Abstract
The utility model discloses a kind of laboratory animal Culling heart blood pin, comprise syringe needle, the pintle of the needle point that described syringe needle obstructs primarily of the pin of elongated tubular product, pin obstructs front end and pin stalk rear end is formed, described needle point is flat round shape, and the tube wall of described pin stalk is provided with the stopping means for limiting syringe needle feeding depth.Laboratory animal Culling heart blood pin of the present utility model, can both ensure the accuracy of blood sampling point to the blood sampling at different laboratory animal heart places, the effective injury reducing blood taking needle and cause, reduces fatality rate to a great extent.
Description
Technical field
This utility model relates to a kind of scientific experiments instrument and equipment, particularly a kind of laboratory animal Culling heart blood pin.
Background technology
To in the experimentation of zooscopy, usually adopt the mode of blood taking needle to the animal blood taking of experiment, carry out serum test, for experimental analysis.In prior art, Blood collection is roughly divided into following several: 1, take a blood sample from the eyes of laboratory animal, the blood volume foot that can take, but easily causes animal dead; 2, from the tail vein blood of laboratory animal, the blood volume that can take is few, and blood sampling efficiency is relatively low; 3, from the Culling heart blood of laboratory animal, the blood volume foot that can take, but require higher to blood-taking device.
In order to be conducive to the carrying out of subsequent experimental research, often adopting and taking a blood sample to animal hearts, the laboratory animal after blood sampling need continue survival.But the syringe needle of existing blood taking needle is point, cardia is weaker, and prong easily causes larger secondary injury to animal, and fatality rate is high; Meanwhile, due to varying in size of laboratory animal, it is also different that heart is in subcutaneous position, is difficult to the degree of depth controlling pin insertion.
Visible, design syringe needle that a kind of minimizing damages laboratory animal and the animal hearts blood taking needle that accurately can control insertion depth be industry in the urgent need to.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of laboratory animal Culling heart blood pin, the accuracy of blood sampling point can both be ensured to the blood sampling at different laboratory animal heart places, the injury that effective minimizing blood taking needle causes, reduces fatality rate to a great extent.
Solve the problems of the technologies described above, this utility model adopts following technical scheme:
Laboratory animal Culling heart blood pin, comprise syringe needle, the pintle of the needle point that described syringe needle obstructs primarily of the pin of elongated tubular product, pin obstructs front end and pin stalk rear end is formed, and described needle point is flat round shape, and the tube wall of described pin stalk is provided with the stopping means for limiting syringe needle feeding depth.
In such scheme, described stopping means is that annular offers boss or groove on the sidewall of pin stalk, and described boss or groove are arranged with suitable medical silica-gel circle.
As the further improvement of such scheme, described stopping means is at least 2, and this stopping means is that forward and backward interval is arranged along the axial direction that pin obstructs.
As the further improvement of such scheme, the radial radius of described each stopping means increases from front to back successively.
In such scheme, described pin obstructs for stainless steel material is made.
Compared with prior art, the beneficial effects of the utility model are:
1, laboratory animal Culling heart blood pin of the present utility model have employed the syringe needle of flat circle design, can reduce the injury that syringe needle causes laboratory animal, effectively reduce the fatality rate of animal subject;
2, the boss offered on the sidewall of pin stalk or groove can control the feeding depth of blood taking needle, can ensure the accuracy of blood sampling point to different animal subject;
3, there is medical silica-gel circle at boss or groove overcoat, the liquid outflow when taking a blood sample can being prevented.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is pin of the present utility model stalk side wall surface boss structure schematic diagram;
Fig. 3 is pin of the present utility model stalk side wall surface groove structure schematic diagram.
Wherein, Reference numeral is respectively: 1, pin stalk; 2, needle point; 3, pintle; 4, boss; 5, groove; 6, silica gel ring.
Detailed description of the invention
A kind of laboratory animal Culling heart blood of this utility model pin, comprise syringe needle, described syringe needle obstructs primarily of the pin stalk 1 of elongated tubular product, pin the pintle 3 that the needle point 2 of 1 front end and pin obstruct 1 rear end and forms, described pin stalk 1 is made for stainless steel material, described needle point 2, in flat round shape, effectively reduces the injury that needle point 2 causes; The tube wall of described pin stalk 1 is provided with the stopping means for limiting syringe needle feeding depth, and described stopping means is that on the sidewall of pin stalk 1, annular offers boss 4 or groove 5, for limiting the insertion depth of pin stalk; Meanwhile, outside boss 4 or groove 5, be arranged with suitable medical silica-gel circle 6, effectively can prevent the outflow of liquid in blood collection procedure,
Wherein, described stopping means is at least 2, and the axial direction that this stopping means obstructs 1 along pin is that forward and backward interval is arranged, and can use, make blood taking needle applicable surface of the present utility model wider for kinds of experiments animal body; Further, the radial diameter of described each stopping means increases from front to back successively, during use, is easy to control the degree of depth to different experimental animals Culling heart blood points, makes operator more accurate.
Certainly; just by reference to the accompanying drawings the preferred detailed description of the invention of this utility model is described in detail above; not limit practical range of the present utility model with this; all equivalence changes done according to principle of the present utility model, structure and structure, all should be covered by protection domain of the present utility model.
