Abstract

The utility model discloses a three chambeies of canned type joint of ventilating should connect operation pipe, the air supply pipe of lower part and the coherent pipe of lateral part including upper portion, it is connected with the airtight pipe that the middle part has the sealed lamella of elasticity to manage upper portion in the operation, airtight tub of upper portion is connected with by last card pipe, lower clamping ring and presss from both sides the choke cap that the elasticity lamella form choke piece in the middle of them constitutes. When needs fiberoptic bronchoscope inspection or when inhaling operation such as phlegm, with fiberoptic bronchoscope or inhale lamella form choke piece and the sealed lamella in airtight pipe of phlegm pipe from the choke cap in and insert, elastic lamella form choke piece and sealed lamella are with fiberoptic bronchoscope or to inhale the airtight encirclement of phlegm pipe shape sealed, and it is sealed both to have made long time operated also can remain throughout, gas leakage can not appear, has guaranteed the suction of patient's oxygen or narcotic drug. Simultaneously, elastic lamella form choke piece and sealed lamella can also adapt to the device for insertion of different thickness specifications, can not be because of the diameter thickness of device for insertion the phenomenon that takes place to leak gas, convenient operation increases operating efficiency.

Description

Closed type three chamber ventilating joint
One, technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of closed type three chamber ventilating joint.
Two, background technology
In mechanical ventilation, when carrying out fiberoptic bronchoscopy or suction sputum operation, generally requiring disconnection respirator, oxygen reserve as critical in patient is low, operating time critical constraints.For solving the problems referred to above, patent No. ZL201220256331.8 discloses a kind of bronchoscopy Special connecting joint, trachea that this joint is connected with respirator or anesthetic machine by the air supply pipe intubated with patient's trachea or the aeration equipment such as laryngeal mask is connected and being made up of the operation pipe of sealing cap closure at ordinary times.When needing bronchoscopy or suction sputum, opening sealing cap and insert bronchoscope or sputum aspirator tube from operation pipe, insertion process is not owing to having sealing device, it is difficult to prevent during mechanical ventilation leak gas, when being connected with respirator, strong influence patient's oxygen sucks, life-threatening safety;When being connected with anesthetic machine, have a strong impact on again anesthetics and suck.
Three, summary of the invention
The purpose of this utility model is to provide a kind of rational in infrastructure, is skillfully constructed, when patient is carried out long-time operation, it is possible to remain sealing, does not haves gas leakage, affects patient's oxygen or the closed type three chamber ventilating joint of anesthetics suction.
For achieving the above object, this utility model employing technical scheme is: this joint includes operation pipe, the air supply pipe of bottom and the trachea of sidepiece on top;It is characterized in: connect the sealed tube having middle part with elastic packing lobe on operation pipe top;Sealed tube top connects to be had by upper card pipe, lower snap ring and is clipped in the choke cap that the elastic flap gas barrier plate of between which is constituted.
Essence of the present utility model is to be sequentially installed with sealed tube and choke cap on operation pipe top, and the sealed tube with elastic packing lobe remains sealing at ordinary times, plays the effect of original sealing cap.When needs fiberoptic bronchoscopy or suction sputum etc. operate, by branchofiberoscope or sputum aspirator tube, the flap gas barrier plate in choke cap and the sealing flap sealed tube are inserted, airtight to branchofiberoscope or sputum aspirator tube encirclement shape is sealed by elastic flap gas barrier plate and sealing flap, both long-time operation had been made also can to remain sealing, do not have gas leakage, it is ensured that the oxygen of patient or the suction of anesthetics.Meanwhile, elastic flap gas barrier plate and sealing flap may also adapt to the insertion equipment of different thicknesses specification, because of the diameter thickness of the equipment of insertion, gas leak phenomenon will not occur, easy to operate, increase operating efficiency.This utility model is rational in infrastructure, is skillfully constructed, simple for structure compact, low cost of manufacture, the simple side of use, has filled up the blank of this type of joint, has been worth popularization and application widely.This utility model has the advantage that 1, anti-gas-leak function is strong, does not affect respirator or anesthetic machine work, does not affect anesthetics and suck.2, coordinating laryngeal mask to insert branchofiberoscope by this utility model and carry out intratracheal foreign body taking-up, now anesthesia can give muscle relaxant and carry out mechanical ventilation and perform the operation, and anaesthetizes to tracheal foreign body removal and provides new ventilating mode.3, the surgery anesthesias such as child's alveolar washing it are applicable to.4, long-term inpatients ICU patient can not turn off respirator and carries out the operation such as suction sputum, and clinical meaning is huge.
Four, accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is exploded view of the present utility model;
Fig. 3 is the internal structure schematic diagram of this utility model choke tube.
Five, detailed description of the invention
As it can be seen, the trachea 2 that is connected with respirator or anesthetic machine of the air supply pipe 1 that this utility model includes intubating with patient's trachea or the aeration equipment such as laryngeal mask is connected and operation pipe 3.It is connected with the middle part sealed tube 4 with elastic packing lobe 9 on operation pipe 3 top.Sealed tube 4 top connects to be had by upper card pipe 5-3, lower snap ring 5-1 and is clipped in the choke cap 5 that the elastic flap gas barrier plate 5-2 of between which is constituted.Lower snap ring 5-1 is inserted in the interior intracavity on choke tube 4 top.Upper card pipe 5-3 and lower snap ring 5-1 is cooperated by card column 7 and hole clipping 8 flap gas barrier plate 5-2 is stuck between which.Described elastic packing lobe 9 is mutually extruded airtight elastic force lobe and constitutes by two panels joint, remains sealing at ordinary times.Described elastic flap gas barrier plate 5-2 is multiple structure, and every layer is made up of multiple elastic force lobes, and the top of each elastic force lobe is gathered to center, and has the guide hole 6 of 2.8-4.0mm in center, and this guide hole 6 plays guide effect, it is simple to the equipment that inserts inserts.Described elastic packing lobe 9 and property flap gas barrier plate 5-2 are made by quality of rubber materials.
