Description
Technical field
This utility model belongs to medicine and pharmacology zoopery instrument field, specifically, is a kind of arterial cannulation assembly.
Background technology
During medicine and pharmacology zoopery, many zooperies are required for doing arterial cannulation, can be adopted by arterial cannulation
Blood sets up laboratory observation index, and in research aircraft body, the change of the index such as every physiology, pathology, immunity, is a kind of convenience and high-efficiency
Experimentation technology.Wherein rat carotid artery intubation is a kind of modal animal blood vessels intubation model.
Tightened after intubation and blood vessel with line, because catheter surface is smooth not after the arterial cannulation insertion blood vessel commonly using now
Easily firmly ligature and easily shift or slip；The tiny conduit mouth in intubation front end is attached at blood vessel and easily causes catheter blockage, meeting
Cause blood sampling volume not enough and the obstructed problem of intubation intravascular coagulation intubation；And intubation blood flow rate controls inconvenience, easily causes red
Cell ruptures haemolysis, the success or failure of the whole experiment of impact after washing away.
Chinese utility model patent CN202314847U discloses a kind of arterial cannulation, includes joint, flexible pipe, taper are worn
Pricker, its center tap is connected to one end of flexible pipe, and taper puncture needle is connected to the other end of flexible pipe, and the syringe needle of taper puncture needle is in
Horse hoof face.But still suffer from needing fixing taper puncture needle with cotton thread, the problem that during blood sampling, blood flow rate cannot control.
Utility model content
For solve above-mentioned prior art defect, this utility model provide a kind of easy intubation, be fixed easily, do not block, blood flow
The rat carotid artery cannula assembly that speed can control.
For reaching above-mentioned purpose, the technological means that this utility model adopts are：A kind of arterial cannulation assembly, including flexible pipe,
Angiographic neeclle and intubation folder, the entrance point of described flexible pipe is affixed with angiographic neeclle, the port of export of flexible pipe and syringe phase
Join, described angiographic neeclle is tapered, described flexible pipe is provided with administration joint and actuator, described administration joint and syringe phase
Join.
Further, described intubation folder is fixed at the entrance point of flexible pipe by tether.
Further, the length of described angiographic neeclle is 2-4cm, and internal diameter is 0.1-0.2mm.
Further, described flexible pipe is igelite.
Further, the quantity of described intubation folder is two.
The beneficial effects of the utility model are：
1st, this utility model overcomes the easy slippage of traditional cannulas and is not fixed easily, and in pipe, easily blocking, secondary use clean difficulty
The shortcomings of, there is structure simply, be easy to intubation and fixation, the advantage being easy to cleaning.
2nd, this utility model is provided with administration joint on flexible pipe, can be used for injecting heparin normal saline dilution liquid and carries out " punching
Pipe is processed ", prevent catheter blockage, or injection other drugs carry out Experiment intervention.
3rd, this utility model is provided with actuator on flexible pipe, has hosepipe switch concurrently and adjusts intubation blood flow rate function.
Brief description
Fig. 1 is structural representation of the present utility model；
In figure：Angiographic neeclle 1；Administration joint 2；Actuator 3；Flexible pipe 4；The port of export 5；Intubation folder 6.
Below in conjunction with brief description and specific embodiment, structure of the present utility model is further described in detail, attached
Figure is the schematic diagram simplifying.
Specific embodiment
As shown in figure 1, a kind of schematic diagram of the arterial cannulation providing for this utility model, including flexible pipe 4, angiographic neeclle
1 and intubation folder 6, described flexible pipe 4 is made using igelite, and the entrance point of flexible pipe 4 is affixed with angiographic neeclle 1, soft
The port of export 5 of pipe and 2ml or 5ml syringe match, and described angiographic neeclle 1 is tapered, and its length is 2-4cm, and internal diameter is
0.1-0.2mm, described flexible pipe 4 is provided with administration joint 2 and actuator 3, and administration joint 2 is matched with 2ml or 5ml syringe,
Described intubation folder 6 can be fixed at the entrance point of flexible pipe 4 by tether, and the quantity of intubation folder 6 is two, in the design, intubation
Folder had both been connected on flexible pipe, made an assembly with flexible pipe, purpose is easy to the fixation to blood vessel and angiographic neeclle, certainly, inserted
Pipe clamp can also individually be deposited and take.
During as carried out rat carotid artery intubation, postanesthetic rat being lain on the back and is fixed on operating-table, on the right side of cervical region
Longitudinally slit skin, with mosquito forcepss blunt separation fascia, spatium intermusculare, right carotid 1-1.5cm of dissociating, bulldog clamp will be swum
The tremulous pulse two ends separating out are clamped, and 30 ° -45° angle of ophthalmology curved scissors cuts an osculum on the artery segment isolated, will with blade holder
Tremulous pulse is provoked, and conical blood vessel puncture needle is inserted tremulous pulse；Pressed from both sides right carotid blood with two intubations at flexible pipe entrance point
Fixation clamped by pipe and angiographic neeclle.
In said process, can be injected by being administered joint if desired for injecting heparin normal saline dilution liquid or other drugs,
Administration joint both prevented catheter blockage, was also used for carrying out Experiment intervention, when needing to take blood, opening governor switch can be from outlet
End blood-letting enters test tube, and actuator also can be used to regulating blood flow speed, after taking blood to finish, can extract normal saline by syringe
Or heparin medicinal liquid is connected washing pipe with the port of export, that is, complete the washing pipe work of arterial cannulation；Can be used for many animals for example Canis familiaris L., rabbit,
The intubation of rat and mice is it can also be used to stock, carotid artery and/or neck, femoral vein blood cannula model.
Below schematically this utility model and embodiments thereof are described, this description does not have restricted, accompanying drawing
Shown in be also one of embodiment of the present utility model, actual structure is not limited thereto.So, if this area
Those of ordinary skill enlightened by it, without departing from this utility model create objective in the case of, design without creative
The frame mode similar to this technical scheme and embodiment, all should belong to protection domain of the present utility model.
