Description

Technical Field

[0001] The invention relates to the technical field related to hemostats, in particular to an arterial compression hemostatant for field marches. Background Art

[0002] Troops often need to stay outdoors during training and fighting. However, during field marches, the outdoor environment is generally harsh, so accidental injuries are inevitable. Therefore, when an accident occurs, it is necessary to take timely response measures to ensure the safety of the marching soldiers.

[0003] During field marches, compression hemostasis is an essential survival and self-protection skill for everyone. Currently, most people use manual finger pressure and bandage, which is an empirical method of hemostasis. Too little pressure can easily cause bleeding; too much pressure can easily cause numbness and trembling of fingers, or even ischemia. Therefore, during field marches, soldiers will also carry special compression hemostat.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0033] See also Figure 1-9 In an embodiment of the present invention, a field march arterial compression hemostat comprises an upper box body 1 and a lower box body 2 fixed by the upper box body 1, and further comprises:

[0034] The pressing member 4 is slidably disposed on the bottom wall of the lower box body 2, and is connected to two sets of elastic support mechanisms installed in the chamber formed by the upper box body 1 and the lower box body 2. A threaded driving mechanism that cooperates with the elastic support mechanism is also installed in the chamber. When the threaded driving mechanism cooperates with the elastic support mechanism, the pressing member 4 slides toward the outside or inside of the chamber, so that the pressing member 4 performs a compression hemostasis action on the patient's artery or releases the compression state of the patient's artery.

[0035] Two groups of air outlets are provided at the bottom of the lower box body 2, and two covers 26 are fixed on the inner wall of the lower box body 2 for covering the two groups of air outlets respectively. Each of the two covers 26 is connected to a group of extraction and release mechanisms. The extraction and release mechanisms extract air during the process in which the pressing member 4 performs compression and hemostasis on the patient's artery, and pump gas into the covers 26 after the pressing member 4 releases the compression state on the patient's artery, so that the gas is blown toward the compressed part of the patient through the air outlet.

[0036] It should be noted that a strap 3 is provided on one side of the lower box body 2, and a connecting ring is provided on the other side, so that the hemostat is easy to wear in actual use. Secondly, a Velcro is provided on the strap 3 for easy fixation. Of course, snaps or other connection methods can also be used. This application does not make specific restrictions on this, and can be selected according to actual needs.

[0037] Secondly, two supporting parts 32 are fixedly provided on the bottom wall of the lower box body 2. Therefore, when the hemostat is worn, the presence of the supporting parts 32 will reserve a certain gap between the lower box body 2 and the patient's skin, reducing the contact with non-essential compression parts of the patient, thereby improving the comfort of wearing and avoiding the risk of pressure sores.

[0038] Please refer again Figure 5 The elastic support mechanism includes two cross bars 12 fixedly mounted on the inner wall of the lower box body 2, a sliding plate 13 slidably mounted on the two cross bars 12, and two first cylindrical springs 5 ​​respectively sleeved on the outer peripheries of the two cross bars 12;

[0039] Among them, one end of the first cylindrical spring 5 is connected to the inner wall of the lower box body 2, and the other end is connected to the sliding plate 13, and a connecting rod 14 is rotatably installed on both sides of the sliding plate 13, and the end of the connecting rod 14 away from the sliding plate 13 is rotatably connected to the pressing member 4.

[0040] Please refer again Figure 3 and Figure 6 The thread drive mechanism includes a bidirectional screw rod 7 rotatably mounted in the upper box body 1, a fixed column 8 fixedly mounted in the upper box body 1, and two transverse plates 9 symmetrically arranged on the bidirectional screw rod 7 and threadedly connected to the bidirectional screw rod 7;

[0041] The fixing column 8 passes through the two transverse plates 9 and is slidably connected to the two transverse plates 9 , and a rolling fitting is provided between the two transverse plates 9 and the pressing member 4 .

[0042] In detail, the bidirectional screw rod 7 is provided with two sections of threads with opposite rotation directions, and the transverse plate 9 is provided with two through holes for the bidirectional screw rod 7 and the fixed column 8 to pass through respectively, and the inner wall of the through hole through which the bidirectional screw rod 7 passes is provided with a thread that engages with the bidirectional screw rod 7.

[0043] The rolling fitting includes two inclined plates 11 symmetrically fixedly arranged on the upper part of the pressing member 4 and two round rollers 10 rotatably mounted on the two transverse plates 9 , respectively, and the round rollers 10 are in contact with the inclined plates 11 .

[0044] It should also be noted that a knob 6 is provided on one side of the upper box body 1, and the knob 6 is fixed to one end of the bidirectional screw rod 7, so that in actual use, the patient can rotate the bidirectional screw rod 7 in a forward or reverse direction through the knob 6;

[0045] When the bidirectional screw 7 rotates forward, the fixed column 8 guides the two transverse plates 9, so that the two transverse plates 9 are threadedly matched with the bidirectional screw 7 at the same time and move away from each other. Correspondingly, the round roller 10 moves with the transverse plate 9 and rolls with the inclined plate 11, so that the inclined plate 11 gives way and moves downward, so that the pressing member 4 gradually slides toward the outside of the chamber formed by the upper box body 1 and the lower box body 2 to perform compression and hemostasis on the patient's artery. At the same time, in the process again, the pressing member 4 pushes the sliding plate 13 on the two cross bars 12 to slide toward the inner wall of the lower box body 2 through the connecting rod 14, and the first column spring 5 is gradually compressed;

[0046] On the contrary, when the bidirectional screw 7 rotates in the opposite direction, similarly, the two transverse plates 9 will simultaneously perform threaded cooperation with the bidirectional screw 7 and move closer to each other, so that the first cylindrical spring 5 gradually rebounds, and the sliding plate 13 gradually slides toward the pressing piece 4 on the two cross bars 12, and drives the pressing piece 4 to gradually slide toward the inside of the chamber formed by the upper box body 1 and the lower box body 2 through the connecting rod 14, thereby relieving the compression state of the patient's artery.

[0047] In summary, the hemostat is easy to use and carry. Soldiers can wear it to stop bleeding during field marches, which brings convenience to the activities of soldiers and is suitable for popularization and use.

[0048] Please refer again Figure 6-9 A mounting plate 15 is fixed on each side of one of the transverse plates 9, and two sets of the extraction and release mechanisms are respectively installed on the two assembly plates 15. The extraction and release mechanisms include an elastic follower assembly installed on the assembly plate 15 and a unidirectional conductive structure connecting the elastic follower assembly and the cover body 26.

[0049] The one-way conducting structure comprises a box body 16 fixedly mounted on the assembly plate 15, one end of the box body 16 is a conducting structure, and a piston plate 22 is provided inside the box body 16 in a sealing and sliding manner, and the piston plate 22 is fixedly connected to a long strip plate 21, and the long strip plate 21 is sealingly and slidably connected to the box body 16, and the end thereof away from the piston plate 22 is connected to the elastic follower assembly;

[0050] The box body 16 is also provided with a first one-way valve 23 and a second one-way valve 24 , and the second one-way valve 24 is connected to the cover body 26 via a hose 25 .

[0051] When the two transverse plates 9 move away from each other, that is, when the pressing member 4 performs compression and hemostasis on the patient's artery, the elastic follower component will store elastic potential energy, and the long plate 21 pushes the piston plate 22 to slide inside the box body 16 toward the conductive side of the box body 16. During this process, the first one-way valve 23 is conductive, while the second one-way valve 24 is not conductive, so that gas will be sucked into the box body 16 through the first one-way valve 23. Subsequently, after the two transverse plates 9 are reset close to each other, that is, the pressing member 4 releases the compression state on the patient's artery. After that, the elastic follower component will release the elastic potential energy, and the long plate 21 will pull the piston plate 22 to slide inside the box body 16 toward the side away from the box body 16. During this process, the first one-way valve 23 is not conductive, while the second one-way valve 24 is conductive. Therefore, the gas in the box body 16 can be discharged into the cover body 26 through the second one-way valve 24 and the hose 25, and then blown to the compressed part of the patient through the air outlet at the bottom of the lower box body 2, thereby having the effect of drying the compressed part of the patient and making the patient feel more comfortable.

[0052] The elastic follower assembly includes a guide rod 18 fixedly mounted on the assembly plate 15 through a protrusion block 17 and a slider 19 slidably arranged on the guide rod 18 and the assembly plate 15, and the slider 19 is fixed to an end of the long plate 21 away from the piston plate 22;

[0053] Among them, the outer periphery of the guide rod 18 is also sleeved with a second cylindrical spring 20, and the two ends of the second cylindrical spring 20 are respectively connected to the protruding block 17 and the slider 19. A column 27 is also fixed on the slider 19, and a sliding groove for the column 27 to extend into is opened on the top wall of the upper box body 1.

[0054] Please refer again Figure 8 The slide groove includes an inclined section 28, a first long straight section 29 and a second long straight section 30, and a movable part 31 is rotatably installed at the connection between the inclined section 28 and the first long straight section 29, and a torsion spring is provided on the rotating shaft of the movable part 31.

[0055] When the two transverse plates 9 move away from each other, the column 27 will slide in the inclined section 28, and the movable member 31 will rotate in the latter part of the movement (when the movable member 31 rotates, the torsion spring will be deformed, and after the column 27 enters the first long straight section 29, the torsion spring will be reset, so that the movable member 31 will rotate and reset again), and then the column 27 will enter the first long straight section 29. During the movement of the column 27 in the inclined section 28, the slider 19 will gradually slide toward the box body 16 on the assembly plate 15 and the guide rod 18, the second column spring 20 will be stretched, and the long strip plate 21 will push the piston plate 22 to slide inside the box body 16 toward the conductive side of the box body 16;

[0056] When the two transverse plates 9 move toward each other, the column 27 slides in the first long straight section 29 into the second long straight section 30. After the two transverse plates 9 are reset, the column 27 enters the second long straight section 30. At this time, the second column spring 20 elastically recovers, so that the slider 19 slides and resets on the assembly plate 15 and the guide rod 18 in the direction away from the box body 16, and pulls the piston plate 22 through the long strip plate 21 to slide inside the box body 16 toward the side that is connected to the box body 16, so that the gas in the box body 16 is discharged into the cover body 26 through the second one-way valve 24 and the hose 25, and then blows toward the compressed part of the patient through the air outlet at the bottom of the lower box body 2.

[0057] When the field march arterial compression hemostat is implemented, the patient can wear the hemostat on the part to be hemostatically controlled by means of the bandage 3. When the bidirectional screw 7 rotates forward, the fixed column 8 guides the two transverse plates 9, so that the two transverse plates 9 are threadedly matched with the bidirectional screw 7 at the same time and move away from each other. Accordingly, the round roller 10 moves along with the transverse plate 9 and rolls with the inclined plate 11, so that the inclined plate 11 gives way and moves downward. Thus, the pressing member 4 gradually slides toward the outside of the chamber formed by the upper box body 1 and the lower box body 2 to perform compression and hemostasis on the patient's artery. At the same time, in the process again, the pressing member 4 pushes the sliding plate 13 on the two transverse bars 12 to slide toward the inner wall of the lower box body 2 through the connecting rod 14, and the first column spring 5 is gradually compressed.

[0058] On the contrary, when the bidirectional screw 7 rotates in the opposite direction, similarly, the two transverse plates 9 will simultaneously engage with the bidirectional screw 7 in threaded engagement and move toward each other, so that the first cylindrical spring 5 gradually rebounds, and the sliding plate 13 gradually slides toward the pressing member 4 on the two cross bars 12, and drives the pressing member 4 to gradually slide toward the inside of the chamber formed by the upper box body 1 and the lower box body 2 through the connecting rod 14, thereby releasing the compression state of the patient's artery;

[0059] When the two transverse plates 9 move away from each other, that is, during the process of the pressing member 4 performing compression and hemostasis on the patient's artery, the column 27 will slide in the inclined section 28, and the movable member 31 will rotate in the latter part of the movement (when the movable member 31 rotates, the torsion spring will be deformed, and after the column 27 enters the first long straight section 29, the torsion spring will be reset, so that the movable member 31 will rotate and reset again). Then, the column 27 enters the first long straight section 29. During the movement of the column 27 in the inclined section 28, the slider 19 will gradually slide toward the box body 16 on the assembly plate 15 and the guide rod 18, the second column spring 20 will be stretched, and the long strip plate 21 will push the piston plate 22 to slide inside the box body 16 toward the conductive side of the box body 16. The first one-way valve 23 is conductive, while the second one-way valve 24 is not conductive. Therefore, gas will be sucked into the box body 16 through the first one-way valve 23;

[0060] When the two transverse plates 9 move towards each other, the column 27 slides in the first long straight section 29 to the second long straight section 30. After the two transverse plates 9 are reset, the column 27 enters the second long straight section 30. At this time, the second column spring 20 elastically recovers, so that the slider 19 slides and resets on the assembly plate 15 and the guide rod 18 in the direction away from the box body 16, and pulls the piston plate 22 through the long strip plate 21 to slide inside the box body 16 toward the side away from the box body 16. The first one-way valve 23 is not conductive, and the second one-way valve 24 is conductive. Therefore, the gas in the box body 16 can be discharged into the cover body 26 through the second one-way valve 24 and the hose 25, and then blown to the compressed part of the patient through the air outlet at the bottom of the lower box body 2, thereby having the effect of drying the compressed part of the patient, so that the patient has a greater sense of comfort.

[0061] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
