Description

Sampling device for clinical laboratory

Technical Field

The utility model belongs to the technical field of clinical medicine inspects, concretely relates to clinical laboratory uses sampling device.

Background

In three general examinations, stool examination is indispensable, and stool sampling generally includes three steps of collection, transportation and inspection. Currently, when a clinical laboratory samples stool, a doctor usually gives a cotton swab and an open disposable plastic test tube to a patient. After the patient defecates in the toilet, the cotton swab is inserted into the excrement sample, the cotton swab stained with the sample is inserted into the open disposable plastic test tube, after the operations are repeated for a plurality of times, enough excrement samples are left in the open disposable plastic test tube, and then the open disposable plastic test tube is taken into a laboratory for testing, so that the toilet stool is not sanitary and elegant, and is troublesome to operate. Moreover, air pollution is caused in the process from a toilet to a laboratory, pathogenic bacteria can be spread if excrement samples with infectious pathogenic microorganisms are encountered, and the standard sampling of the excrement samples is more important especially when infectious diseases are epidemic.

In addition, after receiving the stool sample, the medical care personnel vertically insert all open disposable plastic test tubes on the test tube rack, queue up one by one for inspection, thus greatly increasing the possibility of infection of the medical care personnel, and bringing serious life safety to the medical care personnel in case of encountering the sample of an infectious disease.

Detailed Description

The invention will be further explained with reference to the following figures and examples:

as shown in fig. 1, fig. 2 and fig. 3, the utility model discloses a sampling device for clinical laboratory, including sampling tube 3 and sample combination, utilize the sample combination to realize acquireing the shit.

The upper end mouth of pipe of sampling tube 3 is closed, the lower extreme is uncovered and is opened, and in the present case, sampling tube 3 is integrated into one piece's product, preferentially uses plastics to make. Bosses 3a are uniformly provided on the upper end portion of the outer wall of the sampling tube 3 along the circumferential direction, the number of the bosses 3a is preferably 3, and the bosses 3a are used for being held by the fingers of a patient so that the thumb of the patient presses the handle 1 downwards to expose the sampling cup 7.

The sample combination is including handle 1, lifter 5 and the sample cup 7 that from top to bottom sets gradually, and the equal coaxial setting of sampling tube 3, handle 1, lifter 5 and sample cup 7. As shown in fig. 2 and 3, the handle 1 is located above the sampling tube 3, the handle 1 is fixedly connected with the upper end of the lifting rod 5, and the lifting rod 5 is in sliding fit with the top of the sampling tube 3. The lifting rod 5 is sleeved with a pressure spring 6, the upper end of the pressure spring 6 is abutted against the upper end of the handle 1, and the lower end of the pressure spring is abutted against the upper end of the sampling tube 3. Under the action of the elastic force of the pressure spring 6, the handle 1 pulls the lifting rod 5 to slide upwards.

The upper end of the sampling cup 7 in the scheme is open, because the sampling cup 7 is used for containing and storing excrement of a patient. Meanwhile, the outer side wall of the sampling cup 7 is in sliding fit with the inner side wall of the sampling tube 3. The sampling cup 7 is pulled up by the lifting rod 5 and is in sliding fit with the inside of the sampling tube 3 under the elastic force of the pressure spring 6, that is, the sampling cup 7 is located inside the sampling tube 3 in a normal state. Meanwhile, as an optimization, the lower end opening of the sampling tube 3 is in threaded connection with a sealing cover 4, the lower end opening of the sampling tube 3 is sealed by the sealing cover 4, and the sampling cup 7 is sealed inside the sampling tube 3. And, sealed lid 4 can also be used as the base, has saved the test-tube rack among the prior art to put this device on the checkout stand immediately, prevent that the shit sample from pouring out sampling cup 7, kill many birds with one stone.

The specific implementation mode is as follows: in the initial state of the sampling device of the present invention, as shown in fig. 1 and 2, the sampling cup 7 is pulled up by the lift rod 5 and is shrunk and slidably fitted into the sampling tube 3. When the sampling device is used specifically, a patient presses the handle 1 downwards to prompt the sampling cup 7 to move downwards to the lower part of the sampling tube 3. Then the sampling cup 7 is used for containing excrement, after the excrement is contained in the sampling cup 7, the patient slowly loosens the handle 1, the sampling cup 7 moves upwards and enters the sampling tube 3 again, and finally the sealing cover is connected. When a doctor samples excrement, the sealing cover is taken down firstly, and then the handle 1 is pressed downwards. Therefore, the excrement can not be exposed in the air, and the potential safety hazard to the environment caused by the excrement is eliminated.

As another optimization, the bottom of the sampling cup 7 is hemispherical in the scheme. Simultaneously, in order to prevent the smell of shit and the clearance leakage in the bacterium passes through lifter 5 and sampling tube 3 support, the cover is equipped with rubber telescope tube 2 on lifter 5, the one end and the 1 fixed connection of handle of rubber telescope tube 2, the other end and 3 fixed connection of sampling tube. Utilize the rubber sleeve to realize sealing completely to the pressure spring 6 of lifter 5, and then prevent that the finger from contacting lifter 5, prevent simultaneously that the shit smell from leaking.

In the present case, the sampling tube 3 can be made of hard plastic material, and can be made of transparent plastic. Meanwhile, the sampling cup 7 is also made of transparent plastic. The shaft of sampling tube 3 is marked with scale 31 along the axial direction. Thus, the shape of the excrement in the sampling cup 7 can be directly observed through the sampling tube 3, and whether the sampling quantity of the excrement meets the inspection requirement or not can be known by using the scale 31. It should be noted that, although the sampling device seems to be complicated in structure, more expensive in cost than the conventional disposable open plastic test tube, and seems to be limited in application range, the sampling device is mainly used for some suspected and confirmed patients with infectious diseases, so that the possibility of virus transmission can be reduced to the maximum extent, the public health and safety can be ensured, and the sampling device is of great significance in preventing medical staff from being accidentally infected.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
