A double-cover stool sampler

Abstract

The invention discloses a double-cover excrement sampling device. The double-cover excrement sampling device comprises a container, a sampling rod and a container cover, wherein the container cover comprises a front cover and a rear cover; the front cover is in threaded connection with the head part of the container; the rear cover is in threaded connection with the tail part of the container; a thread is arranged at one end of the sampling rod and a plurality of axial beads are arranged at the other end of the sampling rod; the other end of the sampling rod is connected with the end face with the thread of the rear cover; a sample discharging nozzle is arranged at the head part of the container. The container is divided into a container body and a connection part; the sectional area of the connection part is larger than that of the container body; the inner side of the connection part is provided with a thread for forming threaded connection of the rear cover and the tail part of the container; the connection part and the container body are in an integrally-connected structure; a sealing part is clamped at the connection part of the connection part and the container body; a through hole is formed in the middle of the sealing part. The device is simple in structure; sampling and sample discharging operation is convenient; quantitative sampling can be realized in a sampling process; the impermeability of preserving samples by the whole device is good and the device is sanitary and has no bad smell.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a sampling device, in particular to a stool sampler with double covers. Background technique [0002] Clinical stool test is one of the routine testing methods in medical units. For example, occult blood in feces cannot be directly detected by the naked eye, so most patients with early digestive tract malignancies cannot be detected in time and treated early, thus delaying the best time for treatment. At this time, a stool test is required. [0003] Most of the currently used stool samplers are a container, and a sampling spoon or a sampling stick is arranged in the container. There are many defects in this type of sampler: such as poor sealing, large pollution, and not hygienic enough; another example is that it is easy to take too many samples during testing, and it is inconvenient to operate. [0004] For example, Chinese Patent Publication No.: CN201935818U, in the patent ...
