Description

Technical Field

[0001] The utility model relates to the technical field of clinical feces collection, in particular to a clinical feces collection device. Background Art

[0002] In the current clinical examination of stool samples, a common method is to give a simple stool cup to the patient to collect the stool by himself, which specifically includes a cup body with a lid and a collection spoon inside the cup body.

[0003] For patients, the collection process is somewhat difficult. Some sticky and compact feces cannot be collected well with a spoon alone, and repeated stirring can easily lead to fecal contamination. The amount of feces collected cannot be well controlled, and the depth of the collected feces is limited to the surface.

[0004] For laboratory physicians and clinical researchers, additional instruments are required to extract feces from the spoon, which is inefficient.

[0005] Therefore, a clinical stool collection device is proposed to solve the above problems. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a clinical stool collection device, which has the advantages of simplifying the collection and extraction methods and being able to collect stool of different depths, thereby solving the problem that the existing stool cup collection and extraction methods are relatively troublesome.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a clinical stool collection device, comprising an outer holding rod, a collection shovel is fixed to the bottom surface of the outer holding rod, the collection shovel is semi-cylindrical and has a crescent-shaped cross section, and an inner push scoop that can move up and down is provided inside the collection shovel;

[0008] The inner push scoop comprises a scoop rod and a collecting tube connected to the end of the scoop rod, the collecting tube is cylindrical, and the outer edge of the collecting tube fits with the collecting shovel.

[0009] Furthermore, a sliding block is fixed on the upper part of the inner pushing spoon, a sliding groove for the sliding block to move up and down is arranged in the outer holding rod, and a pushing block is fixed on the sliding block.

[0010] Furthermore, the contact surface of the pushing block is wavy.

[0011] Furthermore, the long diameter of the bottom of the collection shovel is adapted to the inner diameter of the cryopreservation tube.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] The clinical stool collection device has a semi-cylindrical collection shovel with a crescent-shaped cross section. After the stool is inserted, the stool contact surface provides a shear resistance no less than the weight of the stool, so that the stool in the shovel does not fall off, thereby achieving quantitative and shaped full-layer collection of stool.

[0014] The push block drives the inner push scoop to move downward, so that the feces can be easily pushed out of the collection shovel to collect the feces. The contact surface of the push block is wavy, so that the thumb of the operator does not slip when contacting the push block during operation.

[0015] After collecting feces with the collection shovel, in order to facilitate the scientific research packaging of feces samples, the long diameter of the shovel bottom of the collection shovel is adapted to the inner diameter of the general cryopreservation tube, making it slightly smaller than the inner diameter of the cryopreservation tube. The feces can be directly pushed into the tube through the built-in push spoon, realizing the one-step packaging of the sample;

[0016] The collection shovel can be used to collect normal or dry and hard feces, and the collection tube at the end of the inner push spoon can also collect watery feces, making it well applicable to the collection of feces of different properties (loose feces, normal feces, dry and hard feces).

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 A clinical stool collection device in this embodiment includes an outer holding rod 1, and a collection shovel 2 is fixed to the bottom surface of the outer holding rod 1. The collection shovel 2 is semi-cylindrical and has a crescent-shaped cross-section. After the stool is inserted, the stool contact surface provides a shear resistance not less than the weight of the stool, so that the stool in the shovel does not fall off, thereby realizing quantitative and shaped full-layer collection of the stool.

[0023] The collecting shovel 2 is provided with an inner pushing scoop 3 which can move up and down, a slider 4 is fixed on the upper part of the inner pushing scoop 3, a slide groove 5 for the slider 4 to move up and down is provided in the outer holding rod 1, a pushing block 6 is fixed on the slider 4, the operator presses the pushing block 6 with the thumb and moves the pushing block 6 up and down, so that the slider 4 moves up and down in the slide groove 5, thereby driving the inner pushing scoop 3 to move up and down in the collecting shovel 2, which can conveniently push feces out of the collecting shovel 2, and the contact surface of the pushing block 6 is wavy, so that the operator's thumb is not easy to slip when contacting the pushing block 6 during operation, thereby enhancing practicality.

[0024] After the feces are collected by the collecting shovel 2, in order to facilitate the scientific research packaging and processing of the feces samples, the long diameter of the shovel bottom of the collecting shovel 2 is adapted to the inner diameter of a general freezing tube, making it slightly smaller than the inner diameter of the freezing tube. The feces can be directly pushed into the tube through the built-in inner push spoon 3, realizing the one-step packaging of the sample.

[0025] Since feces have different properties, such as loose feces, normal feces, and dry and hard feces, the collection shovel 2 can be used to collect normal or dry and hard feces, and the inner push spoon 3 can also be used to collect loose and watery feces. Figure 3 As shown, the inner push spoon 3 includes a spoon rod 31 and a collecting tube 32 connected to the end of the spoon rod 31. The collecting tube 32 is cylindrical. The spoon rod 31 can drive the collecting tube 32 to separate from the collecting shovel 2 and collect the thin water sample feces.

[0026] The outer edge of the collecting tube 32 fits with the collecting shovel 2. After the feces are collected, the pushing block 6 is moved downward, and the collecting tube 32 can be driven downward by the inner pushing scoop 3 to push out all the feces in the collecting shovel 2.
