Problems solved by technology

[0003] The breathing device in the prior art is inconvenient to install and use. The medical staff rely on experience to judge the amount of gas supplied by the air bag to the breathing mask, and cannot accurately grasp the tidal volume inhaled by the patient, and cannot obtain a better therapeutic effect. Some breathing devices do not have the function of filtering and purifying, which may cause patients to inhale dusty gas and aggravate their condition. In addition, the existing breathing devices do not have an alarm function, and the amount of gas supplied to patients is likely to exceed the limit, which cannot guarantee the safety of patients. For safe treatment, for this purpose, a simple respirator device with the function of accurately measuring tidal volume is proposed

Embodiment 1

[0051] The following is attached Figure 1-8 The present invention is described in further detail.

[0052] A simple respirator device with precise measurement of tidal volume, such as Figure 1-8 As shown, the airbag 1 is included, the bottom of the airbag 1 is communicated with an air inlet pipe 6, and the upper part of the airbag 1 is communicated with an air outlet pipe 7, and the inside of the air inlet pipe 6 is provided with a one-way valve 33, and the air outlet pipe 7. One end away from the airbag 1 is screwed inside one end of the L-shaped elbow 5, the other end of the L-shaped elbow 5 is connected to a filter device 2, and the side of the filter device 2 away from the L-shaped elbow 5 is connected to a A measuring device 3, the side of the measuring device 3 away from the filter device 2 is connected with a breathing mask 4;

[0053] The filtering device 2 includes a cylindrical shell 8 with one end screwed on the outside of the other end of the L-shaped elbow 5. ...

Embodiment 2

[0065] The difference from Example 1 is that the surface of the stainless steel wire filter screen 10 is also provided with an anti-corrosion layer, and the anti-corrosion layer is prepared by the following method:

[0066] Take the following raw materials and weigh them by weight: 20 parts of epoxy resin, 10 parts of titanium dioxide powder, 8 parts of p-toluenesulfonic acid powder, 8 parts of calcium carbonate powder, 5 parts of cobalt naphthenate, 1 part of silane coupling agent and water 30 copies;

[0067] S1, adding epoxy resin, titanium dioxide powder, p-toluenesulfonic acid powder and calcium carbonate powder into a ball mill for fine grinding until the particle diameter is not greater than 40um to obtain a mixed powder material;

[0068] S2. Add the mixed powder material and water prepared in step S1 into the reactor and stir for 25 minutes, then add cobalt naphthenate and silane coupling agent, and continue stirring for 15 minutes. The stirring speed is set to 700r / m...

Embodiment 3

[0074] The difference from Example 2 is the preparation of the anti-corrosion layer, and its specific preparation method is as follows:

[0075] Take the following raw materials and weigh them by weight: 25 parts of epoxy resin, 13 parts of titanium dioxide powder, 10 parts of p-toluenesulfonic acid powder, 9 parts of calcium carbonate powder, 7 parts of cobalt naphthenate, 2 parts of silane coupling agent and water 35 copies;

[0076] S1, adding epoxy resin, titanium dioxide powder, p-toluenesulfonic acid powder and calcium carbonate powder into a ball mill for fine grinding until the particle diameter is not greater than 40um to obtain a mixed powder material;

[0077] S2. Add the mixed powder material and water prepared in step S1 into the reaction kettle and stir for 30 minutes, then add cobalt naphthenate and silane coupling agent, and continue stirring for 17 minutes. The stirring speed is set to 800r / min, and the temperature is set to 90 ℃, to prepare anti-corrosion co...

Abstract

The invention discloses a simple respirator apparatus having a function of precisely measuring tidal volume. The simple respirator apparatus comprises an air bag. The bottom of the air bag is equippedwith an air inlet pipe in a communicating manner. Additionally, the upper part of the air bag is equipped with an air outlet pipe in a communicating manner. A check valve is arranged in the interiorof the air inlet pipe. One end, departing from the air bag, of the air outlet pipe is in bolt joint with the interior at one end of an L-shaped bent pipe. The other end of the L-shaped bent pipe is connected with a filter device. One side, departing from the L-shaped bent pipe, of the filter device is connected with a measuring device. One side, departing from the filter device, of the measuring device is connected with a breathing mask. The simple respirator apparatus is convenient to install and use. Medical staff can precisely master tidal volume inhaled by a patient in order to acquire better treatment effect. Gas supplied from the air bag to the breathing mask is filtered. Therefore, the patient is prevented from inhaling gas containing dust. The tidal volume supplied to the patient is effectively prevented from exceeding the upper limit. The safety treatment of the patient is effectively ensured. The simple respirator apparatus is worth of popularization and promotion.

Description

technical field [0001] The invention relates to the technical field of medical instruments, more specifically, it relates to a simple respirator device with the function of accurately measuring the tidal volume. Background technique [0002] Tidal volume (TV) refers to the volume of air inhaled or exhaled each time when breathing calmly. It is related to age, gender, volume surface, breathing habits, and body metabolism. The set tidal volume usually refers to the inspiratory volume. The setting of tidal volume is not constant and should be adjusted according to the patient's blood gas analysis. Under normal circumstances: adults: 8-10ml / kg, children: 6-10ml / kg. [0003] The breathing device in the prior art is inconvenient to install and use. The medical staff rely on experience to judge the amount of gas supplied by the air bag to the breathing mask, and cannot accurately grasp the tidal volume inhaled by the patient, and cannot obtain a better therapeutic effect. Some ...
