Abstract
The utility model belonging to the field of medical apparatus relates to a puncturing device which can judge the type of the punctured artery and vein automatically. The utility model comprises an injector and a puncturing needle base. The injector is provided with a compatibility thin polymeric membrane made of high elasticity organism. The injector or the puncturing needle base of the utility model is provided with the membrane sign. One surface of the membrane contacts the blood directly and will not deforms evidently under the working of the vein blood pressure; but the membrane will deforms a lot and forms a balloon under the working of the artery blood pressure. The medical staff can judge the type of the punctured artery or vein through the form of the balloon. The utility model with simple structure, striking sign, safe and reliable operation can avoid the medical accident effectively.
Description
Technical field
This utility model belongs to medical instruments field, relate to a kind of can differentiate automatically the sting device of quiet, the tremulous pulse type code of the blood vessel that thrusts.
Background technology
In clinical practice, medical personnel often will carry out the puncture of artery and vein, in some cases, require puncture to carry out in vein, if mistake is thrust in the arteries, should obtain correcting, such as inserting of central venous catheter at once.Other situations require puncture to carry out in tremulous pulse again, if thrust vein, need to correct at once, inspect by random samples as arterial blood gas.And existing sting device as shown in Figure 1, do not have quiet, tremulous pulse type that any sign can help medical personnel to judge to thrust blood vessel, and medical personnel can only carry out various operations by experience, easily cause malpractice.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, and indicates eye-catchingly, and safe and reliable can differentiate the sting device that thrusts vascular group automatically.
The technical solution adopted in the utility model: a kind ofly can differentiate the sting device that thrusts vascular group automatically, comprise syringe, Paracentesis needle holder, it is high resiliency biocompatibility macromolecule thin film that syringe is provided with a material.Syringe is provided with an aperture, and thin film and the syringe outer wall mode of connecting firmly are bonding or heat seal welding or mechanical connection.Syringe can be ordinary syringe, also can be to insert seal wire with syringe, vim and vigour examination at random syringe.Thin film is arranged on the Paracentesis needle holder, and needle stand is provided with an aperture.Thin film and the Paracentesis needle holder outer wall mode of connecting firmly are bonding or heat seal welding or mechanical connection.Thin film is arranged on the straight peen joint of Y type Paracentesis needle holder, and needle stand is provided with an aperture.Thin film and the Paracentesis needle holder straight peen joint outer wall mode of connecting firmly are bonding or heat seal welding or mechanical connection.
Syringe of the present utility model or Paracentesis needle holder are provided with the thin film sign, the one side of thin film directly contacts with blood, and thin film tangible distortion can not take place under venopressor effect, but under the effect of arteriotony, big distortion can take place and form balloon, whether medical personnel can form by balloon, judge the artery and vein type of thrusting blood vessel, this utility model is simple in structure, indicate eye-catchingly, safe and reliable, effectively avoid malpractice.

The specific embodiment
Embodiment 1
Consult Fig. 2, shown in Figure 3, a kind ofly can differentiate the sting device that thrusts vascular group automatically, comprise syringe 1, Paracentesis needle holder 2, thin film 3, its syringe 1 is provided with the thin film 3 that a high resiliency biocompatible polymer material is made, by binding agent 4 it is bonded on syringe 1 outer wall, and makes a call to an aperture on syringe 1 outer wall thin film 3 is directly contacted with blood, the thin film 3 at aperture place is under vein pressure (low pressure) effect, since the intensity of material itself, and do not have any tangible distortion; But in arterial pressure (high pressure) effect down, the thin film pressure is above distortion of materials pressure, obvious large deformation can take place and forms balloon.Whether medical personnel can have balloon to produce by observing, and can accurately judge and thrust blood vessel artery and vein type.Thin film 3 is also heat sealable to be welded on syringe 1 outer wall.
Embodiment 2
Consult Fig. 4, shown in Figure 5, thin film 3 of the present utility model also can adopt mechanical connecting mode, is installed on syringe 1 outer wall as adopting connecting piece 5.All the other structures are with embodiment 1.
Syringe 1 of the present utility model can be existing ordinary syringe, also can be the existing seal wire of inserting and inspects by random samples with syringe, vim and vigour and use syringe.
Consult Fig. 6, shown in Figure 7, thin film 3 of the present utility model also can be arranged on the Paracentesis needle holder 2, and on needle stand 2, make a call to an aperture thin film 3 is directly contacted with blood, the thin film 3 at aperture place can adopt bonding agent 4 to be bonded on the needle stand 2, also can adopt heat seal welding or mechanical connecting mode to fix.
Embodiment 4
Consult Fig. 8, shown in Figure 9, present embodiment Paracentesis needle holder 2 ' for to insert the Y type Paracentesis needle holder that seal wire is used, Paracentesis needle holder 2 ' straight peen mouth is connected with syringe 1, plagiocephaly is used for inserting seal wire, thin film 3 sign is bonded in needle stand straight peen joint.All the other structures are with embodiment 3.
