Background technique

With the improvement of social living standards, medical and health care is receiving more and more attention. Among them, "stool routine test" is one of the "three routine" medical clinical test items, and it is a routine test item that must be taken for hospitalized patients. Due to the lack of appropriate technical means, such as easy-to-operate stool sample test containers, both doctors and patients usually give up or refuse the test due to troublesome stool sampling, pungent odor, and inconvenient sampling. What's more, a small number of medical institutions have given up the inspection project due to fear of germ infection or secondary pollution.

To meet this demand, CN200520065425.7 Utility Model Patent Specification discloses a disposable stool test container 1 for medical tests. As shown in Figure 1, structurally, it comprises the following several parts, the bottle base 101, the bottle body 102 that is arranged on the top of the bottle base 101, the bottle cap 103 that is arranged on the bottle body 102 top, passes through the bottle cap 103 and extends into The handle 104 in the inner cavity of the bottle body 102 is arranged on the elastic gasket 105 between the handle 104 and the bottle cap 103 .

Detailed ways

Referring to Figures 2, 3, 4, 5 and 6, the stool test container of the present invention and related components thereof are shown. In the figure, the placement state of the stool test container after accommodating the sample is taken as the reference reference direction of the drawing.

The stool test container 2 is mainly composed of the following parts: a test chamber 201 , a sample storage chamber 202 , an end cover 203 and a sampling rod 204 .

Wherein, the inspection chamber 201 is a generally cylindrical hollow cavity formed by surrounding with an outer wall. The sample storage chamber 202 is also a substantially cylindrical hollow cavity surrounded by an outer wall. The sample storage chamber 202 is near the first communication port 206 described below, that is, on its bottom wall 214, along the vertical direction of the sample storage chamber 202, a funnel-shaped cone with a gradually shrinking radial dimension is provided from top to bottom. Shaped discharge port 210. The tapered discharge port 210 communicates with the first communication port 206 . When the stool test container 2 is in the transportation or storage state, the conical discharge port 210 is usually closed with the third elastic rubber plug 213 , so that the conical discharge port 210 and the first communication port 206 are in an isolated state. In order to improve the operability of the production process, in this embodiment, the outer wall surrounding the inspection chamber 201 consists of a part of the base 205 vertically upward and a part of the outer wall surrounding the inspection chamber 201 vertically downward, that is, these two parts The outer walls jointly form the cylindrical hollow cavity of the inspection room 201 after they are docked. For the convenience of installation, the cylindrical cavities of the inspection chamber 201 and the sample storage chamber 202 are kept in a coaxial state. In order to ensure that the inspection chamber 201 is in an overall airtight state except for its predetermined opening, the base 205 and the outer wall of the inspection chamber 201 connected to it can be connected as a whole by bonding or ultrasonic welding. Of course, a simple mechanical method can also be considered. Contact seal form. In order to facilitate the operator to observe the state of the samples inside and operate in an observable state, transparent plastics are usually used as raw materials to prepare the outer walls of the inspection chamber 201 and the sample storage chamber 202 .

The test chamber 201 is provided with a first communication port 206 (see FIG. 5 ) connected to the sample storage chamber 202 at its vertically upper part. The specific position of the first communication port 206 is at the vertically downward part of the outer wall of the sample storage chamber 202 , that is, on the bottom wall 214 of the sample storage chamber 202 . The test room 201 is provided with a second communication port 207 at its vertically lower part to communicate with the external environment, such as the atmosphere. The second communication port 207 is specifically located at a vertically downward portion of the base 205 . A filter 208 is provided at a portion between the first communication port 206 and the second communication port 207 inside the inspection chamber 201 . The filter screen 208 separates the first communication port 206 from the second communication port 207, so that the samples entering the test chamber 201 through the first communication port 206, especially fluid samples, must be filtered by the filter screen 208 before reaching the second communication port. It communicates with the port 207 . On the chamber wall of the inspection chamber 201 between the first communication port 206 and the filter screen 208, a first through hole 211 for communicating with the external environment such as the atmosphere is opened. The first through hole 211 is closed by a first elastic rubber plug such as silicon rubber 215 or the like. As a channel for injecting additional reagents inside, it is also possible to consider opening an auxiliary through hole 211 on the wall of the sample storage chamber 202 (see the auxiliary through hole 211 shown in dotted line in Figure 3), and close it with a corresponding rubber plug. Above the filter screen 208 in its position in the test room 201, a stool test paper (not shown) can be further set or placed.

The end cap 203 is detachably sealed on the vertically upward opening 209 of the sample storage chamber 202 , and is kept in a sealed state with the outer wall of the opening 209 . The joint form between the end cap 203 and the outer wall of the opening 209 can adopt the connection in the form of the thread 212 provided on the outer wall of the opening 209 in this embodiment, or a simple mechanical contact sealing form can be considered, such as connecting the end cap 203 with the opening. A snap fit is formed between the ports 209 . A second through hole 216 communicating with the external environment is opened on the end cover 203 . The second through hole 216 is closed by a second elastic rubber plug such as silicon rubber 217 .

The first end 219 of the sampling rod 204 facing away from the tapered discharge opening 210 of the sample storage chamber passes through the third through hole 218 opened on the end cover 203 to the outside of the sample storage chamber 202 in a slidable manner. The portion of the first end 219 of the sampling rod outside the end cap 203 is provided with a concave ring 221 shrinking along the diameter direction of the sampling rod 204 . A card 222 capable of preventing the sampling rod 204 from sliding toward the sample storage chamber 202 in the third through hole 218 of the end cap is snapped on the concave ring 221 in a detachable manner. A convex ring 223 expanding along the diameter direction of the sampling rod 204 is provided between the end of the first end 219 of the sampling rod and the concave ring 221 . The sampling rod 204 faces the second end 220 of the tapered discharge port 210 of the sample storage chamber, and its position is aligned with the third elastic rubber plug 213 . When the card 222 is removed from the concave ring 221, and the sampling rod 204 slides into the sample storage chamber 202 under the action of external thrust, the second end 220 of the sampling rod discharges the third elastic rubber plug 213 from the sample storage chamber in a conical shape. Push out from port 210 to test chamber 201. On the outer surface of the middle section of the sampling rod 204 corresponding to the position of the sample storage chamber 202 , there are stool sampling teeth 224 extending outward along the diameter direction of the sampling rod 204 .

When using the stool test container 2, unscrew the end cover 203, use the stool sampling tooth 224 in the middle of the sampling rod 204 to pick up the stool sample, put it into the sample storage chamber 202, remove the card 222 to insert the sampling rod 204 into the first communication port 206, and tighten it. end cap 203 . Immediately, a needle syringe is used to inject physiological saline through the first through hole 211 or the second through hole 216 to dilute the stool sample and make it flow onto the filter screen 208 . At this time, the additional test paper placed on the filter screen 208 can help the inspector to make a preliminary judgment. On the other hand, the filtrate leaking through the filter screen 208 is introduced into an external test tube through the second communication port 207, and stored for later use.
