Description

Coloring agent container

Technical Field

The utility model belongs to the technical field of medical instrument, a coloring agent container is related to.

Background

Gastrointestinal diseases are common diseases which endanger human health, and even cause death when serious, wherein the incidence and mortality of gastric cancer are the most front of cancers around the world. At present, endoscopy is a first-choice method accepted in gastrointestinal disease examination and diagnosis links, but for some early gastrointestinal diseases, because gastrointestinal mucosa changes slightly, accurate judgment is difficult, and a large amount of missed diagnoses exist in endoscopy.

The invention of the alimentary canal mucous membrane coloring agent brings great convenience to the endoscopy, and the coloring agent is used in an auxiliary way on the basis of the conventional endoscopy, so that compared with normal tissues, the lesion focus shape and range of the sprayed coloring agent are clearer, and the capability of naked eye identification can be improved. The coloring agent is generally deposited in the container body, and during the use, utilizes this internal piston of container and piston rod to push the coloring agent outside the container body, can extrude the coloring agent from this internal complete of container for guaranteeing the piston, and the length of piston rod must have sufficient length. When more coloring agents are contained in the container body, most of the piston rod extends out of the container body, and occupies more external space, so that space resources are wasted. Meanwhile, the piston rod extends out of the container body, so that the container is not convenient to place.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a coloring agent container simplifies the structure, reduces the required space that occupies of vessel, does benefit to and puts.

In order to achieve the above object, the basic scheme of the utility model is: a coloring agent container comprises a container body and a rodless piston assembly, wherein a material conveying port is formed in one end of the container body, and the rodless piston assembly is connected with the inner wall of the container body in a sliding and sealing mode.

The working principle and the beneficial effects of the basic scheme are as follows: the rodless piston assembly does not need to be controlled by a push rod, so that the structure is more compact, the occupied space is small, and the arrangement is facilitated. When the container body is vertically placed, the end part of the container body can be directly contacted with the placing plane, a positioning assembly does not need to be arranged outside, and the movement of the rodless piston assembly is not influenced.

Further, when the container is placed, the container body is vertically arranged, and the material conveying opening is positioned at the top of the container.

The coloring agent container is vertically arranged, air in the container is exhausted in use, the influence of bubbles on flow is avoided, and the stability of the flow in the use process is ensured.

Further, the rodless piston assembly is a magnetic coupling rodless piston or a mechanical rodless piston.

The rodless piston has a compact structure, requires less space and is beneficial to placement and use.

Further, rodless piston assembly includes piston and sealing washer, is equipped with the annular on the outer wall of piston, and the sealing washer sets up in the annular, and the sealing washer offsets with the container body inner wall.

And a sealing ring is arranged on the outer wall of the piston, so that the sealing performance of the piston is enhanced by the sealing ring.

Furthermore, the outer side of the container body is sleeved with an elastic sleeve, and the elastic sleeve is light-transmitting or light-proof.

The elastic sleeve has certain elastic buffering acting force, can protect the coloring agent container and avoids the coloring agent container from colliding and damaging. And the light transmissivity of elastic sleeve sets up for hold as required and need not the different demands of light-resistant storage and the storage of needs light-resistant.

Furthermore, a sealing plug is arranged at the material conveying opening.

The sealing plug prevents that the coloring agent in the coloring agent container from failing material delivery port department mistake and flowing out, only when using the coloring agent, just takes off the sealing plug from defeated material delivery port department.

Furthermore, the bottom of the rodless piston assembly is provided with a reflector plate.

The reflector plate is arranged to serve as a marker, so that the position of the rodless piston assembly can be detected conveniently, and the volume of the coloring agent in the coloring agent container can be detected.

Furthermore, the bottom of the rodless piston assembly is provided with a groove, and the reflector plate is fixedly arranged in the groove.

The reflector plate is arranged in the groove, and the groove plays a role in protecting the reflector plate.

Further, the container body is made of light-transmitting materials or light-proof materials.

The user selects container body printing opacity or light-tight as required, and this internal dyeing agent surplus of container is convenient for look over to container body printing opacity, and light-tight container body does benefit to the dyeing agent that the protection needs to keep out of the sun.
