Abstract
The invention discloses a multifunctional tee joint which comprises a main pipe. One end of the main pipe is provided with a first connecting end for being connected with a trachea cannula. The other end of the main pipe is provided with a second connecting end. A third connecting end for being connected with a breathing machine is arranged on the outer side wall of the main pipe. The second connecting end is provided with an elastic sealing piece which comprises a sealing body and a sealing cover. The sealing body and the sealing cover are connected through a connecting belt. A step through hole which is communicated with the two end faces is formed in the center of the sealing body in the axis direction. A large-diameter hole end of the sealing body is in fastening connection with the second connecting end. The sealing cover is arranged at a small-diameter hole end of the sealing body in a covering mode. According to the multifunctional tee joint, air leakage during an operation can be avoided, and accordingly operation safety is greatly improved.
Description
technical field
The invention belongs to medical auxiliary apparatus, be specifically related to a kind of Multifunctional three-way valve.
Background technology
In clinical, while doing thoracic cavity, abdominal operation, conventionally need to use tracheal intubation, one end of tracheal intubation is deep in patient body, and the other end is connected with respirator, but often tracheal intubation be not very fastening being connected of respirator, in operation process, easily gas leakage, has increased operation risk; In addition, in the time of suction sputum, often need respirator is stopped and separating with tracheal intubation, this has increased a lot of troubles to medical worker, and affects very much operation process.
Summary of the invention
In order to solve problems of the prior art, the object of this invention is to provide a kind of Multifunctional three-way valve.
In order to realize foregoing invention object, the present invention adopts technical scheme as described below:
A kind of Multifunctional three-way valve, comprise supervisor, supervisor's a end is provided with the first link for connecting tracheal intubation, the other end is provided with the second link, on supervisor's lateral wall, be also provided with the 3rd link for being connected with respirator, the second described link is provided with elastic sealing element, sealing member is made up of the seal being connected by connecting band and seal cover, the center of seal offers the ladder hole that runs through both ends of the surface along axis direction, major diameter nose end and the second link on seal are fastenedly connected, described seal cover lid is located on the minor diameter nose end on seal.
Further, the inwall of the major diameter nose end on described seal is provided with screw thread, and seal and the second link spin by screw thread.
Further, the larger diameter end on described seal is set on the outer wall of the second link.
Further, on described supervisor's lateral wall, be also provided with the 4th link that can open and close, and the 4th link is symmetrical with the 3rd link on supervisor's sidewall.
Owing to adopting technique scheme, the present invention has following superiority:
The present invention is simple in structure, reasonable in design, this threeway connects respectively respirator and tracheal intubation, in the time of needs suction sputum, need not again respirator be interrupted and be separated with tracheal intubation on the one hand, on the other hand by the centre bore through seal on the second link by sputum aspirator tube, stretch into and in tracheal intubation, carry out suction sputum operation, and the diameter of small diameter bore on seal is related to the diameter that is less than sputum aspirator tube, sputum aspirator tube is only stuck in the small diameter bore of seal, so just ensure in the time of suction sputum, can not leak gas, improve operation safety.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
In figure: 1-supervisor; 2-the second link; 3-sealing member; 3.1-seal; 3.2-seal cover; 4-the 3rd link; 5-the first link; 6-the 4th link.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further detailed explanation.
As shown in Figure 1, a kind of Multifunctional three-way valve, comprise supervisor 1, an end of supervisor 1 is provided with the first link 5 for connecting tracheal intubation, the other end is provided with the second link 2, on supervisor 1 lateral wall, be also provided with the 3rd link 4 for being connected with respirator, the second described link is provided with elastic sealing element 3, sealing member 3 is made up of the seal 3.1 being connected by connecting band and seal cover 3.2, the center of seal 3.1 offers the ladder hole that runs through both ends of the surface along axis direction, major diameter nose end on seal 3.1 and the second link 2 are fastenedly connected, described seal cover 3.2 lids are located on the minor diameter nose end on seal, for the minor diameter stomidium on seal is sealed.
The connected mode of seal 3.1 and the second link 2 can adopt: 1) inwall of the major diameter nose end on described seal is provided with screw thread, and seal and the second link are threaded connection; 2) larger diameter end on described seal 3.1 is set on the outer wall of the second link.
On described supervisor's 1 lateral wall, be also provided with the 4th link 6 that can open and close, and the 4th link is symmetrical with the 3rd link 4 on supervisor's sidewall.
In ladder hole in described seal 3.1, be provided with unidirectional valve, unidirectional valve is arranged in large diameter hole or in small diameter bore, unidirectional valve passes through to major diameter nose end from minor diameter nose end for gas, and can not pass through to small diameter bore section from major diameter nose end.
Seal 3.1 in the present invention, seal cover 3.2 all adopt elastomeric material to make, as silica gel.
The present invention is in the time of concrete application, the first link is connected with respirator, the 3rd link is connected with tracheal intubation, the second link can use according to actual operation operation, during as needs suction sputum, sputum aspirator tube extend in tracheal intubation through supervisor through the ladder hole on seal, and carries out suction sputum operation; Or while doing tracheascope operation interventional therapy, aforesaid sputum aspirator tube is replaced to tracheascope, applicable equally; The threeway of the application of the invention, in suction sputum or do tracheascope when operation, all does not need to interrupt the work of respirator, has greatly improved operation safety; In addition, the diameter of the small diameter bore in the seal in the present invention is made as 1.5-2mm, conventionally the diameter of sputum aspirator tube or tracheascope is 6mm left and right, and seal employing is that the material that the elasticity such as silica gel are larger is made, so just make the sidewall of the small diameter bore of seal only contact with the sidewall of sputum aspirator tube or tracheascope, prevent the gas leakage in operative process, operation safety is improved greatly.
