Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular is a multifunctional atomization medication suction and cleaning device. Background Art

[0002] Traditional sputum suction devices are mainly divided into electric multifunctional negative pressure sputum suction devices and simple manual sputum suction devices. These devices are widely used in medical work and are suitable for timely sputum suction treatment when there is respiratory mucus or vomiting in hospitals or homes.

[0003] The functions of traditional sputum suction devices are relatively simple, mainly focusing on sputum suction operations, and it is impossible to provide medication treatment while suctioning sputum. In view of the limitations of traditional sputum suction devices, the medical field has proposed a multifunctional atomization medication suction device that can achieve atomization medication function while suctioning sputum, which can improve the treatment effect and reduce the patient's pain.

[0004] When using the multifunctional atomizing drug administration and sputum suction cleaning device, the sputum suction part needs to be extended into the patient's throat for negative pressure suction. In order to reduce the discomfort of the patient's sputum suction, the radius of the pipe that accommodates the sputum should not be set too large. In addition, the viscosity of the respiratory tract of the patient varies. When the thicker sputum passes through a channel with a smaller radius, the friction with the pipe and the smaller diameter of the pipe will inevitably cause the thick sputum to remain in the pipe. Then, when the medical staff removes the pipe, it is easy to cause the sputum to fall back into the patient's respiratory tract, which affects the patient's comfort and the efficiency of sputum suction. For this reason, it is necessary to propose a multifunctional atomizing drug administration and sputum suction cleaning device that can reduce the consumption of sputum suction driving force and reduce the sputum from falling from the suction tube back into the patient's body. Summary of the invention

[0005] In order to solve the above-mentioned problems, the purpose of the present invention is to provide a multifunctional atomization drug administration and sputum suction cleaning device. By setting an inner tube and an outer tube, the separation of atomization drug administration and sputum suction is realized, the gap between the inner tube and the outer tube is used as the absorption and storage space for sputum, and a protrusion is set in the gap to increase the adhesion effect of sputum and reduce the probability of sputum falling out.

[0006] In order to achieve the above-mentioned object, the technical scheme of the present invention is as follows: a multifunctional atomization medication suction and cleaning device, comprising an insertion tube, one end of the insertion tube is connected to a driving part for atomizing medication and providing a sputum suction driving force, and one end of the insertion tube away from the driving part is fixedly connected to an operating head for releasing atomized liquid and sucking sputum;

[0007] The insertion tube includes an outer tube and an inner tube. The outer tube is sleeved on the outside of the inner tube and a gap is provided between the inner tube for sputum to pass through. An end of the outer tube close to the operating head is provided with a support block with an annular structure. The support block is located in the gap between the outer tube and the inner tube. The inner and outer side walls of the support block are respectively fixedly connected to the inner tube and the outer tube. A plurality of sputum holes for sputum to pass through are opened on the support block. Check valves are fixedly connected in the sputum holes. A protrusion with a threaded structure is provided on the inner wall of the outer tube.

[0008] The principle of the basic solution is: the operating head is brought to the patient's throat through the insertion tube, the driving part is used to atomize the medicine, provide the driving force for the release of the atomized medicine and provide the negative pressure for suction driving, the inner tube is used as the channel for the atomized medicine, the gap between the outer tube and the inner tube is used as the channel for sputum suction, and the backflow of sputum is limited through the sputum hole.

[0009] The beneficial effects of the basic scheme are: 1. By setting the gap between the inner tube and the outer tube as a channel and storage space for sputum suction, the driving force required to suck the sputum out of the tube is reduced, thereby improving the sputum suction efficiency.

[0010] 2. Due to the different respiratory conditions of different patients, there are sputums with different viscosities. By setting the protrusions of the threaded structure, the friction between the sputum with high viscosity and the inner wall of the outer tube is increased, and the probability of the sputum being thrown out of the gap and falling back into the patient's respiratory tract when the insertion tube is taken out due to the small friction is reduced.

[0011] 3. When the inner tube and the outer tube are in the patient's throat, the patient's swallowing action will exert inward deformation pressure on the outer tube. By setting the support block and the check valve, on the one hand, the probability of squeezing sputum out of the gap due to the reduction in the volume of the gap between the inner tube and the outer tube can be reduced. On the other hand, the sputum hole for sputum to enter the gap can be kept from being squeezed and deformed, reducing the problem of the operating head losing its suction effect due to the squeezing force of swallowing and reducing the suction efficiency.

[0012] Furthermore, the operating head includes a mist outlet head and a sputum suction head, the sputum suction head is wrapped outside the mist outlet head, the mist outlet head is detachably connected to the end of the inner tube, the sputum suction head is detachably connected to the end of the outer tube, the gap between the sputum suction head and the mist outlet head is connected to the gap between the outer tube and the inner tube, a plurality of mist outlet holes for spraying atomized medicine liquid are provided on the mist outlet head, the inner walls of the mist outlet holes are fixedly connected with a first one-way air valve, and a plurality of sputum suction holes for sputum to pass through are provided on the sputum suction head.

[0013] The beneficial effects of the basic scheme are: due to the negative pressure of sputum suction, sputum will move into the tube, and there is a possibility of entering the inner tube, overflowing through the mist outlet to perform atomized medication to the patient's respiratory system. By setting a first one-way air valve, the probability of sputum entering the inner tube through the mist outlet hole during the sputum suction stage can be reduced, reducing the secondary contamination of the inner tube by sputum and reducing the need for subsequent cleaning of the inner tube.

[0014] Further, the driving part includes a driving box and an intelligent system, the intelligent system is connected to the driving box signal, the inner tube and the outer tube are away from the mist outlet and one end thereof passes through the side wall of the driving box and extends into the driving box, one end of the inner tube located in the driving box passes through the side wall of the outer tube and is connected to an atomizing component for atomizing the liquid medicine, and one end of the outer tube located in the driving box is connected to a sputum suction component for providing a negative pressure drive for sputum suction;

[0015] A drug feeding port is provided on the top of the driving box, the drug feeding port is detachably connected with a drug feeding cover, a sealing ring is detachably connected at the connection between the drug feeding cover and the drug feeding port, a drug feeding pipe is fixedly connected to the bottom of the drug feeding port, and one end of the drug feeding pipe away from the drug feeding port is fixedly connected with a drug storage tank.

[0016] The beneficial effects of the basic scheme are: since the atomized medicine liquid is a mist liquid, by setting a sealing ring, on the one hand, it can reduce the contamination of the medicine liquid by air during the process, and on the other hand, maintain the airtightness of the drive box, reduce the problem of the atomized medicine liquid overflowing into the drive box, and improve the efficiency of atomization drug delivery.

[0017] Furthermore, a temperature sensor and a heating plate are fixedly connected to the inner wall of the medicine storage tank.

[0018] The beneficial effect of the basic solution is: when the atomized liquid medicine with a temperature lower than the respiratory tract temperature enters the respiratory system, it will make the human body feel uncomfortable and cough. The temperature of the liquid medicine is detected in real time by the temperature sensor, and the heating plate is used to heat the liquid medicine to achieve the temperature control of the atomized liquid medicine, improve the patient's comfort when taking the medicine, and reduce the efficiency of atomized medicine due to uncomfortable behaviors such as coughing.

[0019] Furthermore, the atomization assembly includes an atomizer fixedly connected to the bottom of the box body, the atomizer input port is fixedly connected to a connecting tube for conveying the medicine to be atomized, the atomizer output port is fixedly connected to the inner tube, the connecting tube is connected to a pump at one end away from the atomizer, the output end of the pump is fixedly connected to the connecting tube, the input end of the pump is fixedly connected to a medicine delivery tube, and the other end of the medicine delivery tube is fixedly connected to one side of the medicine storage tank.

[0020] The beneficial effects of the basic solution are: the nebulizer atomizes and then the pump continuously extracts to provide driving force, so that the atomized medicine liquid enters the inner tube for the next step of transportation, and the atomized medicine liquid is pumped to the patient's respiratory system through the nebulizer, reducing the problem of waste caused by overflow of the atomized medicine liquid.

[0021] Furthermore, the medicine storage tank is fixedly connected to an air delivery pipe on one side away from the medicine delivery pipe, the air delivery pipe is connected to the sputum suction assembly at one end away from the medicine delivery pipe, a first electrically-controlled air valve is fixedly connected inside the air delivery pipe, and a second electrically-controlled air valve is fixedly connected to the inner wall of the inner tube located in the drive box.

[0022] The beneficial effects of the basic scheme are: by switching the first electrically controlled air valve and the second electrically controlled air valve, the flow direction restriction in the inner tube and the flow direction restriction in the gap between the inner tube and the outer tube are achieved. On the one hand, the influence of the backflow phenomenon on the efficiency of nebulization and suction is reduced; on the other hand, the absorption of nebulization driven by the negative pressure driving force of suction is reduced, thereby reducing the probability of the nebulized medicine being absorbed before it acts on the patient's respiratory system.

[0023] Furthermore, a button for stopping atomization and starting sputum suction is fixedly connected to the outer top wall of the driving box.

[0024] The beneficial effect of the basic solution is: sending a signal to the intelligent system through a button to control the switching of the first electrically controlled gas valve and the second electrically controlled gas valve, which is convenient for operation and realizes one-touch switching operation steps.

[0025] Furthermore, the sputum suction component includes an elastic contraction tube, in which a plurality of springs are arranged, one end of each spring is fixedly connected to the top wall inside the contraction tube, the other end of each spring is fixedly connected to the bottom wall inside the contraction tube, the bottom of one side of the contraction tube is fixedly connected to the air supply pipe, and the top of the same side of the contraction tube close to the air supply pipe is fixedly connected to the outer tube.

[0026] The beneficial effects of the basic scheme are: due to the elasticity of the contraction tube and the storage pressure property of the spring, energy storage of the pumped atomized liquid medicine is achieved, and the stored energy is released through the atmospheric pressure recovery of the contraction tube and the deformation recovery of the spring by restoring the volume of the contraction tube during the suction process, thereby providing self-driven negative pressure suction and reducing energy waste.

[0027] Furthermore, a connecting rod is fixedly connected to the top wall of the shrinking cylinder, a second one-way air valve is provided in a hole at the top of the shrinking cylinder, and an end of the connecting rod away from the shrinking cylinder passes through the top wall of the driving box and is fixedly connected to a pressing plate, and the connecting rod is slidably matched with the driving box.

[0028] The beneficial effect of the basic scheme is: when the negative pressure for suction is insufficient by releasing the stored energy, the negative pressure for suction can be manually provided by repeatedly compressing and restoring the contraction tube through the pressing plate, reducing the probability of sputum not being completely cleaned due to insufficient negative pressure, thus reflecting its versatility.

[0029] Furthermore, the intelligent system includes a temperature acquisition module, a temperature analysis module, a temperature drive module and a control drive module;

[0032] The temperature driving module is used to control the start-up of the heating plate to heat the liquid medicine;

[0033] The control drive module is used to control the switching of the on / off states of the first electrically-controlled gas valve and the second electrically-controlled gas valve.

DETAILED DESCRIPTION

[0040] The following is further described in detail through specific implementation methods:

[0041] Embodiment 1:

[0042] Basically as attached Figure 1, Figure 2 , Figure 3 and Figure 4 As shown: a multifunctional atomization drug administration and sputum suction cleaning device, comprising an insertion tube 1, the insertion tube 1 is made of elastic rubber material harmless to the human body, one end of the insertion tube 1 is connected to a driving part for atomizing drug liquid and providing a sputum suction driving force, and the end of the insertion tube 1 away from the driving part is welded and connected to an operating head 2 for releasing atomized liquid and sucking sputum; when the patient needs to administer the drug and clean the respiratory tract, the insertion tube 1 is first inserted into the patient's mouth so that the operating head 2 reaches the patient's throat, and the driving part is started to realize the operation of the operating head 2 for atomization drug administration and sputum suction cleaning in the patient's throat, thereby performing the atomization drug administration and sputum suction for the patient in the throat.

[0043] The insertion tube 1 includes an outer tube 101 and an inner tube 102. The outer tube 101 is sleeved outside the inner tube 102 and a gap for sputum to pass through is provided between the outer tube 101 and the inner tube 102. A support block 103 of an annular structure is provided at one end of the outer tube 101 close to the operating head 2. The support block 103 is located at the gap between the outer tube 101 and the inner tube 102. The inner and outer side walls of the support block 103 are respectively welded to the inner tube 102 and the outer tube 101. A plurality of sputum holes for sputum to pass through are opened on the support block 103. Check valves 104 are welded in the sputum holes. A protrusion 105 of a threaded structure is provided on the inner wall of the outer tube 101. After the insertion tube 1 is inserted into the throat, the driving part is started to realize the atomization of the liquid medicine. The atomized liquid medicine overflows from the operating head 2 through the inner tube 102 and directly acts on the patient's respiratory system. On the one hand, it is beneficial to the drug administration efficiency of the patient's respiratory system. On the other hand, it is beneficial to moisten the dry sputum and facilitate the subsequent absorption of the sputum.

[0044] After the nebulization medication is finished, when the patient performs the sputum suction operation, the negative pressure generated by the driving part acts on the gap between the outer tube 101 and the inner tube 102, and the sputum will be sucked into the gap through the operating head 2. The support block 103 is provided to support the gap between the inner tube 102 and the outer tube 101, thereby reducing the probability that the outer tube 101 and the inner tube 102 are closed and the sputum suction operation cannot be performed due to the pressure applied by the patient's throat to the outer tube 101. In addition, since the outer tube 101 is provided with a protrusion 105 with a threaded structure, the friction between the sputum and the wall of the outer tube 101 is increased, and the check valve 104 is used to realize the path of the sputum to flow from the operating head 2 to the gap between the outer tube 101 and the inner tube 102. On the one hand, the sputum can be absorbed and stored in the gap between the outer tube 101 and the inner tube 102. On the other hand, when the inner tube 102 and the outer tube 101 are subsequently taken out, the probability that the sputum is subjected to the centrifugal force caused by inertia and falls back into the patient's respiratory system is reduced.

[0045] In addition, due to the different viscosities of sputum or the differences in the effects of atomization administration, using the gap between the outer tube 101 and the inner tube 102 as a space for storing sputum can reduce the probability that some sputum cannot be absorbed and improve the efficiency of the operating head 2 in absorbing sputum.

By setting the first one-way air valve 203, the probability of sputum entering the inner tube 102 through the mist outlet hole during the sputum absorption stage can be reduced, the secondary contamination of the inner tube 102 by the sputum can be reduced, the steps for cleaning the inner tube 102 can be reduced, and the operation is convenient.

[0048] The suction head 202 is provided with a plurality of suction holes for sputum to pass through; during the suction operation, the sputum will enter the gap between the suction head 202 and the mist outlet head 201 through the suction holes, and then enter the gap between the outer tube 101 and the inner tube 102 under the action of the negative pressure of the driving part, thereby achieving the effect of sputum suction and collection. In addition, the suction holes also serve as a channel for the atomized liquid to overflow the suction head 202, without affecting the overflow of the atomized liquid.

[0049] Embodiment 3:

[0051] A medication port is provided on the top of the driving box 3, and the medication port is detachably connected to a medication cover 302 through a snap-fit ​​structure, a sealing ring 303 is sleeved at the connection between the medication cover 302 and the medication port, a medication tube 401 is fused to the bottom of the medication port, and one end of the medication tube 401 away from the medication port is fused and fixedly connected to a medication storage tank 4; medical staff put the medicine to be atomized into the driving box 3 through the medication port, and then cover the medication cover 302 to achieve an airtight and leak-proof effect between the medication tube 401 and the medication storage tank 4.

[0052] Embodiment 4:

[0053] As attached Figure 3 As shown, the difference from the above embodiment is that a temperature sensor 402 and a heating plate 403 are welded to the inner wall of the medicine storage tank 4; in the atomization drug administration stage, since the temperature of the human respiratory system is close to body temperature, the supercooled drug liquid is directly atomized and administered to the patient's respiratory system, which is likely to cause discomfort to the patient during the drug administration process. The temperature of the drug liquid in the medicine storage tank 4 is detected in real time by the temperature sensor 402, and then the heating plate 403 is controlled by the intelligent system to heat the drug liquid in the medicine storage tank 4, so that the temperature of the drug liquid reaches a temperature that allows the patient to take the drug comfortably, thereby achieving a multifunctional atomization drug administration effect.

[0054] Embodiment 5:

[0055] As attached Figure 3As shown, the difference from the above embodiment is that the atomization assembly includes an atomizer 5 welded to the bottom of the box body, the input port of the atomizer 5 is melted and connected with a connecting pipe 501 for conveying the liquid medicine to be atomized, the output port of the atomizer 5 is melted and connected with the inner tube 102, the end of the connecting tube 501 away from the atomizer 5 is connected with a pump 502, the output end of the pump 502 is melted and connected with the connecting pipe 501, the input end of the pump 502 is connected with a medicine delivery pipe 503, and the other end of the medicine delivery pipe 503 is melted and connected with one side of the medicine storage tank 4; the process of atomizing the liquid medicine is to use the pump 502 to pump the liquid medicine in the medicine storage tank 4 through the drug delivery pipe, the pump 502 and the connecting pipe 501 in sequence into the atomizer 5, the atomization of the atomizer 5 and the continuous extraction of the pump 502 provide a driving force, so that the atomized liquid medicine enters the inner tube 102 for the next step of transportation, so as to achieve the effect of pumping the atomized liquid medicine to the patient's respiratory system through the atomizer 5.

[0056] Embodiment 6:

[0057] As attached Figure 3 As shown, the difference from the above embodiment is that the side of the medicine storage tank 4 away from the medicine delivery tube 503 is melted and connected to the air delivery tube 602, the other end of the air delivery tube 602 is connected to the sputum suction component, the air delivery tube 602 is welded with a first electrically controlled air valve 603, the inner wall of the inner tube 102 located in the driving box 3 is welded with a second electrically controlled air valve 106, and the outer top wall of the driving box 3 is welded with a button 301 for stopping atomization and starting sputum suction; during the process of atomization medication for the patient, the first electrically controlled air valve 603 is in an open state, and the second electrically controlled air valve 106 is in a closed state, so that the flow direction of the plurality of tubes in the driving box 3 is from the sputum suction component to the sputum suction component. The air flows to the air delivery pipe 602, and then from the air delivery pipe 602 to the medicine storage tank 4, and then from the medicine storage tank 4 to the medicine delivery pipe 503, and from the medicine delivery pipe 503 to the nebulizer 5, and finally from the nebulizer 5 to the inner tube 102; at this time, the connection between the outer tube 101 and the sputum suction component is cut off, that is, there is no negative pressure to generate suction force; when the nebulization drug administration is ended, the intelligent system can control the first electrically controlled air valve 603 to be converted into a closed state, and the second electrically controlled air valve 106 to be converted into an open state, so that the connection between the outer tube 101 and the sputum suction component is restored, and the connection between the air delivery pipe 602 and the sputum suction component is cut off, thereby achieving the effect of sputum suction.

[0058] Embodiment 7:

[0059] As attached Figure 3As shown, the difference from the above embodiment is that the sputum suction component includes an elastic shrink tube 6, a plurality of springs 601 are arranged in the shrink tube 6, one end of the spring 601 is welded to the inner top wall of the shrink tube 6, the other end of the spring 601 is welded to the inner bottom wall of the shrink tube 6, the bottom of one side of the shrink tube 6 is melted and connected to the air supply pipe 602, and the top of the same side of the shrink tube 6 close to the air supply pipe 602 is melted and connected to the outer tube 101; in the process of realizing atomization drug administration, since the sealing ring 303 forms a sealed space with the medicine storage tank 4, the volume in the medicine storage tank 4 remains unchanged during the process, and the volume is reduced by extracting the liquid medicine. There will be a difference in atmospheric pressure between the medicine storage tank 4 and the shrink tube 6, so that the gas in the shrink tube 6 is pumped into the medicine storage tank 4. Since the shrink tube 6 is also in a sealed state, the volume of the shrink tube 6 is reduced. At this time, the closed state of the second electrically controlled gas valve 106 makes it impossible for the shrink tube 6 to replenish the gas balance pressure difference. The atmospheric pressure inside and outside the shrink tube 6 will generate pressure on the side wall of the shrink tube 6, causing the shrink tube 6 to be continuously compressed, so that the volume of the shrink tube 6 is reduced. At this time, the spring 601 will be deformed by the pressure to continuously store the downward pressure until the atomization drug delivery process is completed.

[0060] When the atomization drug administration process is finished and the suction operation begins, the second electrically controlled air valve 106 is opened and the first electrically controlled air valve 603 is closed. At this time, the connection state between the outer tube 101 and the contraction tube 6 is restored. At the same time, the spring 601 releases the stored pressure to restore the volume of the contraction tube 6, so that the gas in the gap between the outer tube 101 and the inner tube 102 and the gap between the suction head 202 and the mist outlet head 201 will escape into the contraction tube 6. At this time, the negative pressure generated by the contraction tube 6 will produce a suction effect, acting on the suction head 202 to produce the effect of suction; the effect of self-driven suction negative pressure is achieved, which saves resources and facilitates operation.

[0061] A connecting rod 604 is welded to the top wall of the contraction tube 6, and a second one-way air valve 606 is provided at the top opening of the contraction tube 6. A pressing plate 605 is welded to the top wall of the driving box 3 at one end of the connecting rod 604 away from the contraction tube 6, and the connecting rod 604 slides with the driving box 3. Taking into account that some patients have different sputum consistencies and accumulation conditions, when the negative pressure generated by the deformation stored in the contraction tube 6 cannot completely absorb the sputum, since the gas flow direction of the second one-way air valve 6 is from the outside of the contraction tube 6 to the inside of the contraction tube 6, at this time, the medical staff compresses the contraction tube 6 by pressing the pressing plate 605 to reduce the volume of the contraction tube 6, and pulls up the pressing plate 605 to restore the volume of the contraction tube 6. Repeated operations continuously generate negative pressure for suction to absorb the sputum, which can reduce the probability of incomplete absorption of the sputum.

[0062] Embodiment 8:

[0063] The difference from the above embodiment is that the intelligent system includes a temperature acquisition module, a temperature analysis module, a temperature drive module and a control drive module.

[0064] The temperature acquisition module collects the temperature signal of the liquid in the liquid storage tank through the temperature sensor 402, and converts the temperature signal into temperature data and transmits it to the temperature analysis module.

[0065] The temperature analysis module is used to receive temperature data and compare the temperature data with the human body temperature of 37°C. When the temperature data of the medicine solution is greater than 37°C, a signal to stop heating is sent to the temperature driving module. When the temperature data is less than 37°C, a signal to increase the temperature is sent to the temperature driving module.

[0066] The temperature driving module is used to receive the signal of needing to increase the temperature and stopping the temperature increase, and after receiving the signal, drive and control the heating plate 403 to start and stop.
