Boring machine of negative-pressure conduction lapping material

Abstract

The invention relates to a punching machine for wrapping materials by vacuum drainage, which comprises a base (1). The middle part of the base (1) is provided with a sliding chute (11); one end of the base (1) is provided with a wrapping material compact device (2), while the other end is provided with a punching device (3) capable of sliding along the sliding chute (11); and a punching needle (31) on the punching device (3) can pass through the wrapping material inside the compact device (2). The punching machine overcomes the defects that the prior manual hand drill has low efficiency and high labor intensity, and that the wrapping material is damaged seriously so as to cause medical malpractice easily. The punching machine has the advantages of simple structure, convenient use, and great improvement on working efficiency and product quality.

Description

technical field [0001] The invention relates to a negative pressure drainage packaging material punching machine. Background technique [0002] Negative pressure drainage refers to placing a drainage tube with wrapped materials in the wound and cavity of the human body that needs to be drained, and using negative pressure to drain blood clots, necrotic tissue fragments, and viscous pus through the drainage tube. in vitro. The wrapping material therein is soft in texture and fully contacts with the drainage cavity. The drainage tube is placed in the hole of the wrapping material and does not directly contact the drainage cavity. The drained material is first sucked into the wrapping material, shaped and decomposed, then introduced into the drainage tube, and then sucked away by high negative pressure. However, it is very difficult to evenly punch small holes in the existing wrapping materials which are soft in texture. People generally use manual hand drills to punch holes....

AI Technical Summary

Problems solved by technology

However, it is very difficult to evenly punch small holes in the existing wrapping materials which are soft in texture. People generally use manual hand drills to punch holes. This manual method is inefficient, labor-intensive, and the holes punched are uneven. Therefore, the damage of the wrapping material is large (and easy to generate debris), and the waste is serious. If this type of wrapping material is directly used for patients, it is easy to cause medical accidents, such as the drainage tube and the wrapping material are disengaged, and the small pieces on the wrapping material are broken. Debris is left in the human body, etc.
