Description

Technical Field

[0001] The present invention relates to the technical field of design and manufacturing of VTE prevention equipment, in particular to a fixing device of VTE prevention control equipment. Background Art

[0002] VTE prevention and control devices refer to a class of medical devices used to prevent and control venous thromboembolism, a common complication, especially in hospitalized patients, surgical patients and those who are bedridden for a long time, which may lead to serious health problems such as pulmonary embolism.

[0003] When the antithrombotic pump is used, the antithrombotic pump is clamped next to the bed, and then the patient's foot is put into the foot cuff, and then the antithrombotic pump is started to intermittently inflate and deflate the foot cuff, thereby squeezing the patient's body muscles to accelerate the blood flow rate and prevent venous blood from stagnating and causing venous thrombosis. However, when the antithrombotic pump is not in use, it needs to be placed. However, when the antithrombotic pump is placed, it may tilt due to its own weight or be hit by external factors, causing the antithrombotic pump to fall and be damaged;

[0004] Furthermore, when an antithrombotic pump is used on a patient, the patient may experience foot pain due to long-term use of the antithrombotic pump, and the patient may move around in response to the pain. The existing antithrombotic pump is secured by a snap-on connection, but when the patient moves around, the antithrombotic pump being used may be pulled off the bed and fall and be damaged. Furthermore, the antithrombotic pump may be compressed and damaged if the patient accidentally kicks it when in pain or if the patient's family members accidentally sit on it when visiting the patient.

DETAILED DESCRIPTION

[0031] The following will be combined with the accompanying drawings in 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] When the antithrombotic pump 1 is used, the antithrombotic pump 1 is clamped beside the bed, and then the patient's foot is put into the foot cuff 2, and then the antithrombotic pump 1 is started to intermittently inflate and deflate the foot cuff 2, thereby squeezing the patient's body muscles to accelerate the blood flow rate and prevent venous blood from stagnating and causing venous thrombosis. However, when the antithrombotic pump 1 is not in use, the antithrombotic pump 1 needs to be placed. However, when the antithrombotic pump 1 is placed, it may tilt due to its own weight or be hit by external factors, causing the antithrombotic pump 1 to fall and be damaged;

[0033] Furthermore, when the antithrombotic pump 1 is used on a patient, the patient may suffer from foot pain due to long-term use of the antithrombotic pump 1, and the patient may move around in response to the pain. The antithrombotic pump 1 is secured by a snap connection, but when the patient moves around, the antithrombotic pump 1 being used may be pulled off the bed and fall and be damaged. Furthermore, if the patient accidentally kicks the antithrombotic pump 1 when in pain or the patient's family members accidentally sit on the antithrombotic pump 1, the antithrombotic pump 1 may be compressed and damaged. For example, the present invention is implemented as follows. Figures 1 to 9A fixing device for a VTE prevention and control device comprises an antithrombotic pump 1, foot cuffs 2 are detachably mounted on both sides of the antithrombotic pump 1, a clamping support structure 300 is disposed at the bottom of the antithrombotic pump 1, a swing structure 400 is disposed at the top of the clamping support structure 300, and a limited position structure 500 is disposed between the clamping support structure 300 and the swing structure 400;

[0034] When in use, the clamping support structure 300 rotates counterclockwise to firmly clamp the bed, driving the swing structure 400 to descend and form a ">" and "<" to support the thrombus pump 1, and driving the limiting structure 500 to be in a clamping state;

[0035] When not in use, the anti-thrombotic pump 1 is firmly placed by rotating the clamping support structure 300 clockwise into a "U" shape, while driving the swing structure 400 to lift the anti-thrombotic pump 1 away from the desktop.

[0036] The present invention takes into account that when the antithrombotic pump 1 is used on a patient, the patient may suffer from foot pain due to long-term use of the antithrombotic pump 1, and the patient may move around in response to the pain. In addition, the antithrombotic pump 1 is firmly secured by a clamping connection, but when the patient moves around, the antithrombotic pump 1 in use may be pulled and fall off the bed and be damaged. In addition, if the patient accidentally kicks the antithrombotic pump 1 when in pain or the patient's family members accidentally sit on the antithrombotic pump 1, the antithrombotic pump 1 may be compressed and damaged. Therefore, the clamping support structure 300 is rotated counterclockwise to clamp the bed firmly and drive the swing structure 300 to rotate counterclockwise to clamp the bed firmly. The structure 400 descends and forms “>” and “<” to support the anti-thrombotic pump 1, and drives the limiting structure 500 to be in a clamping state, so that the anti-thrombotic pump 1 can be clamped firmly while the center of gravity of the anti-thrombotic pump 1 is tilted downward, and the swing structure 400 can form “>” and “<” to support the anti-thrombotic pump 1, and when the top of the anti-thrombotic pump 1 is pressed by external force, the limiting structure 500 can limit the anti-thrombotic pump 1 and rebound, thereby effectively preventing the anti-thrombotic pump 1 from being firmly clamped when the patient moves around, and preventing the anti-thrombotic pump 1 from being damaged by external force, thereby improving practicality;

[0037] Furthermore, when the antithrombotic pump 1 is used, the antithrombotic pump 1 is clamped next to the bed, and then the patient's foot is put into the foot cuff 2, and then the antithrombotic pump 1 is started to intermittently inflate and deflate the foot cuff 2, thereby squeezing the patient's body muscles to accelerate the blood flow rate and prevent venous blood from stagnating and causing venous thrombosis. However, when the antithrombotic pump 1 is not in use, the antithrombotic pump 1 needs to be placed. However, when the antithrombotic pump 1 is placed, it may tilt due to its own weight or be hit by external factors, causing the antithrombotic pump 1 to fall and be damaged. Therefore, the anti-thrombotic pump 1 is stably placed by rotating the clamping support structure 300 clockwise into a "U" shape and driving the swinging structure 400 to lift the anti-thrombotic pump 1 away from the desktop, so that the clamping support structure 300 can be effectively set in a "U" shape when not in use, which makes the anti-thrombotic pump 1 more stable when placed, and the swinging structure 400 swings to lift the anti-thrombotic pump 1 away from the desktop, which not only effectively prevents the anti-thrombotic pump 1 from tilting when placed, but also keeps the anti-thrombotic pump 1 away from the desktop to prevent water stains or dust from entering;

[0038] In order to achieve a stable clamping of the anti-thrombotic pump 1, the following specific structures need to be disclosed in detail:

[0039] The clamping support structure 300 includes a first rotating shaft 302, which is rotatably connected to the inner wall of the anti-thrombotic pump 1, and a first rotating disk 301 is fixedly connected to one end of the first rotating shaft 302 away from the anti-thrombotic pump 1, and a first arc plate 303 is fixedly connected to the surface of the first rotating shaft 302;

[0040] The inner wall of the anti-thrombotic pump 1 is rotatably connected to a second rotating shaft 305, a side of the second rotating shaft 305 away from the anti-thrombotic pump 1 is fixedly connected to a second rotating disk 304, and a second arc plate 306 is fixedly connected to the surface of the second rotating shaft 305.

[0041] First, the staff holds the anti-thrombotic pump 1, and then manually rotates the first rotating disk 301 counterclockwise to drive the first rotating shaft 302. The first rotating disk 301 is for the convenience of medical staff to rotate, and the first rotating shaft 302 rotates to make the first curved plate 303 approach the bed and fit the bed. In addition, the staff also needs to manually rotate the second rotating disk 304 clockwise to drive the second rotating shaft 305 to rotate on the inner wall of the anti-thrombotic pump 1, so that the second curved plate 306 approaches the bed and fits the bed. At this time, the first curved plate 303 and the second curved plate 306 fit each other with the bed, so that the anti-thrombotic pump 1 can be stabilized while preventing the patient from moving around. The anti-thrombotic pump 1 can still be stabilized by clamping the first curved plate 303 and the second curved plate 306, thereby improving the stabilization effect of the anti-thrombotic pump 1.

[0042] In order to make the center of gravity of the anti-thrombotic pump 1 downward, the following specific structure needs to be disclosed in detail, please refer to Figures 1 to 6 The swing structure 400 includes a first swing plate 401, the first swing plate 401 is fixedly connected to the surface of the first rotating shaft 302, the first swing plate 401 is rotatably connected to the second limiting shaft 404 on the side away from the first rotating shaft 302, the second limiting shaft 404 is rotatably connected to the second swing plate 402 on the surface, the second swing plate 402 is rotatably connected to the first limiting shaft 403 on the side away from the second limiting shaft 404, and the first limiting shaft 403 is fixedly connected to the inner wall of the anti-thrombotic pump 1;

[0043] When the first rotating shaft 302 rotates, the two groups of first swinging plates 401 will be driven to swing away from each other, and the second limiting shaft 404 will be driven to swing at the same time. At that time, because the second swinging plate 402 is limited by the first limiting shaft 403 and is telescopic, when the second limiting shaft 404 swings, the second swinging plate 402 will be driven to swing around the first limiting shaft 403, and will be stretched when the second swinging plate 402 swings, thereby preventing the second swinging plate 402 from being able to contact the inner wall of the anti-thrombotic pump 1. When the first swinging plate 401 and the second swinging plate 402 swing to the maximum distance, the first swinging plate 401 and the second swinging plate 402 will be in a "<" shape and contact the inner wall of the anti-thrombotic pump 1, and finally in a Figure 7 As shown, on the contrary, when the third swing plate 405 and the fourth swing plate 408 swing to the maximum distance, the third swing plate 405 and the fourth swing plate 408 will be in a "<" shape and contact the inner wall of the anti-thrombotic pump 1, so that the anti-thrombotic pump 1 can be stabilized, and the anti-thrombotic pump 1 can be effectively prevented from tilting due to external collision or its own weight, thereby increasing the service life of the anti-thrombotic pump 1;

[0044] In order to improve the stability of the anti-thrombotic pump 1, the following specific structures need to be disclosed in detail. Please refer to Figure 6 and Figure 7 The second swing plate 402 is telescopically arranged, the length of the first limit shaft 403 is adapted to the inner wall of the anti-thrombotic pump 1, and two groups of second swing plates 402 are symmetrically arranged along the transverse center of the second limit shaft 404. The first limit shaft 403 rotatably connected inside the second swing plate 402 penetrates the two groups of second swing plates 402, and both ends of the second limit shaft 404 are rotatably connected to the two groups of first swing plates 401;

[0045] When the first swing plate 401 swings to the maximum distance, the second swing plate 402 is at the maximum telescopic swing distance, and the first swing plate 401 and the second swing plate 402 are provided with two groups, so as to prevent the first swing plate 401 and the second swing plate 402 from failing to cooperate with each other to stabilize the anti-thrombotic pump 1, and at the same time, the two groups of the first swing plate 401 and the second swing plate 402 can improve the stabilizing effect of the anti-thrombotic pump 1;

[0046] In order to stabilize the other side of the inner wall of the anti-thrombotic pump 1, the following specific structure needs to be disclosed in detail, please refer to Figure 5 The inner wall of the anti-thrombotic pump 1 is fixedly connected with a fourth limiting shaft 407, and a fourth swing plate 408 is rotatably connected with the surface of the fourth limiting shaft 407. The fourth swing plate 408 is telescopically arranged, and a side of the fourth swing plate 408 away from the fourth limiting shaft 407 is rotatably connected with the third limiting shaft 406, and both ends of the third limiting shaft 406 are rotatably connected with the third swing plate 405, and a side of the third swing plate 405 away from the third limiting shaft 406 is fixedly connected to the surface of the second rotating shaft 305;

[0047] When the second rotating shaft 305 rotates clockwise, it drives the two sets of third swing plates 405 to swing and drives the third limit shaft 406 to swing, and at the same time drives the fourth swing plate 408 to form a “>” with the third swing plate 405 and stabilize the other side of the inner wall of the anti-thrombus pump 1, thereby improving the stability of the anti-thrombus pump 1;

[0048] In order to prevent the anti-thrombotic pump 1 from being damaged by external pressure, the following specific structure needs to be disclosed in detail. Please refer to Figure 8 and Fig. 9 The limiting structure 500 includes an arc-shaped limiting groove 501 and a torsion spring 502. The arc-shaped limiting groove 501 is provided on both sides of the anti-thrombotic pump 1. The torsion spring 502 is fixedly connected between the first swing plate 401 and the second swing plate 402.

[0049] When the top of the antithrombotic pump 1 is pressed by the outside world, the antithrombotic pump 1 bears the pressure and drives the first swing plate 401 and the second swing plate 402 to swing, and due to the limitation of the torsion spring 502, it can only swing a small distance. When the antithrombotic pump 1 is not under pressure, due to the characteristics of the torsion spring 502 itself, the first swing plate 401 and the second swing plate 402 can be reset, thereby improving practicality;

[0050] In order to stably place the antithrombotic pump 1 when it is not in use, the following specific structures need to be disclosed in detail: the first rotating disk 301, the first rotating shaft 302 and the first arc plate 303 are symmetrically arranged in two groups along the transverse center of the antithrombotic pump 1, and the second rotating disk 304, the second rotating shaft 305 and the second arc plate 306 on the inner side wall of the antithrombotic pump 1 are symmetrically arranged in two groups along the transverse center of the antithrombotic pump 1;

[0051] When the antithrombotic pump 1 is not in use, the staff manually rotates the first rotating disk 301 clockwise and the second rotating disk 304 counterclockwise, and drives the first rotating shaft 302 and the second rotating shaft 305 to reset and rotate, so that the first curved plate 303 and the second curved plate 306 are "U-shaped" and the two groups of the first curved plates 303 and the second curved plates 306 are higher than the antithrombotic pump 1, so that the two groups of the first curved plates 303 and the second curved plates 306 can better support the antithrombotic pump 1 when it is placed, and can also keep the antithrombotic pump 1 away from the desktop;

[0052] In order to lift the anti-thrombotic pump 1 when the anti-thrombotic pump 1 is not in use, the following specific structure needs to be disclosed in detail, please refer to Figure 5 The first swing plate 401, the second swing plate 402, the first limit shaft 403 and the second limit shaft 404 are symmetrically arranged in two groups along the transverse center of the anti-thrombotic pump 1, and the third swing plate 405, the third limit shaft 406, the fourth limit shaft 407 and the fourth swing plate 408 on the inner side wall of the anti-thrombotic pump 1 are symmetrically arranged in two groups along the transverse center of the anti-thrombotic pump 1;

[0053] When the first rotating shaft 302 and the second rotating shaft 305 are rotated to reset, the first swing plate 401 and the third swing plate 405 are driven to reset and swing inwards, and the second swing plate 402 and the fourth swing plate 408 are driven to reset and swing inwards around the first limiting shaft 403 and the fourth limiting shaft 407, and finally the first swing plate 401 and the third swing plate 405 are driven to reset and swing inwards. Figure 6 , thereby preventing the anti-thrombotic pump 1 from being damaged by water stains or dust when it is placed for a long time, thereby improving practicality.
