Description

Technical Field

[0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a cardiac end compression hemostasis device used in cardiology. Background Art

[0002] Cardiology, also known as cardiovascular medicine, is a clinical department set up by the general internal medicine department of hospitals at all levels for the diagnosis and treatment of cardiovascular diseases. The diseases treated include angina pectoris, hypertension, sudden death, arrhythmia, heart failure, premature beats, arrhythmia, myocardial infarction, cardiomyopathy, myocarditis, acute myocardial infarction and other cardiovascular diseases. After cardiology surgery, the puncture catheter and sheath of the femoral artery must be removed from the artery. At this time, a compression hemostasis device is required to accurately press the puncture site for a long time and intermittently release the buffer to ensure the necessary blood supply needs. In order to avoid the occurrence of high blood pressure, the cardiology department uses a compression hemostasis device for compression hemostasis;

[0003] However, after using a compression hemostasis device for compression, appropriate decompression is usually required in about half an hour to an hour. However, when medical staff are busy, they may not perform decompression on the compressed wound in time, causing the compression hemostasis time to be too long, resulting in obstructed blood circulation, causing tissue necrosis or infection complications and other symptoms, thereby aggravating the patient's condition and increasing medical pressure. In addition, for patients with large amounts of wound bleeding, the required compression time is longer, thereby increasing the probability of infection at the wound.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a cardiac compression hemostasis device for use in cardiology, which compresses and stops bleeding on the patient's arterial wound through a hemostasis compression pad. When the compression and hemostasis reaches a specified time range and requires decompression and buffering, the output end of the micro-electric telescopic rod contracts. Since one side of the top of the limit block is an inclined surface, the limit block automatically contracts toward the inside of the second cavity. At this time, the elastic force of the first spring acts on the baffle, and the second piston is driven to contract inside the contraction cavity through the first connecting rod, so that the hemostasis compression pad automatically releases part of the pressure to ensure the necessary blood supply demand, avoiding the situation where medical staff are too busy to decompress in time, resulting in obstruction of blood circulation at the arterial wound, causing tissue necrosis or infection and causing complications. The cooling water circulates and refluxes inside the cooling channel and the reflux pipe, thereby accelerating the hemostasis and healing of the arterial wound and improving the compression and hemostasis efficiency.

[0019] Compared with the prior art, the present invention provides a cardiac compression hemostasis device used in cardiology, which has the following beneficial effects:

[0020] 1. The present invention uses a hemostatic compression pad to compress and stop bleeding on the patient's arterial wound. When the compression and hemostasis reaches a specified time range and decompression and buffering are required, the output end of the micro-electric telescopic rod is contracted. Since one side of the top of the limit block is an inclined surface, the limit block automatically contracts toward the inside of the second cavity. At this time, the elastic force of the first spring acts on the baffle, and the second piston is driven to contract inside the contraction cavity through the first connecting rod, so that the hemostatic compression pad automatically releases part of the pressure to ensure the necessary blood supply demand, thereby avoiding the situation where medical staff are too busy to decompress in time, resulting in obstruction of blood circulation at the arterial wound, causing tissue necrosis or infection and causing complications.

[0021] 2. The present invention can drive the limit block to contract and slide out of the limit opening to release the limit effect through the contraction of the output end of the micro-electric telescopic rod. There are multiple groups of limit openings. Patients with different amounts of bleeding require different pressure reductions. When the second piston slowly moves backward under the action of the sealing friction force, the micro-electric telescopic rod drives the limit block to slide into the limit openings with different distances, so that the baffle moves a specified distance to release a specified pressure value, so that the hemostatic compression pad releases the specified pressure value on the arterial wound of patients with different amounts of bleeding, which is more conducive to the hemostasis recovery of the wound of patients with different amounts of bleeding.

[0022] 3. When the present invention compresses the patient's arterial wound with the hemostatic compression pad, if there is bleeding at the wound when the sheath is pulled out, the patient's wound is bleeding heavily. While appropriately increasing the compression strength of the hemostatic compression pad, a syringe is inserted through the rubber sealing plug, and a coolant is injected into the interior of the cooling channel through the opening. The coolant refluxes inside the cooling channel and the reflux pipe to cool the patient's wound, causing blood vessels to contract, accelerating the hemostasis of the wound, and reducing the compression time of the hemostatic compression pad, thereby reducing the situation in which patients with heavy bleeding wounds need too long compression time and may be infected.

DETAILED DESCRIPTION

[0037] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a cardiac compression hemostasis device for use in cardiology.

[0039] A cooling channel 301 is provided inside the hemostatic compression pad 3, and the cooling channel 301 is arranged in a circular shape. A return pipe 302 is fixedly installed on the other side of the top of the hemostatic compression pad 3, and the return pipe 302 is connected with the front end and the rear end of the other side of the cooling channel 301. An opening 303 is provided at the front end of the other side of the hemostatic compression pad 3, and the opening 303 is connected with the cooling channel 301. A rubber sealing plug 304 is movably installed inside the opening 303.

[0040] A pressure fine-tuning mechanism 4 is provided at the bottom of the threaded rod 203, a first cavity 401 is provided at the other end of the threaded rod 203, a first spring 402 is fixedly installed on the other side of the first cavity 401, and the first spring 402 is sleeved on the outside of the first connecting rod 207, a baffle 403 fixedly connected to one end of the first spring 402 is fixedly installed on the outside of the first connecting rod 207, a micro-electric telescopic rod 404 is fixedly installed inside the pressure fine-tuning mechanism 4, a limiting opening 405 is provided at the bottom of the first cavity 401, a second cavity 406 is provided at the output end of the micro-electric telescopic rod 404, a second spring 407 is fixedly installed inside the second cavity 406, a limiting block 408 extending to the outside is fixedly installed on the top of the second spring 407, the limiting block 408 passes through the limiting opening 405 and extends to the inside of the first cavity 401, and the limiting block 408 is located on one side of the bottom of the baffle 403.

[0041] Furthermore, a compression cylinder 105 is fixedly installed at the bottom of the compression hemostasis device body 1, and a pressurizing channel 106 is opened on the other side of the compression hemostasis device body 1, and the pressurizing channel 106 is connected with the compression cylinder 105 and the pressure regulating chamber 201, and a pressurizing column 107 is movably installed inside the compression cylinder 105, and the bottom of the pressurizing column 107 is fixedly connected to the hemostasis compression pad 3;

[0042] Specifically, the medical staff rotates the storage cylinder 202 to make the threaded rod 203 extend outward through the threaded connection inside the storage cylinder 202, thereby driving the first piston 204 to move to the other side inside the pressure regulating chamber 201, and pressurizing the inside of the compression cylinder 105 through the pressurizing channel 106, so that the pressurizing column 107 drives the hemostatic compression pad 3 to move downward to compress and stop bleeding on the patient's arterial wound. When the compression and hemostasis are within the specified time range and decompression and buffering are required, the output end of the micro-electric telescopic rod 404 is contracted. Since one side of the top of the limit block 408 is an inclined surface, the limit block 408 automatically contracts toward the inside of the second cavity 406. At this time, the elastic force of the first spring 402 acts on the baffle 403, and the second piston 206 is driven to contract inside the contraction cavity 205 through the first connecting rod 207, so that the hemostatic compression pad 3 automatically releases part of the pressure, thereby ensuring the necessary blood supply needs and avoiding the arterial wound caused by the medical staff being too busy to decompress in time. The blood circulation at the wound is blocked, causing tissue necrosis or infection, which may cause complications. Different pressures are required for decompression for patients with different amounts of bleeding. When the second piston 206 moves slowly backward under the action of the sealing friction force, the micro-electric telescopic rod 404 drives the limit block 408 to slide into the limit opening 405 with different distances, so that the baffle 403 moves a specified distance to release a specified pressure value, so that the hemostatic compression pad 3 releases the specified pressure value for the arterial wound of patients with different amounts of bleeding, which is more conducive to the recovery of hemostasis at the wound of patients with different amounts of bleeding. The rubber sealing plug 304 is penetrated by a syringe, and the cooling liquid is injected into the cooling channel 301 through the opening 303. The cooling liquid refluxes in the cooling channel 301 and the reflux pipe 302, cools the patient's wound, causes blood vessels to contract, accelerates the hemostasis of the wound, and reduces the compression time of the hemostatic compression pad 3, thereby reducing the situation in which patients with heavy bleeding wounds need to be compressed for too long and may be infected.

[0043] Furthermore, through slots 101 are provided at the front and rear ends of the compression hemostasis device body 1, and a binding band 102 is fixedly installed and wrapped inside the rear end through slot 101, and the number of the limiting openings 405 is four groups, and one side of the top of the limiting block 408 is an inclined surface;

[0044] Furthermore, a mother Velcro 103 is fixedly installed at the bottom of the strap 102, and a child Velcro 104 is fixedly installed at the front outer side of the strap 102, and the mother Velcro 103 and the child Velcro 104 cooperate to adhere to each other;

[0045] Specifically, after the medical staff completes the first compression hemostasis operation on the patient's arterial wound, one end of the bandage 102 passes through the through slot 101, and then the sub-velcro 104 covers the bottom of the main Velcro 103 for adhesion, so that the bandage 102 fixes the compression hemostasis device body 1 on the patient's wrist for hemostasis compression, which is convenient for the medical staff to operate;

[0046] Furthermore, a transparent window 108 is provided on the top of the compression hemostasis device body 1, and the transparent window 108 is on the same vertical line as the compression cylinder 105, pressure scale lines 109 are evenly distributed on the top of the hemostasis pressure regulating mechanism 2, and a sheath arc opening 308 is opened on one side of the bottom of the hemostasis compression pad 3;

[0047] Specifically, the medical staff can observe the position of the arc-shaped opening 308 of the sheath tube at the bottom of the hemostatic compression pad 3 through the transparent window 108, so that the arterial puncture sheath tube is located inside the arc-shaped opening 308 of the sheath tube, thereby reducing the pressure force of the hemostatic compression pad 3 on the sheath tube, minimizing the damage to the wound when the sheath tube is pulled out, and the pressure scale line 109 is convenient for the medical staff to observe the pressure intensity value inside the compression cylinder 105, so that it is easier to adjust the specified compression force to perform compression hemostasis operation;

[0048] Furthermore, a knob 208 is fixedly mounted at one end of the storage tube 202, a first groove 209 is opened on one side of the knob 208, a button 210 is movably mounted inside the first groove 209, and a first connecting rod 207 passes through the storage tube 202 and the knob 208 and extends to the inside of the first groove 209;

[0049] Specifically, when the device is not in use, the threaded rod 203 is retracted into the storage tube 202, driving the first connecting rod 207 to penetrate the storage tube 202 and the knob 208 and extend to the inside of the first groove 209. At this time, the first groove 209 is located on the other side of the button 210 to lift the button 210. By pressing the button 210, the baffle 403 moves to the other end inside the first cavity 401. During the movement of the baffle 403, the bottom squeezes the limit block 408. Since the top of the limit block 408 is an inclined surface, the limit block 408 automatically retracts into the second cavity 406. Then the output end of the micro electric telescopic rod 404 extends, driving the limit block 408 moves to the other end. If the limit block 408 is located in the limit opening 405 close to one side, the button 210 is intermittently pressed to make the limit blocks 408 slide into the limit opening 405 on the other side one by one under the elastic force of the second spring 407. When the limit block 408 slides into the limit opening 405 closest to the other side, the button 210 is continuously pressed to move the baffle 403 to the other side of the limit block 408. Subsequently, the limit block 408 is reset under the elastic force of the second spring 407 to limit the baffle 403, so that the second piston 206 moves to the other side inside the contraction chamber 205, so that the decompression operation can be automatically performed when the device is used again.

[0050] Furthermore, a second groove 211 is formed at the top and bottom of the other side of the second piston 206, and a fixing block 212 is installed at the top and bottom of the other side of the inner wall of the contraction chamber 205, and the fixing block 212 extends to the inside of the second groove 211;

[0051] Furthermore, a first slide groove 213 is formed at the front and rear ends of the threaded rod 203, a fixing plate 214 is installed at one side of the pressure regulating chamber 201, a first slider 215 is fixedly installed at the front and rear ends of the inner side of the fixing plate 214, and the first slider 215 is movably installed inside the first slide groove 213;

[0052] Specifically, when the second piston 206 moves to the other side inside the contraction chamber 205, the fixing block 212 slides into the second groove 211 to limit the second piston 206, so as to prevent the second piston 206 from sliding out of the contraction chamber 205 and affecting the normal use of the device. When the threaded rod 203 moves inside the storage tube 202, the first sliding block 215 slides inside the first sliding groove 213, so as to prevent the threaded rod 203 from rotating together with the storage tube 202, so as to prevent the threaded rod 203 from being unable to drive the first piston 204 to move inside the pressure regulating chamber 201.

[0053] Furthermore, a second slide groove 305 is provided at the front and rear ends of the outer side of the compression cylinder 105, a second connecting rod 306 is fixedly installed at the front and rear ends of the hemostatic compression pad 3, a second slider 307 is fixedly connected to the top of the second connecting rod 306, and the second slider 307 is movably installed inside the second slide groove 305;

[0054] Specifically, when the hemostatic compression pad 3 moves at the bottom of the compression hemostatic device body 1, the second connecting rod 306 connects the second slider 307 to drive it to slide inside the second slide groove 305, so that the hemostatic compression pad 3 moves more stably, avoiding the shaking of the hemostatic compression pad 3 and causing the compression point to be inaccurate during compression;

[0055] Furthermore, the compression hemostasis device body 1 includes a compression timing mechanism 5, a timer 501 is fixedly installed on the top of the compression hemostasis device body 1, a third cavity 502 is opened inside the rear end of the compression hemostasis device body 1, a speaker 503 is fixedly installed inside the third cavity 502, and the timer 501 is electrically connected to the speaker 503, and sound expansion holes 504 are evenly opened on the top of the compression hemostasis device body 1, and the sound expansion holes 504 are located on the top of the speaker 503;

[0056] Specifically, after the medical staff completes the arterial puncture compression hemostasis operation, they set the compression time through the timer 501 according to whether the patient has severe bleeding. When the set compression time is reached, the speaker 503 sends a reminder through the sound amplification hole 504, "Please reduce pressure and buffer appropriately" to remind the medical staff, so as to prevent the medical staff from forgetting the set time and causing the arterial puncture wound compression time process to cause symptoms such as infection at the wound (the timer 501 is a prior art, and the connection relationship between the timer 501 and the speaker 503 is an existing circuit control technology, which is common knowledge of technicians in this field and will not be elaborated on here).

[0057] Working principle: First, the staff places the compression hemostasis device body 1 on the upper end of the patient's wrist artery, then observes the position of the arterial wound through the transparent window 108, aligns the sheath tube arc-shaped opening 308 with the sheath tube, and rotates the storage tube 202 through the knob 208. Since the threaded rod 203 is threadedly connected to the inner wall of the storage tube 202, the threaded rod 203 drives the first piston 204 to move to the other end inside the pressure regulating chamber 201. At this time, the first slider 215 slides inside the first slide groove 213, and pressure is applied to the inside of the compression tube 105 through the pressurizing channel 106. By observing the pressure scale line 109, it is adjusted to a suitable pressure value, and the pressurizing column 107 The compression tube 105 moves downward inside, driving the hemostatic compression pad 3 to move downward to compress the patient's arterial puncture wound, so that the sheath is located inside the sheath arc-shaped opening 308. Then, after the front end of the binding band 102 passes through the through slot 101, the compression hemostasis device body 1 is fixedly worn on the patient's wrist through the child Velcro 104 and the mother Velcro 103. Then, the sheath is pulled out, and cooling water is injected into the cooling channel 301 through the rubber sealing plug 304 through the syringe, so that the blood vessel is cooled and contracted, and the hemostasis and healing of the wound are accelerated. Then, the medical staff puts their fingers on the distal end of the radial artery to feel whether there is a pulse to properly adjust the compression force of the hemostatic compression pad 3.

[0058] The compression time is set by the timer 501. When the specified compression time is reached, a reminder sound "Please reduce pressure and buffer appropriately" is issued through the speaker 503 to remind the medical staff to reduce pressure. If the medical staff is busy and fails to perform appropriate decompression operations in time, the output end of the micro-electric telescopic rod 404 will shrink, driving the limit block 408 to move to one side, and shrink a suitable distance according to the set time, so that the elastic force of the second spring 407 acts on the limit block 408 to slide into the limit opening 405 of a suitable distance. Then the elastic force of the first spring 402 acts on the baffle 403, so that the first connecting rod 207 drives the second piston 206 to shrink inside the contraction chamber 205, and the pressure inside the compression cylinder 105 is reduced and buffered, so as to avoid the situation where the medical staff fails to reduce pressure and buffer the arterial wound in time, resulting in blood circulation or infection in the wound.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
