Description

Novel pharynx back wall bloodletting suit

Technical Field

The utility model belongs to the technical field of the wall bloodletting behind the pharynx, especially, relate to a novel wall bloodletting suit behind pharynx.

Background

The blood-letting puncture method is a practical acupuncture therapy, which can quickly and accurately puncture the acupoints or blood vessels of specific parts of a patient through a sharp needle to release a small amount of blood, so as to achieve the purpose of treating diseases. The method has the effects of promoting blood circulation, removing blood stasis, relieving pain, inducing resuscitation, refreshing mind and the like, and is widely applied clinically.

Different from the common filiform needle, the existing general bloodletting needle is thicker and shorter, which is convenient for the operator to quickly prick the operated part by applying force. The traditional phlebotomy therapy adopts a three-edged needle, and because of repeated use, the three-edged needle needs to be disinfected, and also leaves infection hidden troubles for clinic. Therefore, the disposable blood taking needle is commonly used in clinic at present, overcomes the hidden trouble of nosocomial infection, is convenient to operate and does not need repeated disinfection.

Although the problem that the three-edged needle consumes time and labor in operation and disinfection is solved by the existing blood taking needle, the disposable bloodletting needle is convenient and fast to body surface bloodletting, and the bloodletting operation of a special area of a human body is still not feasible. For example, sublingual vein bloodletting and throat wall bloodletting, the suit suitable for the rear wall bloodletting is designed to improve the following problems in clinic:

(1) a large amount of manpower is consumed: the pharyngeal wall is used for bleeding, a patient needs to open the mouth with strength to expose the pharyngeal back wall, meanwhile, a doctor needs to use a tongue depressor to further expand the visual field of an operation area, and meanwhile, an assistant needs to be equipped to assist the operation through electric lamp illumination, and then the blood is discharged through prick. Ideally, the operator should be able to complete the entire procedure by himself.

(2) The tool is not adaptable: 1) specification problems: the distance from the outside of the oral cavity to the throat wall is far, because the existing bloodletting needle is too short, a plurality of 6-inch filiform needles are commonly used in clinic at present, cluster-shaped points prick the blood vessels of the throat wall, and the needle body of the long-type filiform needle is difficult to master the pricking strength due to the elasticity of metal materials, so the bloodletting effect is not ideal. 2) Function dispersion: auxiliary tools such as a tongue depressor, a long filiform needle and the like are required to be equipped, and the tools are not centralized and are inconvenient to operate.

(3) The visual field is not bright: because of the special position of the throat wall, even if the patient opens the mouth with force, the operator still has a clear enough operation visual field when the operation can not be performed, and still needs an assistant to perform illumination assistance, if the bloodletting instrument has an illumination function, the efficiency of the bloodletting therapy operation is greatly increased.

The doctor needs to assist in lighting in the operation process of the doctor, and can only perform acupuncture operation after pressing the tongue depressor, so that the operation efficiency of acupuncture bloodletting is reduced.
