Technical field
The present invention relates to the guard shield of a kind of distal end at least covering administration device before using administration device.
Background technology
In this application, term distally refers to from the part that the hands of user is farthest, and term distally refers to from the part that the hands of user is nearest. Similarly, in this application, term " distal direction " refers to administration direction, and namely towards the direction of patient, and term " proximal direction " refers to and is administered direction in opposite direction, namely leaves the direction of patient.
Administration device is generally used for some technical fields (such as, for instance field of medicaments), for such as by medicine or sprayed by spraying equipment or injected by injection device medicine is supplied patient. For this, the distal end of administration device can be provided with a formula and install pin (stakedneedle) or ozzle or luer connection, thus allowing to arrange assembly, and such as nozzle assembly or needle assembly.
In this application, " stake formula installs pin " refers to the pin being fixed on the tip of injection device with glued or other proper method (such as, for instance make the tip of syringe shrink after heating) around pin.
At field of medicaments, injection device (than such as with or stake formula the syringe of pin of needle assembly on pin or luer syringe is installed) be generally supplied to terminal user with needle shield: it practice, pin is until must keep aseptic and needs from being likely to pollution from environment when using. And, when injection device has pin, terminal user must also from unexpected needle stick injury. And, when refilling syringe, needle shield guarantees sealing, it is to avoid content runs off in storage process.

The present invention is not only applied to needle shield but also be applied to tip cap. In this application, except as otherwise noted, term " guard shield " is generally used for " needle shield " or for " tip cap ".
These guard shields or at least part of of these guard shields are generally made up of elastomeric material, described elastomeric material is such as thermoplastic elastomer (TPE), such as rubber, and described guard shield is such as fastened in the distal end of administration device on the assembling line of industrial pharmaceutical company. For this point, the distal end of administration device generally includes needle stand, and pin can be such as fastened on needle stand by gluing, and guard shield is such as bonded on needle stand removedly by rubbing.
When being automatically assemblied in the distal end of administration device by needle shield on assembling line, one of problem encountered is in that needle shield always can not be placed on the end of administration device fully. Especially, it may occur however that when needle shield is arranged on the end of administration device, needle shield is not directed along the longitudinal axis of administration device. As a result, the longitudinal axis of needle shield not overlapping with the longitudinal axis of administration device (confounded), needle shield tilts relative to the end of administration device. Owing to guard shield is generally made up of rubber, and rubber is the material quite glued when normal use, and guard shield is accidentally bonded on the needle stand of administration device in unsuitable position. Additionally, be likely to be difficult to remove it when using administration device.
Another problem the fact that due to guard shield poor location produced is difficult to be positioned at guard shield in the hole of operation dish, particularly when utilizing the automation equipment of assembling line: this destruction that may result in manufacturing line and emergency shutdown.
And, when administration device include formula pin is installed, the tip of pin can penetrate the elastomeric material forming guard shield: this phenomenon can be very problematic for using subsequently by the pin of the particle contamination from described elastomeric material. Additionally, the tip of pin is likely to expose the wall of guard shield, this will cause obvious sealing and aseptic problem. Finally, due to the poor location of guard shield and make guard shield be likely to be bent, pin is likely to be broken itself. Fig. 1 a-1d illustrates above-mentioned problem of the prior art. These figures show that according to such as those automatic industrial processes occurred in the assembling line of drugmaker, the needle shield 1 of prior art is fastened on the step on the needle stand 2 of the such as distal end of the administration device of syringe 3.

In fig 1 a, the pin 6 at the close distal end place being fixed on syringe 3, chamber 5 of needle shield 1. Can be seen that from Fig. 1 a, in the process that needle shield 1 is close to pin 6, the longitudinal axis A of needle shield 1 is not parallel with the longitudinal axis B of syringe 3. Fig. 1 b shows, by oscillation device, needle shield 1 is positioned at the step on the end of syringe 3. After this step, needle shield should be parallel with the longitudinal axis A of administration device with B, but due to the viscosity of elastomer, needle shield 1 is maintained at improper position, and wherein the longitudinal axis A of needle shield 1 and administration device 3 and B are not parallel. As a result, the tip 7 of pin 6 contacts with the elastomeric walls 4 of needle shield 1. As illustrated in figure 1 c, the distal force shown in arrow F of Fig. 1 c is then applied on needle shield 1, to be assemblied on the end of administration device by needle shield. In figure 1 c, under the effect of the distal force being applied on needle shield 1, needle shield 1 is parallel with the respective axis of administration device 3 now, but this causes that pin 6 bends. In Fig. 1 d, it is shown that the assembling when the distal force release being applied on needle shield 1. The longitudinal axis of pin is taken back by the resilience force of pin 6 substantially along the direction of the longitudinal axis of syringe 3, but this active force forces the needle shield 1 longitudinal axis relative to syringe 3.
As Fig. 1 d is expressly shown, the elastomeric walls 4 of needle shield 1 is bonded on needle stand 2 in incorrect position. This phenomenon makes to be difficult to remove needle shield when using syringe. And, as Fig. 1 d is expressly shown, the tip 7 of pin 6 has penetrated the elastomeric walls 4 of needle shield. The tip 7 of pin 6 is likely to be polluted by the elastomer particles from wall 4.
Accordingly, it would be desirable to the guard shield of a kind of end for covering administration device, described guard shield allows to be properly mounted on the needle stand of administration device end by guard shield, installs especially by those automation equipments being used in assembling line.
