Technical Field

[0001] The present invention relates to the field of cold therapy health, and in particular to a respiratory protection device and a cold therapy device for cold therapy. Background Art

[0002] Cryotherapy is currently a popular method of treating diseases. The freezing chamber where the user undergoes cryotherapy is a low-temperature environment of about -140℃, which is much lower than the human body temperature. The low-temperature environment quickly contacts the whole or part of the human body, causing the whole or part of the human body to cool down rapidly in a short period of time, thereby promoting circulation and metabolism, alleviating sports injuries, enhancing the body's immunity, improving sleep, regulating stress and emotions, and even treating diseases.

[0003] In the process of implementing the present invention, the applicant discovered that there are at least the following problems in the prior art:

[0004] Because the temperature inside the freezer is very low, if users breathe directly into the freezer, there is a risk of damage to the respiratory system caused by the inhaled ultra-low temperature gas. Summary of the invention

[0005] The embodiments of the present invention provide a respiratory protection device and a cryotherapy device for cryotherapy, which can solve the technical problem in the prior art that the temperature in the freezing chamber is very low and the user breathes directly, and the inhaled ultra-low temperature gas may cause respiratory system damage.

[0019] The following will be combined with the drawings in the embodiments of 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.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, in combination with an embodiment of the present invention, a respiratory protection device for cold therapy is provided, comprising a breathing gas supply device 1, a mask 27 and a gas delivery pipeline 26, wherein the mask 27 is arranged in a freezing chamber 9, the breathing gas supply device 1 is arranged in a control room 8, and the control room 8 is arranged adjacent to the freezing chamber 9;

[0021] The first end of the gas delivery pipeline 26 can be connected to the breathing gas supply device 1, and the second end of the gas delivery pipeline 26 can be connected to the mask 27. The breathing gas supply device 1 is used to provide breathing gas to the user 23 wearing the mask 27 through the gas delivery pipeline 26;

[0022] The breathing gas supply device 1 comprises a temperature controller 19 , which is used to adjust the temperature of the breathing gas in the breathing gas supply device 1 to within a preset range and to deliver the breathing gas to the first end of the gas delivery pipeline 26 .

[0023] The freezing chamber 9 uses a low-temperature medium such as liquid nitrogen for refrigeration. After the user 23 enters, he wears a mask 27. The mask 27 can obtain breathing gas (containing a large amount of oxygen, which can be high-concentration oxygen: the volume ratio is not less than 90%) from the breathing gas supply device 1 for the user 23 to breathe, and the temperature of the breathing gas is within a preset range, that is, it is not at a low temperature (for example, below -30°C), so that the user 23 does not breathe the low-temperature gas in the freezing chamber 9, thereby protecting the respiratory system of the user 23 and avoiding frostbite of the user's 23 respiratory tract caused by the low-temperature gas.

[0024] In addition, because many cold storage chambers 9 currently use liquid nitrogen for refrigeration in low-temperature environments, users are prone to poisoning caused by excessively high nitrogen concentrations in relatively closed cold storage chambers. That is, when the nitrogen content in the air is greater than 84% and the oxygen content is less than 16%, simple hypoxia and asphyxiation may occur. The breathing gas supply device 1 provides the user 23 with breathing gas (containing a large amount of oxygen, which may be high-concentration oxygen: the volume ratio is not less than 90%), thereby avoiding the occurrence of hypoxia and asphyxiation poisoning caused by inhaling too much nitrogen due to too low oxygen concentration.

[0025] In addition, when the human body is exposed to low temperatures, the blood vessels on the surface of the skin will contract, causing blood to flow to the core parts and organs of the body. At the same time, the heart rate will increase and the amount of blood ejected by the heart will also increase in the early stage of low temperature. When combined with breathing high-concentration oxygen (volume ratio of not less than 90%), it will have deeper benefits to the health of the body beyond the effects of ordinary low temperature therapy, including strengthening the nutrient supply to the internal organs, promoting the body's oxidation and detoxification, etc.

[0026] Preferably, the breathing gas supply device 1 comprises a power device 22, an air pump 16 and an air source device, wherein the power device 22 is connected to the air pump 16 to provide power for the air pump 16, and the air pump 16 is used to pump external air into the air source device as an air source after the power device 22 provides power;

[0027] The gas source device includes a molecular sieve 18 , and the molecular sieve 18 is used to absorb nitrogen in the air pumped in by the air pump 16 .

[0028] The molecular sieve 18 is used to adsorb nitrogen molecules in the air and allow oxygen molecules to pass through, thereby increasing the volume percentage of oxygen, so that the volume percentage of oxygen is approximately not less than 90%.

[0029] Preferably, the air source device further comprises a filter 17, which is connected to the molecular sieve 18 and is located upstream of the molecular sieve 18 in the flow direction of the air source, and the filter 17 is used to filter out impurities in the pumped air, and the air with impurities filtered out can enter the molecular sieve 18. The filter 17 is used to filter out impurities, dust, etc. in the air source to improve cleanliness.

[0030] Preferably, the breathing gas supply device 1 further comprises a breathing gas outlet 20 and a concentration sensor. In the flow direction of the gas source, the temperature controller 19 is connected to the molecular sieve 18 and is located downstream of the molecular sieve 18. The breathing gas outlet 20 is connected to the temperature controller 19 and is located downstream of the temperature controller 19. The concentration sensor is provided at the breathing gas outlet 20 and is used to detect the flow rate of the breathing gas output from the temperature controller 19 and the concentration of oxygen in the breathing gas.

[0031] The first end of the gas delivery pipeline 26 is connected to the breathing gas outlet 20;

[0032] The respiratory protection device for cold therapy also includes a central controller, which includes a concentration controller. The concentration controller is electrically connected to the concentration sensor. The concentration controller is used to regulate the flow rate of the breathing gas according to the flow rate of the breathing gas and the concentration of oxygen in the breathing gas detected by the concentration sensor, so that the volume proportion of oxygen provided to the user 23 is approximately not less than 90%.

[0033] When the temperature of the breathing gas detected by the temperature sensor of the temperature controller 19 is lower than the lower limit of the temperature (e.g. 10°C), the electric heating device of the temperature controller 19 is turned on through the control switch of the temperature controller 19 to heat the breathing gas. When the temperature of the breathing gas approaches or reaches the lower limit, the electric heating device is turned off through the control switch and the heating stops. When the temperature exceeds the upper limit (e.g. 40°C), an alarm is sounded and the relevant operator is notified.

[0034] When the breathing gas supply device 1 is working, the power device 22, such as a power source, drives the air pump 16 to pump the outside air into the breathing gas supply device 1. The outside air passes through the filter 17, the molecular sieve 18, and the temperature controller 19 in sequence, and enters the gas delivery pipeline 2 along the breathing gas flow direction 3 through the breathing gas outlet 20.

[0035] Other internal structures of the breathing gas supply device 1, or the connection relationship between the internal structures that are not shown, can all adopt the existing technology, and the present invention does not improve and protect them.

[0036] Preferably, the mask 27 includes a face fitting surface and a face non-fitting surface, and the face fitting surface and the face non-fitting surface are arranged opposite to each other;

[0037] The mask 27 has a one-way air outlet 25, and the air outlet direction of the one-way air outlet 25 is directed from the face-fitting surface to the face-non-fitting surface;

[0038] The one-way air outlet 25 is disposed on the left side and / or right side of the mask 27 , and the left side and the right side of the mask 27 correspond to the left side and the right side of the face of the user 23 , respectively.

[0039] When the user 23 uses the mask 27, the user 23 connects and fixes the gas delivery pipeline 26 to the breathing gas outlet 20, adjusts the mask fixing belt 24 and wears the mask 27 to cover the mouth and nose.

[0040] When the breathing mask is working, the breathing gas outlet 20 can provide breathing gas to the user 23, allowing the user to breathe smoothly, and the gas exhaled by the user 23 is discharged through the one-way air outlets 25 on both sides of the mask 27.

[0041] After use, the user 23 disconnects the gas delivery pipeline 26 from the breathing gas outlet 20 and takes off the mask 27. The one-way air outlet 25 is arranged on the left and right sides of the mask 27, and the gas exhaled by the user 23 is discharged from both sides of the mask, staggered in front of the nostrils of the user 23, so that the inhalation and exhalation take different routes; in addition, if the user 23 wears glasses, the situation of "glasses fogging" will not occur.

[0042] Preferably, the respiratory protection device for cold therapy also includes a flexible air storage bag 31 for storing breathing gas, the flexible air storage bag 31 is arranged outside the non-fitting surface of the mask 27, the second end of the gas delivery pipeline 26 is connected to the air storage bag air inlet of the flexible air storage bag 31, the air storage bag air outlet 29 of the flexible air storage bag 31 is connected to the mask air inlet of the mask 27, and the mask air inlet is located at the nostrils of the user 23 and within the range around the nostrils.

[0043] After the breathing gas from the breathing gas supply device 1 enters the flexible air storage bag 31 along the breathing gas air flow direction 3 in the gas delivery pipeline 26, because the flexible air storage bag 31 is a bag, its diameter is much larger than that of the gas delivery pipeline 26. Therefore, the flexible air storage bag 31 will have a buffering and deceleration effect on the breathing gas entering therein, and the flow rate of the breathing gas when it is connected to the mask air inlet of the mask 27 through the air storage bag air outlet 29 will be reduced. The breathing gas is relatively soft, so it can reduce the airflow of the breathing gas impacting the respiratory system of the user 23 and causing the user 23 to feel uncomfortable with the respiratory system.

[0044] Preferably, the flexible air storage bag 31 also includes an air storage bag outlet valve 30, which is arranged on the air storage bag outlet port 29 and is used to control the breathing gas to enter the mask air inlet of the mask 27 from the air storage bag outlet port 29 in one direction, and from the mask air inlet in one direction to the mask 27, that is, the breathing gas flows in one direction and can only enter the mask 27 from the side of the flexible air storage bag 31, and cannot flow back from the mask 27 to the flexible air storage bag 31, thereby further controlling the flow rate and flexibility of the breathing gas.

[0045] Preferably, the air storage bag outlet valve 30 is a one-way valve, which is used to form a passage when the user 23 inhales, and the valve sheet of the one-way valve opens to form a passage, and the breathing gas enters the mask air inlet from the flexible air storage bag 31 through the air storage bag outlet 29. When the user 23 finishes inhaling, the valve sheet of the one-way valve closes and the passage is closed, which further controls the flow rate and softness of the breathing gas and prevents the exhaled gas after breathing from flowing back into the flexible air storage bag 31.

[0046] Preferably, the gas delivery pipeline 26 is a flexible pipeline made of flexible material. The gas delivery pipeline 26 is fixed above the freezing chamber 9, and a certain movable length is reserved for the gas delivery pipeline 26 so that the user 23 can move in the freezing chamber 9 after wearing the mask 27, without affecting the normal activity needs of the user 23.

[0047] With respect to the respiratory protection device for cold therapy of the embodiment of the present invention, the unmentioned structures and the connection relationships between the unmentioned structures are all prior art, and the present invention does not provide any improvement or protection.

[0048] In combination with an embodiment of the present invention, a cold therapy device is also provided, comprising a control room 8, a freezing chamber 9 and any one of the aforementioned respiratory protection devices for cold therapy, wherein the control room 8 and the freezing chamber 9 are arranged adjacent to each other, the control room 8 can be connected to the freezing chamber 9, the control room 8 can cool the freezing chamber 9, and the freezing chamber 9 is used to perform cold therapy on the user 23.

[0049] When the cryotherapy device is working, the control room 8 starts working, the breathing gas supply device 1 provides breathing gas to the freezing chamber 9, and the breathing gas enters the freezing chamber 9 along the breathing gas airflow direction 3. At the same time, the refrigeration control unit 4 forms a cold air flow 6 through the cold air inlet 5 to provide a low-temperature nitrogen gas flow to the freezing chamber 9. After the cryotherapy device operates normally and the temperature in the freezing chamber 9 reaches the standard, the temperature range is: -80℃~-160℃, and the user 23 enters the freezing chamber 9 through the freezing chamber door 10. After the treatment is over, the user 23 leaves through the freezing chamber door 10. Except for the cold air inlet 5 and the freezing chamber door 10, the freezing chamber 9 is in a sealed state.

[0050] When the refrigeration control unit 4 is working, the liquid nitrogen pump 310 draws liquid nitrogen from the liquid nitrogen tank 28 (the liquid nitrogen level 290 can be seen) through the liquid nitrogen guiding pipe 300, and reaches the upper nozzle 341, the middle nozzle 342, and the lower nozzle 343 from the liquid nitrogen outlet pipe 32 via the liquid separation module 33. The upper nozzle 341, the middle nozzle 342, and the lower nozzle 343 spray the liquid nitrogen. After being sprayed out, the liquid nitrogen vaporizes and refrigerates, and enters the freezing chamber 9 from the cold air inlet channel 35.
