Description

Mask used in tissue slice manufacturing

Technical Field

The utility model relates to a mask, in particular to a mask used in tissue section manufacturing.

Background

The disposable medical mask has the effects of resisting liquid, filtering particles, bacteria and the like, and is a medical protective article. The medical mask has strong resistance to bacteria and viruses, good waterproof performance and particle filtering efficiency, and can be used for preventing the spread of influenza and respiratory diseases. But at present, no disposable protective mask which can be used when tissue slices in the pathological working process is available.

In the pathological working process, the tissue section preparation is a continuous and complex process which mainly comprises multiple links of fixing, material taking, dehydration, transparence, wax dipping, embedding, slicing, sticking, baking, dyeing, sealing and the like, and all the links are very important. In the process of making pathological sections, the phenomena of tissue section rolling, sticking, non-connection, fold of the tissue section, cracking of the tissue section and the like are frequently encountered during the section making process. The reason for this phenomenon is that the static electricity is increased when slicing due to over-high indoor temperature or air drying, and at this time, a pathologist often blows air to the wax sheet by using a mouth while slicing to improve the quality of the wax sheet, so that a high-quality tissue slice is produced, and the misdiagnosis rate is reduced or lowered. In actual operation, in order to prevent infection and wax foam entry nose, medical gauze mask can be worn by pathology technician, because the gauze mask face body of traditional medical gauze mask is integral, need repeatedly take off medical gauze mask during the blowing, otherwise can't blow, but, not only cause a great deal of inconvenience for pathology technician like this, but also have the risk of being infected with and wax foam entry nose.

SUMMERY OF THE UTILITY MODEL

The present invention is directed to a mask used in the preparation of a tissue section, which solves the above-mentioned problems of the prior art.

In order to solve the technical problem, the utility model provides a mask used for making a tissue section, which comprises a mask body, elastic bands are fixed on two sides of the mask body, a foldable air blowing cylinder is arranged in the middle of the outer side face of the mask body, the opening, attached to one side of the mask body, of the air blowing cylinder is larger than the opening, away from one side of the mask body, of the air blowing cylinder, an air blowing hole is formed in the position, corresponding to the air blowing cylinder, of the inner side face of the mask body, and an air blowing net film is fixed on the air blowing hole.

As a further improvement of the utility model, the air blowing cylinder is made of foldable soft plastic materials, a vertical memory crease is arranged on the air blowing cylinder in the middle along the length direction of the cylinder body, and the air blowing cylinder can be symmetrically folded and recovered along two sides of the vertical memory crease. The design can open and close the air blowing cylinder repeatedly, and is convenient for compression and storage.

As another structural improvement of the folding mode of the air blowing cylinder, a plurality of annular memory creases are circumferentially arranged on the air blowing cylinder along the cylinder body, and the air blowing cylinder can be compressed, folded and recovered from outside to inside along the annular memory creases.

As a further improvement of the utility model, the elastic band is a pullover type elastic band or an ear hanging type elastic band; the principle is just for the convenience of wearing of different users, adjusts the laminating of gauze mask body and human face according to individual condition, improves the use experience of wearing person.

As a further improvement of the utility model, the air blowing net film is made of air-permeable materials such as yarn, air-permeable cotton, nano film and the like, and the area of the air blowing net film is slightly larger than the area of an opening corresponding to the air blowing hole, so that the air blowing net film can be conveniently sewn with the mask body; the shape of the air-blowing net film can be set to be circular, rectangular or elliptical according to the use condition.

Compared with the prior art, the utility model has the beneficial effects that:

the utility model can ensure normal work in the pathological section process and protect operators (the mask is required to be taken off for blowing in the general pathological section process), prevent wax foam from contacting with skin to cause allergy, and reduce the risk of infection and wax foam entering the mouth and nose. And time can be saved, the working efficiency is improved, excellent tissue slices are manufactured, and the probability of misdiagnosis is reduced.
