Description

A kind of sputum sample processing device

technical field

The invention relates to the field of medical detection instruments, in particular to a device specially used for processing sputum samples.

Background technique

In the process of clinical and microbiological testing in hospitals, it is often necessary to collect, wash and digest the patient's sputum samples, and then enter the culture procedure to separate and culture the sputum samples. To obtain bacterial colonies, carry out bacterial identification and drug sensitivity detection, and provide the basis for clinical selection of antibiotics. The sputum sample collection cups currently on the market can only serve the function of transporting sputum samples, and cannot assist laboratories in the necessary washing and digestion of collected sputum samples.

Contents of the invention

In order to solve the above problems, the present invention provides a more convenient processing device for washing and digesting collected sputum samples.

The technical solution adopted in the present invention is: a sputum sample processing device, including a collection tube and a collection tube cover, characterized in that: a filter screen is also arranged in the collection tube, and the upper part of the filter screen is arranged with the mouth of the collection tube. There is a space for collecting sputum samples, and the lower part of the filter screen and the bottom of the collection tube are provided with a space for holding filtrate.

Preferably, the filter screen is recessed downwards and arranged in the collection pipe.

Preferably, the outer edge of the filter screen is hung on the nozzle of the collection tube.

Preferably, the sputum sample processing device further includes a cotton swab fixed on the collection tube cover, and the cotton swab extends into the collection tube through the collection tube cover to agitate the sputum sample on the filter.

The beneficial effects obtained by the present invention are: by setting a filter screen in the collection tube, the patient can directly put the sputum sample on the filter screen, and wash the sputum on the filter screen with physiological saline, which can conveniently and effectively treat the sputum. collection and processing. At the same time, cotton swabs are used to stir the sputum on the filter to further homogenize the sputum, which provides samples for the separation and culture of sputum.

detailed description

The present invention will be further described below in conjunction with the accompanying drawings.

As shown in FIGS. 1-2 , a sputum sample processing device of the present invention includes a collection tube 1 , a filter screen 2 , a collection tube cover 3 and a cotton swab 4 . The upper nozzle of the collection tube 1 is provided with an external thread, and the inner surface of the collection tube cover 3 is provided with an internal thread, and the external thread of the upper nozzle of the collection tube 1 can cooperate with the internal thread on the inner surface of the collection tube cover 3 for opening or closing. Seal collection tube 1. The collection tube 1 is provided with a downwardly recessed filter screen 2, the outer edge of the filter screen 2 is hung on the nozzle of the collection tube 1, and there is enough space between the upper part of the filter screen 2 and the nozzle of the collection tube 1 for the collection of sputum samples. There is enough space for the filtrate to hold between the bottom of the filter screen 2 and the bottom of the collecting tube. When the collection tube cover is screwed tightly, the filter screen 2 can be fixedly pressed on the collection tube nozzle. The cotton swab 4 is fixed on the collection tube cover 3 through the sealing hole 5 on the collection tube cover 3. Under the action of external force, the cotton swab 4 can move or rotate up and down in the sealing hole 5, and the cotton swab 4 passes through the collection tube cover 3. The sealing hole 5 of the tube cover 3 extends into the collection tube 1 to stir the sputum sample on the filter screen 2 . The cotton swab swab 4 can effectively stir the sputum sample on the filter to homogenize the sputum sample.

During use, the collection tube cover 3 is unscrewed, and the sputum sample is collected on the filter screen 2 in the collection tube 1 . Tighten the cap 2 of the collection tube to transport the sample to the laboratory. After the laboratory personnel receive the sample, they open the collection tube cover 3, and flush the sputum sample on the filter screen with a certain amount of normal saline in the laboratory. If it is a real sputum sample, the effective components of the sputum will remain on the filter, and the respiratory secretions will be washed down.

After rinsing with normal saline, take the laboratory digestive fluid and add digestive fluid to the filter screen 2 with the sputum sample. The sputum sample is agitated on the strainer 2 with a swab swab 4 . The sputum sample is digested into a homogenized sample, and the sputum sample is attached to the 4 heads of the cotton swab. The sputum sample on the swab swab 4 is placed on a glass slide for smearing, and finally the homogenized sputum sample is separated and cultured.

The basic principles, main features and advantages of the present utility model have been shown and described above. Those skilled in the art should understand that the utility model is not limited by the above-mentioned embodiments. The above-mentioned embodiments and descriptions only illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model There will also be various changes and improvements, and these changes and improvements all fall within the scope of the claimed utility model. The scope of protection required by the utility model is defined by the appended claims and their equivalents.
