Embodiment Construction

[0011] A rat gastric antrum pressure sensor probe of the present invention comprises an elastic balloon 1, an upper catheter 21, a lower catheter 22, a three-way head 3, a syringe 4 and a pressure transducer 5; the two ends of the upper catheter 21 are respectively connected to the elastic balloon 1 And the upper end of the three-way head 3, the two ends of the downcomer 22 are respectively connected to the lower end of the three-way head 3 and the pressure transducer 5, and the horizontal port of the three-way head 3 is connected to the syringe 4.

[0012] The elastic balloon 1 is the seminal storage vesicle in the front part of the condom.

[0013] The working process of a rat gastric antrum pressure sensor probe of the present invention is as follows:

[0014] (1) Before starting the experiment, drain the air in the complete set of equipment, inject physiological saline from the syringe 4, and fill the elastic balloon 1, the upper catheter 21, the lower catheter 22 and the ...

Abstract

The invention discloses a rat stomach antrum pressure sensor probe which comprises an elastic saccule, an upper catheter, a lower catheter, a tee joint, an injector and a pressure transducer. The two ends of the upper catheter are connected with the elastic saccule and the upper end of the tee joint respectively. The two ends of the lower catheter are connected the lower end of the tee joint and the pressure transducer. A horizontal through opening of the tee joint is connected with the injector. The elastic saccule is a condom front section air bag. A probe structure is greatly simplified, and the back end platform requirement is lowered. The structure is simplified, storing is easy, manufacturing can be carried out through a condom and the injector by a user, and related experiment cost is saved.

Description

technical field [0001] The invention relates to an experimental rat stomach physiological data collection device, in particular to a rat gastric antrum pressure sensor probe. Background technique [0002] The orderly and powerful contraction of gastric antrum muscles is an important physiological link in the emptying of gastric contents. Translating their motor function into data that can be collected and analyzed is a necessary step in medical research. Gastric electrogastrometry and gastric pressure analysis are the most commonly used protocols for gastric motility analysis. [0003] Electrogastrogram is the most commonly used clinical detection scheme, and its non-invasive and painless features make it widely welcomed by patients. However, in animals, the frequency of gastric electrophysiology and diaphragm motor potential are similar, and their positions are similar, so it is difficult to separate them by filtering, and there is no recognized animal gastric electroph...
