The invention discloses a detachable liquid-collecting type sputum suction device, which comprises a liquid-collecting bottle, a negative-pressure suction tube and a collecting tube. The negative-pressure suction tube is connected with the negative-pressure device and the liquid-collecting bottle. The suction port of the bronchoscope is connected, and the liquid collection bottle includes an upper cover, a lower cover, a collection bottle and a sampling test tube; Semi-closed type, the cavity between the outer bottle and the isolator is sealed at the lower ends of the two, and the unsealed space at the lower end of the outer bottle is used for the passage of the sampling test tube; the sampling test tube is nested in the collection bottle The inside of the isolation body, the lower end of the sampling test tube is sealed, and the outer wall of the lower end of the sampling test tube is attached to the lower end of the outer bottle; Cap the test tube connected to the sampling test tube. The invention integrates common sputum suction and sample collection, and achieves the purpose of collecting sputum samples accurately without pollution.

The invention discloses a sputum pot with a smearing function. The sputum pot comprises a small cover, a duck-mouth type large cover, a bottle body, a ball and an elastic bracket, wherein the small cover is detachably connected to the top of the duck-mouth type large cover in a sealing manner; the bottom of the duck-mouth type large cover is detachably connected to an opening of the bottle body in a sealing manner; a flat mouth part with an inner hole which gradually becomes small is arranged at the top of the duck-mouth type large cover; a coating surface with a liquid outlet is arranged on the top end of the mouth part; the elastic bracket is mounted in the mouth part; a concave pit is formed in the top of the elastic bracket; the bottom of the ball is supported by the concave pit; one small part of the ball is exposed out of the liquid outlet of the coating surface; the inner diameter of the liquid outlet is smaller than the diameter of the ball. On one hand, the efficiency of homogenized smearing is improved and the risk of contacting a sputum specimen by an operator is reduced; on the other hand, the amount of the smeared sputum specimens in each time is in a certain range and the smearing is uniform so that the smearing operation can easily realize standardization, the random errors are reduced and the production efficiency is improved.

The invention discloses an automatic sputum specimen smearing instrument. The automatic sputum specimen smearing instrument comprises a shell and a controller, wherein a glass slide accommodating chamber, a smearing chamber and a staining chamber are arranged inside the shell from the center to the edge in sequence, a slide outlet chamber is arranged outside the shell, a glass slide accommodating disc is arranged in the glass slide accommodating chamber, and a first lifting device is arranged between the bottom of the glass slide accommodating disc and the shell; an annular accommodating disc and a smearing device are arranged in the smearing chamber, a staining fluid bottle, a water pipe, a staining fluid collecting box and a drying device are arranged in the staining chamber, and a first pair of sliding rails, a second pair of sliding rails, a third pair of sliding rails and a fourth pair of sliding rails matched with one another are arranged in the glass slide accommodating chamber, the smearing chamber, the staining chamber and the slide outlet chamber respectively. By the adoption of the automatic sputum specimen smearing instrument, smearing, staining, drying and cleaning of a sputum specimen can be achieved automatically, operation is easy and convenient, and time is saved; opening and closing of a bottle cap and smearing are achieved through a smearing device, operation is easy and convenient, and cost is saved.

The invention discloses a centrifugal sputum case for induced sputum tubercle bacillus detection and belongs to the technical field of medical treatment detecting appliances. An existing sputum case is small in size and cannot be sealed, the sputum liquid is easy to leak outside so as to lead to tubercle bacillus dispersion and affect the detection effect of tuberculosis; the centrifugal sputum case disclosed by the invention can overcome these problems. The centrifugal sputum case comprises a sputum remaining cup, a sputum storage pipe body, a cock base, an inner pipe device and a sputum storage pipe cap, wherein the sputum storage pipe body is an integral test pipe comprising a conical top and a cylindrical bottom part which are in circular arc transition connection; the circular arc transition part of the inner wall of the sputum storage pipe body is provided with the cock base; the sputum remaining cup is installed in an annular groove at the inner side of the cock base; the cock base is also provided with the inner pipe device; the sputum storage pipe cap can directly cover the sputum storage pipe. The centrifugal sputum case is scientific and reasonable in structure, is low in cost, is simple, convenient and rapid to operate, is high in practicability, integrates sputum remaining and detection, shortens the sputum remaining time greatly, enhances the detection efficiency, reduces the re-pollution rate of a sputum specimen, and reduces the probability of infecting workers with tuberculosis.

The invention discloses a preparation method of a secretory type Rpf factor based on a transformant and application thereof. On the basis of constructing an exogenous expression vector pPIC-Rpf, the exogenous expression vector is converted into Pichia methanolica to prepare a recombinant, and the Pichia methanolica recombinant of a secretory type Rpf protein is obtained by resistance screening. APichia methanolica expression system can persistently secrete the Rpf protein with biologic activity; the protein can promote the resuscitation of mycobacterium smegmatis dormant bacteria and the growth of Mycobacterium tuberculosis (MTB) H37Ra, promotes the growth of the MTB in the sputum specimens of clinical TB (tuberculosis) patients and can be used for the rapid diagnosis of clinical TB.
