Embodiment 1

[0042] Such as figure 1 and 2 Shown: a storage tube for endocrine samples, including a tube body 1-1 with both ends open. The head end of the tube body 1-1 is provided with a liquid inlet valve head 1-2. The tail end of -1 is provided with a sealing rubber plug 1-3, and the liquid inlet valve head 1-2 has a built-in one-way valve that allows liquid to enter the inside of the pipe body 1-1. It should be noted that the liquid inlet valve head 1-2 2. It is connected to the pipe body 1-1 in a detachable way, such as a screw connection. In addition, the sealing problem needs to be considered during the screw connection to prevent the liquid inside the pipe body 1-1 from passing through this part. It is foreseeable that the above-mentioned problems can be avoided by setting gaskets.

[0043] The sample storage tube of this embodiment can store the endocrine liquid extracted from the patient's body, and the endocrine liquid enters the inside of the tube body 1-1 from the liquid inl...

Embodiment 2

[0046] Such as image 3 Shown: a storage tube for endocrine samples, including a tube body 1-1 with both ends open. The head end of the tube body 1-1 is provided with a liquid inlet valve head 1-2. The tail end of -1 is provided with a sealing rubber plug 1-3, and the liquid inlet valve head 1-2 has a built-in one-way valve that allows liquid to enter the inside of the pipe body 1-1, and the tail end of the pipe body 1-1 The outer wall is provided with limiting ears 1-4.

[0047] Compared with Example 1, the sample storage tube in this embodiment differs only in the setting of the stopper ears 1-4, and its position in the sampling box is fixed through the stopper ears 1-4. Since the sample storage tube is in the sampling box There are many ways to fix the position. Therefore, the limiting ear 1-4 is not an essential feature. The specific function of the limiting ear 1-4 needs to be described in detail in the following embodiments in conjunction with other structures.

Embodiment 3

[0049] Such as Figure 4 Shown: an endocrine sample sampling box, including a box body 2-1 and three sample storage tubes 1 in Example 1 installed on the box body 2-1, and three installation channels 2 are arranged on the box body 2-1 -2, the installation channel 2-2 is set through the box body 2-1 along the length direction of the box body 2-1, and three installation channels 2-2 are set around the center line of the box body 2-1.

[0050] The above structure is similar to the magazine in a revolver. The sample storage tube 1 is put into the installation channel 2-2 by filling. After the sample storage tube 1 is loaded into the installation channel 2-2, the following structural design is adopted Realize the fixation of the sample storage tube 1 in the box body 2-1.

[0051] The tail end of the box body 2-1 is screwed with a back cover 2-3, and the back cover 2-3 is provided with three through holes 2-4. When the back cover 2-3 is completely screwed into the back end of the b...

Abstract

The invention provides an internal secretion sample storage tube, sampling box and negative pressure suction sampling device. The sample storage tube comprises a tube body of which the two ends are opened; a liquid inlet valve head is arranged at the head end of the tube body; a sealing rubber plug is arranged at the tail end of the tube body; the sampling box comprises a box body and N pieces of sample storage tubes installed on the box body; and N pieces of mounting channels are arranged on the box body; The sampling device comprises a suction sampling barrel and the above sampling box, wherein the suction sampling barrel comprises a sampling barrel, a negative pressure component and a puncture component. The internal secretion sample negative pressure suction sampling device is of an ammunition loading type structure, a sampling operation can be carried out after the independent sampling box is loaded during use, working position switching of a plurality of sample storage tubes and butt joint of the sample storage tubes with the puncture component and the negative pressure component can be achieved through a simple rotating and pushing-pulling operation, and low-operation-amount collection of multiple endocrine samples is realized.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an endocrine sample storage tube, a sampling box and a negative pressure suction sampling device. Background technique [0002] Endocrine refers to the phenomenon that the substances produced by the body tissues are directly secreted into the blood and body fluids without going through the catheter. A secretory form in which hormones produced by secreting cells directly enter body fluids, and use body fluids as a medium to produce effects on target cells. The endocrine system refers to a large system of the humoral regulation system composed of the secretions of all endocrine glands and hormone endocrine glands in the body, and it is closely connected with the central nervous system. Endocrine disorders often refer to female endocrine disorders, and female patients account for the vast majority. Endocrine system diseases: both men and women can see, such as hyperthyroid...
