摘要:
The invention relates to an assisted-respiration apparatus for small laboratory animals, such as rats, guinea-pigs and the like. According to the invention, the apparatus comprises an inspiratory circuit and an expiratory circuit which are connected by some tubes (4) to an endotracheal intubation catheter, where the inspiratory circuit, having the role of pumping gas into the lungs of an animal, consists of a gas reservoir, a compressor (1) intended to increase gas pressure and pump it into the circuit, a valve (2) for the control of the gas flow and a pressure gauge (3) which monitors the gas pressure level, while the expiratory circuit, having the role of taking over the gas resulting from expiration, consists of a PEEP device intended to prevent the pressure within the air ways to fall down to zero level at the end of an expiration, an expiratory valve (VE) having a rubber piston (7) for periodically obturating a cylinder (6), the paced movement of the piston (7) being started by a coil (10) controlled by an electronic circuit (11) which also controls the respiration frequency change by changing the charge frequency of the coil (10).Invenţia se referă la un aparat de respiraţie artificială, pentru animale mici de laborator, cum ar fi şobolani, cobai şi altele asemenea. Aparatul conform invenţiei este alcătuit dintr-un circuit inspirator şi un circuit expirator, conectate, prin intermediul unor tuburi (4), la un cateter de intubaţie endotraheală, circuitul inspirator, ce are rolul de a pompa gaz în plămânii unui animal, fiind format dintr-un rezervor cu gaz, un compresor (1) pentru ridicarea presiunii gazului şi pomparea acestuia în circuit, un robinet (2) pentru reglarea fluxului de gaz, şi un manometru (3) pentru monitorizarea nivelului presiunii gazului, iar circuitul expirator, ce are rolul de a prelua gazele rezultate în urma expiraţiei, fiind alcătuit dintr-un dispozitiv PEEP, destinat a împiedica scăderea la zero a presiunii în căile respiratorii la sfârşit
