Problems solved by technology

[0004] Although plastic is elastic and can deform under stress to reduce oral discomfort, plastic is generally difficult to degrade, and oral swabs are disposable consumables and cannot be reused. This will inevitably lead to a serious increase in plastic products and plastic pollution. Therefore, there is room for improvement

preparation example 1-3

[0043] A fluff comprising the following components:

[0044] Polyhydroxybutyrate, polylactic acid, polycaprolactone, polybutylene succinate, antioxidant.

[0045] In Preparation Examples 1-3, see Table 2 for the specific input amount of each raw material.

[0046] Table 2

[0047]

[0048] In the preparation example 1-3, the preparation method of fluff is as follows:

[0049] Put polyhydroxybutyrate, polylactic acid, polycaprolactone, polybutylene succinate, and antioxidant into a stirred tank at a rotating speed of 120r / min and stir for 2min to obtain a premix.

[0050] Put the homogeneous mixture into an extruder, extrude at a temperature of 150° C., extrude and granulate to obtain composite polymer particles.

[0051] The composite polymer particles are put into the electrospinning equipment, and the fluff filaments are obtained through the electrospinning process, wherein the needle aperture is 0.2mm, the spinning voltage is 16kV, and the receiving distance is 18cm.

Embodiment 1

[0064] A degradable disposable oral swab for sampling, including a handle. One end away from the handle is fixedly connected with a connecting rod. The connecting rod is in the shape of a circular tube. The end of the connecting rod away from the handle is closed. The closed end of the connecting rod is hemispherical.

[0065] The connecting rod is provided with a sampling head, the sampling head is composed of a number of hairs, one end of the hairs is fixedly connected to the outer wall of the connecting rod and the other end extends away from the direction of the connecting rod, each hair and the connecting rod at the connection point with the hairs The cut surfaces form an included angle of 88-90°.

[0066] The outer wall of the broken section is marked with a red marking line.

[0067] When using, hold the handle, insert the head into one side of the oral cavity, and scrape it against the inner wall of the oral cavity for 15-20 times, then go to the other side of the ora...

Embodiment 2

[0073] A degradable disposable oral swab for sampling. Compared with Example 1, the only difference is:

[0074] In this embodiment, the fluff of Preparation Example 2 is used.

Abstract

The invention relates to the field of oral swabs, and particularly discloses a degradable disposable sampling oral swab. The degradable disposable sampling oral cavity swab comprises a handle, a connecting rod fixedly connected with the handle and a sampling head arranged on the connecting rod, the sampling head is composed of a plurality of villus, one end of the villus is fixedly connected to the connecting rod, and the other end of the villus extends in the direction away from the connecting rod; the fluff is prepared from the following components in parts by mass: 10 to 11 parts of polyhydroxybutyrate; 15 to 16 parts of polylactic acid; 30 to 32 parts of polycaprolactone; 3 to 4 parts of poly (butylene succinate); 0.1 to 0.15 part of an antioxidant; the handle and the connecting rod are both made of degradable plastics. The method has the advantage of reducing plastic pollution.

Description

technical field [0001] The invention relates to the field of oral swabs, in particular to a degradable disposable oral swab for sampling. Background technique [0002] With the development of the medical level, the technology of human body sampling and analysis of the disease is becoming more and more mature. Human oral cavity sampling is a common sampling method, usually through oral swabs. When sampling, the oral swabs are inserted into the side of the mouth. Scrape up and down the inner wall mucosa for 15-20 times. When sampling, the oral swab is close to the inner wall mucosa of the oral cavity to ensure that the oral swab can pick up the exfoliated cells of the oral mucosa. When sampling, both sides of the oral cavity need to be scraped multiple times Sampling is carried out in the same way, and after the sampling is completed, the oral swab is placed in a test tube for storage. [0003] Therefore, the oral swab needs to exert a certain force during the sampling proces...
