Detailed description of the invention
below in conjunction with accompanying drawing, with embodiment, the invention will be further described.
as Figure 1-3: a kind of catheter for tracheostomy, comprise the body 1 of inner hollow, described body 1 one end is by being rotationally connected the pipe cap 2 for opening and closing of fault body 1 port, described pipe cap 2 comprises cap body 21, for blocking the choking portion 22 of body 1, described choking portion 22 offers hole A24, in described body 1, the position of corresponding choking portion 22 arranges auxiliary section 11, providing holes B12 on described auxiliary section 11; After pipe cap 2 rotates 30 ° ~ 90 °, hole A24 and hole B12 can overlap, thus ensures to be communicated with outside air in body 1.Described choking portion 22 comprises the sleeve pipe 221 being close to body 1 inwall and the blocking plate 222 be vertically installed in pipe cap 2; Described blocking plate 222 offers hole A24.Described sleeve pipe 221, cap body 21 are connected with blocking plate 222 one.Hole A24 and hole B12 can be multiple, line centered by the axis of pipe cap 2, and circumference array distributes.But hole A24 is different from the position of hole B12, after so just can be implemented in rotation angle, hole A24 and hole B12 just overlaps.Auxiliary section 11 is one piece and body 1 inner diameter plectane of the same size as can see from Figure 2, and plectane is fixedly connected with body 1.
and pipe cap 2 arranges structure how could realize freely rotating on body 1, this as can see from Figure 3, described pipe cap 2 is threaded with body 1, and the female thread 23 of described cap body 21 medial surface leaves distance H relative to top inside cap body 21.Because sleeve pipe 221 is connected with cap body 21 one, define double-decker, and the distance between two-layer is consistent with the wall thickness of the body 1 that will rotate into, while body 1 screws in female thread 23, the wall thickness of body, cap body and sleeve pipe 221 form an airtight space, body 1 constantly rotates, will constantly compress this space, form larger pressure, so the effect of locking will be formed, one is the frictional force thought between object, and two is exactly because this air pressure increases the pressure between screw thread.But our this medical apparatus and instruments is for patient trauma position, if form larger pressure, dismounting of outwarding winding is gone with regard to needing larger power, that will certainly produce and rock or shake, and also will touch wound, causes the expansion of wound or causes the pain of patient, so will distance H be left, would not produce very large space pressure like this, it is simple that the rotation of pipe cap also becomes, and makes operator not need very large power just can rotate.
in order to reduce the joint gap between choking portion 222 and auxiliary section 11, enhanced leaktightness, from Fig. 3, we can also see that described blocking plate 222 arranges sealing gasket 25 in the face of the side of auxiliary section 11, and described sealing gasket 25 offers the hole corresponding to hole A.Described auxiliary section 11 arranges sealing gasket 25 on the side of blocking plate 222, and the hole corresponding to hole B is offered in described auxiliary section 11.Sealing gasket 25 can adopt rubber sheet gasket or rubber combined pad.And be easily attached on the contact surface of object and air due to air particles, blocking plate 222 and auxiliary section 11 are primary barrier parts that blocks air circulates, so a lot of particulate matter or antibacterial can be adhered to, and sealing gasket is quick detachable easy to clean is also convenient for changing, the safe and sanitary of this catheter for tracheostomy can be strengthened like this.
the another kind of structure of choking portion 22 and auxiliary section 11 as can see from Figure 4, described choking portion 22 comprises the sleeve pipe 221 and funnelform blocking plate 22 of being close to body 1 inwall, and a side of described blocking plate 222 or dual-side offer hole A24.Described auxiliary section 11 comprises and coordinates corresponding inclined side 111 with blocking plate 222, the vertical recessed right-angle side 112 connecting inclined side 111 and body 1 inwall; Described inclined side 111 offers hole B12.Described recessed right-angle side 112 internal fixtion connects kit 4.As long as the hole A24 on blocking plate 22 rotates the B12 position, hole arrived on inclined side 111, the circulation of air just can be realized.In actual use, in air, damage ratio is comparatively serious, and weather is alternate sunshine and rain also, causes the conversion ratio of air more, so can put some desiccant in kit 4, plays desiccation.Certainly can also put some bacteria removers or the medicament to purification of air, improve the quality sucking air, accelerate patient and recover.
sometimes patient is after use catheter for tracheostomy, also needs to carry out suction sputum nursing, because with regard to the stop of choking portion and auxiliary section, sputum aspirator tube is not easy directly to insert.Can see at such as Fig. 1, body 1 is divided into two sections by this product, adopts dismountable connected mode between two sections.Screw thread 3 can be adopted to connect, and also can be that buckle connects.The point blocked must after auxiliary section 11.When wanting suction sputum like this, just can dismantle first half, sputum aspirator tube just directly can insert the second half section of body.
