Description

Invasive medical equipment mask

The invention relates to a mask for invasive medical equipment, in particular to a mask technology which can achieve better human medical visit and respiratory airtightness.

According to the general medical respiratory mask, it is mainly used for patients with respiratory symptoms such as asthma, acute respiratory failure, psychogenic pulmonary edema, chronic obstructive pulmonary disease, neuromuscular disease, thoracic deformity, and sleep apnea. Wearing is mainly to enable patients to achieve normal breathing function with the aid of medical equipment.

In general, if the patient is only relying on the nose to breathe, a nasal mask can be used. If the patient uses mouth breathing, an orona-nose breathing mask can be used; or a full-face breathing mask. The main structure of the respiratory mask consists of a mask body that covers the entire nose and mouth of the patient. In the specific use, the patient can cover the mouth and nose by wearing the mask body, and connect the mask body and the breathing device (such as a drug inhaler or an oxygen supply device) with a pipeline. The medicine or oxygen is input through the nose and mouth of the mask body to help the patient open the respiratory tract so that the patient can maintain normal breathing operation.

The difference between a so-called invasive medical mask and a non-invasive medical mask is that the invasive medical mask is provided with at least one opening for the specific aperture size of the medical access device (such as an endoscope or a gastroscope). Hole, here, you can wear a mask in the patient In the case of the body, the required in vivo medical visit inspection is performed simultaneously.

In addition to this, as is currently known, the types of conventional invasive medical masks and the resulting deficiencies are as follows:

1. Invasive medical mask (VBM), although it only has a circular opening in the silicone dome of the mask, it is better in air tightness, but it is necessary to select a mask with a suitable aperture for the diagnosis needs (eg 2, 3, Four sizes of valve plates (VBM), such as 5 and 10 mm, are available for doctors to choose. If there is no stock of suitable aperture masks, choosing too loose aperture may cause air leakage. Choosing too tight aperture is not easy to operate; therefore, This conventional structure not only causes an increase in the cost of purchase, but also causes wasteful use of the breathing mask that is not needed; in emergency situations, it is necessary to reinstall the aperture valve to increase the risk of improper installation and installation time. Increase the delay in the timing of diagnosis and treatment.

2. Invasive medical mask (ISG), which is equipped with three different sizes of apertures in the mask and three-line valves on the three openings. This conventional structure can reduce the cost of purchase and no matter which aperture is inserted. The size of the medical tube can be used, but the mask is not tightly sealed, which may affect the therapeutic effect of the patient and the unsmooth breathing caused by poor oxygen supply. If used in combination with anesthetics or other drugs, it may also cause the risk of infection or inhalation of non-patient medical personnel.

3. Invasive medical mask (PHILIPS), which is an S-shaped groove with a hole size in the mask, so the conventional structure can only be inserted into a medical tube of a certain aperture size, and the gastroscope with a larger intubation size is Unable to apply, resulting in inconvenience and troubles in selection.

4. Invasive medical mask (POM; Panoramic Oxygen Mask), which is tied to A plurality of cross-shaped grooves of different aperture sizes are provided at different positions of the mask. Although the conventional structure can reduce the purchase cost and can be used regardless of which diameter of the medical tube is inserted, the mask is not airtight and can only be used. The use of the pressure state is its disadvantage; in addition, if the cross-shaped groove away from the nose and mouth is selected as the inlet for the medical tube insertion, the medical treatment due to the difficulty in extending the tube into the mouth, nose and the like may occur. Inconvenience and troubles arise.

According to the analysis of the upper induction, how to develop a set of invasive medical mask technology with good air tightness, medical timeliness and multiple aperture size selection functions has become an urgent solution and challenge for the relevant technical field.
