Rolling pressing type drainage package materials hole generator

Abstract

The invention relates to the technical field of medical apparatus, in particular to a rolling pressing type drainage package materials hole generator. The rolling pressing type drainage package materials hole generator comprises a handle frame, a frame handle, a slide groove frame, a needle bed plate, screw fastening rotary buttons, a side support, protruding bars, supporting columns, a rolling depression wheel, a rotary shaft, shaft sleeves, a through hole, a supporting plate, slide grooves, needle top caps, springs, needle rods, needle heads, assembly holes and a depression bar, wherein the slide groove frame is a metal frame which is horizontally arranged, two side frames, namely, the upper side frame and the back side frame are respectively provided with one slide groove, the needle bed plate is arranged under the slide groove frame, each angle of the needle bed plate is fixed with the supporting columns, and an annular shaft sleeve is sleeved on each end, between the end of the rolling depression wheel and the slide grooves, of the rotating shaft. Compared with the prior art, the distribution of holes formed in package materials by the rolling depression type hole generator is more even.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a rolling-type drainage wrapping material hole generator. Background technique [0002] During the negative pressure drainage process, it is necessary to have uniformly sized and evenly distributed holes on the surface of the wrapping material to facilitate the absorption of the drained material. Existing technicians usually drill holes by manual hand drilling. This manual method is inefficient and labor-intensive. Large, and the punched holes are not uniform, and the damage to the material is also large. [0003] Patent No. 200910061116.5 In order to solve the above problems, two toothed pressure plates are used to sandwich the wrapping material, so that the wrapping material has wave-like undulations, and then a punching needle is inserted from the side to make holes of uniform size. But in fact this technical scheme has following defective: [0004] 1. Since each per...

Problems solved by technology

[0004] 1. Since each perforating needle has to pass through the walls of the multi-layered wrapping material in turn during the one-time punching process and the process of passing through the wrapping material with undulations, during the puncture process, the thickness of the first layer of material The time for the wall of the hole to be rubbed by the wall of the puncture needle is the longest, and the time for the wall of the hole of the last material to be rubbed by the wall of the puncture needle is the shortest, and the size of the hole is proportional to the degree of friction of the wall of the hole. Therefore, with the above technical scheme The size of the holes punched on the same wrapping material is not uniform. The uneven size of the holes will lead to uneven drainage speed in different parts of the wound, which will affect the recovery progress of the wound.

[0005] 2. Since the punching device needs to be manually reset after each punching is completed, the punching efficiency is not high
