The large mice breathing mask that we carry out and large mice breathing mask Universal fixer serial experiment research work, its object is exactly to solve rat in art and postoperatively ductus nasopharyngeus can be kept to have air-flow to pass through and not blocked, the problem of the dyspnea that effective prevention of postoperative occurs or the serious respiratory tract obstruction such as to suffocate, considerably improve success rate, stability and work efficiency prepared by large mice myocardial infarction and ischemia model, sized by Mus chronic myocardial ischemia research built reliable zoopery platform.Because this research work has no report both at home and abroad, we when without any data can reference, the completely independent design and fabrication work carrying out large mice face shield Universal fixer.
In design and fabrication, emphasis solves following three critical problems:
(1) breathing mask Universal fixer base designs
The jawbone holder that 1, will be applicable to varying in size fixing.In order to address this problem, we devise rat mandible holder entrance and mice jawbone holder entrance respectively before face shield holder base, being provided with locker in the both sides of base, after jawbone holder inserts from entrance, good fixed effect can being played by regulating locker.
2, face shield Universal fixer base and operating-table is fixing.In order to convenient to operation, we are at back end design fixing hole and the locker of face shield holder base, and operating-table is provided with fixed bar, inserted by fixed bar, play the fixation of base and operating-table by locker after being locked from the fixing hole base.
3, the connection of base and top breathing mask standing part.Can move forward and backward on base to make face shield standing part, we are provided with the mobile chute of strip in the centre of submounts, be connected with the sliding tray unlock button on face shield holder with pull bar, play face shield standing part on base movement and fixation.
(2) breathing mask Universal fixer functional design
1, the fixing of large mice breathing mask will be applicable to.The different diameters of large mice respiratory surface is very large, in order to realize the general fixing of large mice breathing mask, we are in the front end of face shield holder, devise applicable large mice breathing mask fixed bar patchhole respectively, side is provided with locker, after face shield fixed bar inserts from entrance, played the fixation of face shield by the locker of side.
2, breathing mask and large mouse head is fixing.After breathing mask is fixing, the fixing of face shield and head can be realized by sliding tray unlock button, press sliding tray unlock button, can driven forward face shield holder, breathing mask also moves forward thereupon, when after face shield and head close contact, unclamping sliding tray unlock button can play fixation.
(3) design that constant breathing mask and head are fixing.
The hard contact that fixedly belongs to of the breathing mask of setting forth above and head is fixed, this fixing means is along with the change of large mice head position, the seal of breathing mask and head contact can be affected, can not ensure that animal is opening the positive pressure respiration in breast situation, even can cause the death of animal.For this problem, we are through repeatedly zoopery, finally between breathing mask connecting rod and face shield holder, increase elastic pressure buffer unit, this device can when animal head position changes, still can ensure respiration the seal of face shield and head contact, maintains the positive pressure respiration function of animal in open chest surgery situation.
