The utility model provides a nasal bile duct oronasal conversion auxiliary device.

As shown in fig. 1, the nasobiliary tube oronasal conversion assisting device provided by the embodiment of the present invention comprises an injector casing 10, a guide wire 20 penetrating through the injector casing 10, and a carrier tube 30, the syringe sleeve 10 is provided with a first through hole and a second through hole at both ends along the length direction thereof, the diameter of the second through hole is smaller than that of the first through hole, the guide wire 20 comprises a collar part 21 and an operation part 22, the sleeve ring part 21 is connected with the operating part 22, the operating part 22 passes through the first through hole and then is connected with the sleeve ring part 21 to form an annular cavity 23 on one side of the second through hole far away from the first through hole, the annular cavity 23 is adapted to rest against the posterior pharyngeal wall of the oral cavity, the annular cavity 23 is adapted to receive the carrier tube 30, the operating portion 22 is movable in the extension direction of the syringe sleeve 10 to increase or decrease the area of the annular cavity 23.

In this embodiment, the nasobiliary tube oronasal conversion auxiliary device includes an injector cannula 10, a guide wire 20 and a carrier tube 30 which are arranged in the injector cannula 10 in a penetrating manner, a first through hole and a second through hole are formed at two ends of the injector cannula 10 along a length direction thereof, an aperture of the second through hole is smaller than an aperture of the first through hole, the guide wire 20 includes a collar portion 21 and an operation portion 22, the collar portion 21 is connected with the operation portion 22, the operation portion 22 penetrates through the first through hole and then is connected with the collar portion 21 to form an annular cavity 23 which is located at one side of the second through hole far away from the first through hole, the annular cavity 23 is used for being supported on a pharyngeal rear wall of an oral cavity, the annular cavity 23 is used for sleeving the carrier tube 30, the operation portion 22 can move along an extending direction of the injector cannula 10 to increase or reduce an area of the annular cavity 23, the guide wire 20 is a 60cm medical zebra guide wire, and a layer of plastic film is arranged on the guide wire 20.

When the nose and mouth switching is carried out on the nose bile duct, one end of the nose bile duct is placed in the biliary tract, the other end of the nose bile duct is led out from the oral cavity, the operation part 22 is stretched along with the operation part 22, so that the operation part 22 moves in the injector sleeve 10, the area of the annular cavity 23 can be reduced in the moving process, the guide wire 20 can enter the oral cavity more smoothly, when the guide wire 20 is inserted into the throat from the oral cavity and is abutted against the rear wall of the pharynx, the area of the annular cavity 23 can be increased by stretching the operation part 22, so that when the carrier tube 30 enters the throat from the nasal cavity, the carrier tube 30 can be ensured to be positioned in the sleeve ring part 21, and then after the carrier tube 30 is pulled out from the oral cavity through the guide wire 20 and is connected with the end part of the nose bile duct outside the oral cavity, the mouth and nose switching of the nose bile duct can be completed by pulling the carrier tube 30 out from the nasal cavity, and the efficiency of the nose and mouth switching can be obviously improved, reducing the patient's response. Specifically, in the present embodiment, one end of the guide wire 20 is first passed through the first through hole and the second through hole, and then bent and then passed through the second through hole and the first through hole again, so that the two ends of the guide wire 20 are aligned to form the collar portion 21, and the minimum distance of the collar portion 21 in the width direction of the syringe sleeve 10 is smaller than the through hole of the second through hole, thereby further preventing the collar portion 21 from retracting into the syringe sleeve 10 when in use, and causing the occurrence of the mouth-nose switching failure.

In addition, in the embodiment, the injector sleeve 10 is sleeved outside the guide wire 20, so that when the carrier tube 30 is sleeved and taken out through the guide wire 20, the guide wire 20 does not slide, the carrier tube 30 can be stably sleeved and taken out through the guide wire 20, the oronasal conversion efficiency of the nasal bile duct is improved, the guide wire 20 is fixed by the injector sleeve 10, and the cost of the oronasal conversion of the nasal bile duct can be effectively reduced.

Wherein, the capacity of the syringe sleeve 10 is one of 1ml, 2.5ml, 5ml and 10ml, in a preferred embodiment, the capacity of the syringe sleeve 10 is selected to be 1ml, because the length of the syringe sleeve 10 with the capacity of 1ml is longer, so that the syringe sleeve 10 with the capacity of 1ml has enough length to reach the pharyngeal wall of a patient, and the diameter is smaller, when the guide wire 20 passes through the syringe sleeve 10, the fixation of the guide wire 20 is facilitated, the guide wire 20 is easier to control during operation, the syringe sleeve 10 with the smaller diameter can pass through the oral cavity more smoothly, and the syringe sleeve 10 with the smaller diameter can be finely adjusted in the oral cavity due to the smaller diameter after passing through the oral cavity, so that the use is more flexible. And the syringe sleeve 10 belongs to a common disposable device in clinic, and can be conveniently obtained when in use, and the cost for fixing the guide wire 20 by adopting the syringe sleeve 10 is obviously lower than that for fixing the guide wire 20 by other auxiliary devices in the application.

Meanwhile, the carrier tube 30 is provided with a side hole 31, a cavity is arranged inside the carrier tube 30, and the carrier tube 30 can be connected with the nasobiliary tube more conveniently by arranging the side hole 31. Furthermore, the carrier tube 30 is made of rubber and has smooth ends, so that irritation to the nasal mucosa is small.

The above only is the preferred embodiment of the present invention, not so limiting the patent scope of the present invention, all under the concept of the present invention, the equivalent structure transformation made by the contents of the specification and the drawings is utilized, or the direct/indirect application is included in other related technical fields in the patent protection scope of the present invention.
