Abstract
The utility model discloses a multifunctional tee used on a respirator. The multifunctional tee used on the respirator comprises a main tube, a first connecting end used for being connected with a trachea cannula is arranged at one end of the main tube, a second connecting end is arranged at the other end of the main tube, and a third connecting end used for being connected with the respirator is further arranged on the outer side wall of the main tube; an elastic sealing part is arranged at the second connecting end, the sealing part is composed of a sealing body and a sealing cover which are connected through a connecting band, a stepped through hole penetrating through the two end faces is formed in the center of the sealing body in the axial direction, the large-diameter hole end of the sealing body is connected to the second connecting end in a fastened mode, and the small-diameter hole end of the sealing body is covered with the sealing cover. The multifunctional tee used on the respirator can prevent gas leakage in the operating process of an operation, and the safety performance of the operation is greatly improved.
Description
Technical field
This utility model belongs to medical auxiliary apparatus, is specifically related to a kind of for the Multifunctional three-way valve on respirator.
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, when 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 purpose of this utility model is to provide a kind of for the Multifunctional three-way valve on respirator.
In order to realize foregoing invention object, this utility model adopts technical scheme as described below:
A kind of for the Multifunctional three-way valve on respirator, comprise supervisor, supervisor's a end is provided with for connecting the first link of 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 comprised 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 utlity model has following superiority:
This utility model is simple in structure, reasonable in design, this threeway connects respectively respirator and tracheal intubation, when needs suction sputum, on the one hand need not be again by respirator interruption separated with tracheal intubation, 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 guaranteed when suction sputum, can not leak gas, improve operation safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
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.
The specific embodiment
Below in conjunction with drawings and Examples, this utility model is described in further detail.
As shown in Figure 1, a kind of for the Multifunctional three-way valve on respirator, comprise supervisor 1, an end of supervisor 1 is provided with for connecting the first link 5 of 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 comprised 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 to small diameter bore section, pass through from major diameter nose end.
Seal 3.1 in this utility model, seal cover 3.2 all adopt elastomeric material to make, as silica gel.
This utility model is when concrete application, the first link is connected with respirator, the 3rd link is connected with tracheal intubation, the second link can be used 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; By using threeway of the present utility model, in suction sputum or do tracheascope when operation, all do not need to interrupt the work of respirator, greatly improved operation safety; In addition, the diameter of the small diameter bore in the seal in this utility model is made as 1.5-2mm, conventionally sputum aspirator tube diameter is that the diameter of 2-5.5mm, 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, prevented the gas leakage in operative process, operation safety is improved greatly.
In addition, by the 4th link, can in tracheal intubation, splash into humidifying medicine, for humidifying airway.
