Background technology
Using mice to carry out zoopery is the method that present many medical researches will be used, and to carry out administration by gavage in experimentation be a kind of conventional administering mode, at present the conventional irrigation stomach device many employings metal needle of gavage is carried out to mice, its quality is hard, needle point is sharp, and the esophagus of mice is thinner, in gavage process, the careless slightly damage that will cause the position such as throat, esophagus, stomach of mice, even causes dead mouse; Existing irrigation stomach device also requires high to the skills involved in the labour of operator, otherwise mice health can be damaged equally, cause gavage failure, carry out repeatedly in the experimentation of gastric infusion at needs, because gavage success rate is low, experimentation small mouse is large due to the damage quantity caused of gavage, affects experimental result.
Summary of the invention
This utility model is intended to solve existing irrigation stomach device and easily mice is caused to damage, uses the technical problem inconvenient, gavage success rate is low.
For solving the problems of the technologies described above, this utility model adopts following technical scheme:
Design a kind of mouse stomach device, comprise syringe, at the liquid outlet of described syringe, gastric perfusion needle is installed, protecting tube is set with at the outer surface of described gastric perfusion needle, spherical termination is provided with in the lower end of described protecting tube, in described spherical termination, be provided with its two ends through hole through, the internal diameter of described through hole is equal with the internal diameter of described protecting tube; Described protecting tube and spherical termination are rubber or silica gel material; Be provided with union joint in the upper end of described protecting tube, described union joint cooperation is installed on outside the needle holder of described gastric perfusion needle.
Preferably, described gastric perfusion needle is polypropylene material.
Preferably, described gastric perfusion needle is elbow pin, and its front end 1/3 place and its top are the bending angle of 130 ~ 160 degree.
Preferably, the length of described gastric perfusion needle is 40 ~ 90mm.
Preferably, the union joint of described protecting tube is also provided with seal cover.
Preferably, be provided with contact band at the top of described seal cover, described seal cover is connected on the outer wall of described protecting tube upper end by described contact band.
Preferably, described seal cover is quality of rubber materials.
The beneficial effects of the utility model are:
1. spherical termination is set in gastric perfusion needle outer setting protecting tube, protecting tube bottom, gastric perfusion needle can be avoided directly to contact throat, esophagus, the stomach of mice, prevent gastric perfusion needle from damaging the position such as throat, esophagus, stomach of mice; Protecting tube and spherical termination adopt rubber or silica gel material, have good elasticity, to the zest of Mouse Esophageal or injury when can reduce gavage further.
2. gastric perfusion needle adopts polypropylene material, makes gastric perfusion needle inherently have certain elasticity and bending, deformation nature, is more convenient to the esophagus inserting mice in use, overcomes the defect of metal material due to the hard easy damage Mouse Esophageal of quality.
3. this mouse stomach device can after gastric perfusion needle inserts mice stomach, gastric perfusion needle is extracted out, and protecting tube is stayed in Mice Body, protecting tube upper end union joint is placed in outside mice mouth, when next administration, feeding, can directly medicinal liquid or slop be delivered in the stomach of mice by protecting tube, be convenient to repeatedly directly administration, feeding, reduce gavage number of times; Seal cover is set at protecting tube connector position, after administration or feeding, seal cover is built, can prevent foreign body or air from entering protecting tube; Seal cover is connected with protecting tube by contact band, can prevent seal cover from coming off, losing, convenient during use, and seal cover adopts quality of rubber materials, and sealing effectiveness can be made better.
4. this utility model convenient operation, less demanding to the skills involved in the labour of operator, significantly can improve the success rate of gavage in experimentation, and reduce the damage to mice, and production cost is low, the scope of application is more extensive.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model mouse stomach device.
Fig. 2 is the structural representation of protecting tube in Fig. 1.
Wherein, 1 is syringe; 2 is protecting tube; 3 is spherical termination; 4 is union joint; 5 is needle holder; 6 is seal cover; 7 is contact band.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described, but the following example is only used to describe embodiment of the present utility model in detail, and limits scope of the present utility model never in any form.
Embodiment 1: a kind of mouse stomach device, see Fig. 1, Fig. 2, comprise syringe 1, at the liquid outlet of syringe 1, gastric perfusion needle is installed, protecting tube 2 is set with at the outer surface of gastric perfusion needle, be provided with spherical termination 3 in the lower end of protecting tube 2, in spherical termination 3, be provided with its two ends through hole through, the internal diameter of through hole is equal with the internal diameter of protecting tube 2; Protecting tube 2 and spherical termination 3 are quality of rubber materials; Union joint 4 is provided with in the upper end of protecting tube 2, union joint 4 cooperation is installed on outside the needle holder 5 of gastric perfusion needle, the union joint 4 of protecting tube 2 is also provided with seal cover 6, contact band 7 is provided with at the top of seal cover 6, seal cover 6 is connected on the outer wall of protecting tube 2 upper end by contact band 7, and seal cover 6 is quality of rubber materials.Wherein, gastric perfusion needle is polypropylene material, and according to the difference of concrete model, its length is between 40 ~ 90mm.
Embodiment 2: a kind of mouse stomach device, is with the difference of embodiment 1, protecting tube 2 and spherical termination 3 are medical silica-gel material;
