Abstract
The utility model discloses a novel breathing circuit which comprises an exhaling pipe and an inhaling pipe. The exhaling pipe is coaxial with the inhaling pipe, the inhaling pipe is arranged inside the exhaling pipe, an air channel is reserved between the outer-diameter side of the inhaling pipe and the inner-diameter side of the exhaling pipe, and the exhaling pipe and the inhaling pipe jointly form a double-cavity breathing circuit pipe. According to the technical scheme, the novel breathing circuit has the advantages that a patient can exhale gas via the outer pipe and can inhale gas via the inner pipe, heat and moisture can be transferred between the exhaled gas and the inhaled gas via the wall of the inner pipe, accordingly, a heat-insulation effect can be realized for the gas in the inhaling pipe via the wall of the inhaling pipe while the patient exhales the gas, condensate water generated in service procedures can be reduced, the patient can inhale the gas at the temperature which keeps consistent with the body temperature of the patient, and the novel breathing circuit is convenient to operate and small in occupied space.
Description
Technical field
This utility model relates to anesthetic machine or the supporting medical breathing circuit of respirator, specifically refers to a kind of novel breathing circuit.
Background technology
Suffers from the patient of serious hypopnea, need to help to breathe with respirator, but need the patient who performs the operation, some adopts suction-type to anaesthetize, at this moment just need to cover with face shield patient's mouth and nose, be connected with respirator or anesthetic machine by respiration loop pipe, in time patient is treated.At present, existing respiration loop pipe comprises the union elbow of mutually pegging graft successively, three way cock, corrugated tubing and straight connector, wherein corrugated tubing and straight connector are two, corrugated tubing is connected to after being connected successively with straight connector on wherein two mouths of pipe of three way cock, and union elbow is connected with face shield, straight connector and respirator or anesthetic machine are connected, adopt above-mentioned respiration loop pipe, can make patient pass through face shield is connected with respirator or anesthetic machine well, but in use, because corrugated tubing and the straight connector of respiration loop pipe all have two, and be connected to two ports of three way cock, have and take up room greatly, the deficiency of inconvenient operation, and winter when cold day suction nozzle administration cooler.
Utility model content
The purpose of this utility model is to provide a kind of little and easy to operate novel breathing circuit that takes up room.
To achieve these goals, this utility model is designed a kind of novel breathing circuit, comprise exhaust tube and suction nozzle, described exhaust tube is coaxial setting with suction nozzle, suction nozzle is arranged on the inside of exhaust tube, between the external diameter of suction nozzle and the internal diameter of exhaust tube, leave air duct, exhaust tube forms double-cavity breathing circuit pipe together with suction nozzle.
For making to facilitate patient to use, described exhaust tube is ripple exhaust tube, and described suction nozzle is ripple suction nozzle.
Further, one end of described double-cavity breathing circuit pipe is connected with straight connector, and the other end is connected with three way cock.
Again further, two other interface of described three way cock, one is provided with shrouding, and another is connected with corrugated tube, and the end of corrugated tube is breathed interface with respirator and is connected.
The beneficial effect of this utility model breathing circuit: by exhaust tube and suction nozzle are coaxially arranged, and suction nozzle is arranged on to the inside of exhaust tube, between the external diameter of suction nozzle and the internal diameter of exhaust tube, leave air duct, exhaust tube forms double-cavity breathing circuit pipe together with suction nozzle, employing inner tube is air-breathing, the technical scheme of outer expiratory tube, be convenient to exhale and air-breathing by inner tubal wall carry out heat wet exchange, make patient exhale in can by suction nozzle tube wall to suction nozzle in gas be incubated, use procedure can reduce condensed water and produce, make patient can suck the gas being consistent with body temperature, have advantages of easy to operate simultaneously and take up room little.
brief description of the drawings:
Fig. 1 is the structural representation of this utility model breathing circuit.
Detailed description of the invention
For the ease of those skilled in the art's understanding, below in conjunction with specific embodiment and accompanying drawing, structural principle of the present utility model is described in further detail.
As shown in Figure 1, a kind of novel breathing circuit, comprise exhaust tube 2 and suction nozzle 3, described exhaust tube 2 is coaxial setting with suction nozzle 3, suction nozzle 3 is arranged on the inside of exhaust tube 2, between the internal diameter of the external diameter of suction nozzle 3 and exhaust tube 2, leave air duct 7, exhaust tube 2 forms double-cavity breathing circuit pipe together with suction nozzle 3, described exhaust tube 2 is ripple exhaust tube, described suction nozzle 3 is ripple suction nozzle, one end of described double-cavity breathing circuit pipe is connected with straight connector 1, the other end is connected with three way cock 4, described three way cock 4 is connected with corrugated tube 5, the end of corrugated tube 5 is breathed interface 6 with respirator and is connected.
As shown in Figure 1, this utility model breathing circuit is by coaxially arranging exhaust tube 2 and suction nozzle 3, and suction nozzle 3 is arranged on to the inside of exhaust tube 2, between the internal diameter of the external diameter of suction nozzle 3 and exhaust tube 2, leave air duct 7, exhaust tube 2 forms double-cavity breathing circuit pipe together with suction nozzle 3, adopt exhaust tube 2 to be used for exhaling as outer tube, suction nozzle 3 is used for air-breathing technical scheme as inner tube, be convenient to exhale and air-breathing by suction nozzle 3 tube walls carry out heat wet exchange, patient can be incubated the interior gas of suction nozzle 3 by suction nozzle 3 tube walls in exhaling, use procedure can reduce condensed water and produce, make patient can suck the gas being consistent with body temperature, have advantages of easy to operate simultaneously and take up room little.
Foregoing, is only preferred embodiment of the present utility model, and not for limiting embodiment of the present utility model, those skilled in the art are according to design of the present utility model, and the appropriate adaptation of having done or amendment, all should be within protection domain of the present utility model.
