Abstract
The invention relates to an auxiliary device for retention nasal cannula conducting conversion between the mouth and the nose, comprising a nasal cannula (1) and nasal cannula traction device. The nasal cannula traction device consists of a tongue depressor (2), a traction line (3) and a traction line pushing-pulling button (4), wherein the tongue depressor is divided into a tongue depressor body part (2.1) and a tongue depressor extending part (2.2), and a traction line groove is arranged at the front edge of the tongue depressor extending part; a traction line channel and a traction line pushing-pulling button chute (2.3) are arranged at one side of the tongue depressor body part; one end of the traction line (3) is fixed at the blind end of the traction line groove, the other end of the traction line (3) passes through the traction line channel so as to be fixed at the traction line pushing-puling button (4); the nasal cannula (1) penetrating into a traction line loop (3.1) is clamped by pushing and pulling the traction line pushing-pulling button (4), and is drawn out of the mouth so as to be linked with the nasal cannula, namely, the conversion between the mouth and the nose of the nasal cannula can be conducted normally. Due to the auxiliary device, the conversion between the mouth and the nose of the nose cannula is rapid, and the success rate is high, and the possible risk in the mouth-nose conversion operation can be avoided.
Description
Technical field
The present invention relates to technical field of medical instruments, is a kind of auxiliary device of row mouth and nose conversion when keeping somewhere nose bile duct.
Background technology
Clinically, during antidromicity ERCP (ERCP), often need to keep somewhere nose bile duct and carry out biliary drainage in the bile duct under the scope of being expert at the part patient.When keeping somewhere nose bile duct, place in the biliary tract through the end of digestive tract with nose bile duct with duodenoscope by the oral cavity earlier, the other end is stayed outside the oral cavity, through the mouth and nose conversion nose bile duct is drawn from nasal cavity, to alleviate the uncomfortable degree that patient keeps somewhere nose bile duct again.When the mouth and nose conversion of carrying out nose bile duct, common way is: have certain elastic nose conduit one end with one and be inserted in the oral cavity from nasal cavity, the reuse hands it is pulled out from the oral cavity and with stay extrabuccal nose bile duct and dock, an end that just an end of nose bile duct is inserted the nose conduit is connected mutually, tractive is stayed the outer nose conduit other end of nasal cavity and the nose conduit is extracted out from nasal cavity then, nose bile duct promptly goes to nasal cavity with the nose conduit by the oral cavity and stretches out from nasal cavity, nose bile duct one end is extracted from the nose conduit, thereby finished the mouth and nose transformation process.The difficult point of nose bile duct mouth and nose conversions is inserting of nose conduit one end and from the taking-up in oral cavity: 1) the nose tube insertion depth is difficult for grasping, and crosses may touch glottis deeply and cause choking and cough even the laryngospasm equivalent risk; 2) end of nose conduit is a fingerhold from the taking-up usefulness in oral cavity, palmistry is excessive for the oral cavity, and operating difficulties needs patient to cooperate and magnifies mouth, operating time has been grown the misery that can increase patient, if patient can not tolerate and the operator's finger that bites possibly when shutting up in the operation.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, easy to use, auxiliary device that can conveniently carry out nose bile duct mouth and nose conversions.
The present invention includes nose conduit and the traction apparatus of nose conduit.The smooth conduit that the nose conduit is a good springiness, hardness is moderate, external diameter is little than the aperture, nostril, can be existing hollow tubing conductor, also can be solid for body, the conduit of head hollow, its head circle is blunt, the inner chamber of hollow is used for firmly being connected with nose bile duct, the outer wall of nose catheter shaft is provided with two graduation marks, the 1st graduation mark of nearly head to the length of apical head is about the nostril mouth to the distance of pharyngeal cavity or short slightly, and the 2nd graduation mark of head far away to the length of apical head is equivalent to the nostril mouth to the distance of glottis or short slightly; The traction apparatus of nose conduit is made up of spatula, draught line and draught line push-and-pull key, spatula divides spatula body and spatula extension two parts, the spatula body is cuboid, the spatula extension is the extension forward of spatula body, the spatula extension is convexly curved, the physiological flexibility coupling of its flexibility and root of the tongue portion, the leading edge of spatula extension is curved, is provided with the draught line groove; One side of spatula body is provided with draught line passage and draught line push-and-pull key chute, the draught line passage is embedded in the body wall of spatula body, the front end of draught line passage joins with the draught line groove of spatula extension leading edge and communicates, the tail end of draught line passage joins with draught line push-and-pull key chute and communicates, and draught line push-and-pull key places in the draught line push-and-pull key chute; One end of draught line is fixed in the draught line groove cecum of spatula extension leading edge, the draught line passage that the draught line other end passes the spatula body along the draught line groove is fixed in draught line in the draught line push-and-pull key chute to be stretched and draws key, draught line has certain tension force, when draught line push-and-pull key pushes away before draught line push-and-pull key chute, draught line is before pushed away, the draught line that is positioned at spatula extension leading edge forms the arc lasso forward, this lasso is used to entangle the nose conduit, if the nose conduit is penetrated in this lasso, post-tensioning draught line push-and-pull key tightens up draught line again, the nose conduit just is clipped between draught line and the draught line groove, can clamp by the cue conduit.
During use, insert nose bile duct routinely, nose bile duct one end is stayed outside the oral cavity, select the auxiliary device of the nose bile duct mouth and nose conversion of respective model for use according to patient's difference, operation as follows then: 1) through the oral cavity spatula extension leading edge of nose conduit traction apparatus is placed oral cavity and ccavum oropharygeum intersection, 2) the preceding draught line push-and-pull key that pushes away makes draught line form the draught line lasso in spatula extension leading edge; 3) the nose catheter head is inserted nostril and to sentence supravasal the 2nd graduation mark of nose be that labelling is inserted to ccavum oropharygeum with the nose catheter head and stretches in the draught line lasso in the nostril; 4) post-tensioning draught line push-and-pull key tightens up draught line cue conduit and clamps; If the nose catheter head fails to extend in the draught line lasso, then draught line is stretched and is drawn bond energy to move the end to along chute when the post-tensioning draught line, illustrate that lasso do not clamp the nose conduit, so just nose conduit the 1st graduation mark is fallen back and locate to the nostril, be that labelling is inserted to ccavum oropharygeum with the nose catheter head and stretches in the draught line lasso with supravasal the 2nd graduation mark of nose again, clamp the nose conduit until draught line, so repeatable operation gets final product success 2～3 times usually; 5) traction apparatus of nose conduit is withdrawed from from the oral cavity, so that the nose conduit is pulled out the oral cavity; 6) extrabuccal nose bile duct end being inserted nose catheter head inner chamber fixes; 7) withdraw from the nose conduit from nasal cavity routinely, pull out nose bile duct thereupon, thereby finish the mouth and nose conversion of nose bile duct.
The present invention is simple in structure, and is easy to use, makes the mouth and nose conversion of nose bile duct become quick, success rate is high, has alleviated patient's misery and operator's workload, the risk of having avoided existing mouth and nose conversion art to occur.
