Protective sampling swab for large animals

Abstract

The invention discloses a protective sampling swab for large animals in the technical field of medical instruments. The protective sampling swab comprises an outer shell, an inner shell and a samplingswab. The outer shell is a transparent hollow cylindrical tube, a sampling end is folded towards the central axis to form a hemisphere, and a star-shaped one-way valve opening structure is arranged;the inner shell is a transparent hollow cylindrical tube, the middle part of the inner shell is sleeved in the outer shell, the tail section is provided with a funnel-shaped buckle. Before the swab isin use, the sampling end of the inner shell is sleeved in the outer shell. The sampling swab comprises a swab rod, a swab head and a push-pull rod, and the middle part of the swab rod is sleeved in the inner shell; the swab head is fixed at the front end of the swab rod, and the retraction state and the extension state are switched under the push-pull action of the push-pull rod; with a double-layer protective shell structure, sterile sampling is practically realized, the sampling result is more accurate; and, the problem of artificial uterine effusion cannot be solved.

Description

technical field [0001] The invention belongs to the technical field of medical appliances, in particular to a protective sampling swab for large animals. Background technique [0002] Endometritis is considered to be the most important reproductive disease of mares and dairy cows at present, which can lead to infertility, low reproductive rate, and reduced milk production of female animals. In addition, its treatment is expensive, which brings huge economic losses to the entire industry. At present, there are few domestic literatures on sampling methods in the uterus or upper respiratory tract of large animals, especially for equine animals in my country, whose medical level is relatively backward. Compared with some developed countries, we lack more advanced diagnosis and treatment measures. The entire industry The development is severely restricted, and the welfare of equine animals is difficult to be guaranteed. There are many basic research works that need to be improved,...

AI Technical Summary

Problems solved by technology

[0006] ①The outside of the swab is unprotected and easily contaminated;

[0007] ②The length of the swab rod is not enough to extend into the uterus or nasopharynx of large animals (such as equine animals, cattle, etc.);

[0008] ③ It is inconvenient to transport after independent swab sampling;

[0009] ④ Cotton swabs have poor water absorption and low sample collection efficiency;

[0010] ⑤ The absorbent cotton on the head of the swab may be prone to flocs;

[0011] ⑥ Sampling methods are more complicated (such as syringes, hoses, vas deferens, etc.)

[0012] Therefore, in order to solve the problem of difficult sampling of deep structures such as the reproductive tract and upper respiratory tract of female animals (mainly equines and cattle), a protective sampling swab was designed.
