Abstract

A smear device for testing phlegm specimens in medicine is mainly composed of a rod body (1) and a brush part (2), the brush part (2) is mainly arranged on the end portion of the rod body (1) and embedded into a hole on the end portion of the rod body (1), and the brush part is fixedly clamped and pressed by an embedding sheet (3). The smear device is convenient to use, the obtained smear is proper in thickness and even in distribution, relevance ratio of causative agents in a specimen in microscopic examination can be improved, and the smear device is made of plastics and the like so that the smear device is not apt to mildew and cannot pollute the specimens.

Description

The smear device

The smear device that a kind of medical test humoral specimen of technical field is used is meant a kind of smear device that is used for sputum specimen check usefulness especially.

The various humoral specimens of background technology clinical medical inspection are used the check again behind smear on the microslide of oese, cotton swab or bamboo let always.The World Health Organization (WHO) as one of five tactful fundamentals of DOTS, is used for microscope phlegm plate coating checking to find and diagnosing transmissible pulmonary tuberculosis, evaluation curative effect and evaluation epidemic situation prevention and control effect.At present, even uniting the relevant documents of editing and publishing such as " phlegm smear for microscopic examination normalizing operation and quality control (assurrance) manuals " with CDC, up-to-date prevention and control of diseases office of the Ministry of Public Health all also recommends to use bamboo let to make the sputum specimen smear.

The proofer makes the sputum specimen smear with end coarse bamboo let or oese, even careful the making, smear also is that thickness differs, maldistribution.When smear is blocked up; Pathogen on the smear is covered can not be by clear view; It is very few that smear is crossed the specimen amount of observing in thin then each oily mirror visual field, all can influence detecting of pathogen so smear is blocked up or mistake is thin, thereby influence the discovery of some infections sources such as infectiousness pulmonary tuberculosis patient.Cotton swab is prone to the liquid on absorption sputum specimen surface, and the phlegm smear sampling scope made from it is not extensive, also can reduce the recall rate of pathogen.In addition, bamboo let is prone to mouldy pollution sample, causes the microscopy misidentification or cultivates pollution.

Summary of the invention for the quality of the smear that improves the clinical examination sputum specimen, reduce the smear manufacture difficulty, improve microscopy pathogen recall rate, reduce mould contamination, the present invention proposes a kind of smear device, this smear device smear is easy to operate, it is better to be coated with tablet quality.

The present invention solves its technical matters, proposes the smear device that a kind of clinical medical inspection sputum specimen is used, and mainly is made up of with hairbrush portion 2 body of rod 1, and said hairbrush portion 2 mainly is arranged at the end of the body of rod 1.

The said body of rod 1 can be plastic material, and length is advisable with 10 to 20 centimetres, and hairbrush portion 2 can be materials such as animal hair, vegetable fibre, plastic optical fibre or tinsel.The bristle lengths that hairbrush portion 2 exceeds the body of rod 1 is controlled to be 2 to 8 millimeters, because the sample of hairbrush portion 2 long absorption can too much cause smear blocked up and to be coated with plate shape wayward, crosses thin and inconvenient sample coating and disperses otherwise then be coated with sector-meeting.

The form that said hairbrush portion 2 is arranged at the body of rod 1 end can be the continuity syndeton.As can adopt the electrostatic spinning mode to stick with glue agent the two is bondd; Hairbrush portion 2 is processed with the body of rod 1 usefulness thermoplastics injection moulding.

The form that said hairbrush portion 2 is arranged at the body of rod 1 end can be chimeric syndeton.For example the bristle of hairbrush portion 2 can embed stick with glue in the body of rod 1 end hole that agent is adhesively fixed or with empiecement, carve son etc. and block the hole wall fasten bristles; Perhaps the bristle of hairbrush portion 2 and the body of rod 1 combine through hot melt, can be in the body of rod 1 injection molding process and hairbrush portion 2 converged fixed that preset.

The advantage of this smear device has; The specimen amount that bristle adheres to is suitable, the flexible smear that makes of bristle is easy to operate; Make that the sample thickness suits, is evenly distributed on the smear; The field of microscope of smear efficient clear, that observe improves, and can improve the microscopy recall rate of pathogen, and the smear thickness of making such as bamboo let, oese differs; The pathogen particle that the bristle of smear device can puncture effectively and contact and be stained with the sputum specimen internal package makes that sampling is extensive, representative, also can improve the microscopy recall rate of pathogen, and cotton swab adsorbs the sample surface liquid easily, and the smear sampling is not extensive; The smear device of the plastic production pollution sample that is difficult for going mouldy.

Appended drawings mark 1 is that the body of rod, 2 is that hairbrush portion, 3 is empiecement.

Fig. 1 is the continuity syndeton, for hairbrush portion 2 relies on the fixing smear device structural representation of adhesive bonding with the body of rod 1;

Fig. 2 is the continuity syndeton, for hairbrush portion 2 and the body of rod 1 together by the smear device structural representation of mold injection molding;

Fig. 3 is chimeric syndeton, and empiecement 3 is pushed down the doubling bristle and blocked the smear device structural representation of the tube wall of the body of rod 1.
