Description

A kind of Medical tracheal tube casing tube oxygen supply port

Technical field

The utility model relates to a kind of oxygen supply port, specifically a kind of Medical tracheal tube casing tube supplies oxygen port.

Background technique

Tracheotomy is releasing patient ventilation's dysfunction in medical treatment, maintains patient airway exploitation and promotes the normal of expectoration Use means.The oxygen supply of patient mostly uses the mode supplied oxygen in medical flexible conduit insertion air flue after tracheotomy at present.This kind Method is especially blown out since oxygen is blown out from single duct in insertion air flue with high-speed flow, there are various disadvantages:

1. causing air flue dry, there is the dry adherency of sputum and obstructing airway；

2. oxygen catheter is inserted into air flue for a long time, mucocutaneous membrane is impacted by high speed oxygen stream in air flue, mucocutaneous membrane in air flue occurs Dry, endothelial cell protective barrier is destroyed, bacterium intrusion, and secondary severe infections often cause critical patient is dead to originate Factor；

3. conduit insertion is too deep due to using soft fine duct plug-in type oxygen supply, sputum discharge is obstructed, and insertion is shallower again Easily deviate from cough, expectoration, oxygen supply is caused to be cut off.The workload and operating pressure of nursing observation are thereby increased, it is practical The case where abjection of patient oxygen conduit cannot be found early is usually seen in clinical position, the danger that making patients' anoxic occurs；

4. being fastened oxygen flexible conduit mode using adhesive tape in the past must be in time once sputum pollution adhesive tape, occurs in expectoration It replaces and from new fixed catheter, brings very big burden to nursing cleaning；

5. in suction sputum nursing, because the insertion of soft conduit hinders suction sputum access, often needing first to extract soft tracheal catheter, inhaling Oxygen supply is inevitably interrupted in phlegm operating process；

6. after soft conduit is deviate from or operates artificial extract because of suction sputum, conduit insertion end is easy to be returned again by outside contamination It is inserted into air flue and increases nosocomial bacteria infection chance.

In view of the foregoing, the experience and thinking in this patent combination clinical position changes soft plug-in type oxygen supply mode, Devise tracheal tube oxygen supply port.

Utility model content

Purpose of the utility model is to solve the oxygen supplies of patient after tracheotomy to blow out from single duct, brings The problem that air flue is dry, the dry adherency of sputum and obstructing airway, easy anoxic, work load are big.

The technical solution adopted in the utility model is: a kind of Medical tracheal tube casing tube supplies oxygen port, it is characterised in that: including can The hard ring sleeve on the external port of tracheal tube is covered, is fixedly connected on the top surface of the hard ring sleeve hollow Oxygen disperse pipe, the outside of the oxygen disperse pipe are equipped with oxygen catheter, can be to filling inside oxygen disperse pipe by oxygen catheter Enter oxygen, there also is provided no less than 1 oxygen disperse hole on the inside of oxygen disperse pipe.

Further, oxygen disperse hole is according to the vertical range apart from oxygen catheter input port on oxygen disperse pipe Distance setting pore size, successively increases aperture from the near to the distant, keeps the blowout air-flow velocity from each hole uniform.

It further, is 0~90 degree from the angle [alpha] of oxygen disperse hole oxygen flow gone out downwards.

Further, oxygen disperse hole is evenly arranged on the interior side ring surface of oxygen disperse pipe, and quantity is 2~8 It is a.

The beneficial effects of the utility model and feature are: (1) design is same in supply by multi-pore channel distributing oxygen supply In the case of oxygen flow, the oxygen flow milder of generation, oxygen being more evenly distributed in air flue avoids deep in air flue Mucous epithelium is directly impacted the damage of appearance by single high-speed flow；(2) design effectively avoids oxygen hose road and is easy The problems such as abjection and the past need to frequently replace adhesive tape using the fixed increase sputum pollution of adhesive tape, reduction nursery work intensity is same When, oxygen supply is safer；(3) the case where multi-pore channel oxygen supply, oxygen supply is cut off after avoiding unitary catheter from blocking；Hard port, Simple cleaning easy to assemble；(4) the hollow airway obstruction solved in the case of the insertion of previous hose of dispersion ring, suction sputum care operation without It need to remove, supply oxygen without interruption, and effectively prevent pollution and bacterium intrusion caused by soft conduit is deviate from and returned in slotting.

Specific embodiment

The utility model is further described with reference to the accompanying drawing:

As shown in Figure 1 and Figure 2, a kind of Medical tracheal tube casing tube supplies oxygen port, including can cover on the external port 5 of tracheal tube Hard ring sleeve 1, the hard ring sleeve 1 using hard annular sleeve as oxygen supply port seat, can securely be sleeved on gas On the external port of pipe conduit, fixation is not easily to fall off, while can remove cleaned at any time again after using.

Hollow oxygen disperse pipe 2, the oxygen disperse pipe 2 are fixedly connected on the top surface of the hard ring sleeve 1 Outside be equipped with oxygen catheter 4, by oxygen catheter 4 can to being filled with oxygen inside oxygen disperse pipe 2, oxygen disperse pipe 2 it is interior Side there also is provided no less than 1 oxygen disperse hole 3.

As the design of optimization, oxygen disperse hole 3 according to apart from oxygen catheter 4 on oxygen disperse pipe 2 input port Pore size is arranged in 41 vertical range distance, successively increases aperture from the near to the distant, keeps the blowout air-flow velocity from each hole uniform.

It is 0 from the angle [alpha] (being specifically shown in detailed angular marking in Fig. 5) of 3 oxygen flow of oxygen disperse hole gone out downwards ~90 degree, by 3 angle of oxygen disperse hole, can control oxygen blow-off direction, make each hole oxygen towards tracheal tube center and Lower section blowout in pipeline, air-flow is mild, is convenient for patient's oxygen intake, will not in air flue mucocutaneous membrane it is dry；

Oxygen disperse hole 3 is evenly arranged on the interior side ring surface of oxygen disperse pipe 2, and quantity is preferably 2~8, Multiple apertures also can be supplied oxygen normally even if Partial Blocking, ensure that the reliability of oxygen supply.

The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments Only illustrate the structural relation and principle of the utility model, on the premise of not departing from the spirit and scope of the utility model, this Utility model will also have various changes and improvements, and these various changes and improvements fall within the scope of the claimed invention.
