Description

Technical Field

[0001] The utility model relates to the technical field of allopregnanolone quantitative dripping, in particular to an allopregnanolone quantitative dripping device. Background Art

[0002] Allopregnanolone is an endogenous steroidal metabolite and a derivative of progesterone. It has low biological activity in the human body, but its concentration changes under certain physiological and pathological conditions, such as pregnancy, stress, depression, etc. Allopregnanolone has certain neuroprotective effects, which may be related to the regulation of neurotransmitter release, anti-oxidation, anti-inflammatory and other mechanisms. In addition, allopregnanolone may also affect cognitive function, mood and behavior. Allopregnanolone is an organic compound with the molecular formula CHO2. Allopregnanolone is a progesterone with anesthetic, hypnotic and sedative effects.

[0003] Currently, in the field of treatment of postpartum depression, quantitative injection of allopregnanolone has become a more effective treatment method. Before injecting allopregnanolone, allopregnanolone needs to be quantitatively added or extracted into a syringe. Currently, quantitative addition or extraction of allopregnanolone is usually done manually, which increases the intensity of manual labor.

[0004] Therefore, a quantitative dripping device for allopregnanolone is proposed. Utility Model Content

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0010] A sleeve is fixed on the outer wall of the L-shaped strip, a connecting strip is connected inside the sleeve, and a connecting ring is fixed at one end of the connecting strip;

[0011] A quantitative tube is connected inside the connecting ring;

[0012] A dripping tube is installed at the bottom of the quantitative tube, and a valve body is installed on the outer wall of the dripping tube.

[0021] One end of the compression spring is fixed to the auxiliary plate, and the other end of the compression spring is fixed to the connecting ring.

[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] The utility model adds allopregnanolone into the quantitative tube in advance, and then opens the valve body and the hydraulic cylinder. Under the action of the hydraulic cylinder, the piston rod and the piston member are driven to move, and the allopregnanolone in the quantitative tube is squeezed out under the action of the piston member. Since the capacity of the quantitative tube is fixed, the allopregnanolone in the quantitative tube is quantitatively added under the action of the quantitative scale line, so as to achieve the purpose of quantitatively adding allopregnanolone. Compared with the existing method, the utility model can automatically add allopregnanolone quantitatively, replaces the manual adding method, reduces the labor intensity of the manual workers, and improves the precision of quantitatively adding allopregnanolone.

[0024] The utility model can remove the limit ring from the threaded part, and then take the threaded part out of the first connecting hole and the second connecting hole, so that the connecting strip and the set can be disassembled and separated, and then the fixing pin is pulled, and the compression spring will perform corresponding stretching movement. After one end of the fixing pin is disengaged from the second clamping hole, the quantitative tube can be disassembled, so the utility model is convenient for cleaning and maintenance of the quantitative tube.

Under the action of the hydraulic cylinder 3, the piston rod and the piston member 4 are driven to move, and the allopregnanolone in the quantitative tube 8 is squeezed out under the action of the piston member 4. Since the capacity of the quantitative tube 8 is fixed, the allopregnanolone in the quantitative tube 8 is quantitatively added under the action of the quantitative scale line 11, so as to achieve the purpose of quantitatively adding allopregnanolone. Compared with the existing method, the utility model can automatically add allopregnanolone quantitatively, replace the manual adding method, reduce the labor intensity of the manual labor, and improve the precision of quantitatively adding allopregnanolone.

[0038] Secondly, by removing the limit ring 21 from the threaded member 19, and then removing the threaded member 19 from the first connecting hole 17 and the second connecting hole 18, the connecting strip 6 and the set 5 can be disassembled and separated, and then the fixing pin 14 is pulled. At this time, the compression spring 16 will perform a corresponding stretching movement. After one end of the fixing pin 14 is disengaged from the second clamping hole 13, the quantitative tube 8 can be disassembled. Therefore, the utility model is convenient for cleaning and maintenance of the quantitative tube 8.
