Description

A stirring mechanism of an automatic stool analyzer

technical field

The invention relates to a medical device, in particular to a sealed stirring mechanism of an automatic stool analyzer capable of preventing cross-infection.

Background technique

In the field of clinical testing, routine blood tests, routine urine tests, and routine stool tests are referred to as the "three routine tests". The advent and use of automated instruments for blood and urine routine testing has promoted the modern technological content of the two routines and improved the quality and speed of testing. However, the whole process of routine feces inspection is still in the original state so far. From the collection of specimens to the inspection of specimen operations and the final disposal of specimen waste liquid, it has caused pollution to the environment and laboratories; in order to prevent the spread of infectious diseases, the use of The cotton swabs used to collect specimens and the items containing the specimens must undergo special treatment. The more links in the treatment, the higher the probability of contamination, and the inspection process is also very unhygienic; these have become medical and health units at all levels. A major bottleneck in improving inspection quality and speed.

At present, there are not many domestic and foreign researches on automatic stool detection instruments, and some detection instruments that have been used cannot completely solve the problem of cross-contamination and air pollution caused by the original normal inspection process. For example, the application number is 200910046366.1, and the name is the Chinese invention patent of the multifunctional specimen box. This specimen box is used with a set of detectors. A rotating interface is arranged on the shaft, and a sampling spoon is arranged under the rotating shaft. When in use, the operator opens the box cover, takes an appropriate amount of samples with a sampling spoon, closes the box cover tightly, and then puts it into the detector. The rotary joint in the detector is connected to the rotary interface to drive the sampling spoon to rotate to realize the stirring of the samples. However, the specimen box of this patent and the matching detector have the above-mentioned shortcomings. Since the rotating shaft of the specimen box needs to be connected to the rotary joint in the tester to rotate, one end of the rotating shaft is inserted into the specimen box during design. The other end is exposed on the box cover, which makes the specimen box not airtight, which is prone to cross-infection, which not only makes the instrument infected, but also requires special treatment or even discarding of the instrument, which increases the cost and also increases the cost. The operator is infected and affects the health of the operator.

Contents of the invention

The present invention mainly solves the technical problem that the general detector in the prior art cannot stir the specimen during the sealing process, which makes it easy to cause cross-contamination and air pollution, and provides a sealed automatic stool analyzer that prevents cross-infection Stirring mechanism.

The above-mentioned technical problems of the present invention are mainly solved by the following technical solutions: a stirring mechanism of an automatic stool analyzer, including a specimen box arranged in the analyzer, the specimen box is provided with a cover body, and the cover body is sealed and covered On the sample box, a sealed cavity is formed in the sample box, and a stirring rod is connected to the cover in rotation. The stirring rod extends into the cavity of the sample box. The analyzer is provided with a magnetic rotating part, and the sample box is located on the upper part of the magnetic rotating part. The specimen box of the present invention adopts a fully sealed structure, and the rotating body is driven to rotate through the magnetic rotating part located under the specimen box, and the rotating body drives the rotation of the stirring rod to realize the stirring of the feces specimen in the specimen box. Compared with the traditional structure that uses the rotating needle to drive the stirring rod to rotate and the sample box is not sealed, the present invention avoids the cross-infection caused by the unsealed test of the stool sample, so that the analyzer will not be discarded due to infection, which not only protects the analyzer , saving costs and protecting operators from infection.

As a preferred solution, the magnetic rotating part includes a motor and a magnet arranged at the front end of the rotating shaft of the motor, and the magnet is located below the specimen box. The rotation of the motor can drive the magnet to rotate. The magnet is located under the specimen box. Affected by the magnetic force, the rotating body in the specimen box will rotate accordingly, thereby driving the stirring rod to rotate.

As a preferred solution, a rotating seat is provided on the inner wall of the cover, the inner cavity of the rotating seat is large and the opening is small, the rear end of the stirring rod is a rotating head matching the size of the inner cavity of the rotating seat, and the stirring rod rotates The head is installed in the swivel seat. The rotating head of the stirring rod and the rotating seat jointly constitute a rotating mechanism, and the rotating head is clamped on the inner cavity of the rotating seat.

As a preferred solution, the front end of the stirring rod is a stirring head, and several burrs are arranged on the outer wall of the stirring head. The stirring head can stir the stool specimen well.

As a preferred solution, the burrs are tilted upwards. The burr structure makes the stirring effect better.

As a preferred solution, several through holes are provided on the stirring head, a groove is provided on the front end of the stirring head, and the rotating body is installed in the groove. When stirring, the stirring material can pass through the through hole, which makes the stirring more uniform and the stirring effect better, and also plays the role of collecting stool samples.

As a preferred solution, the rotating body is a magnet or an iron sheet. The rotating body can be affected by the magnetic force of the magnetic rotating part set in the analyzer, so that when the magnetic rotating part rotates, it drives the rotating body to rotate through the magnetic force, so as to drive the stirring rod to rotate in the sealed state of the specimen box.

As a preferred solution, an opening is provided at the position where the cover body is located at the bottom of the rotating seat, a sealing cover is arranged on the opening, a water inlet tank is formed in a hollow at the rear end of the stirring rod, and the opening of the water inlet tank communicates with the inner cavity of the rotating seat. A water outlet hole is arranged on the bottom end wall of the water inlet tank, and the water outlet hole communicates the water inlet tank with the inner cavity of the specimen box. Before stirring, the specimen box can be filled with water. First, pull out the sealing cover and inject water. The water enters the inner cavity of the rotating base and enters the water inlet tank, and finally flows into the inner cavity of the specimen box through the water outlet hole. The sealing cover is closed, so that the cavity of the specimen box re-forms a sealed structure.

As a preferred solution, a retaining ring is provided on the outer wall near the rotating head at the rear end of the stirring rod. The retaining ring restricts the retraction of the stirring rod to the rotating seat, and also makes the stirring rod rotate more smoothly.

Therefore, the advantage of the present invention is that: the specimen box adopts a fully sealed structure, and the rotating body is driven to rotate through the magnetic rotating part located below the specimen box, and the rotating body drives the rotation of the stirring rod, thereby realizing the stirring of the stool specimen in the specimen box. The invention avoids the cross-infection caused by unsealed test of the stool specimen, so that the analyzer will not be discarded due to infection, which not only protects the analyzer, saves costs, but also protects operators from infection.
