Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to an automatic capping device for a stool sampling tube. Background Art

[0002] Stool examination is one of the three routine medical examinations (blood, urine, and feces). Routine stool examination can understand whether there are bacterial, viral, and parasitic infections in the digestive tract, detect gastroenteritis and liver diseases at an early stage, and can also be used as a diagnostic screening for digestive tract tumors. Routine stool tests include examining whether there are red blood cells and white blood cells, bacterial sensitivity tests, occult blood tests (OB), and checking for eggs in the feces. Routine stool examination is a necessary examination item for judging the health status of the human body.

[0003] As one of the "three routines" of physical examination items, the purpose of routine stool examination is: (1) to understand whether there are pathological components such as inflammatory products, blood, parasite eggs, or worm bodies in the feces; (2) to judge the functional status of the stomach, intestines, pancreas, and liver according to the properties and composition of the feces; (3) to use fecal occult blood examination as a screening test for the diagnosis of digestive tract malignancies; (4) to smear and perform Gram staining or culture to check whether there are pathogenic bacteria or dysbacteriosis in the feces to prevent and treat intestinal infections.

[0004] In the prior art, the commonly used tool for collecting stool is a disposable plastic tube. The cotton swab for sampling is arranged at the bottom of the sealing cap. When in use, only need to unscrew the sealing cap to take a sample, and then tighten the sealing cap after taking the sample to complete the sampling. This design can not only ensure that the sampling cotton swab is not easy to fall off, but also prevent the spread of fecal odor. However, before the inspection personnel conduct the inspection, they need to spend a lot of time unscrewing the sealing caps of the sampling tubes one by one, which not only increases the workload of the inspection personnel, but also results in low inspection efficiency. Summary of the Utility Model

[0005] The utility model aims to provide an automatic capping device for a stool sampling tube to solve the technical problem that the sealing cap of the stool sampling tube in the prior art cannot be automatically capped.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] An automatic capping device for a stool sampling tube, comprising a box body and a box cover. One side of the top of the box body is hinged to the box cover, and the other side of the top of the box body is clamped to the box cover. Inside the box body, there is a motor and a support seat. The motor is fixedly arranged on the bottom wall of the box body, and the output shaft of the motor extends upward and is fixedly connected to the support seat. Along the circumference of the top of the support seat, there are several equally spaced grooves. There are at least two groups of the grooves. Inside the grooves, there are sampling tubes. The sampling tube includes a tube body and a sealing cover threadedly connected to the top of the tube body. At both ends of the groove, there are symmetrically arranged limiting grooves extending outward. On both sides of the tube body, there are ridges adapted to the limiting grooves. On the circumferential outer wall of the sealing cover, there are teeth, and on the inner top wall of the box cover, there is an annular rack meshing with the teeth.

[0008] Principle of the technical solution: Open the box cover, place the sampling tube to be tested in the groove of the support seat, cover the box cover, start the motor, and the rotating motor drives the support seat to rotate. Due to the setting of the limiting groove, with the cooperation of the annular rack, the tube body of the sampling tube in the groove cannot rotate, and the sealing cover rotates reversely relative to the tube body, achieving the purpose of automatically unscrewing the sealing cover.

[0009] Further, at the bottom of the support seat, there is a chassis. The chassis is fixedly connected to the output shaft of the motor. The chassis is detachably connected to the support seat. Along the circumference of the bottom of the chassis, there are several equally spaced columns. On the inner bottom wall of the box body, there is an annular disc. On the top of the annular disc, there is an annular groove for the columns to slide.

[0010] Through the cooperative setting of the columns and the annular groove, the support seat can rotate stably and is not prone to shaking.

[0011] Further, at the bottom of the column, there are balls.

[0012] The setting of the balls makes the rotation of the support seat smoother.

[0013] Further, on the inner top wall of the sealing cover, there is a sampling cotton swab. The bottom of the tube body is conical. On the inner walls of the groove and the limiting groove, there is a protective layer.

[0014] The conical tube body facilitates the tester to quickly place the sampling tube in the groove, and the protective layer can prevent the outer wall of the sampling tube from being scratched by the inner wall of the groove, resulting in the destruction of the stool sample information.

[0015] Further, along the circumference of the bottom of the box body, there are 4 equally spaced support columns. At the bottom of the support columns, there is an anti-slip layer.

[0016] The anti-slip layer can prevent the equipment from shifting during operation.

[0017] In summary, the utility model has the following beneficial effects:

[0018] This device can achieve the purpose of automatically unscrewing the lid of the stool sampling tube, and can simultaneously unscrew the lids of multiple sampling tubes to be inspected, reducing the lid-unscrewing time of the inspectors, reducing the workload of the inspectors, and improving the work efficiency of the inspectors; secondly, directly installing the support seat with the sampling tube on the chassis can reduce the time for secondary transfer of the sampling tube and improve the work efficiency of the inspectors.

[0024] The present utility model will be further described in detail below in conjunction with the drawings and embodiments:

[0025] As Figures 1 to 3 shown, an automatic lid-unscrewing device for a stool sampling tube includes a box body 1 and a box cover 2. The rear side of the top of the box body 1 is hinged to the rear side of the box cover 2, and the front side of the top of the box body 1 is snap-connected to the front side of the box cover 2. Four support columns 19 with equal intervals are circumferentially arranged at the bottom of the box body 1, and an anti-slip layer 20 is provided at the bottom of the support columns 19.

[0026] Inside the box body 1, there are a motor 3, a chassis 21 and a support seat 4. The motor 3 is fixedly installed on the bottom wall of the box body 1. The output shaft of the motor 3 extends upward and is fixedly connected to the chassis 21. The chassis 21 is detachably connected to the support seat 4. The support seat 4 is fixedly connected to the output shaft of the motor 3 through the chassis 21. A number of equally spaced grooves 5 are provided along the circumference at the top of the support seat 4. There are at least two groups of grooves 5. A sampling tube 6 is arranged in the groove 5. The sampling tube 6 includes a tube body 7, a sealing cover 8 threadedly connected to the top of the tube body 7, and a sampling cotton swab 17 provided on the inner top wall of the sealing cover 8. Limiting grooves 9 extending outward are symmetrically provided at both ends of the groove 5. Each groove 5 is provided with four limiting grooves 9. The inner walls of the groove 5 and the limiting grooves 9 are provided with a protective layer 18. Convex strips 10 adapted to the limiting grooves 9 are provided on both sides of the middle of the tube body 7. Teeth 11 are provided circumferentially on the outer side wall of the sealing cover 8. An annular tooth strip 11 meshing with the teeth 11 is fixedly installed on the inner top wall of the box cover 2. The bottom of the tube body 7 is conical.

[0027] A number of equally spaced columns 13 are provided circumferentially at the bottom of the chassis 21. An annular disc 14 is fixedly installed on the inner bottom wall of the box body 1. An annular groove 15 for the columns 13 to slide is provided at the top of the annular disc 14. A ball 16 is provided at the bottom of the column 13.

[0028] Although in this example, only 2 groups of grooves 5 are provided and a total of 18 sampling tubes can be placed, in actual application, the number of groups of grooves provided, as well as the number of grooves in each group, can be designed correspondingly according to the quantity to be inspected in each batch and the specifications of the sampling tubes.
