Description

TECHNICAL FIELD

[0001] The utility model relates to medical equipment technical field especially, and it is safe, convenient oxygen inhalation device. BACKGROUND

[0002] The oxygen produced by the oxygen generator does not contain water vapor, in order to solve the problem of damage to respiratory mucosa caused by too dry oxygen, the prior art uses a humidification cup to humidify the oxygen (see Figure 1 ), the oxygen inlet pipe is inserted into water, and then the oxygen is discharged from the water in the form of bubbles, and then discharged from the gas outlet at the top of the humidification cup for the patient to breathe. After the oxygen passes through the water, the water content of the oxygen increases to achieve the effect of humidification. The humidified oxygen is supplied to the patient through the mask oxygen inhalation tube or the nasal oxygen inhalation catheter connected directly to the gas outlet, which can humidify the patient's airway and prevent the respiratory mucosa from drying out and causing bleeding.

[0003] During use, the oxygen discharged from the water will make "gurgling" noise, affecting the patient's rest. After the oxygen inhalation is completed, as the temperature in the oxygen pipe decreases, negative pressure will gradually form in the oxygen pipe, and water will flow into the oxygen generator through the inlet pipe, causing the molecular sieve to fail. In addition, if the inlet pipe and the outlet pipe are installed in reverse, the water in the humidification cup will flow into the patient's nasal cavity through the outlet pipe, causing the patient to be choked by water, even lung water, causing dry drowning death medical accident. When the mask oxygen inhalation patient needs to switch to nasal catheter oxygen inhalation for drinking or eating, the mask oxygen inhalation tube needs to be removed and replaced with a nasal catheter, which is very inconvenient. SUMMARY

[0004] In view of the above technical problems existing in the prior art, the present application provides a safe and convenient oxygen inhalation device.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] A safe and convenient oxygen inhalation device comprises a humidification cup assembly and an oxygen inhalation tube assembly.

[0007] The humidification cup assembly comprises an air inlet cavity located below, an air inlet is arranged on the air inlet cavity, and a water storage cavity is detachably and fixedly connected to the upper surface of the air inlet cavity. A water-separation and air-permeable membrane is arranged at the fixed connection between the air inlet cavity and the water storage cavity and separates the air inlet cavity and the water storage cavity. An air outlet and a water inlet are arranged above the water storage cavity.

[0008] The oxygen inhalation tube assembly comprises an oxygen delivery tube, and the lower end of the oxygen delivery tube is sleeved on the air outlet of the humidification cup assembly.

[0009] Preferably, the oxygen inhalation tube assembly further comprises a tee connected to the upper end of the oxygen delivery tube, a reversing switch is arranged in the tee, and the left and right outlets at the upper end of the tee are respectively connected with a nasal catheter and a mask oxygen inhalation tube.

[0010] Preferably, the water-resisting and air-permeable film is made of polytetrafluoroethylene or TPU film or PU film.

[0011] Preferably, a safety pressure relief valve is arranged above the water storage cavity.

[0015] The utility model has the beneficial effects that:

[0016] 1. The water-resisting and air-permeable film separates the air inlet cavity and the water storage cavity, and can prevent water from flowing into the patient's nasal cavity through the oxygen pipe in the case of reverse installation of the air inlet pipe and the air outlet pipe, thereby avoiding medical accidents.

[0017] 2. After oxygen inhalation, the temperature in the oxygen inlet pipe decreases to form a negative pressure, and the water-resisting and air-permeable film has a certain strength and elastic deformation capacity, thereby preventing water from flowing into the oxygen generator through the air inlet pipe and damaging the molecular sieve.

[0029] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation

[0030] The present invention will now be further described with reference to the accompanying drawings.

[0031] Example 1:

[0032] like Figure 2 As shown, a safe and convenient oxygen inhalation device according to an embodiment of the present invention includes a humidification cup assembly 1 and an oxygen inhalation tube assembly 2.

[0033] like Figure 2 , Figure 4 , Figure 5 As shown, the humidification cup assembly 1 includes an air inlet chamber 11 located at the bottom, an air inlet 12 is provided on the side of the air inlet chamber 11, and a water storage chamber 14 is fixedly connected to the air inlet chamber 11 via a flange 17. A water-proof and breathable membrane 13 is provided at the flange connection between the air inlet chamber 11 and the water storage chamber 14. An air outlet 15 and a water inlet 16 are provided above the water storage chamber 14.

[0034] The connection between the air intake chamber 11 and the water storage chamber 14 can also be a threaded connection or a socket-type detachable fixed connection.

[0035] The waterproof and breathable membrane 13 can be made of polytetrafluoroethylene, TPU film, or PU film.

[0036] The working principle of the water-proof and air-permeable film 13 is as follows: the water-proof and air-permeable film 13 is a kind of micro-porous new material, the micro-porous channels are connected into a net-like three-dimensional structure in the film, and are uniformly and densely distributed, the minimum pore diameter can be 0.1 microns, which is much larger than the diameter 0.000346 microns of oxygen, so that the oxygen can pass through smoothly; due to the surface tension of water droplets (mutual "pulling and counteracting" between water molecules), the water droplets form spheres with a diameter of 500 microns to 2000 microns, which is much larger than the pore diameter of the water-proof and air-permeable film, so that the water molecules cannot penetrate to the other side of the water-proof and air-permeable film smoothly, and the penetration of water is prevented, so that the air-permeable film has the function of preventing water. In addition, under the pressure of the oxygen machine, the air permeation of the water-proof and air-permeable film 13 can exceed 300 L / m² / min, which meets the demand of the maximum oxygen consumption of the patient.

[0037] In use, a proper amount of pure water is added to the water storage cavity 14 through the water inlet 16, and due to the water-proof effect of the water-proof and air-permeable film 13, the water cannot flow into the air inlet cavity 11 below, even if the air inlet pipe and the air outlet pipe are installed reversely, the water cannot enter the patient's nasal cavity through the air-permeable film; dry oxygen enters the air inlet cavity 11 through the air inlet 12, and under the action of air pressure, the oxygen enters the water storage cavity 14 smoothly through the water-proof and air-permeable film 13, in this process, the air inlet flow is divided into countless small air flows by the water-proof and air-permeable film 13, the contact area between the oxygen and the water is larger, and the dry oxygen can be fully humidified in the water, so that the humidification effect of the oxygen is significantly improved; and since the oxygen inlet flow is divided into countless small air flows, there is no bubble burst sound when the large bubbles break the water surface, so that the noise is greatly reduced.

[0038] As shown in Figure 2 , Figure 3 , the oxygen inhalation pipe assembly 2 comprises an oxygen supply pipe 21, the lower end of the oxygen supply pipe 21 is sleeved on the air outlet 15, and the upper end of the oxygen supply pipe 21 is connected with a three-way pipe 22, the three-way pipe 22 is internally provided with a reversing switch 23, and the left and right two outlets of the upper end of the three-way pipe 22 are respectively connected with a nasal catheter 25 and a face mask oxygen inhalation pipe 24.

[0039] When the face mask oxygen inhalation patient drinks water or eats food, the reversing switch 23 can be adjusted to the nasal catheter 25, at this time, the reversing switch 23 blocks the outlet of the face mask oxygen inhalation pipe direction of the three-way pipe 22, and the oxygen supply pipe 21 and the nasal catheter 25 are in a conductive state; when the face mask oxygen inhalation is needed, the reversing switch 23 can be adjusted to the face mask oxygen inhalation, at this time, the reversing switch 23 blocks the outlet of the nasal catheter 25 direction of the three-way pipe 22, and the oxygen supply pipe 21 and the face mask oxygen inhalation pipe 24 are in a conductive state, so that the switching between the two oxygen inhalation modes is very fast and convenient.

[0040] The reversing switch is a prior art, and its specific structure and functions will not be described in detail in the embodiment.

[0041] Embodiment Two:

[0042] As Figure 6 shown in the second embodiment, compared with the first embodiment, other structures are unchanged, and the difference is that the safety pressure relief valve 19 is arranged above the water storage cavity 14.

[0043] The safety pressure relief valve 19 can release the pressure to the outside in time in the case that the pressure of oxygen suddenly increases due to the failure of the pressure reducing valve of the oxygen generator or the oxygen cylinder or other unexpected conditions, so as to ensure the safety of the patient in oxygen inhalation.

[0044] Embodiment three:

[0045] As Figure 7 , Figure 8 shown in the third embodiment, compared with the first embodiment, other structures are unchanged, and the difference is that the support protection structure 131 is arranged on the upper and lower sides of the water-proof and air-permeable membrane 13, and the support protection structure 131 is a spun-bonded non-woven fabric.

[0046] The protection structure 131 can make the water-proof and air-permeable membrane 13 bear greater pressure without being damaged, and improve the service life.
