsion spring 204d-3 is used to reset the rotated tooth block 204d.

[0045] Example 3 Reference Figures 1-9 , which is the third embodiment of the present invention, is based on the first two embodiments.

[0046] Specifically, the locking assembly 200 also includes a connecting member 205, which includes a fixed sleeve 205a, which is fixed to one side of the rotating sleeve 204c. An insertion rod 205b is provided in the fixed sleeve 205a, and a socket 201b-2 is provided on the rotating column 201b. The insertion rod 205b corresponds to the socket 201b-2, and a second spring 205c is fixed to one end of the insertion rod 205b.

[0047] When the locking block 202b is separated from the locking hole 201b-1, and the wrist band body 101 can relax the locking force on the patient, after the wrist band body 101 is relaxed for a short time, as the rotating sleeve 204c rotates, the insertion rod 205b will release the restriction, and the second spring 205c will push the insertion rod 205b to move, so that the insertion rod 205b is engaged with the hole 201b-2. Through the cooperation of the two, the rotating sleeve 204c can be connected to the rotating column 201b, so that the rotating sleeve 204c can drive the rotating column 201b to rotate when it rotates, so that the wrist band body 101 can be automatically tightened again by the rotating column 201b, thereby avoiding the situation where the wrist band body 101 is relaxed for too long, which will cause the bleeding site to bleed severely again, and when the wrist band body 101 is tightened again, the tightness of the wrist band body 101 can be adjusted by rotating the rotating column 201b.

[0048] There are multiple sockets 201b-2, which are evenly distributed in a ring shape on the outside of the rotating column 201b. Through the arrangement of multiple sockets 201b-2, the insertion rod 205b can be engaged with the socket 201b-2 as soon as the restriction is released.

[0049] Specifically, a groove 205b-1 is provided on the insertion rod 205b, a limiting column 205d is provided in the groove 205b-1, a third spring 205e is fixed to the bottom end of the limiting column 205d, a connecting column 205f is fixed to one side of the force-bearing rod 203a, and an extrusion block 205g is fixed to the bottom end of the connecting column 205f.

[0050] A limiting hole is provided on the fixing sleeve 205a, and the limiting column 205d engages with the limiting hole. The cooperation between the two can restrict the insertion rod 205b, so that the insertion rod 205b cannot engage with the insertion hole 201b-2. The top of the limiting column 205d is arc-shaped, and the connecting column 205f is L-shaped.

[0051] When the locking block 202b is separated from the locking hole 201b-1, the locking block 202b will drive the squeezing block 205g to move through the connecting column 205f, so that the squeezing block 205g moves to a position where it can contact the top of the limiting column 205d. When the wrist strap body 101 is relaxed for a short time, the rotating sleeve 204c will drive the limiting column 205d to move below the squeezing block 205g. At this time, the squeezing block 205g can squeeze the arc surface of the end of the limiting column 205d, thereby pushing the limiting column 205d to move downward and separating the limiting column 205d from the limiting hole, thereby releasing the restriction on the insertion rod 205b.

[0052] A connecting rod is fixed at one end of the insertion rod 205b, and one end of the connecting rod passes through the outside of the fixed sleeve 205a, above the fixed frame 201a, and a through slot is opened at the height of the insertion rod 205b, which is not shown in the figure. The user inserts his finger into the fixed frame 201a through the through slot and pulls the connecting rod to move the insertion rod 205b, so that the insertion rod 205b can be separated from the socket 201b-2.

[0053] Specifically, a rotating disc 201c is provided above the rotating column 201b, a fixing rod 201d is fixed to the bottom of the rotating disc 201c, and the bottom end of the fixing rod 201d is inserted into the rotating column 201b and fixed with a fourth spring 201e.

[0054] The fixing rod 201d is rectangular, and rotating the turntable 201c can drive the rotating column 201b to rotate through the fixing rod 201d. The fourth spring 201e is used to apply an upward thrust to the fixing rod 201d so that it can return to its original position after moving downward.

[0055] Specifically, an extrusion rod 202d is inserted into the fixing frame 201a, a force-bearing groove 202b-1 is formed on the locking block 202b, and the bottom end of the extrusion rod 202d is matched with the force-bearing groove 202b-1.

[0056] The inner wall of the force groove 202b-1 is inclined. When the force on the wrist strap body 101 needs to be relaxed, the turntable 201c is pressed downward, so that the turntable 201c drives the squeezing rod 202d to move downward, and the squeezing rod 202d squeezes the inclined surface of the inner wall of the force groove 202b-1, thereby pushing the locking block 202b to move, and then the locking block 202b can release the restriction on the rotating column 201b, so that the force on the wrist strap body 101 can be relaxed.

[0057] During use, in an emergency, when the wrist band body 101 is needed to stop bleeding, the wrist band body 101 is worn at the designated position, and the rotating column 201b is rotated to tighten the wrist band body 101, so as to stop bleeding at the bleeding site. At the same time, the handle 204g is pulled to drive the pull rope 204f to move, so that the pull rope 204f drives the winding wheel 204e and the rotating sleeve 204c to rotate, so that the rotating sleeve 204c can tighten the coil spring 204b.

[0058] When the coil spring 204b rotates in the direction of relaxation, it will drive the rotating sleeve 204c to rotate. At this time, the direction of rotation of the rotating sleeve 204c is consistent with the direction of tightening the wrist band body 101. At the same time, the rotating sleeve 204c will drive the gear 203b to rotate through the tooth block 204d. After the coil spring 204b rotates in the direction of relaxation for a certain period of time, the wrist band body 101 will stop the bleeding at the patient's bleeding site for sufficient time. At this time, the rotating sleeve 204c will drive the gear 203b to rotate one circle through the tooth block 204d.

[0059] The gear 203b drives the push rod 203c to push the force-bearing rod 203a to move, and the force-bearing rod 203a drives the locking block 202b to separate from the locking hole 201b-1, thereby releasing the restriction on the rotating column 201b. At this time, the wrist strap body 101 can relax the locking force on the patient, thereby temporarily restoring blood circulation to the distal end of the limb and avoiding serious damage to the limb tissue caused by prolonged ischemia, such as muscle necrosis and nerve damage.

[0060] When the locking block 202b is separated from the locking hole 201b-1, the locking block 202b will drive the squeezing block 205g to move through the connecting column 205f, so that the squeezing block 205g moves to a position where it can contact the top of the limiting column 205d. When the wrist strap body 101 is relaxed for a short time, the rotating sleeve 204c will drive the limiting column 205d to move below the squeezing block 205g. At this time, the squeezing block 205g can squeeze the arc surface of the end of the limiting column 205d, thereby pushing the limiting column 205d to move downward and separating the limiting column 205d from the limiting hole, thereby releasing the restriction on the insertion rod 205b and passing The second spring 205c pushes the insertion rod 205b to move, so that the insertion rod 205b is engaged with the socket 201b-2. Through the cooperation of the two, the rotating sleeve 204c can be connected to the rotating column 201b, so that when the rotating sleeve 204c rotates, it can drive the rotating column 201b to rotate, so that the wrist band body 101 can be automatically tightened again through the rotating column 201b, thereby avoiding the situation where the wrist band body 101 is relaxed for too long, which will cause the bleeding area to bleed severely again, and when the wrist band body 101 is tightened again, the tightness of the wrist band body 101 can be adjusted by rotating the rotating column 201b.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
