Description

Endocrine sample censorship nursing device

Technical Field

The invention relates to a medical examination auxiliary device, in particular to an endocrine sample submission nursing device.

Background

Endocrine patients mostly suffer from endocrine disorders and maladjustment, so in the pathological examination and reexamination process, the secretion of tissues, organs and other parts needs to be sampled and checked; the most common secretion extraction method is that the cotton swab is dipped and then placed in a test tube for storage and transportation, but the method is easy to adhere the secretion at the head of the cotton swab to the inner wall of the test tube, especially in the process of inspection and transportation, the cotton swab is easy to shake in the test tube, and a sample is smeared on the inner wall of the test tube, so that the inspection dosage and effect are influenced; aiming at the technical problem, in the prior art, some test tube plugs capable of fixing cotton swabs exist, but the cotton swabs are required to be inserted into the test tube plugs when the test tube plugs are used, and the cotton swabs can touch the heads of the cotton swabs carelessly, so that inconvenience and certain medical safety hidden danger exist in the actual operation process; in addition, some similar devices need to use matched cotton swabs, test tubes and the like, are not suitable for common cotton swabs, do not better solve the problems of convenience in sample extraction and storage and safety in inspection and transportation, and bring about great increase of medical cost.

In addition, due to the particularity of the secretion extracted from part of diseases, the stability of the flora of the sample needs to be ensured in the processes of preservation and inspection so as to prevent the quality change or the quantity change of the sample, and different technical means such as low-temperature storage, gas (oxygen and carbon dioxide) blocking and the like are generally adopted according to actual requirements; at present, a large number of sample containers are stored in a storage box meeting the conditions, but the method cannot interfere with gas in the test tube, so that the sample flora in the test tube still generates a certain amount change to influence the normal test result.

Disclosure of Invention

In order to overcome the technical defects in the prior art, the invention provides an endocrine sample submission nursing device, which aims to solve the problems that the conventional endocrine sample submission device is inconvenient in sample extraction and storage operation, a cotton swab is difficult to effectively fix, gas in a test tube cannot be blocked, and the applicability of the device is poor.

The technical scheme for solving the problem is as follows: the test tube plug comprises a test tube and a test tube plug, wherein the test tube plug consists of a groove body and a surrounding plate arranged on the periphery of the groove body, the upper end and the lower end of the groove body are communicated, the horizontal sections of the groove body and the surrounding plate are respectively in an open ring shape, the width of a groove opening of the groove body is smaller than the diameter of an inner ring of the groove body, the ring-shaped middle part of the groove body is connected with the ring-shaped middle part of the surrounding plate through a vertical plate, and when the surrounding plate is stressed and folded inwards until the horizontal section of the surrounding plate is in a closed circular shape; the inner side of the enclosing plate is provided with an arc-shaped plate which is arranged at the groove opening of the groove body and the axis of the arc-shaped plate is vertically arranged, the opening direction of the arc-shaped plate is consistent with the direction of the groove opening of the groove body, two side ends of the enclosing plate and two side ends of the arc-shaped plate are respectively and correspondingly connected through upright straight plates one by one at the same side, the inward elasticity of the enclosing plate acts on the arc-shaped plate through the straight plates to enable the arc-shaped plate to be attached to the groove opening of the groove body, when the enclosing plate is stressed and folded inwards, the arc-shaped plate is pushed by the straight plates to move towards the inner side of the groove body, the groove opening of the groove body is extruded by the arc-shaped plate to generate elastic expansion deformation and open, and when the enclosing plate is completely folded, namely the; the enclosing plate, the arc-shaped plate and the straight plate are connected to form a clamping piece, the outer side of the clamping piece is wrapped by a silica gel layer, the lower end of the silica gel layer is closed, and the lower ends of the clamping piece, the groove body and the upright plate are completely wrapped to realize sealing; when the coaming is stressed and completely folded, the silica gel layer between the two straight plates is completely attached to realize sealing.

The cotton swab fixing device is convenient and fast to operate, and the cotton swab can be fixed only by correspondingly placing the cotton swab into the inner side of the arc-shaped plate and then folding the enclosing plate; different from the cotton swab insertion type fixing method adopted in the prior art, when the test tube plug is used, an external force acts on the test tube plug, and the cotton swab does not directly receive the force, so that the accidental touch on the head of the cotton swab is effectively avoided, and the accidental risks such as breakage of the cotton swab and the like can also be avoided; meanwhile, the silica gel layer on the inner side of the arc-shaped plate has good elastic deformation performance, so that the inner side of the arc-shaped plate can be matched with common cotton swabs of different specifications, and the silica gel layer has wider applicability.
