Description

Anti-acupuncture artery hemostix

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to prevent acupuncture artery hemostix.

Background

The collection of arterial blood gas is a common nursing operation in clinical work, and in order to perform blood gas analysis, the blood gas analysis is often used for monitoring respiratory failure and acid-base imbalance and adjusting mechanical ventilation parameters, analyzing curative effect and judging prognosis. At present, medical personnel carry out the arterial blood gas to the patient and gather the back, need seal the needle tubing, prevent that the air from getting into the needle tubing and influencing the qi and blood analysis result, prick the plug with the syringe needle usually, take off the syringe needle again and spin up the seat cap and make the needle tubing totally enclosed, at this in-process, the plug of fixed needle point drops easily, lead to medical personnel to be stabbed by the syringe needle, because contain patient's blood in the syringe needle, there is certain pathogenic bacterium probably, thereby lead to medical personnel to take place the occupation and expose, infect the germ, threaten medical personnel life safety.

SUMMERY OF THE UTILITY MODEL

The utility model provides a prevent acupuncture artery hemostix, easy and simple to handle, simple structure prevents that medical personnel from taking place the acupuncture wound to the hemostix destroyer in-process to can avoid pricking the medical staff who tests blood.

The utility model adopts the technical proposal that: the utility model provides a prevent acupuncture artery hemostix, includes syringe needle, cylinder to and piston and the core bar of setting in the cylinder, still includes the sleeve, telescopic one end is provided with the sealing plug, and the sealing plug is made by elastic material, the syringe needle passes from the sealing plug, telescopic other end setting is outside the cylinder, and the sleeve can slide to the syringe needle direction by the cylinder relatively to make and form the airtight space that can hold the syringe needle completely between sleeve and the cylinder. Be provided with stop gear between sleeve and the cylinder for the restriction sleeve slips from the cylinder, stop gear is including setting up the draw-in groove at the cylinder outer wall and setting up the internal thread at the sleeve inner wall, and draw-in groove and internal thread can match and screw or unscrew.

The part of the needle which penetrates through the sealing plug to be exposed is provided with a needle sheath.

The outer wall of the needle cylinder is marked with scales, and the needle cylinder and the sleeve are both made of transparent materials.

The thickness of the sealing plug is 0.5CM, and the width of the clamping groove is 0.2 CM.

Furthermore, the rotating direction between the clamping groove and the internal thread is consistent with the rotating direction of unscrewing the threaded connection between the needle head and the needle cylinder.

After gathering arterial blood, promote the sleeve to the syringe needle direction, when the draw-in groove looks butt of telescopic internal thread and cylinder, screw draw-in groove and internal thread for the syringe needle is in the airtight space that sleeve and cylinder formed completely, and during the sealing plug was pricked to the needle point, the seal of arterial hemostix was guaranteed, avoided blood specimen and air contact, also avoided medical staff to be stabbed by the syringe needle simultaneously. Because the direction of rotation of thread rotation between draw-in groove, internal thread and syringe needle, cylinder is unanimous, during the chemical examination blood measuring person can directly press the screw direction together to unscrew sleeve and syringe needle, gets the blood chemical examination, and medical staff need not direct contact syringe needle at this in-process, avoids being stabbed.

The utility model has the advantages that: the setting of sleeve and sealing plug makes can avoid syringe needle and external direct contact with the syringe needle protection of hemostix in an airtight space after gathering arterial blood, and in addition, sleeve and syringe needle can be twisted off simultaneously, and the operation is convenient, avoids medical staff to take place the acupuncture and injures when taking a blood sample, chemical examination blood or ruining the shape hemostix, guarantees medical staff's life safety, prevents that the occupation from exposing.

Detailed Description

Example 1

As shown in fig. 1 and 2, the anti-needle-prick arterial blood collector comprises a needle 2, a needle cylinder 5, a piston 7 and a core rod 9 which are arranged in the needle cylinder 5, and a sleeve 6, wherein one end of the sleeve 6 is provided with a sealing plug 3, the sealing plug 3 is made of an elastic material, the needle 2 passes through the sealing plug 3, and the part of the needle 2 which passes through the sealing plug 3 and is exposed is provided with a needle 2 sheath 1. The outer wall of the needle cylinder 5 is marked with scales, and both the needle cylinder 5 and the sleeve 6 are made of transparent materials. The other end of the sleeve 6 is arranged outside the needle cylinder 5, and the sleeve 6 can slide towards the needle head 2 relative to the needle cylinder 5, so that a closed space which can completely contain the needle head 2 is formed between the sleeve 6 and the needle cylinder 5. Be provided with stop gear between sleeve 6 and the cylinder 5 for 6 landing from the cylinder 5 of restriction sleeve, stop gear is including setting up draw-in groove 4 and the internal thread 8 of setting at 6 inner walls of sleeve in the 5 outer walls of cylinder, and draw-in groove 4 and internal thread 8 can match and screw or unscrew. Preferably, the thickness of the sealing plug 3 is 0.5CM, and the width of the clamping groove 4 is 0.2 CM.

After gathering arterial blood, promote sleeve 6 to syringe needle 2 direction, when the internal thread 8 of sleeve 6 and draw-in groove 4 looks butt of cylinder 5, screw draw-in groove 4 and internal thread 8 for syringe needle 2 is in the airtight space that sleeve 6 and cylinder 5 formed completely, avoids blood sample and air contact, also avoids medical staff and syringe needle 2 direct contact simultaneously, prevents to be stabbed by syringe needle 2.

Example 2

Example 2 is a further modification of example 1, as shown in figures 1 and 2.

In the prior art, the needle seat of the needle 2 of the hemostix is in threaded connection with the needle cylinder 5, and the needle 2 can be unscrewed from the needle cylinder 5 by rotating the needle 2, so that the destruction treatment of the needle 2 is facilitated. In embodiment 1, the internal thread 8 of the sleeve 6 can rotate in match with the locking slot 4 of the needle cylinder 5, and in this embodiment, the internal thread 8 and the locking slot 4 are further modified so that the rotation direction is consistent with the rotation direction between the needle head 2 and the needle cylinder 5. On the other hand, when the sleeve 6 slides towards the needle head 2 until the needle tip part of the needle head 2 is completely inserted into the sealing plug 3 of the sleeve 6, the internal thread 8 of the sleeve 6 is just abutted and screwed with the clamping groove 4 of the needle cylinder 5. At the moment, the needle point is fixed in the sealing plug 3, the needle head 2 and the sleeve 6 form a whole body due to the friction resistance between the needle point and the sealing plug 3, the needle head 2 is driven to rotate when the sleeve 6 is screwed again, the threaded connection between the needle seat of the needle head 2 and the needle cylinder 5 is unscrewed, and the needle head 2 is unscrewed while the sleeve 6 is unscrewed. After having gathered the blood sample, medical staff receives the blood sample and need carry out the chemical examination to it, twists the sleeve 6 this moment and just can twist off syringe needle 2 also in the lump, gets the blood chemical examination, need not twist syringe needle 2 again after taking off sleeve 6, avoids inspection personnel direct contact syringe needle 2, prevents to be stabbed by syringe needle 2.

The above description is only a specific embodiment of the present invention, and is not used to limit the protection scope of the present invention, for those of ordinary skill in the art to which the present invention pertains, without departing from the concept of the present invention, a plurality of simple deductions or replacements can be made, which should be regarded as belonging to the protection scope of the present invention.
