Background
In the daily care of long-term bedridden patients, some critically ill patients can have serious continuous diarrhea due to the disease conditions, medicines and the like, the patients have no self-care ability, even are unconscious and bedridden, and the continuous excrement can be cleaned only by nursing staff at regular time. The excrement of a patient lying in bed for a long time or suffering from severe diarrhea is mostly in a thin water sample and contains more bacteria, the excrement overflows to cause serious pollution and bring great difficulty to nursing work, and inflammation such as red swelling, pain, eczema and the like can be caused to cause incontinence-related dermatitis after the perianal area and the hip of the patient are exposed to the excrement for a long time or repeatedly. Therefore, the excrement collection and treatment of the patients with incontinence and diarrhea are needed, and the samples of the patients are also needed to be subjected to routine, occult blood and culture plus drug sensitivity tests. The current defecation device is unreasonable in design, the incontinence nursing problem is often solved by replacing traditional methods such as diapers and bed sheets, and the traditional nursing method is difficult to leave qualified specimens, so that the examination result is inaccurate, and the diagnosis and treatment of patients are delayed. In view of the above problems, the present invention provides an excrement sampler to solve the above proposed problems.
For example, the prior art, such as chinese patent publication No. CN208974777U, discloses a device for collecting feces of a bedridden incontinent patient, which comprises a rectal insertion tube made of silicone for being inserted into the rectum of the patient via the anus, a connection hose, and a collection tube, wherein a first end of the rectal insertion tube is formed with a rim extending obliquely outward at its periphery, a first end of the connection hose is connected to a second end of the rectal insertion tube, the collection tube is used for accommodating the loose stool discharged from the patient, a second end of the connection hose is connected to a first port at an upper end of the collection tube, and a second port is formed at an upper end of the collection tube for discharging the air in the collection tube to the outside. By inserting the rectal cannula into the rectum, the loose stool is discharged through the rectal cannula without contacting the anal orifice, and the discharged loose stool enters the collection canister. The utility model discloses a beneficial technological effect be: the utility model is inserted into the rectum, so that loose stool is discharged from the rectum through the rectum cannula and is not contacted with the anus; the discharged thin liquid enters the collecting cylinder. The whistle is arranged on the second port of the collecting cylinder, and when the discharge exists, the whistle can make a sound to remind nursing staff. However, the utility model still has the following technical disadvantages: the utility model discloses a can not take the experiment sample quantitatively, also can not carry out the segmentation to patient exhaust stool and urine appearance sealed to select the stool and urine appearance of needs to experiment.

When the negative pressure machine 31 is started, the negative pressure machine 31 will form a negative pressure environment in the collection cavity 2, and the excrement can be conveniently introduced into the collection cavity 2, because the negative pressure pipe 30 is communicated with the collection cavity 2.
According to a preferred embodiment, the collection chamber 2 is a glass bottle, and the surface of the collection chamber 2 is provided with a first partition valve 12 and a second partition valve 13 at any at least two different positions. By arranging the first partition valve 12 and the second partition valve 13, the spatial region in the collection chamber 2 can be divided into a first collection chamber 14, a second collection chamber 15 and a third collection chamber 16 from bottom to top, so that the stool sample discharged by the patient can be sealed in a segmented manner. The outer side surface of the collection chamber 2 is also provided with graduation marks. Preferably, the collection chamber 2 is transparent in order to facilitate the observation of the patient's stool samples by the medical staff.
According to another preferred embodiment, most of the structure of this embodiment is the same as that of the above embodiment, except that: the collecting cavity 2 is a flexible film, and at least two random different positions on the surface of the collecting cavity 2 are provided with knots in a bonding mode. By tying the knots, two knots can divide the spatial area inside the collecting chamber 2 into a first collecting chamber 14, a second collecting chamber 15 and a third collecting chamber 16.
According to a preferred embodiment, the collecting chamber 2 is provided with an external interface 17 corresponding to the outer side surface of the second collecting chamber 15, and the external interface 17 is provided with a flow stop switch 18 for controlling the outflow of the excreta from the second collecting chamber 15.
