Description
Technical Field
The utility model particularly relates to an attraction joint, which relates to the field related to medical instruments.
Background
The negative pressure suction device (sputum aspirator) is used for patients who have difficulty in autonomous sputum excretion due to operations, coma, critical diseases and the like, and is a common device in intensive care units and sickrooms.
At present, some suction connectors of the same type on the market have the problems of insufficient suction force, overlarge size and the like.
SUMMERY OF THE UTILITY MODEL
Therefore, in order to solve the above-mentioned insufficiency, the present invention provides an attraction joint.
The utility model discloses a realize like this, construct an attraction and connect, the device is including attracting valve cap, attraction valve shaft, attraction valve axle sleeve and attraction valve sealing head, install the attraction valve shaft in the attraction valve cap, attraction valve cap bottom is connected with the attraction valve axle sleeve, attraction valve axle sleeve bottom is installed and is attracted valve sealing head, attraction valve shaft bottom is passed the attraction valve axle sleeve and is attracted valve sealing head sealing connection.
Preferably, the suction valve cap and the suction valve sealing head are made of soft rubber.
Preferably, the suction valve shaft and the suction valve shaft sleeve are made of plastic.
Preferably, an air inlet hole is arranged on the suction valve cap.
Preferably, a cavity is arranged inside the suction valve shaft sleeve, and an air outlet is connected to one side of the cavity.
Preferably, the cavity is communicated with an air inlet hole.
Preferably, an open circuit is arranged inside the suction valve sealing head and is communicated with the cavity channel.
The utility model has the advantages of as follows: the utility model discloses an improve and provide an attraction joint here, compare with equipment of the same type, have following improvement:
the advantages are that: an attract to connect, it need not the exclusive operation to be out of work, only need press during the use can normally work, and the during operation relies on to press and seals, has guaranteed the leakproofness of attracting the interface again, attracts the interface to reduce the size as far as under the prerequisite of guaranteeing normal performance in addition, makes things convenient for medical personnel's operation.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Wherein: the suction valve comprises a suction valve cap-1, a suction valve shaft-2, a suction valve shaft sleeve-3, a suction valve sealing head-4, an air inlet hole-5, a cavity channel-6 and an air outlet hole-7.
Detailed Description
The present invention will be described in detail with reference to the accompanying fig. 1, and the technical solutions in the embodiments of the present invention will be clearly and completely described, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model discloses an improve and provide an attraction and connect here, including attracting valve cap 1, attracting valve shaft 2, attracting valve axle sleeve 3 and attracting valve sealing head 4, install attracting valve shaft 2 in the attracting valve cap 1, attract 1 bottom of valve cap to be connected with attracting valve axle sleeve 3, attract 3 bottoms of valve axle sleeve to install attracting valve sealing head 4, attract 2 bottoms of valve shaft to pass attracting valve axle sleeve 3 and attract 4 sealing head sealing connection of valve.
Further, the suction valve cap 1 and the suction valve sealing head 4 are made of soft rubber.
Further, the suction valve shaft 2 and the suction valve shaft sleeve 3 are made of plastic.
Furthermore, an air inlet hole 5 is formed in the suction valve cap 1, a cavity 6 is formed in the suction valve shaft sleeve 3, an air outlet hole 7 is connected to one side of the cavity 6, the cavity 6 is communicated with the air inlet hole 5, and air can enter from the air inlet hole 5, pass through the cavity 6 and finally be discharged from the air outlet hole 7.
Furthermore, an open circuit is arranged inside the suction valve sealing head 4 and is communicated with the cavity channel 6, and the attracted objects can enter from the open circuit inside the suction valve sealing head 4, then pass through the cavity channel 6 and finally be discharged from the air outlet 7.
The utility model provides an attraction joint through improvement, and the working principle is as follows;
firstly, when the suction valve is not used for suction, air flow enters from an air inlet 5 when the suction valve shaft 2 and the suction valve sealing head 4 are in a sealing state, passes through a cavity channel 6 and is finally discharged from an air outlet 7;
secondly, when the suction operation is performed, the suction valve shaft 2 is pressed down to form a seal with the suction valve cap 1, so that the air inlet hole 5 is sealed, the suction valve sealing head 4 protrudes relative to the suction valve shaft 2 to form an open circuit, and the sucked object enters from the open circuit inside the suction valve sealing head 4, passes through the cavity channel 6 and is finally discharged from the air outlet hole 7.
The utility model discloses an improve and provide an attraction joint, it need not the exclusive operation to be out of work, only need press during the use can normally work, and the during operation relies on to press and seals, has guaranteed the leakproofness of attracting the interface again, and this attraction interface reduces the size as far as under the prerequisite of guaranteeing normal performance in addition, makes things convenient for medical personnel's operation.
