Abstract
The utility model relates to a multifunctional needle, comprising a needle base, a needle peduncle and a needle neck, wherein the needle base and the needle neck are arranged with a blood observing window, a filter is arranged between the needle neck and the needle peduncle, the filter is composed of a upper cap provided with a stop opening, a lower cap and a filter net located between the upper cap and the lower cap. The blood window could help the medical staff directly discover whether the blood feedback phenomenon has happed, to prevent the blood from sucked into the inner cavity of the injector to cause contamination, the injector could be used continuously, to save the devices. The particle with a diameter bigger than 15um could be effectively prevented from entering the medicine liquid by the filter, to decrease contamination and guarantee the safety of the human body.
Description
(1) technical field
This utility model relates to a kind of medical apparatus, particularly a kind of multi-functional syringe needle.
(2) background technology
At present, dilution and suction solution use syringe needle No. 16 always in the medical domain clinical nursing activity, and this syringe needle is made up of the pin stalk and the needle stand that have needle point, and has the access way that is interconnected.But, has following shortcoming during use: because the bottle stopper of medicine powder all is to be made by rubber, this plug fragility is bigger, some finding of naked eye and the invisible rubber particle of naked eyes can occur when with the puncture of No. 16 syringe needles, also sneaking into of unavoidable various microgranules in preparation medicament process.Thereby, carry these impurity in the medicinal liquid secretly and may be imported in the human body serious harm patient's health together.
In addition, after medical personnel stung people's muscle with syringe needle, piston was drawn in examination, checked whether intravasation of syringe needle, as when taking out piston, when loseing the blood extraction, know that then syringe needle in blood vessel, can push medicinal liquid, extract out if any blood, then should change the injection site, this moment, the syringe internal organs were contaminated, caused cross infection easily.
(3) summary of the invention
This utility model provides a kind of syringe needle that has blood hagioscope and defecator in order to solve the defective that above-mentioned prior art exists.
This utility model is realized by following measure: a kind of multi-functional syringe needle, comprise needle stand, have pin stalk, the pin neck of needle point, it is characterized in that: in needle stand and pin neck, the blood hagioscope is installed, between pin neck and the pin stalk defecator is installed, described defecator is made up of the loam cake that has seam, lower cover and the drainage screen between loam cake, lower cover.
The beneficial effects of the utility model:
1. the blood hagioscope can help medical personnel's direct discovery when operation whether to have the blood back phenomenon, does not make in the inner chamber of blood inhalation syringe, pollutes, and syringe can continue to use, and saves equipment.
2. because the effect of defecator can prevent effectively that diameter from entering in the medicinal liquid greater than the 15um microgranule, reduce once more and pollute, the safety of guaranteeing to infuse human body.
(4) description of drawings
Below in conjunction with drawings and Examples this utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
1 pin stalk among the figure, 2 loam cakes, 3 drainage screens, 4 lower covers, 5 pin necks, 6 blood hagioscopes, 7 needle stands.
(5) specific embodiment
As shown in Figure 1, a kind of multi-functional syringe needle, comprise needle stand 7, have pin stalk 1, the pin neck 5 of needle point, 5 li blood hagioscope 6 is installed at needle stand 7 and pin neck, between pin neck 5 and the pin stalk 1 defecator is installed, defecator is to be sealed and matched and along sticking into one with a kind of heart line pressure, between loam cake 2, the lower cover 4 drainage screen 3 to be installed by the loam cake 2 that has seam, lower cover 4.The through hole of loam cake 2, lower cover 4 and pin stalk 1, pin neck 5 match.
Described pin stalk 1, needle point adopt steel to make, and drainage screen 3 adopts polypropylene to make.Blood hagioscope 6, needle stand 7, loam cake 2, lower cover 4 adopt nontoxic transparent material to make.It is identical with original syringe needle that this syringe needle uses.
Claims (1)
1. multi-functional syringe needle, comprise needle stand (7), have pin stalk (1), the pin neck (5) of needle point, it is characterized in that: blood hagioscope (6) is installed at needle stand (7) and pin neck (5) lining, between pin neck (5) and the pin stalk (1) defecator is installed, described defecator is by the loam cake that has seam (2), lower cover (4) and be positioned at that drainage screen (3) between loam cake (2), the lower cover (4) forms.
