Abstract
The utility model relates to a disposable sealed type sputum sucking device which comprises a patient end interface unit, a sputum sucking pipe assembly and a sucking switch, wherein one end of the sucking switch is connected with the sputum sucking pipe assembly; the patient end interface unit has a four-way interface structure, and the sputum sucking pipe assembly is a fully sealed structure, the inner part of which is connected with a sputum sucking pipe and the outer part is covered with a film sleeve; the thickness of the film sleeve is between 0.03 micron and 0.05 micron; and both ends of the film sleeve are respectively fastened with a film front nozzle and a film rear nozzle by a seal sleeve and a clamping hoop which are made of silica gel materials. The utility model has simple, convenient and rapid operation and lightens the working strength of medical workers without special device. The seal sleeve and a seal gasket in a slide valve switch are made of the silica gel materials and can prevent the sputum sucking device from generating various liquid leakage conditions and causing direct infection on the medical workers when a retraction phenomenon is generated; and the structure can prevent the phenomenon that sputum flows over other parts because the sucking switch can not be reset normally, and the sucking switch has safety and reliability in clinical operation.
Description
Technical field
This utility model belongs to the clinical medicine utensil, particularly relates to a kind of disposable closed endotracheal suction device.
Background technology
At present in respiratory system disease, general anesthesia operation treatment and the emergency rescue, often need carry out tracheal intubation or tracheotomy, and employing and the matching used closed sputum aspirator tube of artificial respirator are supported its treatment to the patient.Known closed sputum aspirator tube mainly is to connect the patient end of slide valve switch, the sputum aspirator tube assembly that is communicated with the three way cock and the suction shaft that is communicated with the sputum aspirator tube assembly constitutes by the three way cock.Because above-mentioned closed endotracheal suction device do not possess injection liquid mouth, therefore rescue or treatment in need at any time the patient to be used spasmolytic and medicine such as reduce phlegm, can only solve by special device, its complex operation and inconvenience are the shortcomings of giving prominence to.In addition, the thin film of sputum aspirator tube assembly cover two ends by the styrene block copolymer material sealing shroud and clip respectively with thin film before tight-lipped solid behind mouth and the thin film, because thin film cover thickness is thicker, not only can cause inadequately, and also be not easy to medical personnel operation clinically with the bonding strength of clip; When rebound phenomenon appears in the sealing gasket in sealing shroud and the slide valve switch, make sputum aspirator tube produce various leakage situations easily, very easily medical personnel are caused direct infection.
Summary of the invention
This utility model provides a kind of reasonable in design, strengthens security reliability and is convenient to the disposable closed endotracheal suction device that medical personnel operate for solving the technical problem that exists in the known technology.
The technical scheme that this utility model is taked for the technical problem that exists in the solution known technology is: disposable closed endotracheal suction device, comprise the patient end interface unit, the suction shaft that a sputum aspirator tube assembly that is connected with the patient end interface unit and an end are connected with the sputum aspirator tube assembly, it is characterized in that: described patient end interface unit adopts the four-way interface structure, described sputum aspirator tube assembly is to connect sputum aspirator tube in it, it is covered with the full-closed structure of thin film cover, and by mouth connection patient end interface unit before the thin film, the thickness of described thin film cover is 0.03-0.05um, sealing shroud that thin film cover two ends make by silica gel material and clip respectively with thin film before tight-lipped solid behind mouth and the thin film.
This utility model can also adopt following technical scheme:
Described patient end four-way interface unit comprises an interface body, an end is connected with the rotatable interface core in this interface body, and the other end is communicated with valve block, and slide valve switch is housed on the valve block, described interface body top also is provided with the injection liquid mouth with its perforation, and the bottom is communicated with swivel joint.
The sealing gasket that silica gel material is made is housed in the described slide valve switch.
Described sealing shroud is the sealing shroud of silica gel material.
Advantage and the good effect that the utlity model has are: because this utility model adopts technique scheme, have injection liquid mouth on traditional three-way interface top, when needs were given patient's perfusion solution, inculcating pipe by injection liquid mouth connection medicinal liquid can pour into medicinal liquid in patient's body from injection liquid mouth like this.Need not to adopt special device, simple and efficient to handle, alleviated medical personnel's working strength.Sealing gasket in described sealing shroud and the slide valve switch adopts silica gel material to make, and in the time of can preventing rebound phenomenon, avoids sputum aspirator to produce various leakage situations and medical personnel are caused direct infection; The phenomenon that the sputum that adopts said structure can avoid suction shaft normally to reset and cause overflows from other position makes suction shaft have more security reliability in clinical manipulation.
