Description

A kind of gastric juice collection tube of animal

Technical field

The utility model relates to experimental animal apparatus, more particularly to one kind to have extensively for experiments such as beasle dogs with big animal The gastric juice of general applicability acquires equipment.

Background technique

Conventional big animal gastric juice collection tube is the rubber tube of a pipe shape upper and lower opening, this pipe is inserted directly into stomach, Injector for medical purpose is used in combination and extracts gastric juice.But the more difficult depth for accurately controlling gastric juice collection tube insertion stomach of this method, if It was inserted into and is deep to stomach bottom, the possibility of acquisition is not gastric juice but stomach bottom liquid；If be inserted into shallowly, may extract less than gastric juice； If touching gastric content, gastric juice can not be accurately obtained, to influence final diagnosis.

Summary of the invention

The purpose of this utility model is directed to a kind of gastric juice collection tube of animal, overcomes traditional equipment insertion depth with this The problem for being difficult to hold, gastric juice acquisition difficulty is big.

The utility model realizes that the technical solution of above-mentioned purpose is that a kind of gastric juice collection tube of animal, feature exists It is that hollow rubber tube, the open top of rubber tube, bottom closure, and the nearly bottom sidewall of rubber tube are equipped with perforation to rubber in main body The open-work of sebific duct inner cavity.

Further, rubber tube open-work side in nearly bottom sidewall is equipped with pH test paper.

Further, the pH test paper is attached at the circumferential outer ring of rubber tube.

Further, the open-work is intensive mesh, and the internal diameter of each open-work is less than the intracavity diameter of rubber tube.

Further, the intensive mesh is array hole, helical arrangement hole or the irregular discrete shape of proper alignment Aligned apertures.

Further, the open top of the rubber tube connects with the matching of 10ml injector for medical purpose.

Using the gastric juice collection tube of the utility model, have substantive distinguishing features and progressive: closed by design bottom Collection tube can go directly and stomach depths and can effectively avoid collecting stomach bottom liquid and other contents, be able to by the presentation of pH test paper Gastric juice collected is judged, so as to the experimental precision of clinicing aspect.

Specific embodiment

Just attached drawing in conjunction with the embodiments below, is described in further detail specific embodiment of the present utility model, so that this Utility model technical solution is more readily understood, grasps, to make relatively sharp define to the protection scope of the utility model.

In view of existing many deficiencies for big animal acquisition gastric juice equipment aspect, the design person is researched and analysed and is innovated A kind of gastric juice collection tube of animal is proposed, overcomes traditional equipment insertion depth to be difficult to hold with this, gastric juice acquisition difficulty is big Problem.

Shown in as shown in Figure 1, Figure 3 and Figure 4, the preferred embodiment schematic structure of the gastric juice collection tube can be summarized are as follows: its main body For hollow rubber tube 1, top 11 open (shown in Fig. 3), the bottom 12 of rubber tube are closed (shown in Fig. 4), and the nearly bottom of rubber tube 1 Portion's side wall is equipped with the open-work 2 of perforation to rubber tube cavity.So, the acquisition channel of collection tube is effectively turned to, and is no longer Tradition is axially carried out along collection tube, can effectively avoid the through acquisition bottom of the tube opening of tradition due to insertion depth difference thus Collect the embarrassment of non-gastric juice.The collection tube of the design by separately to the open-work of filter opening rank be acquired gastric juice, to adopt Collection efficiency and accuracy significantly improve.

Further refinement and optimization as scheme outlined above.Above-mentioned rubber tube 12 side of open-work in nearly bottom sidewall Equipped with pH test paper 3.And the pH test paper 3 is attached at the circumferential outer ring of rubber tube.To judge that acquisition closes whether bottom is dipped into In acid gastric juice, confirm that the liquid of acquisition is gastric juice.

And above-mentioned open-work is intensive mesh, and the internal diameter of each open-work is less than the intracavity diameter of rubber tube.As shown in Figure 1 Preferred embodiment, the intensity mesh be proper alignment array hole.Because acquisition content is liquid, from illustrating, visible this is intensive The area summation of type mesh is much larger than the diameter of collection tube itself inner cavity, by increasing open-work quantity, reducing aperture, reaches satisfaction Tradition acquisition reduces impurity in stomach and is mixed into while absorbing freight volume, improve the efficiency and quality of gastric juice acquisition.

In addition, the open top of the rubber tube connects with the matching of 10ml injector for medical purpose, it is desirable to provide the source of gastric juice acquisition Power operates convenient for experimenter.

In addition to above preferred embodiment, the utility model gastric juice collection tube can also have preferable reality as shown in Figure 2 Example is applied, wherein most constructions feature is identical as preferred embodiment, and difference is that the intensity mesh is helical arrangement hole, During acquiring gastric juice, or even certain vortex can be formed in pipe, further acquire raising efficiency, reduce syringe behaviour Make external force.Certainly, which can also be irregular discrete shape aligned apertures, and hereby it will not go into details and diagram.

The practicality is understood from the concrete operations of the utility model gastric juice collection tube: first by the bottom of the gastric juice collection tube Portion is suitably wet (avoiding the rough property damage in insertion animal physiological disposition), then along left side tongue be slowly rotatably inserted into Until can not being inserted into, i.e. acquisition bottom of the tube touches stomach wall.After then extracting liquid using sterilized medical syringe, slowly extraction is adopted Collector, checks the color of the pH test paper rule, so that whether judge to extract is gastric juice, then carries out subsequent experimental implementation.By This is as it can be seen that the process will not generate damage and scaring to collected object, while collection process is simple, gained liquid is reliable.

To sum up about the detailed description of embodiment as it can be seen that using the utility model gastric juice collection tube, have substantive spy Point and progressive.From the point of view of specific, can be gone directly by the closed collection tube in design bottom stomach depths and can effectively avoid acquiring It to stomach bottom liquid and other contents, is able to judge gastric juice collected by the presentation of pH test paper, so as to the experiment essence of clinicing aspect Degree.

The utility model is described in detail above by specific embodiment, which is only the utility model Preferred embodiment, not to the restriction of requested protection scope.In the case where not departing from the utility model principle, ability Any modification, equivalent substitution and improvement that domain those of ordinary skill is done under the premise of without creative work it is obtained its Its embodiment, is regarded as in the technical protection scope of the utility model.
