Description

Technical Field

[0001] The present invention belongs to the technical field of medical care air pressure pumps, and specifically relates to an automatic disinfection type air pressure pump. Background Art

[0002] In the field of modern medical care, the prevention and care of venous thromboembolism (VTE) are of great importance. VTE includes deep vein thrombosis and pulmonary embolism, which seriously threaten the health and life safety of patients. Among them, the limb air pressure therapeutic apparatus, as one of the important devices for VTE care, promotes venous blood return and reduces blood viscosity by periodically inflating and pressurizing the patient's limbs, thereby effectively preventing the occurrence of VTE and being widely used in clinical care. However, during its frequent use, the problem of hygiene and safety has gradually emerged. In the medical environment, especially in places such as hospital wards and operating rooms, the air pressure pump is used to provide adjuvant treatment for patients. Once bacteria and viruses breed inside the air pressure pump, during the process of gas transmission and discharge, these pathogens are extremely likely to be discharged from the air pressure pump into the air along with the air flow, making it easy for patients during care to inhale the pathogens, leading to cross-infection and seriously threatening the health and life safety of patients. According to relevant medical statistical data, nosocomial infection incidents caused by the hygiene problems of medical devices occur from time to time, and some of them are related to the contamination of the air pressure pump, bringing additional pain to patients and also increasing the medical burden. Therefore, it is crucial to disinfect the air pressure pump.

[0003] Traditional air pressure pumps generally lack effective disinfection measures. Most of them are to manually disassemble the bushing regularly and then clean the bushing and the interior of the device separately. This not only takes time and effort, but also may increase the probability of errors due to the cumbersome operation, and it is difficult to ensure that each cleaning can be done comprehensively and without dead ends, resulting in low efficiency.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] Through the cooperation of structures such as small holes and push plates, the present invention facilitates the disinfection of the inner wall of the cavity and the airbag. The piston rod of the air cylinder squeezes the trigger plate, driving the connecting plate to move in the first chute in the direction close to the first spring, squeezing the first spring and compressing the space inside the first chute. By compressing the space, the air pressure inside the first chute increases, and the gas in the first chute moves through the ventilation pipe in the direction close to the push plate, and the push plate is squeezed by the air pressure to move in the direction close to the second spring, squeezing the second spring and applying pressure to the disinfectant liquid in the disinfection chamber. When the connecting plate moves in the direction close to the first spring, it will drive the rack to move, causing the meshing gear to rotate. When the small hole on the gear rotates to the position aligned with the liquid outlet hole, the disinfectant liquid in the disinfection chamber will enter the cavity interior through the liquid outlet hole, small hole and atomization of the atomizing nozzle under the action of air pressure and the thrust of the push plate. After energy storage and release, the disinfectant liquid can be evenly distributed in the cavity in the form of tiny particles, and under the action of pressure, it is beneficial to achieve comprehensive coverage disinfection. At the same time, when the piston rod moves in the direction close to the exhaust valve, the atomized disinfectant liquid can enter the contact layer through the disinfection pipe and be sprayed out through the ventilation holes on the contact layer to disinfect the inner wall of the bushing and the surface of the contact layer, effectively avoiding the possible disinfection blind spots of the traditional disinfection method. At the same time, there is no need for manual disinfection of the interior of the cavity, and the inner wall of the cavity and the airbag are automatically disinfected, reducing the manual cleaning cost;

[0019] Through the cooperation of structures such as a disinfection chamber and an ultraviolet emitter, the present invention improves the disinfection effect of the device. The disinfectant liquid and the ultraviolet emitter in the disinfection chamber have different bactericidal mechanisms. The disinfectant liquid usually destroys the structures of bacteria and viruses through chemical reactions. For example, chlorine-containing disinfectants can oxidize biological macromolecules such as proteins and nucleic acids of microorganisms, while ultraviolet rays mainly destroy the DNA or RNA structures of microorganisms to prevent their replication and reproduction. When used in combination, they can attack microorganisms from multiple angles, making the bactericidal effect more comprehensive and thorough, shortening the disinfection time, and further improving the disinfection efficiency of the device;

[0020] Through the cooperation of structures such as a clamping block and a clamping groove, the present invention facilitates the cleaning or replacement of the atomizing nozzle. After disinfection, medical staff can pull the handle away from the cavity, driving the clamping block to move away from the sliding plate, so that the clamping block disengages from the clamping groove and compresses the third spring. Then, the sliding plate is pulled out upward to clean or replace the atomizing nozzle on the sliding plate, which is convenient for maintaining the atomizing nozzle and avoiding the situation that impurities such as crystallized disinfectant liquid, dirt, or microorganisms remaining on the surface of the atomizing nozzle affect the atomizing disinfection effect, enabling the atomizing nozzle to stably disinfect the interior of the cavity and facilitating operation at the same time.

An airbag 204 is installed on the side of the piston rod 203 away from the cylinder 202. An intake valve 205 and an exhaust valve 206 are provided at the end of the cavity 201 away from the cylinder 202. A tail pipe 207 is installed on the side of the exhaust valve 206 away from the cavity 201. A first chute 208, a second chute 209 and a third chute 210 are respectively formed inside the cavity 201.

[0039] Adopting the above solution: By setting the cooperation of structures such as the small hole 106 and the push plate 303, it is convenient to disinfect the inner wall of the cavity 201 and the airbag 204. The piston rod 203 is driven by the air cylinder 202 to squeeze the trigger plate 101, driving the connecting plate 102 to move in the first chute 208 towards the direction close to the first spring 103, squeezing the first spring 103 and compressing the space inside the first chute 208.

The movement of the connecting plate 102 towards the direction close to the first spring 103 will drive the rack 104 to move, causing the meshing gear 105 to rotate. When the small hole 106 on the gear 105 rotates to the position aligned with the liquid outlet hole 305, the disinfectant liquid in the disinfection chamber 301 will enter the inside of the cavity 201 through the liquid outlet hole 305, the small hole 106, and the atomizing nozzle 108 for atomization. After energy storage and release, the disinfectant liquid can be evenly distributed in the cavity 201 in the form of tiny particles, and under the action of pressure, it is conducive to achieving comprehensive coverage disinfection. At the same time, 202 makes the piston rod 203 move towards the direction close to the exhaust valve 206, so that the atomized disinfectant liquid in the cavity 201 can enter the contact layer 213 through the disinfection pipe 211 and be sprayed out through the air holes on the contact layer 213 to disinfect the inner wall of the bushing 212 and the surface of the contact layer 213, effectively avoiding the possible disinfection blind spots of the traditional disinfection method. At the same time, there is no need for manual disinfection of the inside of the cavity 201, and the inner wall of the cavity 201 and the airbag 204 are automatically disinfected, reducing the manual cleaning cost.

[0040] As Figures 4 to 8 shown, the intake valve 205 is located on the side of the exhaust valve 206. The piston rod 203 is slidably connected to the inner wall of the cavity 201. The airbag 204 is located between the piston rod 203 and the exhaust valve 206. The connecting plate 102 is slidably connected to the first chute 208. The connecting plate 102 is elastically connected to the inner wall of the first chute 208 through the first spring 103. The trigger plate 101 penetrates the inner wall of the first chute 208 and extends to the inner wall of the cavity 201. The trigger plate 101 is located between the air cylinder 202 and the piston rod 203. The slide plate 107 is slidably connected to the second chute 209. The top of the slide plate 107 penetrates the inner wall of the second chute 209 and extends above the cavity 201. The gear 105 is rotatably connected to the inside of the cavity 201. The exhaust pipe 207 and the air cylinder 202 respectively penetrate the inner wall of the therapeutic instrument housing 5 and extend to both sides of the therapeutic instrument housing 5. One end of the exhaust pipe 207 away from the cavity 201 is connected to a limb bushing.

[0041] One side of the disinfection chamber 301 away from the ventilation pipe 306 is fixedly connected to the side surface of the chamber 201. The push plate 303 is elastically connected to the surface of the chamber 201 through the second spring 304. The inside of the chamber 201 communicates with the inside of the disinfection chamber 301 through the liquid outlet hole 305. The ventilation pipe 306 is located on the side of the push plate 303 away from the second spring 304. The inside of the disinfection chamber 301 communicates with the inside of the first chute 208 through the ventilation pipe 306. The size of the atomizing nozzle 108 is adapted to the size of the liquid outlet hole 305, and the atomizing nozzle 108 is aligned with the liquid outlet hole 305. The gear 105 is located between the disinfection chamber 301 and the slide plate 107. An operation area and a disinfectant liquid inlet are provided on the treatment instrument housing 5.

An air inlet hole is provided on the side surface of the treatment instrument housing 5, and the air inlet hole on the treatment instrument housing 5 communicates with the air inlet valve 205.

[0042] A fixing mechanism 4 is arranged inside the main body mechanism 2. The fixing mechanism 4 is located on the side of the triggering mechanism 1. The fixing mechanism 4 includes a handle 401. A third spring 402 and a clamping block 403 are fixedly connected to the handle 401. The clamping block 403 is slidably connected to the inside of the chamber 201. The clamping block 403 is clamped with the clamping groove 109. The handle 401 is elastically connected to the inner wall of the third chute 210 through the third spring 402. One end of the handle 401 away from the clamping block 403 penetrates through the inner wall of the chamber 201 and extends to the side of the chamber 201 close to the cylinder 202. The handle 401 is located above the ventilation pipe 306. The top of the clamping block 403 is provided with an inclined surface.

[0043] Adopting the above scheme: Through the cooperation of structures such as the disinfection chamber 301 and the ultraviolet emitter 307, the disinfection effect of the device is improved. The disinfectant liquid and the ultraviolet emitter 307 in the disinfection chamber 301 have different sterilization mechanisms. The disinfectant liquid usually destroys the structures of bacteria and viruses through chemical reactions. For example, chlorine-containing disinfectants can oxidize biological macromolecules such as proteins and nucleic acids of microorganisms, while ultraviolet rays mainly destroy the DNA or RNA structures of microorganisms and prevent their replication and reproduction. When the two are used in combination, microorganisms can be attacked from multiple angles, making the sterilization effect more comprehensive and thorough, while shortening the disinfection time and further improving the disinfection efficiency of the device;

[0044] By setting up the cooperation of structures such as the clamping block 403 and the clamping groove 109, it is convenient to clean or replace the atomizing nozzle 108. After disinfection is completed, the medical staff can pull the handle 401 in the direction away from the cavity 201, driving the clamping block 403 to move in the direction away from the sliding plate 107, so that the clamping block 403 is disengaged from the clamping groove 109 and compresses the third spring 402. Then, the sliding plate 107 is pulled out upward to clean or replace the atomizing nozzle 108 on the sliding plate 107, which is convenient for maintaining the atomizing nozzle 108 and avoiding the situation that impurities such as crystallized disinfectant, dirt or microorganisms remaining on the surface of the atomizing nozzle 108 affect the atomizing disinfection effect, enabling the atomizing nozzle 108 to stably disinfect the inside of the cavity 201 while being convenient for operation.

[0045] The working principle and usage process of the present invention: First, after the device is used, the liquid inlet valve 302 is opened to inject disinfectant into the disinfection chamber 301 and then the liquid inlet valve 302 is closed. Subsequently, the piston rod 203 is moved in the direction close to the trigger plate 101 through the air cylinder 202. When the piston rod 203 abuts against the trigger plate 101, it will squeeze the trigger plate 101 to drive the connecting plate 102 to move in the first sliding groove 208 in the direction close to the first spring 103, squeezing the first spring 103 and compressing the space inside the first sliding groove 208. By compressing the space, the air pressure inside the first sliding groove 208 increases, and the gas inside the first sliding groove 208 moves in the direction close to the push plate 303 through the air pipe 306, and the push plate 303 is squeezed by the air pressure to move in the direction close to the second spring 304, squeezing the second spring 304 and applying pressure to the disinfectant in the disinfection chamber 301. Also, since the small hole 106 on the gear 105 is not aligned with the liquid outlet hole 305 and the liquid inlet valve 302 is closed, the disinfection chamber 301 is in a sealed state at this time, so the air pressure inside the disinfection chamber 301 increases through squeezing;

[0046] When the connecting plate 102 moves towards the direction close to the first spring 103, it will drive the rack 104 to move, causing the meshing gear 105 to rotate. When the small hole 106 on the gear 105 rotates to the position aligned with the liquid outlet hole 305, the disinfectant liquid in the disinfection chamber 301 will enter the interior of the cavity 201 through the liquid outlet hole 305, the small hole 106 and the atomizing nozzle 108 under the action of air pressure and the thrust of the push plate 303. When the disinfectant liquid passes through the atomizing nozzle 108, it will be atomized and sprayed inside the cavity 201 under the action of pressure to automatically disinfect the inner wall of the cavity 201 and the airbag 204. At the same time, the ultraviolet emitter 307 is activated to emit ultraviolet rays to further disinfect the inner wall of the cavity 201, improving the disinfection effect of the device. At the same time, 202 causes the piston rod 203 to move towards the direction close to the exhaust valve 206, enabling the atomized disinfectant liquid in the cavity 201 to enter the contact layer 213 through the disinfection pipe 211 and be ejected through the air holes on the contact layer 213 to disinfect the inner wall of the bushing 212 and the surface of the contact layer 213;

[0047] After the disinfection is completed, the medical staff can pull the handle 401 away from the cavity 201, driving the clamping block 403 to move away from the slide plate 107, so that the clamping block 403 is disengaged from the clamping groove 109 and compresses the third spring 402. Then, after pulling out the slide plate 107 upward, the atomizing nozzle 108 on the slide plate 107 can be cleaned or replaced, avoiding the influence of the crystallization of the residual disinfectant on the atomizing nozzle 108 on its atomizing effect, thereby indirectly reducing the disinfection effect.
