Embodiment 1

[0041] see Figure 1-9 , according to an embodiment of the present invention, a split-type corrupted biological material extractor includes a block 1, and a cavity 2 is opened in the block 1. It is worth noting that the cavity 2 mentioned here is a four-sided sealed cavity. One end of the cavity 2 is provided with an outlet 3, and the inner wall of the cavity 2 is provided with a first push rod 4 on both sides of the outlet 3, and a replacement door 5 is provided on one side of the cavity 2, One side of the replacement door 5 is located in the cavity 2 and is provided with a U-shaped clamping plate 6, and the U-shaped clamping plate 6 is connected with a transmission rod 8 through a connecting plate 7, and the transmission rod 8 moves through the In the cavity 2, the transmission rod 8 is fixedly provided with a handle 9 at one end outside the cavity 2, the handle 9 is for conveniently pulling the transmission rod 8, and the handle 9 is set on the transmission rod 8 The first...

Embodiment 2

[0044] see figure 1 and Figure 10 , for the box 1, a disposable sterile cotton 35 is provided outside the box 1 around the outlet 3. A telescopic protective sleeve 36 is provided under the handle 9 and outside the transmission rod 8 , and the telescopic protective sleeve 36 includes a plurality of cylinders that are closed and socketed with each other.

[0045] Through the above solution of the present invention, by arranging the disposable sterile cotton 35, the contamination of the part where the block 1 contacts with the body is reduced, and by arranging the telescopic protective cover 36, it is possible to reduce related personnel being pinched by the first spring 10.

Embodiment 3

[0047] see figure 1 and figure 2 , for the handle bar 24, the handle bar 24 is provided with a protective baffle 37. The outer wall of the block 1 is provided with a finger-pressing plate 38 through a movable shaft, and a finger-pressing plate 38 is provided under the finger-pressing plate 38 to be in contact with the pressing rod 34 through an extension rod. One side of the pressing rod 34 is located in the channel 25 and is fixed with a horizontal plate 39 , and the horizontal plate 39 is connected to the inner wall of the channel 25 through the fourth spring 40 . The acupressure plate 38 is provided with an arc-shaped protection ring 41 , and the two ends of the arc-shaped protection ring 41 are respectively fixed on the square 1 and the handle bar 24 .

[0048] Through the above scheme of the present invention, by setting the protective baffle 37, the relevant personnel will not be accidentally injured by the handle when taking the sample, and by setting the acupressure...

Abstract

The invention discloses a split type spoiled biological sample extractor comprising a block, wherein the block is internally provided with a cavity, one end of the cavity is provided with an outlet, first ejector rods are arranged on both sides of the outlet on the inner wall of the cavity, one side of the cavity is provided with a replacement door, one side of the replacement door is provided with a U-shaped card board in the cavity, the U-shaped card board is connected with a transmission rod by a connection plate, the transmission rod movably runs through the cavity, the transmission rod isfixedly provided with a handle at one end out of the cavity, a first spring is sleeved on the transmission rod under the handle, both ends of the first spring are fixedly connected to the handle andthe block, and an extraction mechanism is disposed in the U-shaped card board. The split type spoiled biological sample extractor has the beneficial effect that the spoiled organisms can be effectively and quickly sampled, the obtained samples are clear in layers with no need of processing again and are convenient for observation, and incisions to the body can be effectively reduced to ensure theintegrity of the body.

Description

technical field [0001] The invention relates to the field of specimen extraction, in particular to a split-type extractor for spoiled biological specimens. Background technique [0002] Inspection material is the inspection material used by forensic doctors in case analysis and identification. It is an important physical evidence to clarify the truth of the incident and investigate the case. There are many kinds of test materials, and the test materials referred to in forensic science can be roughly divided into in vitro test materials and in vivo test materials. The former mainly refers to the test materials that are distributed on site without being absorbed, digested and metabolized by organisms. Different test materials have different sources, properties and compositions, and the pretreatment methods and testing methods to be used are also different. The analysis results obtained by testing different types of test materials are of great significance in forensic identifi...
