Description
Technical field
This utility model relates to a kind of Neurology Department and to infuse special puncture needle.
Background technology
Existing neural puncture needle is a hollow syringe needle.During use, puncture needle is connected on syringe, syringe needle is sent to appointed part in human body with hand-tight syringe of holding, then by the medicinal liquid in syringe as anaesthetic is input to this position, to realize medical object.This kind of puncture needle pierces in human body owing to must be driven by syringe, and when puncturing, require that the position of pin puncture is very accurate, in order to avoid needle pierces blood vessel, breast chamber, subarachnoid space, simultaneously after puncture completes, if connect subject needs of patients to go to toilet, so transfusion pole must be carried, inconvenience very, and easily cause the backflow of blood, affect normal infusion, also cause larger discomfort to patient simultaneously, the local of the most health of patient of Neurology Department can be trembleed, therefore existing puncture needle is when transfusion, vibration due to patient can cause it to come off, affect normal infusion.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of Neurology Department and infuses special puncture needle, this device is when infusing, can effectively avoid because the vibration of patient and the puncture needle that causes comes off, this device is very convenient to patient and is gone to toilet simultaneously, can avoid blood backflow preferably.
For solving the problem, this utility model adopts following technical scheme:
Neurology Department is infused a special puncture needle, and comprise puncture shank, the diameter of described puncture shank is 0.5-1mm, described puncture shank front end has sharp end, the taper seat of described sharp end is provided with sprue, described puncture shank is provided with secondary channels near described sharp end position, described secondary channels is provided with two or more, described puncture needle rod rear end is connected with current limiting component, described current limiting component comprises flexible pipe, impeller flow control valve and transfusion capsule ball, described puncture shank end is set in described flexible pipe, described flexible pipe is through described impeller flow control valve, it is connected with described transfusion capsule ball through end, described flexible pipe and transfusion capsule ball are for being flexibly connected, described flexible pipe has bellows segment near described puncture shank place, described flexible pipe front end face is bonded with tampon, described flexible pipe is provided with skid resistant course near front end face position.
As preferably technical scheme, the shaft of above-mentioned puncture shank is provided with scale, by this scale, what be convenient to that new hand medical personnel grasp puncture shank thrusts the degree of depth, avoids thrusting dark or piercing blood vessel.
As preferably technical scheme, above-mentioned tampon is compression cotton wool, traditional cotton wool is comparatively loose, therefore it does not have comparatively fixing shape, simultaneously its poor-performing of sucking blood, and compress cotton wool there is comparatively fixing profile, there is stronger shape of sucking blood simultaneously, when avoiding treatment patients, garter position is hemorrhage.
As preferably technical scheme, above-mentioned secondary channels is circle hole shape, and described secondary channels, around described puncture shank, can accelerate transfusion speed by secondary channels.
The beneficial effects of the utility model are: this device is in the process of transfusion, tampon tightly props up and punctures mouth place, blood outflow and affect sight line when avoiding puncture, this device is provided with a utricule simultaneously, transfusion capsule ball is pulled up during normal infusion, flexible pipe docking common transfusion pipe, during as gone to toilet or temporarily not infuse, by regulating impeller flow control valve, flexible pipe is sealed up, then fluid delivery apparatus is extracted, hose connection upper transfusion capsule ball, supspend transfusion, then at this moment effectively can avoid blood backflow, the a small amount of blood of instant outflow, blood is by the absorption of tampon, facilitate patient largely to go to toilet, this device is provided with skid resistant course simultaneously, contrast prior art, skid resistant course can convenient adhesive plaster fixing, avoid because of movable, this device being come off during transfusion, the structure of this device is comparatively simple simultaneously, use more for convenience, be applicable to promoting the use of.
Accompanying drawing explanation
In order to be illustrated more clearly in this utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Consult Fig. 1, Fig. 1 is the enlarged diagram of this device, Neurology Department is infused a special puncture needle, and comprise puncture shank 1, the diameter of described puncture shank is 0.5-1mm, described puncture shank 1 front end has sharp end 101, the taper seat of described sharp end 101 is provided with sprue 111, described puncture shank 1 is provided with secondary channels 112 near described sharp end 101 position, described secondary channels 112 is provided with two or more, described puncture shank 1 rear end is connected with current limiting component, described current limiting component comprises flexible pipe 2, impeller flow control valve 3 and transfusion capsule ball 4, described puncture shank 1 end is set in described flexible pipe 2, described flexible pipe 2 is through described impeller flow control valve 3, it is connected with described transfusion capsule ball 4 through end, described flexible pipe 2 and transfusion capsule ball 4 are for being flexibly connected, described flexible pipe 2 has bellows segment 201 near described puncture shank 1 place, short by the ripple arranged, add flexibility, make to use during puncture more convenient, described flexible pipe 2 front end face is bonded with tampon 202, and described flexible pipe 2 is provided with skid resistant course 203 near front end face position.
