Abstract
The utility model discloses a rat stomach perfusing and medicine applying device which is a round tube; one end of the round tube is a base connected with an external transfusion device, the other end of the round tube is a needle, and the part between the base and the needle is a medicine applying conduit; and the inner diameter of the round tube is gradually reduced along the base, the medicine applying conduit and the needle. In the rat stomach perfusing and medicine applying device with the structure, the base, the medicine-application conduit and the needle have an integral structure in smooth transition, thus avoiding roughness and unevenness caused by three-section connection. The rat stomach perfusing and medicine applying device has a thin wall, larger inner diameter and moderate hardness, is especially applicable to the rat stomach perfusing and medicine applying operation of indissolvable liquid test samples which are thick in concentration, large in particle and easy to block, and has the advantages of being convenient to operate, wide in application rage, good in animal comfort level, simple in design, convenient to produce, transparent and easy to clean, extremely low in cost, reusable in resource and the like.
Description
Technical field
This utility model relates to medicine and pharmacology animal experiment device capable field, particularly a kind of rat oral gavage doser.
Background technology
The rat oral gavage doser is commonly used with the indispensable experiment equipments of all kinds of medicine and pharmacology zooperies, and the per os gastric infusion that is used to be tried thing is operated.
At present; Domestic existing conventional rat oral gavage doser (as: irritating the stomach pin); Mainly process by metal material, the metal base 6 that the essential structure of described filling stomach pin is divided into the metal needle of falling the droplet-shaped 4, metal catheter 5 and is connected with syringe, its structure is as shown in Figure 2.Yet in practical application, find: all thin (about 1-1.5mm) and full section etc. are thick for metal catheter 5 internal diameters of conventional rat oral gavage pin; Be used to give that concentration is thicker, during the big medicinal liquid (like Chinese medical concrete, insoluble medicine suspension etc.) of granule; Thing occurs being tried through regular meeting and stop up and can't see phenomenon such as metal catheter 5 inner liquid medicines, influenced the accuracy and the work efficiency of administration to a certain extent; In addition, it is too directly too hard that metal is irritated the stomach pin, when inserting the animal esophagus, the fixing operation of animal had relatively high expectations, and generally wants earlier by force with the neck reason directly, and the animals comfortable degree is bad.
Summary of the invention
This utility model provide a kind of simple and practical, cost is low, be prone to make, the animals comfortable degree is good, high efficiency, rat oral gavage doser applied widely.
A kind of rat oral gavage doser is a pipe; The pedestal of one end of described pipe for being connected with external infusion equipment, the other end is a syringe needle, the part between described pedestal and the syringe needle is a delivery catheter; The internal diameter of described pipe dwindles along pedestal, delivery catheter and syringe needle gradually.Pedestal, delivery catheter become the integrative-structure of rounding off in the rat oral gavage doser of this structure with syringe needle, have avoided syllogic to interconnect the rough and uneven in surface of existence.
In order to reach better effect, preferably:
Described delivery catheter is curved near the part of syringe needle.Described arcual radian is unsuitable excessive, is generally 10 degree-60 degree.
According to actual needs, the total length of described pipe is 7cm-9cm.
The internal diameter of described syringe needle is 1.5mm-2.0mm.
Described pipe is selected transparent rigid plastics pipe for use.
The pipe method for preparing of described integrative-structure is simple; Can adopt existing drawing forming technique that the plastic conduit of hollow transparent is once drawn molding behind hot mastication; Then the one of which end is expanded into the pedestal that is connected with external infusion equipment, other end cutting polishing is slick and sly as syringe needle.
Compared with prior art, the utlity model has following advantage:
1) this utility model rat oral gavage doser wall is thin, transparent, internal diameter is big (can require to cut arbitrarily the less end of round tube inside diameter to form the bigger syringe needle of new internal diameter according to reality), the difficult obstruction; Applied widely; Be specially adapted to the per os gastric infusion that concentration is thick, granule big, easy stifled indissoluble is tried thing and operate, improved the quality and the efficient of rat oral gavage greatly.
2) this utility model rat oral gavage doser hardness is moderate and have a little radian near the part of syringe needle, to adapt to the camber of animal bottleneck throat, is convenient to light insertion, and is easy to operate, reduces the mechanical injuries to the animal esophagus simultaneously, and the animals comfortable degree is better.
3) this utility model rat oral gavage doser simplicity of design, simple for production, easy cleaning.
4) super cheap, the environmental emission reduction of this utility model rat oral gavage doser cost, resource reutilization (can select the empty pen core of disposable water-color paintbrush for use like raw material, realize that waste recovery utilizes again, reduce and pollute).
Description of drawings
Fig. 1 is the structural representation of this utility model rat oral gavage doser;
Fig. 2 is the structural representation that existing metal is irritated the stomach pin.
The specific embodiment
As shown in Figure 1, this utility model rat oral gavage doser is a transparent rigid plastics pipe; The pedestal 1 of one end of pipe for being connected with external infusion equipment, the other end is a syringe needle 2, the part between pedestal 1 and the syringe needle 2 is a delivery catheter 3; The internal diameter of pipe dwindles along pedestal 1, delivery catheter 3 and syringe needle 2 gradually.The integrative-structure of pedestal 1,2 one-tenth rounding ofves of delivery catheter 3 and syringe needle has avoided syllogic to interconnect the rough and uneven in surface of existence in the rat oral gavage doser of this structure.
According to actual needs, the total length of pipe is 7cm-9cm, and the internal diameter of syringe needle 2 is 1.5mm-2.0mm.
The pipe of integrative-structure can adopt existing drawing forming technique that the plastic conduit of hollow transparent is once drawn molding behind hot mastication; Then the one of which end is expanded into the pedestal 1 that is connected with external infusion equipment, other end cutting polishing is slick and sly as syringe needle 2.
The operating instruction of this utility model rat oral gavage doser: the syringe that will take out the examination thing (solution or suspension etc.) of feeling better connects the pedestal 1 of rat oral gavage doser; With conventional method grasp, fixing animal, the animal outside of belly is towards irritating the stomach person, then with arcwall face (being one side downward among Fig. 1) back of the body subsides animal oral cavity of rat oral gavage doser, along the insertion of slowly taking advantage of a situation of esophagus rear wall; After injecting the suitable degree of depth (about 5cm); Inject, extract, promptly accomplish and irritate the stomach operation.
