Description

Technical Field

[0001] The invention belongs to the technical field of medical device production equipment and relates to a feeding device, in particular to a feeding device for an injection needle with a protective cover. Background Art

[0002] Existing syringe sheaths are generally cylindrical and protect the needle tube. The sheath needs to be removed during injection and put on again after the injection is completed. However, one end of the sheath is open and it is not easy to put on the needle tube, which poses a safety problem of medical staff being stabbed by the needle tube. The sheath is also easy to fall off and there is a risk of secondary use.

[0003] In view of the above-mentioned problems, people have designed a syringe protection device and applied for a patent [application number: 201721617145.1; authorization announcement number: CN208481817U], which includes a syringe protection cover and a fixed seat, the syringe protection cover includes a needle tube protection cover and a syringe barrel protection cover seamlessly connected to the needle tube protection cover, the fixed seat includes a sealing base and an injection connector which faces away from the sealing base and forms a cylindrical protrusion, one side of the sealing base is connected to the top side of the syringe protection cover through a connecting element, a hollow connecting hole is formed at the connection between the injection connector and the sealing base, and the connecting hole forms a fitting toothed groove circumferentially on the inner wall of the injection connector facing away from the syringe protection cover, and the fitting toothed groove and the outer conical connector at the top of the syringe fit each other.

[0004] When the above-mentioned syringe protection device is used, the fixed seat is covered on the needle seat of the injection needle, and the injection needle seat is provided with a cylindrical sheath. The sheath is taken off, and after the injection is completed, the syringe protection sleeve is pulled to cover the needle tube. The syringe protection sleeve is provided with a tongue depressor that is clamped to the needle tube to prevent the needle tube from escaping from the syringe protection sleeve. The use is convenient and safe. Now the injection needle will be covered with a sheath and the protective sleeve will be connected to the needle seat, and then the injection needle with the protective sleeve will be placed on the blister packaging machine for packaging. However, because the injection needle with the protective sleeve has an irregular shape, the direction of the protective sleeve and the injection needle cannot be controlled. Therefore, the workers place the injection needle with the protective sleeve on the blister packaging machine with a relatively consistent direction. The work efficiency is low, time-consuming and labor-intensive, and errors are inevitable in manual operation, resulting in errors in the direction of each injection needle with the protective sleeve, which will affect subsequent packaging and result in poor product consistency.

Each limit groove 1 48 and each buckle 1 50 are arranged one by one, and each pair of limit grooves 1 48 and buckles 1 50 forms a material placement slot on the carrier 2 5. A support plate three 51 is fixedly connected to the side of the carrier four 13, and a portion of the support plate three 51 higher than the top surface of the carrier four 13 has a row of limit grooves two 52 with the notches facing upwards. A support plate four 53 is fixedly connected to the side of the carrier four 13 relative to the support plate three 51, and a portion of the support plate four 53 higher than the top surface of the carrier two 5 has a row of buckles two 54 with the buckles facing upwards. The limit grooves two 52 and the buckles two 54 are arranged one by one opposite to each other, and each pair of limit grooves two 52 and buckles two 54 form a material placement groove on the carrier four 13. The limiting groove 1 48 and the limiting groove 2 52 are used to snap the needle seat of the injection needle into, and the buckle 1 50 and the buckle 2 54 are used to snap the sheath of the injection needle into, so that the injection needle is firmly positioned on the carrier 2 5 and the carrier 4 13, and the support plate 1 47 and the support plate 2 49 prevent the carrier 2 5 from interfering with the protective cover. After the protective cover of each injection needle on the carrier 2 5 is moved by the swing lever 1 42, the dumping process is smooth. Similarly, the support plate 3 51 and the support part 4 prevent the carrier 4 13 from interfering with the protective cover. After the protective cover of each injection needle on the carrier 4 13 is moved by the swing lever 2 44, the dumping process is smooth.
