Detailed Description

The invention will be described in detail with reference to the accompanying drawings.

The application discloses thin just sampling rod, it includes: a barrel member 10 and a spoon member 20.

A first hollow portion 15a and a second hollow portion 15b are formed in the barrel member 10; the first hollow portion 15a and the second hollow portion 15b communicate, and are each formed in a cylindrical shape; the diameter of the first hollow portion 15a is smaller than that of the second hollow portion 15 b; the first end of the first hollow portion 15a is closed; the second end of the first hollow portion 15a is connected to the first end of the second hollow portion 15 b; the second end of the second hollow portion 15b is a first opening; the barrel member 10 is formed with a second opening 12 at a first end thereof, the second opening 12 communicating with the first hollow portion 15 a.

The spoon member 20 comprises a spoon head, a spoon shaft 24 and a handle 25; the spoon head is formed at the first end of the spoon rod; a handle 25 formed at the second end of the spoon shaft 24 and formed in a flat shape to facilitate the user's holding and rotating the spoon member 20; the spoon head comprises a bottom plate 21, a front end plate and a base 23; the bottom plate 21 is curved in a circular arc shape, the front end plate is located at a first end of the bottom plate 21, and the base 23 is located at a second end of the bottom plate 21, thereby forming a first concave space for accommodating a stool sample.

The spoon member 20 is inserted into the barrel member 10, the spoon head is positioned in the first hollow part 15a and can rotate in the first hollow part 15a, and the outer peripheral surface of the base 23 is tightly attached to the inner peripheral surface of the first hollow part 15 a; in the standby state, the bottom plate 23 covers or blocks the second opening 12; when the sample is collected, the first concave space is opposite to the second opening 12; the handle 25 extends from the first opening of the second hollow portion to the outside of the barrel member 10.

The surfaces of the barrel member 10 and the spoon member 20 are coated with teflon so that the adhesion of stool to the surface of the thin stool sampling rod can be prevented.

The first end of the barrel member 10 is formed as a tapered tip 11 to facilitate insertion into the solid stool at the bottom of a loose stool.

The second end of the barrel member 10 is formed with a second recessed space 14; the second recessed space 14 and the second opening 12 are located on opposite sides of the barrel member 10, respectively.

An extension plate 16 is formed on the second concave space 14 to partially cover the second concave space 14. The second recessed space 14 is used for receiving the liquid entering the inside of the barrel component 10 from the second opening, and the liquid falls into the second recessed space 14 when flowing along the inside of the barrel and near the second opening, so that the liquid is prevented from flowing out to pollute hands or clothes of medical staff.

A flap 13 is formed at the second end of the barrel member 10 along the outer periphery of the barrel member 10, with a predetermined distance being formed between the flap 13 and the first opening. The purpose of the flap 13 is to prevent the liquid adhering to the outside of the barrel component from flowing to the hands of the medical professional.

A silicone strip 22 is fixed on the edge of the first concave space, and the edge of the silicone strip 22 is tightly attached to the inner circumferential surface of the first hollow part 15a, so that liquid in stool enters the barrel component as little as possible in the standby and sampling processes.

In the ready-to-use state, the scoop member is inserted into the barrel member and the bottom plate covers the second opening such that no or only very little liquid in the stool enters the barrel member. Then inserting the first end of the barrel member into the lower portion of the loose stool until it is inserted into the portion where the solid stool settles; then, the handle is rotated to enable the first concave space of the spoon head to face the second opening, so that solid dilute excrement flows into the first concave space of the spoon head through the second opening; after the predetermined time, the handle is rotated for the bottom plate covers the second opening once more, makes the solid-state excrement that holds in the spoon head keep apart with the outside, and like this, when just taking out thin just sampling rod, when the liquid part of excrement upside, the excrement in the spoon head can not diluted, also can not washed out, has kept the sample of the solid-state excrement of sufficient volume.
