Description

Technical Field

[0001] The utility model belongs to the technical field of medical sponge heads, and in particular relates to a polyolefin adsorption cotton head for multiple-joint detection of secretions. Background Art

[0002] At present, the absorbent cotton head is formed by pressing several layers of foam. For the columnar absorbent cotton head, the direction of each layer of foam in the existing absorbent cotton head is along the height direction of the absorbent cotton head, and several layers of foam are pressed together along the width direction of the absorbent cotton head, which is easy to spread out.

[0003] The adsorption cotton head lacks supporting force. When the tester (such as a drug addict) is extracting saliva, the tester's teeth can easily bite off the adsorption cotton head and swallow the test sponge. Utility Model Content

[0004] The problem to be solved by the utility model is: how to increase the supporting force of the adsorption cotton head.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

The cotton head body is a columnar structure with a bottom surface and a side surface. The cotton head body is formed by crimping several layers of polyolefin foam along the height direction of the cotton head body. At least two supporting grooves penetrating the side surface of the cotton head body are arranged on the side surface of the cotton head body.

[0007] Furthermore, the cotton head body is a cylindrical structure.

[0008] Furthermore, the number of the supporting grooves is two, three, four, five or six, and all the supporting grooves are evenly distributed along the circumference of the cotton head body.

[0009] Furthermore, the support groove is an arc-shaped support groove, and the cross section of the arc-shaped support groove is an arc.

[0010] Furthermore, the supporting groove is a right-angle groove, and the angle at the vertex of the cross section of the right-angle groove is a right angle.

[0011] Furthermore, the supporting groove is a rectangular grid-shaped groove, which is composed of a plurality of longitudinal grooves parallel to the axis of the cotton head body and a plurality of transverse grooves penetrating the longitudinal grooves.

[0012] Furthermore, multiple longitudinal grooves are evenly distributed longitudinally on the side of the cotton head body at equal intervals, and multiple transverse grooves are evenly distributed transversely on the side of the cotton head body at equal intervals, and the length direction of each transverse groove is consistent with the curvature of the side of the corresponding cotton head body.

[0013] Furthermore, the supporting groove is a diamond grid-like groove, and the diamond grid-like groove is composed of a plurality of left-inclined grooves and a plurality of right-inclined grooves that interpenetrate and intersect each other.

[0014] Furthermore, a plurality of left-inclined grooves are evenly distributed at equal intervals on the side surface of the cotton head body, and the left-inclined grooves are inclined to the left relative to the horizontal plane.

[0015] Furthermore, a plurality of right-inclined grooves are evenly distributed at equal intervals on the side surface of the cotton head body, and the right-inclined grooves are inclined to the right relative to the horizontal plane.
