Description

Hygiene mask for anesthesia machine

technical field

The utility model relates to a medical mask, in particular to a hygienic mask for an anesthesia machine, which can avoid cross-infection during the use of the mask.

Background technique

The anesthesia machine is the main device in the anesthesia tool, which is mainly used to control the inhalation of anesthesia gas during general anesthesia; the anesthesia machine delivers the oxygen, anesthesia gas and steam of the anesthesia machine with controlled flow and concentration to the patient connected to the anesthesia machine In the breathing circuit, the mask of the anesthesia machine is the terminal device for delivering steam, and the medicine is introduced from the patient's mouth and nose.

The existing anesthesia machine mask has a relatively simple structure, which includes a round mask, an inflatable air bag is arranged on the edge of the round mask, and an anesthesia tube interface connected to the anesthesia machine is opened on the round mask, and the doctor needs to press the mask when using it. Put it on the patient's face, and inflate the airbag, so that the airbag part can completely fit on the edge of the patient's mouth and nose, and form a relatively closed environment in the mask, so that the drug vapor can form a circuit with the human respiratory system in the mask, and continuously release the drug The steam is inhaled into the body to achieve anesthesia effect.

After the anesthesia mask is pressed on the patient's face, it needs to be completely fitted to ensure the sealing performance of the mask and prevent air leakage from the side and make it difficult to pressurize and oxygenate. Under normal circumstances, anesthesia steam enters the patient's body from the nose, but for some patients, such as nose problems or respiratory system damage, it is difficult to achieve a good anesthesia effect in a short period of time with only nasal breathing; Unintentional coughing, salivation, etc. will pollute the mask; although there are disposable masks available on the market, they are expensive, of uneven quality, and have poor reliability during use.

Contents of the invention

Aiming at the above-mentioned problems in the prior art, the purpose of this utility model is to provide a hygienic mask for an anesthesia machine, which can improve the efficiency of inhalation anesthesia to a certain extent, and at the same time ensure the sanitation of the mask.

In order to achieve the above tasks, the utility model adopts the following technical solutions:

Detailed ways

Present anesthesia machine face mask 4 structure, function are single, adopt the mode of nasal inhalation to carry out anesthesia mostly, and for some patients who are not convenient for nasal inhalation, the use of face mask 4 is just restricted. This program proposes a new type of anesthesia machine mask 4:

A hygienic mask for an anesthesia machine, comprising a mask 4, an air bag 3 is arranged around the edge of the mask 4, and an anesthesia tube interface 6 that penetrates the mask 4 and is used to connect with the pipeline of the anesthesia machine is arranged on the mask 4, and the anesthesia tube One end of the interface 6 extending into the inside of the mask 4 is connected with a telescopic tube 9, and a dental tray 10 is arranged in the patient's mouth, and a breathing tube 1 is connected on the dental bracket 10, and one end of the breathing tube 1 is stretched into the patient's mouth, and the other end of the breathing tube 1 is connected to the patient's mouth. Telescopic tube 9 is connected.

On the basis of the structure of the original anesthesia machine mask 4, this program is provided with a dental tray 10 and a structure of the telescopic tube 9. The telescopic tube 9 can be regarded as an extension of the anesthesia tube interface 6. The telescopic tube 9 is arranged in the mask 4 and can be adjusted. its length. The effect of the tray 10 is to prop the patient's mouth open and keep a constant space between the upper and lower gums to facilitate the insertion of the breathing tube 1 . The breathing tube 1 is stretched into the patient's mouth, and can directly transport the anesthetic gas to the patient's throat, making it easier for the anesthetic liquid to enter the human body with the breathing process. After the dental tray 10 is set, connect the telescopic tube 9, and the telescopic tube 9 can easily adjust the length according to its telescopic characteristics, so as to be convenient to be connected with the breathing tube 1. In addition, a side port can also be provided on the telescopic tube 9, so that a part of the anesthetic gas can also be inhaled through the nasal cavity, providing more diverse inhalation methods.

This program further proposes a kind of dental tray 10, as shown in Figure 3, comprises upper dental tray 101 and lower dental tray 102, the longitudinal section of upper dental tray 101 and lower dental tray 102 is U-shaped, upper dental tray 101, The lower tray 102 is adapted to the shape and structure of the maxillary central incisor and the mandibular central incisor respectively, and the upper tray 101 and the lower tray 102 are connected by a fixing plate 103 .

10 sets of dental brackets are placed on the outside of the teeth to protect the teeth and simultaneously spread the upper and lower gums, leaving enough space between the teeth to arrange the breathing tube 1 . The upper tray 101 and the lower tray 102 do not need to be too large, as long as they can wrap the central incisor; the longitudinal section of the tray 10 is U-shaped, which is convenient for fitting on the teeth. A fixed plate 103 is arranged between the upper tooth tray 101 and the lower tooth tray 102, and the fixed plate 103 plays a supporting role and is convenient for setting the breathing tube 1 at the same time.

The breathing tube 1 is a section of circular tube, and the opening of one end of the breathing tube 1 protruding into the mouth can be larger, so as to facilitate the diffusion of medicine;

The breathing tube 1 and the telescopic tube 9 are detachably connected, such as a plug-in method, which is convenient for installation and cooperation between masks 4 of different sizes and dental trays 10; the telescopic tube 9 adopts a threaded hose.

A catheter 7 is arranged on the side of the fixed plate 103, and one end of the catheter 7 stretches into the patient's mouth and is connected with a Y-shaped or U-shaped suction pipe 2, and the liquid suction pipe 2 is distributed with liquid-permeable holes 11; The other end of the tube 7 passes through the mask 4 outside.

Because excessive body fluid may be secreted in the patient's mouth, if it is not processed, it will flow down with the corners of the mouth and accumulate in the face mask 4, causing pollution. The suction tube 2 is placed in the mouth of the patient and can be pressed on both sides of the tongue. There are a plurality of liquid permeable holes 11 distributed on the liquid suction tube 2, so that body fluid can flow into the liquid suction tube 2 through the liquid permeable holes 11, and then It is diverted from the catheter tube 7; in order to make the body fluid have a better diversion effect, a negative pressure device is provided at the end of the catheter tube 7 passing through the outside of the mask 4, such as a negative pressure suction ball, which is pinched regularly Inhale the balloon so that excess body fluid in the mouth is sucked out.

During the anesthesia process, the patient may involuntarily cough, sneeze, etc. if he feels unwell, but the mask 4 pressed on the face cannot be removed, and the anesthesia process will be interrupted after being removed. In this case, saliva, secretions, etc. in the patient's mouth may splash inside the mask 4 and cause contamination to the mask 4 .

For this situation, this program is provided with protective pad 5 in mask 4, and as shown in Figure 2, protective pad 5 can be a round pad, also can be bowl-shaped pad, adapts to the shape inside mask 4 and gets final product, material Face cloth, sponge, etc. can be used as a disposable product. A through hole is provided in the middle part of the mask 4 to facilitate the passing of the telescopic tube 9, and the telescopic tube 9 passes through the through hole on the protective pad 5 to be provided.

When the patient uses the mask 4, at first the new protective pad 5 is set on the telescopic tube 9, the patient's mouth is opened, and the patient is instructed to bite the mouthpiece 10 to adjust the position of the breathing tube 1, and put the suction tube 2 On both sides of the tongue in the patient's mouth; at this time, the telescopic tube 9 is docked with the breathing tube 1, and then the air bag 3 is filled with gas through the inflation port 8, and the anesthesia process can be started by pressing it on the patient's mouth and nose.
