The specific embodiment
The circlip type safety needle guard of the band sheath shown in Fig. 1～7 includes syringe needle 1, is arranged with plastic cement shell 2 on syringe needle 1.Simultaneously, be provided with the syringe needle through hole of coming in and going out for syringe needle 1 in a side of plastic cement shell 2, the opposite side of plastic cement shell 2 is provided with the syringe connectivity port.Be provided with the spacing jump ring of syringe needle in the plastic cement shell 2, the spacing jump ring of this syringe needle is provided with lock hole 3 near the syringe needle through hole, and the spacing jump ring of syringe needle is provided with position-arresting hole 4 near place, syringe connectivity port.Front end needle point 14 at syringe needle 1 is provided with the stop bit parts, and its unusual part is: the end that described plastic cement shell 2 is provided with the syringe needle through hole is provided with connection tube, and described extension is provided with the needle tubing sheath component.Moreover, better spacing for spacing jump ring is carried out, prevent that it from coming off in plastic cement shell 2, be provided with parting bead 5 at the two ends of plastic cement shell 2, the spacing jump ring of syringe needle is between parting bead 5.
In conjunction with this utility model one preferred implementation, the needle tubing sheath component includes backplate 6, is extended with on the backplate 6 to protect needle guard 7.Simultaneously, be provided with connecting hole on backplate 6, connecting hole is connected with described connection tube.Like this, in syringe needle 1 was postponed the whole process of plastic cement shell 2 retraction, needle point 14 positions can be in fully to be protected in the needle guard 7.
Simultaneously, the spacing jump ring of the syringe needle that this utility model adopted its be configured to the concave shape jump ring.Specifically, this concave shape jump ring includes jump ring base plate 8, and described jump ring base plate 8 is provided with preceding locking plate 9 near a side of syringe needle through hole, offers lock hole 3 on the preceding locking plate 9.Corresponding with it is that jump ring base plate 8 is provided with back locking plate 10 near a side of syringe connectivity port, offers position-arresting hole 4 on the back locking plate 10.And, match formation needle point 14 spatial accommodations between the locking plate 9, back locking plate 10 and plastic cement shell 2 before described.
Further, consider the correct work of lock hole 3, allow lock hole 3 can produce certain deformation, described preceding locking plate 9 locking plate 10 direction bendings backward, preceding locking plate 9 is circular-arc.And, in order to improve the smooth and easy degree of deformation, around lock hole 3, being distributed with stuck point, these stuck points are the v-shaped openings 11 that prolong lock hole 3 circumferential external diffusions.Simultaneously, consider that v-shaped openings 11 is stressed even when syringe needle 1 motion, these v-shaped openings 11 are for to be crossing distribution around lock hole 3 circumference.
As Fig. 4, shown in Figure 5, for the ease of qualification to needle position, position ring 12 till the described stop bit parts, the aperture of described position-arresting ring 12 is greater than the aperture of position-arresting hole 4 with lock hole 3.Certainly, consider the easy making process of whole syringe needle 1, also the stop bit parts can be changed into expansion mouth 13, the aperture of order expansion mouth 13 is greater than the aperture of position-arresting hole 4 and the aperture of lock hole 3.
Be used for seeing in conjunction with actual making of the present utility model, in existing injection, often need the medicament that some are liquid to mix, form together injection, the therefore process that exists a liquid to shift behind a kind of mixed solution with pulverous medicament.Such as, will be in the safe needle guard of protective-cover type syringe needle 1 usefulness in Fig. 1 state and insert in the container that holds liquid pharmaceutical and extract liquid.Inject the container that holds Powdered medicament afterwards.Extracting mixed liquor at last injects.During this period, because the existence of needle tubing sheath component the drawn needle pipe racks can not occur and go out container bottle material beyond the Great Wall, guaranteed injection safety.
Again further, in case after having carried predetermined close to patient, shortly will be when patient extracts out on one's body syringe needle 1.User advances plastic cement shell 2 toward the injection site, move to patient's skin limit.Afterwards, continue to extract syringe needle 1 out, make needle point 14 from patient skin, bounce back and enter in the plastic cement shell 2.Simultaneously, in this process, because the needle tubing of syringe needle 1 is outside equipped with and protects needle guard 7, the injection back incidental pollutant of needle tubing institute possibility are all in protecting needle guard 7, particularly needle point 14 is protected needle guard 7 fully and is taken in, the unexpected situation that pierces through user can in the process of taking in, not occur, realize first anti-pollution insurance.
Then, as shown in Figure 6: before the stop bit parts of needle point 14 run into behind the locking plate 9, because the aperture of position-arresting ring 12 or the expansion mouthful 13 stop bit parts that constitute is greater than the aperture of lock hole 3, needle point 14 can apply certain power to lock hole 3 and the stuck point that distributes thereof when retraction, the stuck point that makes v-shaped openings 11 constitute irreversible deformation occurs towards needle point 14 retraction direction.This deformation directly causes the aperture of lock hole 3 further to diminish specifically, props up lock hole 3 even needle point 14 moves ahead once more, also can't pass therethrough, and has played the effect of the locking that travels forward.
Then, constitute in needle point 14 spatial accommodations between locking plate 9 and the back locking plate 10 before needle point 14 further retracts to, finish taking in of needle point 14.In conjunction with Fig. 7, after needle point 14 is received into needle point 14 spatial accommodations, because the aperture of position-arresting ring 12 or the expansion mouthful 13 stop bit parts that constitute is greater than the aperture of position-arresting hole 4, needle point 14 can't further retreat, the abnormal phenomena that 2 slippages of plastic cement shell can not occur has been guaranteed the safe and effective of syringe needle 1 especially needle point 14 taken in.
By above-mentioned character express also in conjunction with the accompanying drawings as can be seen, after adopting this utility model, by cooperating of plastic cement shell and needle tubing sheath component, after finishing injection, at first can effectively isolate the incidental pollutant of needle tubing, and after syringe is finished using, by preceding locking plate and back cooperating between the locking plate, to syringe needle particularly the sealing of carrying out a safety of its tip portion isolate, can guarantee effectively that the syringe needle that has used can not pollute external environment condition.What is more important can prevent that used syringe needle accident from piercing through personnel, stops the pathophoresis approach of this danger.Simultaneously, this utility model simple structure is convenient to extensive manufacturing, is worthy to be popularized.
