Abstract

The invention provides a multi-sample negative pressure suction sampler for the endocrinology department. The multi-sample negative pressure suction sampler comprises a sampler body and a sampling box, wherein the sampling box comprises a box body and N sample storage pipes mounted on the box body; each sample storage pipe comprises a pipe body with two open ends, a liquid inlet valve head is arranged at the head end of the pipe body, and a sealing rubber plug is arranged at the tail end of the pipe body; the sampler body comprises a loading part, a liquid suction part and a negative pressure suction part; and after the sampling box is mounted, the liquid inlet valve heads of the N sample storage pipes are inserted into N liquid suction covers respectively, and air suction needles can penetrate through the sealing rubber plugs of the sample storage pipes to extend into the sample storage pipes after moving. The suction sampler adopts a loading structure, sampling operation can be performed after the independent sampling box is loaded during use, working position switching of the multiple sample storage pipes can be realized through simple rotation and push-pull 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 a multi-sample negative pressure suction sampler used in the department of endocrinology. Background technique [0002] Endocrine refers to a form of secretion in which hormones produced by secretory cells are directly secreted into body fluids, and the body fluids are used as a medium to produce effects on target cells. They include the pituitary, thyroid, parathyroid, adrenal, gonads, pancreatic islets, thymus, and pineal gland. These glands secrete high-efficiency organic chemical substances (hormones), which transmit chemical information to their target cells, target tissues or organs through blood circulation, and exert excitatory or inhibitory effects. [0003] Endocrine disorders can lead to fluid accumulation in the chest cavity, abdominal cavity, pelvic cavity and other parts. The existing main treatment method is to draw fluid through a syringe. The current suc...
