Description
Technical field
This utility model relates to armarium, particularly relates to a kind of rat jugular vein retained transfusion device.
Background technology
Rat jugular vein tube placing operation is widely used in animal model and experiment, but there is the problem of not easy care during practical application.As pipe obstruction, come off, make the continuous experiment being difficult to animal individual be carried out to the long period.To be put the pertinent literature of pipe for a long time about rat jugular vein by retrieval, find that current tube indwelling technology also stays in and cut off by rat jugular vein, put the stage of Guan Houzai ligation, the method is length consuming time not only, and success rate is not high, and put pipe for a long time and easily come off.In prior art, although there also have medical treatment device and rat jugular vein to put pipe administration to be relevant, this product is only suitable for single-dose, can not realize the long term administration of rat.
Conventional rat jugular vein is put pipe and is divided into two steps.
The first step: jugular vein intubation: get dorsal position after Animal Anesthesia, optional side preserved skin, cuts 1 ~ 1.5cm from outside upper to interior lower diagonal, isolates jugular vein to deep layer.Ligation jugular vein far-end, centripetally on vein tube wall does " V " type otch, and penetraction depth is 1/2 ~ 2/3 of vein, and will be filled with the silica gel tube of heparin in advance from the centripetal insertion of incision, the degree of depth is about 2.5cm.Silica gel catheter is fixed in ligation, pushes away the syringe taken out and be connected with catheter tip, if intubate is normal, feel smooth and easy when pushing normal saline, pumpback has blood.
Second step: neck back surgery: after neck and chest has been performed the operation, animal is prostrate, and nape preserved skin, crosscut skin is about 1cm.With rustless steel guiding tube from two otch behind subcutaneous through throat, silica gel tube free-end, from after wherein causing neck, is fixed on partial musculature, skin suture.
By rat jugular vein of the prior art put pipe complete operation time, usually there is following drawback.
1, rat jugular vein is after separation surrounding tissue, and blood vessel wall loses surrounding tissue and supports, and is easy to shrivelled.
2, this action need is by vein scissors one osculum, and because vein is shrivelled, silica gel catheter is not easy to insert in osculum very much, not only expends time in, and is easily interrupted by vein.
3, silica gel catheter is commonly used at present as epidural catheter.This conduit, after passing after rat neck, because the elasticity of conduit own and conduit are at subcutaneous rat crooked radian, easily cause intravenous terminal spine to break wall of vein or conduit slides at intravenous in indwelling process, causes conduit to deviate from.
4, put pipe success rate not high, waste time and energy, and new hand just can skilled operation after needing being familiar with of a period of time.
Utility model content
The purpose of this utility model is: provide a kind of rat jugular vein retained transfusion device, it solve at least one shortcoming in prior art, and can realize the long term administration of rat.
The technical scheme reaching described object is: a kind of rat jugular vein retained transfusion device, it comprises
One connection tube, described connection tube inside is cavity structure, and the front and back end of described connection tube and middle part are equipped with the connecting hole being communicated with described cavity structure;
One internal jugular vein section conduit, described internal jugular vein section tube at one end is connected to the connecting hole of described connection tube front end;
One puncture needle, the front stage casing of described puncture needle is built in described internal jugular vein section conduit and described connection tube, and described puncture needle back segment stretches out the rear end connecting hole of described connection tube;
The outer extraction catheter of one neck, the outer extraction catheter one end of described neck is connected to connecting hole in the middle part of described connection tube, and the other end connects one for connecting the attachment cap of syringe;
Wherein, the link position of above-mentioned all parts and connecting hole all seals setting.
Connecting hole position, described connection tube rear end is provided with a rubber closure.
Described connection tube is transparent tee T.
The advantage of technique scheme is: rat jugular vein retained transfusion device of the present utility model, and structure is simple, and easy and simple to handle, success rate is high, almost reach 100%, the operating time is short, dramatically saves on the time of experimenter, and fixation, little to rat wound, post-operative recovery is fast.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model will be further described.
Fig. 1 is the vein detaining needle for fluids infusion apparatus structure schematic diagram of this utility model embodiment.
Wherein.
1 connection tube; 2 internal jugular vein section conduits; 3 puncture needles;
The outer extraction catheter of 4 necks; 5 rubber closures; 6 attachment caps.
Detailed description of the invention
Embodiment: as shown in Figure 1, a kind of rat jugular vein retained transfusion device, it comprises connection tube 1, internal jugular vein section conduit 2, puncture needle 3, neck outer extraction catheter 4, attachment cap 6.
Connection tube 1 inside is cavity structure, and the front and back end of connection tube 1 and middle part are equipped with and are communicated with described cavity structure connecting hole.Connection tube 1 can be set to transparent tee T, and the concrete shape of connection tube 1 adopts according to actual needs.
Internal jugular vein section conduit 2 one end is connected to the connecting hole of connection tube 1 front end.
Puncture needle 3 front middle part is built in internal jugular vein section conduit 2 with in connection tube 1, and puncture needle 3 rear portion is stretched out by the rear end connecting hole of connection tube 1.Puncture needle 3 can be elastic in internal jugular vein section conduit 2 with connection tube 1, realizes the function of puncture.
Outer extraction catheter 4 one end of neck is connected to connecting hole in the middle part of described connection tube 1, and the other end connects one for connecting the attachment cap 6 of syringe; Wherein, the link position of above-mentioned all parts and connecting hole all seals.
Connecting hole position, connection tube 1 rear end is provided with a rubber closure 5, and the conduct of rubber closure 5 is, when puncture needle 3 pairs of rat neck punctures, and realizes good sealing effectiveness when intravenous injection.
In the specific implementation, utilize the rat jugular vein retained transfusion device concrete operations of the present embodiment as follows.
1: the shrivelled rearmounted pipe of rat vein: even if rat vein is shrivelled, conduit is under the guiding of built-in puncture needle 3, as long as puncture needle 3 penetrates jugular vein smoothly, conduit can be inserted.
2: ensure after putting pipe that conduit is not deviate from jugular vein: transparent threeway is connected with the section of extraction conduit after internal jugular vein section conduit 2 and neck, with suture, the tissues surrounding vascular section of extraction conduit angle after transparent threeway and neck is sewed up, firmly can keep the not slippage of internal jugular vein section conduit 2.
3: reduce tube tension, make conduit not because own tension slippage or puncturing veins: because internal jugular vein section conduit 2 is connected with there being a transparent threeway after neck between the section of extraction conduit, two sections of conduits are not directly connected, therefore no-station pole canopy.
4: after ensureing the neck of conduit, traversing through end is fixed, and is not shut down: by attachment cap 6 partial fixing in subcutaneous rat by rat, and through the aperture of attachment cap 6 both sides, attachment cap 6 is fixed on rat skin with suture.
It should be pointed out that for this utility model through absolutely proving, also can have the embodiment of multiple conversion and remodeling, be not limited to the specific embodiment of described embodiment.Described embodiment as just explanation of the present utility model, instead of to restriction of the present utility model.In a word, protection domain of the present utility model should comprise those apparent conversion or alternative and remodeling to those skilled in the art.
