Description
Technical Field
The utility model relates to the technical field of medical supplies, in particular to a special mask for mouth suction pipe operation.
Background
The mouth suction tube operation technology is one of basic manual technologies of biomedical related laboratory operations, is conventionally used for manual operations such as transferring or releasing biological samples such as various cells or embryos, is mainly used for fixing mammalian embryos such as mice, rats, pigs, cattle, sheep and monkeys and the like at present, is used for various manual operations such as subsequent embryo sorting operation, embryo injection, nuclear transplantation, stem cell transplantation and the like, and can also be used for sorting and transferring various single cells, such as the manual operation of single various embryonic stem cells, lymphocytes and tumor cells.
The method is characterized in that an operator holds the rear end of an air conduit by a mouth to control the pressure in an operation needle tube connected with the front end of the air conduit, the pressure in the operation needle tube connected with the front end of the air conduit is controlled to change by causing the change of tiny flexible pressure in the air conduit, and then the aim of sucking or releasing a cell or embryo sample at the front end of the operation needle tube is finally achieved by changing the pressure of the needle point of the operation needle tube.
However, in practice these methods require strict aseptic conditions, and therefore strict precautions, including wearing a mask, are necessary for the particular operator. However, the requirement of the special operation is not considered in the conventional municipal surgical mask at present, so that when an operator uses the oral suction tube in a laboratory, the operator inevitably wants to take another way to overcome the obstruction of the conventional surgical mask to the operation, for example, a small hole is cut in advance at the relevant part of the surgical mask before the operation, and the oral suction tube is convenient to pass through; or the lower part of the surgical mask is directly pulled up, a mouth suction pipe penetrates from the lower part of the mask, and the like, but the original protection effect of the mask is damaged by the methods, the mask needs to be treated in advance, and the workload of operators is increased.
SUMMERY OF THE UTILITY MODEL
1. Technical problem to be solved
For solving in the present conventional oral siphon operation, the operation of conventional oral siphon must carry out the protection of surgery gauze mask simultaneously, must destroy or change gauze mask own structure in the operation in-service use to oral siphon, influence the unmatched condition of each other of protective effect etc. special surgery gauze mask structure when considering reasonable change oral siphon operation, in order to reach when using conventional oral siphon, need not operating personnel and carry out special transformation to gauze mask or straw, gauze mask shape structure position does not change, guarantee the normal protective effect of gauze mask when carrying out the operation of conventional each item oral siphon.
2. Technical scheme
In order to achieve the purpose, the utility model provides the following technical scheme: a special mask for oral suction tube operation comprises a mask body; the surface of the mask body is provided with a through hole; the edge of the through hole is thickened; and a filter element is arranged in the through hole.
The mouth suction pipe operation special mask is characterized in that a reinforcing edge is fixed at the outer end of the through hole, and a mark is arranged on the reinforcing edge.
The special mask for operating the mouth suction pipe is characterized in that the through hole is circular.
The mouth suction pipe special mask for operation is characterized in that the reinforcing edge is internally covered with a cover plate.
The mask special for mouth and straw operation is characterized in that the cover plate is an airtight cover plate.
The mouth suction pipe operation special mask is characterized in that the reinforcing edge is a plastic ring and is pressed on the outer end of the through hole.
The special mask for mouth suction pipe operation is characterized in that the filter element is filter paper or filter gauze.
The special mask for operating the oral siphon is characterized in that the inner diameter of the through hole is not more than 5 mm.
3. Advantageous effects
In conclusion, the beneficial effects of the utility model are as follows:
(1) according to the mask special for the operation of the oral suction tube, when an operator performs conventional oral suction tube operation, the protection effect of the mask matched with the mask is more reasonable, the mask is more comfortable to wear, and the mask is more convenient and efficient to use and operate;
(2) the special mask for operating the oral suction tube is not required to be taken off and worn in the using process, so that the pollution to medical staff caused by the process of removing and wearing the mask can be avoided, and the medical safety in the operation process of the oral suction tube is ensured.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 to fig. 3, the present invention provides a technical solution: a special mask for oral suction tube operation comprises a mask body; the surface of the mask body is provided with a circular through hole, and the inner diameter of the circular through hole is 3 mm; the edge of the through hole is thickened, a reinforcing edge is fixed at the outer end of the through hole, and a mark is arranged on the reinforcing edge; and a filter element is arranged in the through hole.
Preferably, strengthen the border endotheca and have the cover plate, just the cover plate is ventilative cover plate, and when avoiding not using the mouth straw, the dirty material in external world passes through medical staff's respiration, adsorbs on the filter core, and then when the filter core was inserted to the through-hole, led to the fact the pollution to mouth straw surface, influenced the operation result.
Preferably, strengthen the border for the plastics circle, and the gland is in the through-hole outer end has the advantage in a plurality of aspects such as the quality is light, intensity is high, low price and simple to operate.
When the mask is used, the cover plate 5 is firstly uncovered, then various middle suction pipes are used for puncturing the filter element 3 to pass through the whole through hole 2, and due to the fact that the outer edge of the through hole 2 is thickened and reinforced, the rest parts of the mask body 1 except the through hole 2 cannot be damaged in the using process, and the sterile protection effect can still be achieved.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
