Abstract
The utility model relates to a medical instrument, in particular to a rotating and gradual sealing type tracheal tube. The tracheal tube consists of a connecting rib, a plug, a protection guard, a hard intubation and a silicone tube, wherein the protection guard takes the funnel shape which is formed by combining a reverse round table and a cylinder; the plug is a rubber cone with a downward tip; the hard intubation takes the cylinder shape, is positioned in the cylinder of the protection guard and is matched with the protection guard by screw thread; the lower end of the hard intubation is positioned in the silicone tube; before the silicone tube is pulled out of a trachea, the operation of gradual trachea sealing is realized only by rotating the protection guard so that the protection guard and the plug move downwards. Compared with the prior art, the operation is easier, more convenient and safer.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly relates to a kind of rotation and gradually seals the formula endotracheal tube.
Background technology
For dyspneic urgent patient, need and insert conduit with its tracheotomy usually and help patient respiration clinically.Conduit can be attempted progressively tube sealing before being pulled out trachea, treat that patient is emotionally stable fully can extract after adapting to.For many years, adopt some simple and crude ways clinically, as carrying out shutoff with cotton balls, gauze, adhesive plaster etc., make moist but these plugs are very easy, influence the plugging effect, simultaneously, cotton fiber sucks trachea can cause the uncomfortable or infection of patient, in addition, these tampers can't be fixed effectively, and it is very inconvenient to operate.
The utility model content
This utility model provides a kind of rotation simple in structure, easy to use, that can conveniently regulate air inlet port size gradually to seal the formula endotracheal tube for solving the deficiencies in the prior art.
The scheme that solves this utility model technical problem is: rotation is gradually sealed the formula endotracheal tube and is made of dowel, plug, guard shield, hard intubate and silica gel tube.Wherein guard shield is the infundibulate of rounding platform and cylinder be combined into, and there are four dowels of across distribution in the plane at the place suitable for reading of guard shield, and dowel holds together plug and guard shield.Plug is most advanced and sophisticated plantation rubber cone down.The hard intubate is a cylindrical shape, and the hard intubate is in the cylindrical portions may of guard shield, and with guard shield with threaded engagement.The lower end of hard intubate is in the silica gel tube, and hard intubate and silica gel tube are the stationary fit relation.The area of plane in the space of the formed annular in top of the top of plug and guard shield is greater than the cross-sectional area of hard intubate inner space.The diameter of the upper surface of plug is greater than the interior diameter of hard intubate.The progressively pipe sealing operation that silica gel tube need carry out before being pulled out trachea only need be passed through rotating shroud, makes guard shield move downward and can realize together with plug.
Adopt such scheme, can reach following effect:
1. the progressively pipe sealing operation that need carry out before being pulled out trachea of silica gel tube only need be passed through rotating shroud, makes guard shield move downward and can realize together with plug.Make operation more simple and easy to do like this.
2. because the shutoff speed of plug can manually be grasped by the doctor, can adapt to clinical various situations more neatly.
3. because the plug dowel is fixed, and this compares with existing shutoff means, stopped the possibility that tamper is inhaled into trachea, made operation safe.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1. dowel 2. plugs 3. guard shields 4. hard intubate 5. silica gel tubes
The specific embodiment
The utility model will be further described below in conjunction with drawings and Examples.
Rotation is gradually sealed the formula endotracheal tube and is made of dowel 1, plug 2, guard shield 3, hard intubate 4 and silica gel tube 5.Wherein guard shield 3 is the infundibulate of rounding platform and cylinder be combined into, and there are four dowels 1 of across distribution in the plane at the place suitable for reading of guard shield 3, and dowel 1 holds together plug 2 and guard shield 3.Plug 2 is most advanced and sophisticated plantation rubber cones down.Hard intubate 4 is a cylindrical shape, and hard intubate 4 is in the cylindrical portions may of guard shield 3, and with guard shield 3 with threaded engagement.The lower end of hard intubate 4 is in the silica gel tube 5, and hard intubate 4 is the stationary fit relation with silica gel tube 5.The area of plane in the space of the formed annular in top of the top of plug 2 and guard shield 3 is greater than the cross-sectional area of hard intubate 4 inner spaces.The diameter of the upper surface of plug 2 is greater than the interior diameter of hard intubate 4.The progressively pipe sealing operation that silica gel tube 5 need carry out before being pulled out trachea only need be passed through rotating shroud 3, makes guard shield 3 move downward and can realize together with plug 2.
Claims (1)
1. a rotation is gradually sealed the formula endotracheal tube by dowel, plug, guard shield, hard intubate and silica gel tube constitute, it is characterized in that: guard shield is the infundibulate of rounding platform and cylinder be combined into, there are four dowels of across distribution in the plane at the place suitable for reading of guard shield, dowel holds together plug and guard shield, plug is most advanced and sophisticated plantation rubber cone down, the hard intubate is a cylindrical shape, the hard intubate is in the cylindrical portions may of guard shield, and with guard shield with threaded engagement, the lower end of hard intubate is in the silica gel tube, hard intubate and silica gel tube are the stationary fit relation, the area of plane in the space of the formed annular in top of the top of plug and guard shield is greater than the cross-sectional area of hard intubate inner space, and the diameter of the upper surface of plug is greater than the interior diameter of hard intubate.
