Description
Technical field
This utility model relates to a kind of scalp acupuncture, particularly relates to a kind of anti-stab scalp acupuncture.
Background technology
Pricking wound is the main route of transmission of infecting blood diseases such as hepatitis B, hepatitis C and acquired immune deficiency syndrome (AIDS), thereby and the potential danger that is infected by pricking wound medical worker initiation blood source just is on the rise.The medical worker's who is caused occupational exposure causes the potential danger that infects in the blood source and just is on the rise.The Center for Disease Control (CDC) data shows, existing 57 people are made a definite diagnosis and infected HIV (human immunodeficiency virus) (Human Immunodeficiency Virus) in 2000 end of the year U.S. medical workers, stab infection 48 people that cause by skin, account for 84.2%.And show through the investigation and analysis of World Health Organization (WHO), the annual number that infects fatal disease because of unsafe pin operation reaches 2,100,000 more than, cause great misery and misfortune for infected person, and caused huge medical expenses, increased the weight of the financial burden of society and family.Show that according to the U.S. disease Disease Control and Prevention Center statistics generation of using safer medical device can avoid the dash of 62%-68% to hinder is very necessary so develop safer band pin medical device product.
The scalp acupuncture that uses clinically causes its security performance not good enough owing to before the inserting needle protective sleeve is abandoned at present.The patent No. is 200420038952.4; in the utility model of patent disposable safe type venous transfusion scalp acupuncture by name; a kind of disposable safe type venous transfusion scalp acupuncture is disclosed; comprise that syringe needle, the syringe needle pin wing, protective sleeve constitute; end in protective sleeve is provided with the sterilization tampon; be provided with the strip mouth on the wall of protective sleeve back segment, the syringe needle pin wing stretches out in the strip mouth, establishes butterfly tail in protective sleeve tail end bottom side.Though this disposable safe type venous transfusion scalp acupuncture has solved protective sleeve and the isolating problem of syringe needle, when scalp acupuncture used, protective sleeve and syringe needle did not have fixture, and its empennage design is unfavorable for puncture.
Summary of the invention
The weak point of this utility model in the background technology designs a kind of hour hands medicated cap and syringe needle of using and can fix and anti-stab scalp acupuncture easy to use.
The anti-stab scalp acupuncture of this utility model, it comprises syringe needle, needle stand and pin medicated cap, needle stand one end is fixed with syringe needle, needle stand one side is extended the pin wing, the pin medicated cap is the plastic tube of one section hollow, be set in needle stand and be fixed with an end of syringe needle, the corresponding pin wing of described pin medicated cap is provided with guide groove, described guide groove is equipped with the draw-in groove of the corresponding pin wing near the pin port of export and guide groove end, the draw-in groove of guide groove end is provided with grab near the pin port of export, a projection is extended to the pin port of export in this grab and guide groove joint, and when infusing, the pin wing of scalp acupuncture is placed in the guide groove by projection; When carrying out venous transfusion, the pin wing of scalp acupuncture snaps in the draw-in groove of the guide groove pin port of export; When the scalp acupuncture transfusion finished, the pin wing snapped in the terminal draw-in groove grab that is provided with of guide groove.
The draw-in groove width of the described guide groove pin port of export and end is than the little 0-0.05mm of pin wing width.When the draw-in groove width than the pin wing hour, can utilize the elastic deformation of plastics, the pin wing is snapped in the draw-in groove, what guarantee simultaneously that the pin wing can be firm is placed in the draw-in groove.
The grab width that is provided with in the draw-in groove of described guide groove end is 0.3-0.8mm.When the scalp acupuncture transfusion finishes, the artificial draw-in groove that firmly the pin wing is snapped in the guide groove end, the grab that is provided with in the draw-in groove can prevent that the pin wing slip from going out draw-in groove like this, thereby guarantees that syringe needle is fixed in the pin medicated cap.
Described grab and guide groove joint are triangle or circular arc to the extended projection of the pin port of export, are preferably circular arc.When not infusing, the pin wing of scalp acupuncture is spacing by this projection, with the holding of the pin wing in guide groove.
Leave the gap between described projection and guide groove, the width in this gap is less than pin wing thickness.When scalp acupuncture did not use like this, the pin wing can not pass the gap, thereby made the needle point of syringe needle expose the pin medicated cap; And when scalp acupuncture uses, utilize the elastic deformation of plastics, and firmly artificial, make the pin wing pass this gap, promote forward along guide groove.
When the pin wing of described scalp acupuncture snapped in the draw-in groove of guide groove end, the needle point of syringe needle did not expose outside the pin medicated cap.
Be provided with ear-flap with the opposing side of guide groove on the described pin medicated cap outer wall.When intravenous infusion with winged needle set finished, this ear-flap can be used as the operation impetus in the needle retraction pin medicated cap, makes this operation easier.
Described guide groove end is provided with pin flyer lead inlet, introducing port to the guide groove width between the terminal draw-in groove of guide groove less than pin wing thickness, prevent that the pin wing from not skidding off the pin medicated cap from introducing port before using.
Described syringe needle is the Z type, and wherein the folding surface of Z type syringe needle is vertical with the pin wing.Can lower the height of syringe needle and needle stand junction and skin like this, allow syringe needle more press close to skin.
When scalp acupuncture did not use, the pin wing of scalp acupuncture was placed in the guide groove by projection, prevented that syringe needle from skidding off.When carrying out venous transfusion, the ear-flap of proficiency fixing head sword-shaped needle, the one hand-held firmly pin wing, firmly the pin wing is passed from the gap between guide groove and projection, promote the pin wing forward along guide groove then, the pin wing is pushed into the draw-in groove of the guide groove pin port of export, and the pin wing is snapped in this draw-in groove, guarantee that fix in use by syringe needle and pin medicated cap for scalp acupuncture.When the scalp acupuncture transfusion finishes, proficiency is ear-flap fixedly, the one hand-held firmly pin wing, the pin wing is withdrawed from the draw-in groove of the guide groove pin port of export, return to the draw-in groove position of guide groove end, firmly the pin wing is snapped in this draw-in groove, the grab that is provided with in the draw-in groove can prevent that the pin wing slip from going out draw-in groove, syringe needle was fixed in the pin medicated cap when thereby the assurance intravenous infusion with winged needle set was intact, thereby avoided accidental needle sticks to hinder.
In a word, use anti-stab scalp acupuncture of the present utility model, simple in structure, easy to operate.Scalp acupuncture is when infusing, and syringe needle and pin medicated cap can be fixed, and when transfusion finished, scalp acupuncture was firmly fixed in the draw-in groove of pin medicated cap guide groove end, has avoided the accidental needle sticks wound.Simultaneously, scalp acupuncture uses and need not be put in the sharp instrument box, only needs to concentrate place then that sent for disposal get final product, can reduce the expenditure of medical institutions' purchase dash box, and treat the spending that is caused after can reducing injury to personnel.
