Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and more particularly to a hemostatic compression device for medical care. Background Art

[0002] It is relatively easy for most patients to stop bleeding by pressing. However, for patients with severe illness or who cannot take care of themselves, they cannot complete the above pressing process by themselves. This requires medical staff to press the puncture point for a long time. During the pressing process on the patient, subcutaneous congestion or epidermal bleeding may occur due to improper pressing force or short pressing time. This undoubtedly increases the burden on medical staff and causes certain harm to patients.

[0003] The existing knob-type compressor consists of a plastic plate, a compression head and a bandage. When installed, the compression head is aligned with the puncture point for compression, and the compressor is fixed to the patient's body with a cotton bandage to stop bleeding. However, although the above device can stop bleeding for the patient, it cannot uniformly and effectively compress the skin around the puncture site according to the patient's actual situation, which has a certain impact on the patient's recovery period.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the present invention, the position of the strap is locked by Velcro 1 and Velcro 2. When the strap is wrapped around the patient's wrist, the cover pressure plate body will be placed on the patient's injection area. Then the pressure block on the pressure rod is adjusted by the adjustment mechanism so that the compression block in the pressure block applies pressure to the puncture point, thereby achieving positioning and pressing of the puncture point.

[0017] 2. In the present invention, the sleeve is driven to rotate by the worm gear mechanism, so that the rotating ring on the outer wall of the sleeve rotates, and the sliding channel in the rotating ring moves with a sliding rod. When the two groups of sliding rods move to the nearest end or the farthest end in the sliding channel, the two groups of pressure plates move towards or away from each other, and the pressure in the airbag increases or decreases, thereby adjusting the extrusion force of the airbag. This not only expands the extrusion range, but also ensures the uniformity of force on the bleeding site.

[0018] 3. In the present invention, the sleeve drives the deflection plate on the sleeve to rotate. Since the groove and the interference groove in the deflection plate are located in different planes, the movable rod is subjected to different pressures. When the movable rod moves downward, the spherical block 1 and the spherical block 2 on the connecting rod are deflected in the spherical sleeve 1 and the spherical sleeve 2. At this time, the pressure is transmitted to the compression plate through the spherical sleeve 2. Combined with the hinge between adjacent compression plates and the spring force of the compression spring, each compression plate generates pressure on the patient's skin. This not only ensures the uniformity of pressure, but also adapts to the patient's skin as much as possible, and has a better pressing effect.

[0019] 4. In the present invention, the existing single compression device is replaced by a fine-tuning mechanism and an adapting mechanism to form a stable pressure source at the patient's puncture site. The extrusion range is expanded by the inflated airbag and the hinged compression plate, and the uniformity of the skin around the puncture site is ensured, which effectively reduces the patient's discomfort and greatly reduces the labor intensity of medical staff.

DETAILED DESCRIPTION

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and 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.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0034] Embodiment 1 of the present invention further describes a hemostatic compression device for medical care, including a cover plate body 100, with ears 101 formed integrally on both sides of the cover plate body 100, with openings 102 in the ears 101, with straps 103 in the openings 102 on both sides, the straps 103 are respectively connected to the ears 101 on both sides to form a ring, and the corresponding positions on both sides of the outer wall of the strap 103 are fixedly connected with Velcro 104 and Velcro 2 105, the Velcro 104 and Velcro 2 105 cooperate, and the upper end surface of the cover plate body 100 A through hole 106 is provided, and a base 107 is fixedly connected to the upper end surface of the cover pressure plate body 100, and an adjustment mechanism 400 is provided in the base 107. The adjustment mechanism 400 is provided with a mounting plate 108, including a pressure rod 109 fixedly connected to the mounting plate 108, and the pressure rod 109 is arranged on the inner side of the cover pressure plate body 100 facing the strap 103, and a pressure block 110 is fixedly connected to one end of the pressure rod 109, and a compression groove 111 is provided in the compression block 110, and a compression block 112 is fixedly connected to the compression groove 111, and an air bag 113 is detachably connected to the outer side of the compression block 112;

[0035] The present invention provides a strap 103 that can be wrapped around the wrist, and the position of the strap 103 is locked by Velcro 104 and Velcro 2 105. The connection of the strap 103 is wrapped with a cover plate body 100. When the strap 103 is wrapped around the patient's wrist, the cover plate body 100 will be placed on the patient's injection area. Then, the pressure block 110 on the pressure rod 109 is adjusted by the adjustment mechanism 400, so that the compression block 112 in the pressure block 110 applies pressure to the puncture point, thereby achieving positioning and pressing of the puncture point.

[0036] At the same time, the present invention also arranges an airbag 113 outside the compression block 112, and the airbag 113 is a ring structure, which contacts and compresses the skin near the puncture point, ensuring the compression range while avoiding excessive compression force to cause harm to the patient. The present invention further refines the air intake method of the airbag 113, so that when the device needs to expand the pressing force or the pressing range, the air intake amount of the airbag 113 is changed, thereby achieving the effect of adjusting the compression force;

[0037] In this way, the present invention can select different pressing methods according to actual conditions. However, in actual use, since the patient's skin is not necessarily flat, when the compression block 112 or the airbag 113 is selected for pressing, the skin around the patient may not be taken into account, resulting in a poor pressing effect and affecting the patient's recovery. The internal structure of the pressing block 110 of the device is further limited. By arranging an adaptation mechanism 300 in the pressing block 110, the pressing can be as uniform as possible on the patient's skin during pressing, and a better pressing effect is achieved.

[0038] The fine adjustment mechanism 200 is also provided in the mounting plate 108, and the fine adjustment mechanism 200 includes a driving member 201 provided in the mounting plate 108, a support member 202 is provided on the outer wall of the pressure rod 109, a rotating member 203 is provided in the support member 202, a compression member 204 cooperating with the rotating member 203 is provided in the support member 202, and one end of the compression member 204 is correspondingly provided on the airbag 113, Figures 1 to 10 It can be seen that the present invention arranges a driving member 201 on the bottom plate of the mounting plate 108, and drives the rotating member 203 to operate through the driving member 201. When the rotating member 203 operates synchronously, the rotating member 203 cooperates with the compression member 204 to change the pressure in the airbag 113, thereby achieving the effect of adjusting the pressure of the airbag 113.

[0039] The adapting mechanism 300 is also included. The adapting mechanism 300 is arranged on a deflecting member 301 in the pressing block 110. A movable member 302 is also arranged in the pressing block 110. The deflecting member 301 and the movable member 302 cooperate with each other. A spherical member 303 is arranged at one end of the movable member 302. A pressing member 304 is arranged on the spherical member 303. The spherical member 303 and the pressing member 304 cooperate with each other to press the bleeding area. Figures 1 to 10 It can be known that a deflection member 301 is arranged in the pressing block 110. When the rotating member 203 is in operation, the deflection member 301 is driven to move synchronously. The deflection member 301 enables the compression member 304 on the spherical member 303 to be pressed on the patient's skin as evenly as possible. The adjustment mechanism 400 includes a fixing member 401 arranged in the base 107. A moving ring 402 is arranged in the fixing member 401. A limiting member 403 is arranged on one side of the moving ring 402. The moving ring and the limiting member 403 cooperate to adjust the position of the mounting plate 108. The limiting member 403 is used to limit the rotation direction of the moving ring 402, so that the moving ring 402 can only move in the vertical direction, thereby ensuring the compression force of the compression member 304 on the patient.

[0040] Working principle: The device can be used in three situations. First, when in use, the position of the strap 103 can be locked by Velcro 104 and Velcro 2 105. When the strap 103 is wrapped around the patient's wrist, the cover plate body 100 will be placed on the patient's injection area. Then, the pressure block 110 on the pressure rod 109 is adjusted by the adjustment mechanism 400, so that the compression block 112 in the pressure block 110 applies pressure to the puncture point, thereby achieving the positioning and pressing of the puncture point. Second, when the air needs to be adjusted, When the compression force of the airbag 113 is increased, it is only necessary for the driving member 201 to drive the rotating member 203 to operate. When the rotating member 203 operates synchronously, the pressure in the airbag 113 changes through the cooperation of the rotating member 203 and the compression member 204, thereby achieving the effect of adjusting the pressure of the airbag 113. Thirdly, by arranging an adaptation mechanism 300 in the pressing block 110, the compression member 304 on the spherical member 303 can be pressed on the patient's skin as evenly as possible through the deflection member 301, thereby having a better pressing effect.

[0041] Embodiment 2

[0042] The following technical features are added on the basis of the first embodiment: the driving member 201 includes a fixed cylinder 201a fixedly connected to the bottom end of the mounting plate 108, a driving chamber 201b is formed between the fixed cylinder 201a and the mounting plate 108, a sleeve 201c is rotated in the fixed cylinder 201a, the sleeve 201c surrounds the pressure rod 109, a worm wheel 201d is fixedly connected to the outer wall of the sleeve 201c, a worm 201e is meshedly connected to one side of the worm wheel 201d, and the worm 201e is rotatably connected to the In the fixed cylinder 201a, the worm 201e penetrates through one end of the fixed cylinder 201a and is fixedly connected to a turning handle 201f. The support member 202 includes a support block 202a fixedly connected to the bottom end of the fixed cylinder 201a. A cavity 202b is provided in the support block 202a. The fixed cylinder 201a is correspondingly connected to the cavity 202b. The diameter of the support block 202a is smaller than the diameter of the through hole 106. The support block 202a is provided between the pressing block 110 and the fixed cylinder 201a.

[0043] Depend on Figures 1 to 10 It can be seen that the fixed cylinder 201a is provided with a circular structure of a driving chamber 201b, and a sleeve 201c is connected by rotating inside the fixed cylinder 201a. The sleeve 201c is an annular structure, surrounding the pressure rod 109. There is no connection between the sleeve 201c and the pressure rod 109. A worm wheel 201d is fixedly connected to the outer wall of the sleeve 201c, and a worm 201e is meshedly connected to one side of the worm wheel 201d. The worm 201e is driven to rotate by turning the handle 201f, so that the sleeve 201c in the worm wheel 201d is driven to rotate. A circular support block 202a is fixed to the bottom end of the fixed cylinder 201a, and it can be concluded that the corresponding support block 202a of the pressure rod 109 passes through;

[0044] The rotating member 203 includes a rotating ring 203a fixedly connected to the outer wall of the sleeve 201c, the rotating ring 203a is composed of an inner ring 203b and an outer ring 203c, a sliding channel 203d is formed between the inner ring 203b and the outer ring 203c, and a mounting portion 203e is formed in the middle of the inner ring 203b and the outer ring 203c. The mounting portion 203e is fixedly connected to the outer wall of the sleeve 201c, and the outer ring 203c is straight. The diameter of the inner ring 203b is larger than that of the inner ring 203b, the sliding channel 203d includes two groups of the closest end 203f, the most distal end 203g and the reduced diameter end 203h, the reduced diameter end 203h is correspondingly arranged between the closest end 203f and the most distal end 203g, the two groups of the closest end 203f, the most distal end 203g and the reduced diameter end 203h are symmetrical, and two groups of sliding rods 203i are slidably connected in the sliding channel 203d, and the two groups of sliding rods 203i are symmetrical;

[0045] Depend on Figure 6 and Figure 7 It can be seen that a rotating ring 203a is fixedly connected to the outer wall of the sleeve 201c, and the rotating ring 203a is composed of an inner ring 203b and an outer ring 203c. The inner ring 203b and the outer ring 203c have the same structure, which is a figure eight structure. The diameter of the outer ring 203c is larger than the diameter of the inner ring 203b. A sliding channel 203d is formed between the inner ring 203b and the outer ring 203c. Two sets of sliding rods 203 symmetrically slide in the sliding channel 203d. i, since the sliding channel 203d is divided into the closest end 203f, the farthest end 203g and the diameter-changing end 203h, when the rotating ring 203a rotates, the position of the sliding rod 203i in the sliding channel 203d changes. When the two sets of sliding rods 203i move to the closest end 203f correspondingly, the distance between the two sets of sliding rods 203i is the closest. When the two sets of sliding rods 203i move to the farthest end 203g correspondingly, the distance between the two sets of sliding rods 203i is the farthest.

[0046] The compression member 204 includes a compression cylinder 204a fixedly connected to both ends of the cavity 202b, a movable cavity 204b is provided in the compression cylinder 204a, a piston plate 204c is slidably connected in the movable cavity 204b, a pressing plate 204d is fixedly connected to one end of the piston plate 204c, the pressing plate 204d correspondingly penetrates the compression cylinder 204a, the sliding rod 203i is correspondingly fixedly connected to the pressing plate 204d, an air outlet hole 204e is provided on one side of the movable cavity 204b, an air outlet pipe 204f is seamlessly connected in the air outlet hole 204e, and one end of the air outlet pipe 204f penetrates the compression block 110 and is arranged on the airbag 113;

[0047] Depend on Figures 4 to 6It can be seen that the present invention arranges two groups of compression cylinders 204a at both ends of the cavity 202b, and the two groups of compression cylinders 204a are correspondingly connected with piston plates 204c in sliding connection. The movement of the piston plate 204c inside the active cavity 204b causes the volume of gas in the active cavity 204b to change, so that the gas is transmitted to the airbag 113 along the gas outlet pipe 204f. In summary, the present device can adjust the compression force by changing the gas volume;

[0048] Working principle: It can be seen from Example 1 that when adjusting the pressure of the airbag 113, it is only necessary to turn the handle 201f, and the handle 201f drives the worm 201e to rotate. The worm 201e is meshed and connected to one side of the worm wheel 201d. When the worm wheel 201d rotates, it drives the sleeve 201c to rotate. When the sleeve 201c rotates, it drives the rotating ring 203a on the outer wall of the sleeve 201c to rotate. The sliding channel 203d in the rotating ring 203a moves the slide rod 203i, and the upper end of the slide rod 203i is fixedly connected to the pressure plate 204d. The pressure plate 204d can only be compressed in the compression cylinder 204a. When the two sets of slide bars 203i move to the nearest end 203f in the sliding channel 203d, the two sets of pressure plates 204d move towards each other, and the pressure in the airbag 113 decreases. When the two sets of slide bars 203i move to the farthest end 203g in the sliding channel 203d, the two sets of pressure plates 204d move back to back. At this time, the movement of the piston plate 204c inside the active chamber 204b causes the volume of the gas in the active chamber 204b to change, so that the gas is transmitted to the airbag 113 along the outlet pipe 204f, thereby increasing the pressure of the airbag 113 on the skin surface.

[0051] Depend on Figures 2 to 10 It can be seen that a circular deflection cavity 301a is provided in the pressing block 110, and a sleeve 201c is provided at the position of the deflection cavity 301a and fixedly connected with a deflection plate 301b. When the sleeve 201c rotates, the deflection plate 301b is driven to rotate synchronously. A groove 301c and a resistance groove 301d are provided at the bottom of the deflection plate 301b. The groove 301c and the resistance groove 301d are adjacent to each other. Since the groove 301c and the resistance groove 301d are located in different planes, when the deflection plate 301b rotates, the position where the conical block 302c on the movable rod 302a contacts the deflection plate 301b is different. Figure 5 It can be seen that the cavity 202b is connected with a movable rod 302a via a compression spring 302b. When the movable rod 302a contacts the abutment groove 301d, the movable rod 302a is driven to move downward under the pressure of the abutment groove 301d. When the movable rod 302a contacts the groove 301c, the movable rod 302a is driven to move upward under the restoring force of the compression spring 302b.

[0052] The spherical member 303 comprises a spherical sleeve 1 303a fixedly connected to the outer wall of the movable rod 302a, a spherical block 1 303b is movably connected in the spherical sleeve 1 303a, a connecting rod 303c is fixedly connected in the spherical block 1 303b, a spherical block 2 303d is fixedly connected at one end of the connecting rod 303c, the pressing member 304 comprises a plurality of groups of pressing plates 304a, a hinge shaft 304b is arranged between two adjacent groups of pressing plates 304a, two ends of the pressing plates 304a are respectively a pressing surface 304c and a supporting surface 304d, a spherical sleeve 2 304e is fixedly connected to the upper end surface of the supporting surface 304d, the spherical block 2 303d is correspondingly movably connected in the spherical sleeve 2 304e, the pressing surface 304c is correspondingly pressed against the skin surface, and a gap area is formed between the plurality of groups of pressing plates 304a, and the hinge shaft 304b is arranged in the gap area;

[0053] Depend on Figures 5 to 9It can be seen that the present invention further defines the structure of the movable rod 302a, wherein a spherical connection mechanism is fixedly connected to the outer wall of the movable rod 302a, and a spherical block 1 303b and a spherical block 2 303d are connected to the two ends of the connecting rod 303c. The spherical block 1 303b moves in the spherical sleeve 1 303a, and the spherical block 2 303d moves in the spherical sleeve 2 304e. Since the spherical sleeve 2 304e is fixed to the outer wall of the compression plate 304a, and the adjacent compression plates 304a are connected by the hinge shaft 304e. 4b connection, when the movable rod 302a moves downward, the spherical block 1 303b and the spherical block 2 303d on the connecting rod 303c are deflected in the spherical sleeve 1 303a and the spherical sleeve 2 304e. At this time, the pressure is transmitted to the compression plate 304a through the spherical sleeve 2 304e. Combined with the hinge between adjacent compression plates 304a and the spring force of the compression spring 302b, each compression plate 304a generates pressure on the patient's skin, thereby ensuring the uniformity of the patient's force.

[0054] Working principle: As can be seen from Example 2, when the sleeve 201c rotates, the deflection plate 301b on the sleeve 201c is synchronously driven to rotate. Since the groove 301c and the abutment groove 301d in the deflection plate 301b are located in different planes, the pressure on the movable rod 302a is different. When the movable rod 302a contacts the abutment groove 301d, the movable rod 302a is driven to move downward under the pressure of the abutment groove 301d. When the movable rod 302a contacts the groove 301c, the movable rod 302a is driven upward under the restoring force of the compression spring 302b. When the movable rod 302a moves downward, the spherical block 1 303b and the spherical block 2 303d on the connecting rod 303c are deflected in the spherical sleeve 1 303a and the spherical sleeve 2 304e. At this time, the pressure is transmitted to the compression plate 304a through the spherical sleeve 2 304e. Combined with the hinge between adjacent compression plates 304a and the spring force of the compression spring 302b, each compression plate 304a generates pressure on the patient's skin, which not only increases the pressure range, but also ensures the uniformity of the pressure and adapts to the patient's skin as much as possible, thereby having a better pressing effect.
