Description

Palpation film spraying fingerstall, preparation method and device

Technical Field

The invention relates to the field of traditional Chinese medicine diagnostics, in particular to a palpation film spraying fingerstall, a preparation method and a device.

Background

Palpation is a method of physical examination using the fingers or touch of the physician. The physical characteristics of the body surface (skin and subcutaneous tissue, etc.) and the organs (heart, lung, liver, spleen, kidney, uterus, etc.) can be known by touching, pressing and pressing the examined part. Such as size, contour, hardness, tenderness, mobility, hydrodynamics and the like, can help doctors provide visual important basis for judging whether the examined part and the viscera are diseased or not, and the relationship among the anatomical part, the viscera and the tissues needs to be closely combined for analysis during palpation, so that the method has diagnosis value.

The pulse-taking is performed by touching the pulse at different parts of the bodyPulse conditionA variant of the method of resection. Also known asPulse feelingPulse diagnosis, pulse pressing and pulse holding. The formation of pulse conditions andzang-fu organsIf qi and blood of the zang-fu organs are affected, the blood vessels will be affected and the pulse condition will change. The pulse diagnosis is clinically used to infer the prognosis of disease. Clinically, the pulse-taking time, the body position of the patient, the fingering and the finger strength of the doctor are mainly grasped,the pulse-taking time is limited to that each side pulse beats not less than 50 times, and the pulse-taking can be correctly carried out only by knowing the change condition of the pulse condition of healthy people. The pulse diagnosis adopted by ancient medicine in China in the aspect of disease diagnosis is a unique pulse diagnosisDiagnostic methodPulse, a Chinese medicine "Four diagnostic methodsOne of the essential objective evidences for syndrome differentiation and treatment is Wang, Wen and Ji.

In palpation and pulse taking, doctors commonly use medical sterile gloves and finger sleeves as tools in palpation and pulse taking, but the thickness and the shape of the existing medical gloves and finger sleeves can influence the touch feeling of the doctors in palpation, especially the touch feeling in traditional Chinese medicine pulse feeling and palpation, and especially the accuracy of traditional Chinese medicine pulse feeling and palpation results; the traditional sterile gloves and finger sleeves have poor air permeability, so that the wearing comfort of a doctor is influenced; however, if gloves are not used, the contamination of doctors with skin diseases, infectious diseases, germs and other harmful microorganisms can be increased, and in the modern times that the hygiene is generally regarded as important, the patients are worried that infectious diseases, viruses and microorganisms can be transmitted to the patients through the fingers of the doctors, so that certain mental burden is caused, and the risk of actually suffering from infection also exists.

Most of the existing film spraying solutions are used for wound surfaces and have the function of treating local diseases, but no film spraying fingerstall which is specially sprayed on fingers by doctors and used for cutting off the transmission path of diseases is available.

In order to solve the problems, the invention provides the traditional Chinese medicine formula film spraying fingerstall with the effects of clearing heat, removing toxicity, resisting viruses, sterilizing and the like. Can completely replace the functions of the traditional fingerstall and glove in pulse diagnosis and palpation. So that doctors can have one more safety guarantee and one less risk of feeling and spreading diseases when performing pulse-taking, palpation and other conventional contact diagnosis on patients. Meanwhile, the film-spraying finger stall device for palpation is matched with the device, so that the film is easier to form, the film forming time is shortened, the time for doctors to diagnose and treat diseases is saved, the working efficiency is improved, and the like.

Polyvinyl alcohol (Henan Ding Xiang chemical products Co., Ltd.); sodium carboxymethylcellulose (yokly chemical company, ny city); glycerol (Shanghai Bitsu chemical Co., Ltd.); polyethylene glycol (haian petrochemical plant, Jiangsu province); the test is carried out by a conventional instrument.

2. Screening of blank matrices

2.1 matrix preparation: respectively taking polyvinyl alcohol and sodium carboxymethylcellulose, adding a proper amount of purified water, heating in a water bath at 100 ℃ for 25 minutes, fully dissolving the matrix, and preparing into corresponding mass concentration for later use, wherein the results are shown in table 1.

2.2 comprehensive evaluation: the film forming material is comprehensively evaluated by 3 indexes of film forming property, film toughness and adhesiveness, and the film forming material is graded by the excellent, common and poor indexes.

2.2.1 film Forming: the film is graded in a way that the film is extremely thin, moderate and thick, the film forming is influenced after the medicine is added into the film forming material solution for forming the extremely thin film, and the grade is poor; the film was thin, medium, thick rated good.

2.2.2 membrane elongation times, namely integrating membrane elongation times and membrane hand feeling softness and hardness, and dividing the membrane elongation times into 3 grades, wherein the membrane elongation times are more than 1, and the membrane hand feeling softness is better in toughness; the elongation times of the film are 1, and the film has soft hand feeling and general toughness; the film elongation times could not be measured and the film had a hard hand and poor toughness.
