Description

Pen cap anti-falling device suitable for automatic injector

Technical Field

The utility model relates to a pen cap anticreep device especially relates to a pen cap anticreep device suitable for automatic syringe.

Background

An automatic injector is a medical device for assisting in pre-filling injection preparation, namely a pre-filled Syringe (PFS) filled with liquid medicine for injection. Because the protein concentration of the liquid medicine in the pre-encapsulation injection preparation is higher, the viscosity of the liquid medicine is usually higher, the higher viscosity leads to direct injection of the pre-encapsulation injection preparation, and the liquid medicine can difficultly enter subcutaneous tissues of patients, so that an automatic injector device is usually required to assist the pre-encapsulation injection preparation to inject, and the automatic injector contains a power spring which can provide injection power for injecting the liquid medicine.

When the pen cap of the automatic injector is pulled out, the rubber needle cap of the PFS is clamped by the special structure in the pen cap, so that the rubber needle cap of the PFS is pulled out together when the pen cap is pulled out, and a needle head of the PFS is exposed.

In the case of daily use, the patient can pull out the automatic injector pen cap by mistake due to unfamiliarity with the apparatus; in addition, the automatic injector pen cap may fall off due to factors such as transportation or shaking during storage. No matter which mode causes the pen cap to fall off, the PFS needle in the automatic injector is exposed in the air, so that the liquid medicine is polluted after contacting with the air (the liquid medicine is exposed in the air, and the pen cap is not used for the purpose even if being immediately installed again), the waste of the liquid medicine is caused by the accident, or medical risks are caused to patients due to the pollution of the liquid medicine.

In view of the above-mentioned drawbacks, the present inventors have made active research and innovation to create a pen cap anti-disengaging device for an automatic injector, which has industrial application value.

Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

The cap retaining device for an automatic injector as shown in fig. 1 to 3 is distinguished by the following features: the anti-drop label strip 1 can prevent the external force from directly acting on the joint of the pen cap 8 and the injector, and the accidental loosening can not occur. Meanwhile, in consideration of the normal use period, the pen cap 8 can be pulled out under stress, and the separation reserved notch 2 is arranged on the anti-falling label 1, so that the separation is facilitated. Considering the convenience of manufacture, the anti-drop label 1 comprises a bearing layer 3, an adhesive layer 4 is arranged at the bottom of the bearing layer 3, and a marking layer 5 is arranged at the upper part of the bearing layer 3. Of course, from the integration point of view, the back adhesive can also be directly arranged at the bottom of the bearing layer 3.

Combine the utility model discloses an embodiment of preferred sees, considers traditional cap for brush 8 to adopt cup joint connection or swivelling joint, can realize in the normal use anticreep label 1 tear the separation smoothly, and the separation is reserved incision 2 and is the incision that the mirror image distributes on anticreep label 1, and anticreep label 1 that is located between the incision constitutes narrow limit 6. In this way, thanks to the presence of the configuration of the narrow sides 6, adequate connectivity is satisfied, without sudden cracking when subjected to external undue stresses. Meanwhile, multiple comparison tests show that the narrow edge 6 is 1-3 cm wide, so that smooth tearing during use can be achieved, and accidental cracking during transportation can be avoided.

Further, in order to enable the narrow edge 6 to tear when being subjected to proper external force stimulation during the separation of the pen cap 8, the angle of the separation reservation cut 2 is adopted to be 90-150 degrees. Of course, in view of smooth separation of the separation allowance slit 2 in actual use, the angle of the separation allowance slit 2 may be generally 100 degrees.

In terms of actual manufacturing, the bearing layer 3 is a paper layer, the thickness of the paper layer is 0.1 to 0.3 mm, and the label layer 5 is a fluorescent spray coating layer. Or the marking layer 5 is an ink printing layer, so that the requirements of different processing technologies are met. Certainly, in order to facilitate the user to know in time that the pen cap 8 can not be opened easily when not in use, avoid appearing polluting and scrapping, warning signs 7 can also be distributed on the labeling layer 5.

The working principle of the utility model is as follows:

the anti-slip label 1 is applied to the junction of the cap 8 and the auto-injector, preferably with the narrow edge 6 flush with the junction. Thus, the user can directly see the warning words 7, and the opening is avoided. In the time of in-service use, no matter extract or rotatory cap for brush 8, to letting the narrow limit 6 atress fracture to let the separation of anticreep tag 1 reserve incision 2 fracture, realize the separation and use. Meanwhile, the separated anti-drop label strip 1 cannot be bonded for the second time, is placed for the second time and is not used properly, so that the anti-drop label strip is convenient to identify, and the use safety is improved.

Through foretell expression of characters and combination of the attached drawing can be seen, adopt the utility model discloses afterwards, possess following advantage:

5. The whole structure is simple, and the manufacture and the use are easy.
