DETAILED DESCRIPTION

[0038] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the following combines the drawings and embodiments, and further detailedly explains the utility model. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model. In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0039] For example, Figures 1-6As shown, the utility model embodiment provides a kind of multi-purpose feces quantitative sampler, comprising: sampling bottle 1 and sampling unit 2.

[0040] The sampling bottle 1 includes bottle body 101, bottle cap 102 and fixed clamping piece 103. The bottle cap 102 is arranged on the bottle mouth of the bottle body 101, and the two are connected by threads, with a round hole in between, which connects the inside of the bottle body 101 with the outside space. The fixed clamping piece 103 is arranged at the bottom outside the bottle body 101, which is a platform structure, and the cross section of the platform is a rounded rectangle.

[0041] The sampling unit 2 includes a sampling head 201, which is connected to the bottle cap 102 through a connecting pipe 202. The connecting pipe 202 is a hollow pipe, one end of which is connected to the round hole on the bottle cap 102 and is arranged on one side of the bottle cap 102 close to the bottle body 101. The sampling head 201 is cylindrical, with a round hole at the back end connected to the other end of the connecting pipe 202, and the other end is open, with an inclined notch at the opening.

[0042] The sampling head 201 is provided with a push plate 204, which has the same shape as the inner cross section of the sampling head 201 and moves in the sampling head 201. The push plate 204 is also provided with a push-pull rod 203 close to one end of the connecting pipe 202, which is arranged in the connecting pipe 202 and slides axially to push the push plate 204. The other end of the push-pull rod 203 protrudes from the round hole on the bottle cap 102, and the protruding end is provided with a push-pull head, which is a circular sheet structure, and the connection between the push-pull head and the push plate 204 is a tapered block. The length of the push-pull rod 203 is the length from the front end of the sampling head 201 to the round hole of the bottle cap 102. When the push-pull rod 203 pushes the push plate 204 to the same level as the front end of the sampling head 201, the tapered block of the push-pull head is clamped in the round hole of the bottle cap 102, preventing the push-pull rod 203 from continuing to push the push plate 204, causing the push plate 204 to come out of the cavity of the sampling head 201. And after the push-pull rod 203 is pushed to the front end, there is a gap between the push-pull head and the bottle cap 102 due to the blocking of the tapered block, which facilitates the subsequent pulling of the push-pull rod 203.

[0043] The push plate 204 divides the cavity in the sampling head 201 into an inner cavity 205 and an outer cavity 206. The inner cavity 205 is close to the rear end of the sampling head 201, and the outer cavity 206 is close to the front end of the sampling head 201 and is connected with the outside. The push-pull rod 203 is provided with a first rubber plug 209 at the connection with the push plate 204 in the inner cavity 205. The first rubber plug 209 is fixed on the push-pull rod 203 and tightly fits between the push-pull rod 203 and the push plate 204, slides with the push plate 204 in the cavity of the sampling head 201, and ensures the sealing between the push plate 204 and the sampling head 201. The side of the first rubber plug 209 away from the push plate 204 is a concave tapered surface, which is thinnest at the central position close to the push-pull rod 203 and thickest at the position close to the inner wall of the sampling head 201.

[0044] The push plate 204 is provided with a suction nozzle 207 at the center of the front end. The suction nozzle 207 has a soft stool channel 208 along the central axis, which extends into the push-pull rod 203. The push-pull rod 203 is provided with a transversely penetrating circular channel at the connection with the first rubber plug 209 on the opposite side, which is connected with the soft stool channel 208 to make the inner cavity 205 communicate with the outside. The part of the push-pull rod 203 in the connecting pipe 202 is also provided with a second rubber plug 210, which is fixed on the push-pull rod 203 and moves axially in the connecting pipe 202 to make the inner cavity 205 sealed from the outside at the end close to the bottle cap 102.

[0045] Preferably, since the push plate 204 moves in the sampling head 201 along the axial direction, the space sizes of the inner cavity 205 and the outer cavity 206 actually change with the position of the push plate 204. And since the diameter of the sampling head 201 is larger than that of the connecting pipe 202, even if the distance between the first rubber plug 209 and the second rubber plug 210 does not change during the movement of the push plate 204, the space of the inner cavity 205 will also change.

[0046] The outer cavity 206 is used for quantitative sampling of soft stools. In use, the bottle cap 102 is removed from the bottle body 101 together with the sampling unit 2, the push-pull rod 203 is pushed to make the push plate 204 at the front end of the sampling head 201, the sampling head 201 is aligned with the soft stool to be sampled, the bottle cap 102 is pressed downward, and the sampling head 201 is completely inserted into the soft stool. At this time, the amount of soft stool taken is the same as the maximum space of the outer cavity 206, realizing directional sampling. Then the bottle cap 102 is put into the bottle body 101 together with the sampling unit 2, the bottle cap 102 is tightened, the push-pull rod 203 is pressed downward, and the soft stool in the sampling head 201 falls into the sampling bottle 1.

[0047] Preferably, during the sampling of soft stool, only one communication port of the suction nozzle 207 is in communication with the outside world due to the continuous compression of the space of the inner cavity 205. During the movement of the push plate 204 to the rear end of the sampling head 201, the gas in the inner cavity 205 is discharged from the suction nozzle 207, thereby generating resistance and preventing the soft stool from entering the suction nozzle 207 and affecting the amount of soft stool sampling.

[0048] The inner cavity 205 is used for quantitative sampling of thin stool. In use, the bottle cap 102 is removed from the bottle body 101 together with the sampling unit 2, the push-pull rod 203 is pulled to place the push plate 204 at the last end of the sampling head 201, the sampling head 201 is completely immersed in the thin stool to be sampled, the bottle cap 102 is held stationary, the push-pull rod 203 is pressed to move the push plate 204 to the front end of the sampling head 201, at this time, the amount of thin stool sampled is the same as the maximum space of the outer cavity 206, and directional sampling is achieved. Then the bottle cap 102 is placed in the bottle body 101 together with the sampling unit 2, the bottle cap 102 is tightened, and the push-pull rod 203 is pulled upward, so that the thin stool in the sampling head 201 is pressed out and falls into the sampling bottle 1.

[0049] Preferably, during the sampling of thin stool, only one communication port of the suction nozzle 207 is in communication with the outside world due to the continuous expansion of the space of the inner cavity 205. Under the action of air pressure, the thin stool is sucked into the inner cavity 205 from the suction nozzle 207 along the thin stool channel 208. During the movement of the push plate 204 to the front end of the sampling head 201, the thin stool in the outer cavity 206 is pushed out by the push plate 204, and the thin stool remaining on the inner wall of the sampling head 201 is simultaneously scraped off by the push plate 204, so that the thin stool is not left in the outer cavity 206 and affects the amount of thin stool sampling.

[0050] The storage box for storing the sampling device is also provided in combination with the multi-purpose quantitative stool sampling device according to the present application. The bottom of the storage box is provided with a sampling device placing plate, and a plurality of placing holes are uniformly arranged on the placing plate. The shape of the placing hole is the same as that of the fixing clamping piece 103. After sampling is completed, the sampling device is placed in the storage box and temporarily fixed to the placing hole by the fixing clamping piece 103, so that storage and transportation after sampling is completed are realized.

[0051] Those skilled in the art can easily understand that the above description is only a preferred embodiment of the present application and is not used to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
