Description

Technical Field

[0001] The present invention relates to the field of medical devices, and more specifically, to a ventilator and a ventilator system. Background Art

[0002] A ventilator is an important device in modern medicine for assisting or controlling a patient's breathing, and is widely used in multiple medical scenarios such as intensive care, first aid, and anesthesia.

[0003] Some patients (such as those with weak constitutions, fever, or nervousness and anxiety) are prone to sweating themselves. When using a ventilator, the problem of local sweating is more prominent. Since the mask needs to fit tightly against the face to ensure the ventilation effect, the air permeability of the contact area is poor, and the sweat is difficult to evaporate. This will not only reduce the friction between the mask and the skin, resulting in mask displacement or air leakage and affecting the treatment effect, but also provide a humid environment for bacterial growth, increasing the risk of skin infection. In addition, the sweat stimulation may cause skin redness, itching, and even damage, reducing the patient's comfort and compliance.

[0004] Therefore, a ventilator and a ventilator system are proposed. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a ventilator and a ventilator system, which can improve the comfort of the patient when wearing the mask.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

[0007] A ventilator includes a main unit, a mask, and an air duct; An exhaust port is provided on the main unit, and the air duct is used to connect the exhaust port and the mask; A first sealing strip is provided on the side wall of the mask, and an elastic strap is provided on the mask, and the elastic strap is used to fix the mask; A diversion groove is formed on the side wall of the mask, a mounting plate is slidably installed in the diversion groove, and an elastic film is jointly installed between the side wall of the diversion groove and the mounting plate; a second sealing strip is fixedly installed on the mounting plate, and a driving mechanism for driving the mounting plate to move is provided on the mask; A cavity is formed on the second sealing strip, air holes are uniformly formed on the side wall of the cavity, and a pressure relief hole is formed on the side wall of the cavity.

[0008] Further, the driving mechanism includes an electromagnet fixedly installed on the side wall of the diversion groove far from the second sealing strip, the mounting plate is made of a magnetic material, and the mounting plate is repelled when the electromagnet is energized.

[0009] Further, an installation cavity is formed on the side wall of the first sealing strip, a sponge is provided in the installation cavity, a through hole communicating with the outside is formed on the bottom wall of the installation cavity, and the sponge fills the through hole.

[0010] Further, a catheter is inserted into the top wall of the installation cavity, and the catheter communicates with the outside.

[0011] Further, a jack is provided on the mask, a slider is slidably installed in the jack, a spring is installed between the slider and the bottom wall of the jack, and a connecting rope is jointly installed between the slider and the elastic strap.

[0012] Further, the slider is made of a magnetic material, and the slider repels the electromagnet.

[0013] Further, both the first sealing strip and the second sealing strip are made of silica gel.

[0014] Further, a pressure detection module is provided inside the mask, and the pressure detection module is used to detect the air pressure inside the mask; A controller is provided on the main unit, and the controller is used to control the air exhaust volume of the air pump.

[0015] A ventilator system includes a humidity detection module, a control module, and a timer; The humidity detection module is used to detect the sweat content on the skin surface and send the detection data to the control module; The control module judges the received data and then sends the judgment result to the timer; The timer is used to control the start and stop of the electromagnet.

[0016] Further, the humidity detection module adopts a humidity sensor. First, the humidity sensor and the timer are initialized; then the data of the humidity sensor is read cyclically, and the read result is sent to the control module.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) Through the mutual cooperation of the first sealing strip, the second sealing strip and the driving mechanism, when sweat is generated at the part where the first sealing strip contacts the skin, the first sealing strip is separated from the skin contact, and at the same time, the gas inside the mask is discharged through the pressure relief hole. At this time, the air flow rate on the surface of the sweat is increased, the evaporation rate of the sweat is accelerated, the comfort is improved, and at the same time, when the patient wears the mask to sleep, the friction between the mask and the skin can be ensured, preventing the mask from shifting; when the first sealing strip and the second sealing strip alternately contact the skin, the skin can be massaged, which plays a role in improving the comfort compared with the continuous pressure on a certain part of the skin.

[0018] (2) Through the mutual cooperation of the installation cavity, the sponge and the through holes, when the first sealing strip contacts the skin, the sponge also contacts the skin. At this time, the sponge can absorb sweat, thereby improving the comfort during use, and the sponge contacts the skin through the through holes, which can ensure the contact area between the first sealing strip and the skin, prevent the skin from being subjected to excessive pressure, and play a role in improving the comfort.

[0019] (3) In this solution, by setting the air duct, part of the gas in the mask will pass through the through holes into the installation cavity, pass through the sponge, and then be discharged to the outside through the duct; during the process of the air flow passing through the sponge, the air flow rate around the sponge is accelerated, that is, the evaporation rate of the sweat in the sponge is increased, which plays a role in automatically drying the sponge. When the sponge comes into contact with the skin again, it plays a role in ensuring that the sponge can absorb sweat.

[0020] (4) In this solution, through the mutual cooperation of the electromagnet, the slider, and the connecting rope, when the electromagnet is energized, a magnetic field that repels the slider is generated around the electromagnet. Therefore, the slider is subjected to a repulsive force. At this time, the repulsive force is greater than the spring elastic force. Therefore, the slider moves in a direction away from the electromagnet. At this time, the originally relaxed part is gradually subjected to pressure, and the overall deformation degree of the elastic band decreases. Therefore, the pressure of the elastic band on the mask decreases, ensuring that when the electromagnet receives a reaction force, it can drive the mask to disengage from the skin contact.

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment 1: Please refer to Figures 1 to 7 , a ventilator, comprising a main unit 1, a face mask 2 and an air duct 3; An exhaust port is provided on the main unit 1. The main unit 1 is used to generate gas. The air duct 3 is used to connect the exhaust port and the face mask 2 and convey breathing gas. The face mask 2 is used to provide breathing gas to the patient; Among them, the main unit 1 includes an air pump and a power supply module. The power supply module supplies power to the air pump. The output end of the air pump is communicated with the exhaust port of the main unit 1, which is prior art and will not be elaborated herein; Elastic first sealing strips 4 are fixedly installed on the side walls on both the inner and outer sides of the face mask 2, and an elastic strap 24 is provided on the face mask 2. The elastic strap 24 is used to fix the face mask 2. First, the elastic strap 24 made of elastic material is installed on the side wall of the face mask 2. When the patient needs to wear the face mask 2, the air pump is started, and the gas discharged by the air pump is conveyed to the face mask 2 through the air duct 3. Then the face mask 2 is placed at the mouth and nose, and the elastic strap 24 is put on the head. At this time, the face mask 2 is fixed at the mouth and nose, and the first sealing strip 4 is in a squeezed state and deforms, so as to be able to fill the gap between the face mask 2 and the skin surface, thereby improving the sealing performance of the face mask 2 and playing a role in ensuring that the face mask 2 can supply gas to the patient and assist the patient in breathing; and the setting of two first sealing strips 4 increases the force-bearing area of the skin, reduces the pressure on the skin, and improves comfort; A diversion groove 5 is formed on the side wall of the face mask 2. A mounting plate 6 is slidably installed in the diversion groove 5. An elastic membrane 7 is jointly installed between the side wall of the diversion groove 5 and the mounting plate 6 to prevent the mounting plate 6 from falling out of the diversion groove 5 by setting the elastic membrane 7; a second sealing strip 8 is fixedly installed on the mounting plate 6, and a driving mechanism for driving the mounting plate 6 to move is provided on the face mask 2; When the driving mechanism pushes the mounting plate 6 to slide along the guide groove 5, the second sealing strip 8 is pushed out of the guide groove 5 by the mounting plate 6 until the second sealing strip 8 contacts the skin, and then the second sealing strip 8 continues to be pushed until the second sealing strip 8 can no longer move due to the resistance of the skin. At this time, the driving mechanism continues to push the mounting plate 6, and the driving mechanism's thrust on the mounting plate 6 is greater than the elastic force of the elastic strap 24, so the mask 2 gradually moves away from the skin and drives the first sealing strip 4 out of contact with the skin. At this time, the sweat sandwiched between the first sealing strip 4 and the skin can evaporate normally. When the sweat on the skin surface evaporates, the user's comfort can be improved, and when the first sealing strip 4 contacts the skin again, the friction of the contact part is guaranteed, which reduces the probability of displacement of the mask 2, prevents gas leakage during use, and improves safety.

[0025] A cavity 9 is formed on the second sealing strip 8. An air hole 10 is formed on the side wall of the cavity 9 close to the outer wall of the mask 2, and the bottom of the air hole 10 points to the skin. A pressure relief hole 11 is formed on the side wall of the cavity 9 away from the outer side of the mask 2. The pressure relief hole 11 is connected to the guide groove 5. When the second sealing strip 8 does not extend from the guide groove 5, one end of the pressure relief hole 11 is in contact with the side wall of the guide groove 5, and the first sealing strip 4 is in close contact with the skin, thereby preventing gas leakage in the mask 2.

[0026] When the first sealing strip 4 breaks contact with the skin and the second sealing strip 8 extends from the guide groove 5, part of the gas in the mask 2 is discharged into the cavity 9 through the pressure relief hole 11, and then discharged through the air holes 10 evenly distributed on the side wall of the cavity 9. The gas discharged from the air hole 10 impacts the sweat remaining on the skin surface, thereby accelerating the evaporation rate of the sweat, which improves the comfort level; and in the process of exhausting the pressure relief hole 11, it can drive the air flow on the skin surface below the first sealing strip 4 inside the mask 2, thereby accelerating the evaporation rate of sweat on the skin surface in this area.

[0027] When the first sealing strip 4 and the second sealing strip 8 are in contact with the skin alternately, the skin can be massaged, which improves the comfort level compared to a certain part of the skin being continuously pressurized.

[0028] Because the patients are physically weak, even in winter, patients with Qi deficiency may sweat after activities or while sleeping, and patients with spleen deficiency may experience symptoms such as indigestion, acid reflux, belching, etc., accompanied by sweating.

[0029] However, in winter, the environmental temperature is relatively low. Therefore, the mask 2 is in a low-temperature environment. When wearing the mask 2 to assist breathing, the hot air exhaled will liquefy into small water droplets when contacting the inner wall of the mask 2. Therefore, during the exhaust process through the pressure relief hole 11, it can drive the air flow around the small water droplets, thereby increasing the evaporation rate of the small water droplets and preventing the small water droplets from being inhaled into the patient's nasal cavity.

[0030] Among them, fixing the mask 2 through the elastic strap 24 is an existing technology and will not be elaborated here.

[0031] As Figure 5 shown, the driving mechanism includes an electromagnet 12 fixedly installed on the side wall of the diversion groove 5 away from the second sealing strip 8. The mounting plate 6 is made of a magnetic material, and the mounting plate 6 is repelled when the electromagnet 12 is energized.

[0032] When the skin sweats at the contact part with the first sealing strip 4, the electromagnet 12 is activated. At this time, a magnetic field that repels the mounting plate 6 is generated around the electromagnet 12. Under the action of the magnetic field repulsion force, the mounting plate 6 will move away from the electromagnet 12, thus playing a role in driving the movement of the mounting plate 6. At the same time, the elastic membrane 7 deforms.

[0033] When the electromagnet 12 is powered off, the repulsion force on the mounting plate 6 disappears. At this time, the elastic membrane 7 resumes its original shape and drives the mounting plate 6 to reset, playing a role in preparing for the next operation.

[0034] As Figure 5 shown, an installation cavity is provided on the side wall of the first sealing strip 4 in contact with the skin. A sponge 13 is provided in the installation cavity. A through hole 14 communicating with the outside is provided on the bottom wall of the installation cavity, and the sponge 13 fills the through hole 14. Therefore, when the first sealing strip 4 contacts the skin, the sponge 13 also contacts the skin. At this time, the sponge 13 can absorb sweat, thereby improving the comfort during use. Moreover, the sponge 13 contacts the skin through the through hole 14, which can ensure the contact area between the first sealing strip 4 and the skin and prevent the skin from being under excessive pressure, playing a role in improving comfort.

[0035] As Figure 5 shown, a conduit 15 is inserted into the top wall of the installation cavity. One end of the conduit 15 away from the installation cavity communicates with the outside.

[0036] Since the air duct 3 supplies gas to the inside of the mask 2, the air pressure inside the mask 2 is higher than the outside air pressure. When the first sealing strip 4 is separated from the skin, part of the gas inside the mask 2 will pass through the through hole 14 into the installation cavity, pass through the sponge 13, and then be discharged to the outside through the conduit 15; during the process of the air flow passing through the sponge 13, the air flow rate around the sponge 13 is increased, that is, the evaporation rate of the sweat in the sponge 13 is increased, playing a role in automatically drying the sponge 13.

[0037] AsFigure 5 As shown, the mask 2 is provided with an insertion hole, a slider 16 is slidably installed in the insertion hole, a spring 17 is installed between the slider 16 and the bottom wall of the insertion hole, and a connecting rope 18 is installed between the slider 16 and the elastic band 24.

[0038] like Figure 5 As shown, the slider 16 is made of magnetic material, and the slider 16 and the electromagnet 12 repel each other.

[0039] When the electromagnet 12 is not energized, under the action of the spring 17, the slider 16 is located at the end of the jack near the electromagnet 12. At this time, the connecting rope 18 pulls the elastic band 24, so the part of the elastic band 24 located between the connecting rope 18 and the mask 2 is in a relaxed state.

[0040] When the electromagnet 12 is energized, a magnetic field is generated around the electromagnet 12 that repels the slider 16. As a result, the slider 16 is subjected to a repulsive force. At this time, the repulsive force is greater than the elastic force of the spring 17. Therefore, the slider 16 moves in a direction away from the electromagnet 12. At this time, the part that was originally in a relaxed state is gradually subjected to pressure, and the overall deformation of the elastic strap 24 is reduced. Therefore, the pressure of the elastic strap 24 on the mask 2 is reduced, ensuring that the electromagnet 12 can drive the mask 2 out of contact with the skin when it is subjected to a reaction force.

[0041] like Figure 4 As shown, the first sealing strip 4 and the second sealing strip 8 are both made of silicone.

[0042] The silicone material is soft to the touch, reducing the sense of pressure on the skin. The elasticity of silicone can disperse pressure, avoid excessive local pressure, and reduce the risk of skin pressure sores.

[0043] like Figure 1 、 Figure 4 As shown, a pressure detection module 19 is provided in the mask 2, and the pressure detection module 19 is used to detect the air pressure in the mask 2 to ensure that the air pump can provide a sufficient amount of gas to the mask 2; The main engine 1 is provided with a controller 20 , which is used to control the exhaust volume of the main engine 1 .

[0044] The pressure detection module 19 uses a pressure sensor to detect the air pressure in the mask 2 in real time, converts the air pressure signal into an electrical signal, and sends it to the controller 20.

[0045] The controller 20 receives the signal from the pressure sensor, compares it with the set air pressure value, and outputs a control signal to control the operation of the air pump.

[0046] Therefore, during the process of exhausting air from the face mask 2 through the pressure relief hole 11 and the conduit 15, when the pressure detection module 19 detects that the air pressure inside the face mask 2 is less than the preset value, the pressure detection module 19 sends a signal to the controller 20, and the controller 20 controls the air pump to increase its power. At this time, it can ensure that the air pressure inside the face mask 2 is constant, ensuring that the inside of the face mask 2 can be in a constant pressure state, playing a role in improving safety.

[0047] A ventilator system includes a humidity detection module 21, a control module 22, and a timer 23; The humidity detection module 21 is embedded in the side wall of the first sealing strip 4 on the side in contact with the skin, and the humidity detection module 21 is used to detect the sweat content on the skin surface and send the detection data to the control module 22; The control module 22 is arranged on the main unit 1, judges the received data, and then sends the judgment result to the timer 23; The timer 23 is arranged on the main unit 1, and the timer 23 is used to control the start and stop of the electromagnet 12.

[0048] As Figure 5 shown, the humidity detection module 21 uses a humidity sensor. First, the humidity sensor and the timer 23 are initialized; then the data of the humidity sensor is read cyclically, and the reading result is sent to the control module 22; and the humidity detection module 21 is connected to the power supply system of the main unit 1 and the timer 23 through a wire, thereby ensuring that the humidity detection module 21 can work normally. Moreover, the wire penetrates through the air duct 3. After the wire penetrates through the air duct 3, the air duct 3 serves as a physical barrier, which can effectively prevent the insulation layer of the wire from being worn and extend the service life of the wire.

[0049]

[0050] When X≥0, the control module 22 sends the value of X to the timer 23. At this time, the timer 23 controls the electromagnet 12 to be energized and remains energized for 10 seconds; When X<0, the control module 22 sends the value of X to the timer 23. At this time, the timer 23 controls the electromagnet 12 to be de-energized; Wherein, C is the amount of sweat on the skin surface detected by the humidity sensor; C0 is a preset value. When the amount of sweat on the skin surface is greater than or equal to C0, the skin has discomfort.

[0051] As mentioned above, it is only a preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
