More particularly, the present invention relates to a swap for sampling a biological sample by a multi-component injection molding method, And the head part are integrally molded by injection molding to improve the adhesion of the head part and the head part is made of a synthetic resin material capable of being injected with antimicrobial property to suppress the generation of particles and harmful bacteria to improve hygiene performance And more particularly, to a sample swab using a multi-component injection molding method and a manufacturing method thereof.

In general, a swab is a tool for collecting samples such as blood, saliva, or stool of a subject in order to perform various tests according to a subject's examination. That is, a swab is used to collect mucus or tissue from a person's nose, mouth, ear, etc., and is also used for sampling to diagnose pathogen or virus infection in a hospital.

Typically, a swap is generally referred to as a swab, and is provided with a head made of wood or a synthetic resin material for collecting a sample of surface material at one end of the stick, so that it is absorbed by a head made of a surface material during sample collection. In other words, the head of the swab may be formed by winding cotton, nylon, polyester, etc., or by applying an adhesive to the tip of the stick and then using nylon particles with electrical force And a hooking method that catches up.

As described above, since the head portion to be sampled is made of cotton or nylon, it is contaminated by the mucous membrane of the nose and the oral mucous membrane which samples the sample by particles generated from the surface or nylon itself, There is a problem that can be caused.

In addition, there is a problem that the adhesion performance of the nylon material or the nylon material to be adhered to the stick in the form of a cotton is deteriorated and the lifetime is short due to easy detachment by external impact.

In recent years, a synthetic resin having an absorbing performance while suppressing the generation of particles has been developed, and a technique of sticking to a stick to manufacture by swap has been developed and used.

In the conventional swap manufacturing method, the stick portion and the head portion are separately manufactured, the stick is applied to the head with the adhesive, and then the head portion is inserted and adhered.

However, in the conventional swap, stick and head are manufactured respectively and then a bonding operation is performed using an adhesive. By sticking and sticking a stick and a head together in a bonding process and performing a bonding operation, There was a delay problem.

In addition, there is a problem in that hygienic performance is lowered due to increased possibility of contamination of the head part by inserting contaminants into the stick when inserting the stick in the state of gripping the head, which is a material to be absorbed in the adhering step.

In the swap manufacturing method of the related art, when the head of the material to be absorbed is adhered to the stick, a part of the adhesive material is absorbed into the head, so that the adhesive material is hardened in the head and the absorption performance of the head is lowered. There is a problem that the defective rate is increased due to contamination of itself.

In addition, the swap manufactured in the prior art has a problem in that an adhesive material exists between the head and the stick, and after the sample is collected, various reagents or various tests that respond to the specimen depending on the type of the test are performed. And thus the reliability of the inspection is deteriorated.
