Inspiration port has pressure transfer channel communicated to pressure regulation cavity. There is a valve between expiration cavity and inspiration port. It is used for baby anesthesia, emergency treatment and respiratory monitor.
Description
A kind of children breathing valve belongs to medical instruments field, is mainly used in pediatric anesthesia, also can be used for children's's breathing support, treatment, also can be used for the emergency treatment of being grown up.
Along with medical level is particularly anaesthetized and the progress of first aid level, higher requirement is proposed for children's's breathing support and treatment.Existing various respirator, anesthetic machine are used for infant's respiration when management often because of the dead space amount is big, gas repeats to suck and causes effective ventilation deficiency, weary oxygen and carbon dioxide to accumulate, sometimes will increase respiratory frequency, increase tidal volume for fear of this situation, this can cause pleural pressure too high again, influence venous return, above situation seriously jeopardizes children's's life security, restriction pediatric anesthesia, operation, breathing support and treatment, and people in all sorts of ways and attempt to be improved solution for this reason.The improved device (Jackson-Less loop, Bain loop, Magill loop) that Ruben flap valve, T type pipe (Ayre ' s Tpiece) and T type pipe are arranged commonly used at present, but the whole bag of tricks all can not tackle the problem at its root.The Ruben flap valve, though respiration dead space is less, to need relatively large gas to cause the infant's respiration capacity excessive owing to promoting the flap valve operation, its DeGrain is not so be suitable for children's; T type pipe and improved device thereof, the existing relatively anesthetic machine of respiration dead space is less, pediatric anesthesia is many both at home and abroad at present installs with this, but its running is carried out under manually-operated fully, accident tired owing to operator or that error causes easily takes place, also exist simultaneously because difficulty is deepened in the anesthesia that open anesthesia causes, the anaesthetic consumption is big, easily causes the disadvantage of tunica mucosa tracheae drying and heat forfeiture.
Purpose of the present invention mainly is for children's particularly the problems referred to above of existing in the management of the following pediatric anesthesia of 10kg and respiratory therapy of body weight and a kind of children breathing valve of providing are provided.
Technical scheme of the present invention is as follows: the children breathing valve body has three outlets promptly: air entry, exhalation vents, patient's endotracheal tube interface; Be separated wall, sheet alive and valve in its body and be divided into three cavitys: top is that pressure regulating cavity, lower central are that gas exchange chamber, periphery are the expiration chamber; Partition wall is tubular, and the upper end level disconnects, and the sheet of living is covered on the partition wall broken ends of fractured bone, closely is fixed in body all around; Pressure regulating cavity belongs to closed dead space, gas exchange chamber and the expiration chamber is potential communicates, air entry communicates with the gas exchange chamber by valve, lower end, gas exchange chamber communicates with patient's endotracheal tube interface, air entry has a pressure conduction pathway to communicate with pressure regulating cavity before valve, and the expiration chamber communicates with exhalation vents by another valve.
The present invention both had been applicable to patient's control breathing, also be applicable to patient's assisted respiartion, both be applicable to adult patients, be more suitable for children's even infant, neonate, the present invention can make patient's breathing management accurate, quantitative, thereby avoid the generation of carbon dioxide accumulation, also avoid owing to children's's hyperventilation pleural pressure increases the venous return obstacle that causes, guarantee children's's safety, reduced medical workers simultaneously, the present invention mainly is applicable to the breathing management of pediatric anesthesia, also is applicable to the breathing Supporting Therapy of children's's first aid, monitoring.

Do further narration in conjunction with the accompanying drawings:
This body and function of children breathing valve metal or plastics are made, body 7 has three outlets promptly: air entry 3, exhalation vents 10, patient's endotracheal tube interface 9, (referring to Fig. 1) body 7 is separated wall 2, rubber sheet 5 alive and valve 4 and is divided into three chambeies, top is that pressure regulating cavity 11, lower central are gas exchange chamber 8, periphery is expiration chamber 6, and partition wall 2 is cylindric, and the upper end level disconnects, rubber sheet 5 normal recurrence of disease at the same time next year alive are placed on partition wall 2 broken ends of fractured bone, closely are fixed in body 7 all around.In three chambeies, pressure regulating cavity 11 does not communicate with gas exchange chamber 8 and expiration chamber 6 owing to the obstruction of rubber sheet 5 alive, belong to closed dead space, gas exchange chamber 8 and expiration chamber 6 are potential communicating, promptly under normal circumstances rubber is lived, and to be close to two chambeies, partition wall 2 upper ends then obstructed for sheet 5, when downforce changes on rubber is lived sheet 5, if living, moves on the sheet 5 by rubber, two chambeies then communicate, air entry 3 communicates with gas exchange chamber 8 by valve 4, and 8 lower ends, gas exchange chamber lead to patient's endotracheal tube interface 9, and air entry 3 has a pressure conduction pathway 1 logical pressure regulating cavity 11 before valve 4, do not participate in the air communication mistake, expiration chamber 6 is by another valve 4 logical exhalation vents 10 (referring to Fig. 1).Its working mechanism mainly is the various combination by three outlets, three chambeies and two valve, a sheet alive and a pressure transmission pipe, make in the respiratory air-flow follow air entry → patient respiratory road → exhalation vents fully and carry out, the dead space amount in the infant's respiration management of fundamentally having solved is excessive, gas repeats to suck the carbon dioxide accumulation that causes, the ventilation capacity is excessive, pleural pressure increases and the difficult problem of venous return obstacle.This children breathing valve promptly is applicable to patient's control breathing, also is applicable to patient's assisted respiartion.
Operation principle of the present invention is as follows:
Control breathing-inspiratory phase: the gas of certain pressure enters gas exchange chamber 8 by valve 4, sheet 5 produces the P that upwards pressure to living, because the gas of air entry 3 can be delivered to pressure regulating cavity 11 with pressure P by pressure conduction pathway 1, sheet 5 produces downward pressure P to living, sheet 5 actual loadings are zero and do not produce displacement so live, the gas that enters gas exchange chamber 8 like this can only enter patient's endotracheal tube interface 9, finally enters the patient respiratory road, finishes control breathing-inspiratory phase (referring to Fig. 2).
Control breathing-expiratory phase: the gas of certain pressure enters gas exchange chamber 8 by patient's endotracheal tube interface 9, because the unidirectional obstruction of valve 4, gas can not be back to air entry 3, this moment, pressure regulating cavity 11 and expiration chamber 6 pressure all were zero, so the gas in gas exchange chamber 8 is pushed open sheet 5 alive, enter expiration chamber 6, discharge exhalation vents 10, finish control breathing gas phase (referring to Fig. 3) by valve 4.
Assisted respiartion-inspiratory phase: produce negative pressure during patient respiratory, be delivered to gas exchange chamber 8 by patient's endotracheal tube interface 9, produce identical negative pressure, because the pressure of pressure regulating cavity 11 is zero at this moment, so the time live that sheet 5 is actual to be subjected to a downward pressure, and be blocked in the upper end in gas exchange chamber 8; Because the pressure of air entry 3 also is zero, the pressure in gas exchange chamber 8 is malleation relatively, and gas can be pushed valve 4 open and enter gas exchange chamber 8, and enters the patient respiratory road by patient's endotracheal tube interface 9, finishes assisted respiartion-expiratory phase (referring to Fig. 4).
Assisted respiartion-expiratory phase: same control breathing-expiratory phase.
