Description
Technical field
The present invention relates to a kind of medical instrument more particularly to a kind of loose stools sampling rods.
Background technique
In order to which the stool to patient is chemically examined, needs the stool that patient is discharged to take one piece to be placed in Bedpan, send to change
Room is tested to be chemically examined.For shaping preferable stool, one piece of sample can be dug using sample spoon.But for loose stools, sample spoon
The major part taken is watery soup, is not able to satisfy the sample size that chemical examination requires.
It is proposed that some samplers for loose stools, such as CN205317500U disclose a kind of stool mark in the prior art
This collecting cassette, collection head therein forms spoon shape, and multiple holes are formed on collection head, in this manner it is possible to watery soup is missed,
Only retain solid stool.
It is carried out generally in closestool when patient's defecation, water is itself had in closestool, along with the watery soup of loose stools itself, so that
Object is divided into two layers in closestool, and upper layer is liquid, and lower layer is the solid-state stool of precipitating；It, must when pulling solid-like stool out from lower layer
When by upper layer need be that liquid could take out, and pass through liquid level, the excrement sample in spoon is easy to be diluted to again
In liquid, the solid-state excrement sample for adopting sufficient amount is repeatedly possible to repeatedly.
Summary of the invention
In view of the above problems, the present invention is directed to propose a kind of loose stools sampling rod, the solid-state stool mark that can be got from lower layer
This and by that will not be swept away or be diluted when the liquid of upside during taking-up, therefore can once-through operation just get it is enough
Solid-state excrement sample.

Specific embodiment
In the following, loose stools sampling rod of the invention is described in detail in conjunction with attached drawing.
The loose stools sampling rod of the application comprising: barrel member 10 and spoon component 20.
The first hollow portion 15a and the second hollow portion 15b is formed in barrel member 10；First hollow portion 15a and the second hollow portion
15b connection, and it is all formed as cylinder；Diameter of the diameter of first hollow portion 15a less than the second hollow portion 15b；First is hollow
The first end of portion 15a is closed；The second end of first hollow portion 15a is connect with the first end of the second hollow portion 15b；Second hollow portion
The second end of 15b is the first opening；Barrel member 10 is formed with the second opening 12 in its first end, and the second opening 12 and first is hollow
Portion 15a connection.
Spoon component 20 includes spoon head, spoon bar 24 and handle 25；Spoon head is formed in the first end of spoon bar；Handle 25 is formed in spoon
The second end of bar 24 is formed as flat shape, convenient for users to holding and rotating spoon component 20；Spoon head includes bottom plate 21, front end
Plate and pedestal 23；Bottom plate 21 is the curved of circular arc, and front end-plate is located at the first end of bottom plate 21, and pedestal 23 is located at the of bottom plate 21
Thus two ends constitute the first dented space for accommodating loose stools sample.
Spoon component 20 is inserted in barrel member 10, and spoon head is located in the first hollow portion 15a and can be in the first hollow portion 15a
Middle rotation, the outer peripheral surface of pedestal 23 are tightly attached on the inner peripheral surface of the first hollow portion 15a；When stand-by state, the covering of bottom plate 23 or gear
Firmly the second opening 12；When collecting sample, the first dented space face second opening 12；Handle 25 is opened from the first of the second hollow portion
Mouth extends to the outside of barrel member 10.
The surface of barrel member 10 and spoon component 20 is coated with Teflon, can be sticked to loose stools sampling rod in this way to avoid stool
Surface.
The first end of barrel member 10 is formed as the tip 11 of taper, facilitates insertion into the solid-state stool of the bottom of loose stools.
The second end of barrel member 10 is formed with the second dented space 14；12 difference position of second dented space 14 and the second opening
In the two opposite sides of barrel member 10.
It is formed with extension plate 16 in second dented space 14, to partly cover the second dented space 14.Second recess is empty
Between 14 for accepting from the second opening into the liquid inside barrel member 10, near liquid runs down cylinder internal flow second is open
When, it falls into the second dented space 14, makes the hand or clothes of medical staff dirty from outflow.
Along the periphery of barrel member 10, it is formed with baffle 13 in the second end of barrel member 10, between baffle 13 and the first opening
It is formed with preset distance.13 purpose of baffle is to prevent the liquid being stained on the outside of barrel member from flowing to medical staff on hand.
Silica gel strip 22 is fixed on the edge of first dented space, the first hollow portion 15a's be close in the edge of silica gel strip 22
Inner peripheral surface enters inside barrel member in this way in spare and sampling process so that liquid feed in stool is few.
In stand-by state, spoon component is inserted in barrel member, the second opening of bottom plate covering, so that the liquid in stool is not
It can enter in barrel member or only considerably less liquid enter in barrel member.Then the first end of barrel member is inserted into loose stools
Lower part, until insertion solid-state stool deposition part in；Next, rotating handle, so that the first dented space of spoon head is just
It is open to second, in this way, solid loose stools flows into the first dented space of spoon head via the second opening；After predetermined time, turn
Fixed handle, so that bottom plate covers the second opening again, so that the solid-state stool being contained in spoon head is isolated from the outside out, in this way,
When just extracting loose stools sampling rod out, by stool upside liquid part when, the stool in spoon head will not be diluted, and will not be rushed
Out, the sample of the solid-state stool of sufficient amount is remained.
