Description

A kind of arterial puncture needle

Technical field

The utility model is related to a kind of medicine equipment and in particular to a kind of arterial puncture needle.

Background technology

At present, arteriopuncture has been widely used in medical field, can gather arterial blood mark using arteriopuncture This, enter Mobile state blood gas analysis, electrolyte and arterial pressure detection etc., to the rescue of patient, treatment and the state of an illness to urgent patient Dynamic observation have great importance, and arterial puncture needle is one of requisite apparatus in arteriopuncture.Arteriopuncture Pin is draw point to be inserted in blood vessel treat that blood is in that beating shape is gushed out it was demonstrated that draw point is inserted in blood vessel it really when using Afterwards, then by draw point detach from indwelling casing tube, then reuse blood, the blood pressure that testing equipment detects in indwelling casing tube, or Blood collection in indwelling casing tube is chemically examined further to other instruments.Existing arteriopuncture needle construction is simpler, There is following defect: on the one hand, during draw point is inserted into blood vessel, have the other end from draw point for the blood during use Gush out；On the other hand, during draw point detaches indwelling casing tube, also have substantial amounts of blood and enter indwelling casing tube, then from staying The other end putting sleeve pipe flows out, and during whole arteriopuncture, can slattern substantial amounts of blood, operating environment of pollution, lead to disease People produces frightened mood, and sb.'s illness took a turn for the worse because of excessive blood loss to even result in patient.Therefore, needing a kind of operating process badly will not be a large amount of The arterial puncture needle lost blood.

Content of the invention

The utility model is in order to make up the deficiencies in the prior art, there is provided one kind is rational in infrastructure, convenient and practical and operates The arterial puncture needle of Cheng Buhui massive blood loss, solves problems of the prior art.

The technical solution of the utility model is as follows:

A kind of arterial puncture needle, including a draw point and the indwelling casing tube being sheathed on outside draw point, the syringe needle of draw point is from indwelling set The front end of pipe passes, and is provided with the transparent blood storing capsule of one and draw point intracavity inter-connection in the rear end of draw point, in the capsule of transparent blood storing capsule Wall is provided with an air-vent, and the outer wall outwardly convex of the described indwelling casing tube front end mouth of pipe forms a circular arc and arches upward portion, It is provided with a funnelform socket in the rear end of indwelling casing tube, be provided with an extruding sacculus, described extruding in the postmedian of indwelling casing tube The inner chamber of sacculus is connected with the tube chamber of its upper and lower ends indwelling casing tube respectively.

The beneficial effects of the utility model are: this arterial puncture needle, and structure is simple, rationally distributed, easy to operate；Transparent storage Haematodocha can store the blood gushed out in draw point, prevents the blood gushed out from polluting external environment condition；Air-vent on transparent blood storing capsule, Transparent blood storing capsule can be made to connect with atmosphere outside, be easy to blood and gush out in transparent blood storing capsule.Need to control blood stream When going out, blocking air-vent with finger can make to form the space of a closing in transparent blood storing capsule, stop the further of blood Gush out.When draw point is detached indwelling casing tube, pinch extruding sacculus with finger, close its interior inner chamber, stop blood from indwelling The socket ejection of sleeve pipe, the waste of anti-Hemostatic Oral Liquid and pollution external environment condition, it is to avoid patient produces frightened mood, is suitable to be widely popularized Application.

Brief description

Below in conjunction with the accompanying drawings the utility model is further described.

Fig. 1 is perspective view of the present utility model.

Fig. 2 is longitudinal cross section structure diagram of the present utility model.

In figure, 1, draw point, 2, indwelling casing tube, 3, transparent blood storing capsule, 4, air-vent, 5, arc arch upward portion, 6, socket, 7, squeeze Pressure ball capsule, 8, inner chamber.

Specific embodiment

For the technical characterstic of this programme can be clearly described, below by specific embodiment, and combine its accompanying drawing, to this reality It is described in detail with new.

As shown in figs. 1-2, this arterial puncture needle, including a draw point 1 and the indwelling casing tube 2 being sheathed on outside draw point 1, draw point 1 syringe needle passes from the front end of indwelling casing tube 2, is provided with the transparent blood storing capsule of one and draw point 1 intracavity inter-connection in the rear end of draw point 1 3, an air-vent 4 is provided with the cyst wall of transparent blood storing capsule 3, the outer wall outwardly convex of the described indwelling casing tube 2 front end mouth of pipe is formed One circular arc arches upward portion 5, is provided with a funnelform socket 6 in the rear end of indwelling casing tube 2, in indwelling casing tube 2 after Portion is provided with an extruding sacculus 7, and the inner chamber 8 of described extruding sacculus 7 is connected with the tube chamber of its upper and lower ends indwelling casing tube 2 respectively.

Draw point 1 is interspersed in indwelling casing tube 2, the syringe needle of draw point 1 passes from the front end of indwelling casing tube 2, finds arterial blood accurately Pipe position, this arteriopuncture is needled in blood vessel, when the blood occurring in transparent blood storing capsule 3 gushing out in beating shape, due to The setting of transparent blood storing capsule 3, makes the blood storage gushed out it is therefore prevented that blood contaminated operation platform etc. is grasped in this transparent blood storing capsule 3 Make environment.Blood is in that beating shape is gushed out, and illustrates that the syringe needle of draw point 1 has been inserted in arteries, is then blocked with finger transparent Air-vent 4 on blood storing capsule 3, makes to form the space of a closing in transparent blood storing capsule 3, has prevented gushing out further of blood, Prevent the waste of blood, it is to avoid patient causes the generation that sb.'s illness took a turn for the worse because of excessive blood loss.

Blocked after air-vent 4 with finger, indwelling casing tube 2 is pushed ahead, its front end is advanced to inside arteries；By Outer wall in the indwelling casing tube 2 front end mouth of pipe is provided with a circular arc and arches upward portion 5, so, in the mistake of propulsion indwelling casing tube 2 Cheng Zhong, the mouth of pipe of indwelling casing tube 2 will not stab the inwall of blood vessel, and indwelling casing tube 2 slip in intravascular can be made more smooth； Arc arch upward portion 5 design moreover it is possible to prevent indwelling casing tube 2 from skidding off from blood vessel, play the effect of stable indwelling casing tube 2.

Indwelling casing tube 2 is advanced to after Ink vessel transfusing, draw point 1 is extracted out slowly from indwelling casing tube 2, when the pin of draw point 1 After head passes through extruding sacculus 7, pinch extruding sacculus 7 with finger, close its interior inner chamber 8, even if by draw point 1 from indwelling casing tube 2 Middle extraction, there will not be blood and spray the waste it is therefore prevented that blood from the socket 6 of indwelling casing tube 2, it is to avoid blood pollution operation Environment is it is therefore prevented that patient produces frightened mood.After end of operation, you can detection means etc. is inserted on this socket 6, carry out follow-up Operation.

The utility model does not describe part in detail, is the known technology of those skilled in the art of the present technique.Finally illustrate, with Upper embodiment only in order to the technical solution of the utility model to be described and unrestricted, although with reference to preferred embodiment to the utility model It has been described in detail, it will be understood by those within the art that, the technical solution of the utility model can be repaiied Change or equivalent, the objective without deviating from technical solutions of the utility model and scope, it all should be covered in the utility model Right in the middle of.
