Double-sleeve aspiration tube capable of preventing aspiration by mistake

Abstract

The utility model relates to the technical field of medical instruments, and discloses an anti-aspiration double-sleeve suction tube which comprises an inner sleeve and an outer sleeve arranged outside the inner sleeve in a sleeving mode. A through hole is formed in the outer side wall of one end of the inner sleeve; a lengthened side hole and a suction hole are formed in the outer side wall of one end of the outer sleeve, a pressure reducing hole is formed in the end, away from the lengthened side hole, of the outer side wall of the outer sleeve, and the inner sleeve and the outer sleeve are connected and tightly sleeved through a bolt piece. According to the double-sleeve suction tube capable of preventing aspiration by mistake, the tube wall of the outer sleeve made of silica gel can be squeezed and shrunk, and the lengthened side hole formed in the outer wall of the outer sleeve can be expanded to support a spherical bag due to the fact that the formed hole is long, so that a suction cavity can be enlarged, complex sputum or secretions are prevented from excessively blocking the through hole, and the pressure reduction area is increased; and the decompression hole can prevent the tissue damage caused by overlarge negative pressure when the lengthened side hole is blocked, so that the device is safer and more reliable.

Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a double-cuff suction tube to prevent mis-absorption. Background Art

[0002] The suction tube is a clinical oral surgery auxiliary instrument with a suction head at the front end being a cylindrical cavity structure, an arc-shaped bottom, and suction holes evenly distributed on the annular wall. It is generally used in conjunction with braces clamps.

[0003] When providing medical assistance to some patients with aspiration pneumonia, the compression of the root of the tongue and the contraction of the muscles in the throat often lead to closure or compression of the patient's trachea. Problems such as aspiration pneumonia or lung infection are often accompanied by the accumulation of secretions such as sputum in the patient's respiratory tract. Therefore, a suction tube is often required to assist in decompression and to suction and clean secretions such as sputum. However, the compression of the root of the tongue and the contraction of the muscles in the throat often lead to closure or compression of the patient's trachea, which may also squeeze the outer wall of the existing commonly used suction tube and cause closure. There is still a certain risk. Therefore, a double-cuff suction tube to prevent accidental aspiration is proposed to solve the above problem. Utility Model Content

[0006] A through hole is formed on the outer wall of one end of the inner sleeve;

[0007] An extended side hole and a suction hole are provided on the outer side wall at one end of the outer sleeve, a pressure reducing hole is provided on the outer side wall of the outer sleeve away from the extended side hole, and the inner sleeve and the outer sleeve are connected and tightened by bolts.

[0008] Preferably, one end of the inner sleeve away from the through hole is through-set for connecting to an external suction device.

[0009] Preferably, the inner sleeve is made of PVC material.

[0010] Preferably, the outer sleeve is made of silicone material.

[0011] Preferably, a plurality of the extended side holes are provided, and the plurality of the extended side holes are distributed in a circular array at the end of the outer side wall of the outer sleeve.

[0012] Preferably, developing marks are provided on the outer side wall of the outer sleeve at both ends of the extended side hole.

[0013] Preferably, an internal thread joint having the same material as the inner sleeve is fixedly connected to the end of the outer sleeve away from the extended side hole, and the bolt member is provided with an external thread, and the bolt member is threadedly connected to the internal thread joint.

[0014] Preferably, the bolt member is hollow inside, the bolt member is sleeved on the outside of the inner sleeve, the inner hole of the bolt member is a tapered hole, and a shrinkage notch is provided on the threaded surface of the bolt member.

[0015] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0016] First, the utility model measures the length from the nostril and the mandible to the Adam's apple, and then the inner sleeve and the outer sleeve are assembled, the inner sleeve and the outer sleeve end are glued and connected, the bolt is locked, the shrinkage notch shrinks, and the inner sleeve is locked from the inside to achieve the purpose of fixing the inner sleeve and the outer sleeve, paraffin oil is coated on the outside of the outer sleeve, and it enters the respiratory tract through the nostrils and is inserted into the designed depth, and then the bolt is loosened and pushed forward. Since the inner sleeve and the outer sleeve end are glued and connected, the tube wall of the silicone outer sleeve will be squeezed and contracted, and the position of the extended side hole opened at the outer wall of the outer sleeve will be stretched due to the longer hole, and a spherical capsule will be propped up, so that the suction chamber can be expanded, and the through hole can be prevented from being excessively blocked by complex sputum or secretions, and the decompression area can be increased, and the decompression hole can prevent excessive negative pressure from causing tissue damage when the extended side hole is blocked, which is safer and more reliable.

[0017] Second, the development mark of the utility model is used to locate the balloon formed by the extended side hole of the outer sleeve during X-ray examination, which is convenient and safe. BRIEF DESCRIPTION OF THE DRAWINGS
