Description

Disposable sealed body fluid indweller

Technical field

The present invention relates to medical devices, and more particularly to containers for containing secretions or excretions, particularly a disposable closed body fluid indweller.

Background technique

At present, most hospitals provide the person in charge with a paper cup containing secretions or excretions. The inspector extracts the sample from the paper cup containing the secretions or excretion of the subject, and then places the sample in the test tube. The dilution is added to the test tube and the diluted liquid is then detected.

The collection and dilution of traditional secretions or excretions has many drawbacks. If the excreta or secretions are exposed during the inspection, it is easy to cause contamination of the sample. Secondly, the inspector needs to extract the sample to the test tube and dilute it, and then inspect the diluted sample. The work steps are numerous and the work is intense; in addition, the pungent smell of exposed secretions and excretions can easily cause damage to the working environment and reduce the efficiency of doctors, nurses, and inspectors.

Summary of the invention

It is an object of the present invention to provide a disposable sealed body fluid indweller that is simple to operate and less susceptible to contamination.

The object of the invention is achieved in this way:

A disposable sealed body fluid indweller comprising a liquid storage tube and a dilution tube; the liquid storage tube is provided with a liquid storage chamber and an opening portion; the dilution tube is provided with a dilution chamber; the liquid storage tube and the dilution tube Sockets and can move in the axial direction of each other.

Further, the opening portion is provided with a blocking body; the opening portion of the liquid storage tube is located in the dilution chamber.

Further, the blocking body is movably connected to the opening.

For example, the dilution tube is sleeved on the liquid storage tube, and the dilution tube and the liquid storage tube are mutually movable in the axial direction The volume of the dilution chamber changes due to the axial movement of the dilution tube and the reservoir.

The blocking body has a rod portion and a plug end and a collecting end, and the blocking body may not have an collecting end, and the blocking body may also only have a plug end. The plug end and the opening of the liquid storage tube may be sealed and fitted by a sealing guide sleeve, or may be directly engaged with the opening. The collecting end is located in the dilution chamber for collecting secretions or excrement; the diameter of the rod portion is not larger than the diameter of the plug end; the maximum diameter of the rod portion is smaller than the diameter of the plug end: The diameter of the rod portion gradually decreases from the plug end toward the collecting end; or the rod portion is columnar, and the diameter of the rod portion is smaller than the diameter of the plug end, but is not limited thereto. The stem portion may further be provided with a flow guiding groove, and a vent hole may be disposed at the center of the rod portion. The collecting end may be in the shape of a spoon, or the end of the rod may be coated with an absorbent material such as a sanitary napkin, but is not limited thereto, as long as the secretion or the excrement can be collected.

Wherein the disposable sealed body fluid indweller has an isolated state and a dissolved state; when the collecting and diluting device is in the isolated state, the liquid storage chamber and the dilution chamber are separated from each other by the plug end; When the collecting and diluting device is in the solute state, the plug end is not sealingly engaged with the opening portion, for example, the plugging end may be located in the liquid storage chamber, and the liquid storage chamber and the dilution chamber are connected and stored. The diluent in the liquid chamber can flow into the dilution chamber.

Further, the dilution tube includes an annular sidewall and a bottom seal at a bottom end of the annular sidewall. The bottom seal portion and the annular side wall may be integrally formed, and the bottom seal portion is provided with an opening.

It is also possible that the dilution tube comprises the annular side wall comprising a first annular side wall and a second annular side wall, and a bottom seal at the bottom end of the second annular side wall. The bottom seal portion and the second annular side wall may be integrally formed, and the bottom seal portion is provided with an opening. The first annular side wall and the second annular side wall are sealingly fitted, such as a threaded fit.

Further, a filter screen is disposed, the filter screen being located in a lumen of the dilution tube and cooperating with an annular side wall of the dilution tube, the filter screen being located below the occlusion body. The screen is used to filter a solid material of a certain size within the dilution chamber to ensure that there is no large solid matter in the liquid flowing out of the opening.

Further, a disposable sealed body fluid indweller is further provided with an exhaust structure.

Further, a disposable sealed body fluid indweller further includes a drip member that is mated with the opening.

For example, the drip member includes a sealing cover and a pressing rod, the pressing rod is connected to a bottom end of the sealing cover, and the pressing rod is inserted and mated with the opening, and the pressing rod is further provided with Diversion channel. The sealing cover is located in the dilution chamber, the connecting rod portion passes through an opening in a middle portion of the bottom sealing portion of the dilution pipe, and an elastic body such as a spring is disposed between the sealing cover plate and the filter screen .
