Problems solved by technology

[0003] For patients under general anesthesia, it is necessary to use a laryngoscope to observe the position of the intubation during rescue and intubation. It is troublesome and difficult to perform laryngoscope and intubation at the same time For the headlight problem, the present invention provides a rescue composite intubation catheter to meet the needs of intubation in the state of blind insertion. Regardless of whether the inner end of the intubation tube enters the trachea or esophagus, the sleeve relationship of the inner tube in the outer tube can be manipulated. Realize the switching of stomata to ensure the connection between the trachea and the ventilator

Embodiment 1

[0022] Embodiment 1: a kind of as figure 1 As shown in the rescue composite intubation catheter, the catheter assembly mainly includes an outer tube and an inner tube, the inner tube can be assembled into the outer tube for use, and the outer section of the inner tube is connected to the ventilator connector 21 .

[0023] From figure 2 It can be seen from the figure that the outer tube 1 includes a thick-diameter section 1-1 located at the outer end and a thin-diameter section 1-2 located at the inner side. The inner diameter of the thick-diameter section 1-1 is obviously larger than the outer diameter of the inner tube. There is an annular fit gap between them. From image 3 It can be seen that the inner diameter of the narrow diameter section 1-2 is approximately equal to the outer diameter of the inner pipe, so that after the inner pipe is inserted into the thin diameter section 1-2, the two can be matched and bonded together without air leakage.

[0024] The inner end ...

Embodiment 2

[0029] Embodiment 2: another kind of salvage composite intubation catheter, such as Figure 5 As shown, the catheter assembly mainly includes an outer tube and an inner tube, which are used after being fitted.

[0030] Wherein, the outer tube 1 includes a thick-diameter section 1-1 located at the outer end and a thin-diameter section 1-2 located at the inner side, an upper airbag 2 is arranged at the inner end of the thick-diameter section 1-1, and an upper air bag 2 is arranged at the inner end of the thin-diameter section 1-2. The lower air bag 3 is set, the lower side position of the upper air bag 2 is provided with the upper air hole 5 of the outer tube, and the lower side position of the lower air bag 3 is provided with the lower air hole 13 of the outer tube. The upper airbag 2 is connected with the upper airbag air delivery tube 9, and the lower airbag 3 is connected with the lower airbag air delivery tube 10. The upper airbag air delivery tube 9 and the lower airbag air ...

Embodiment 3

[0034] Embodiment 3: The above embodiment 1 and embodiment 2 realize the installation of the inner and outer tubes by turning over the rails, and then realize the selective blocking and opening of the two air holes. One is to overlap the front and back holes, and the other is to open and close the hole by pushing the core rod to open and close the self-closing hole cover at the bottom.

[0035] However, there may be some problems in Example 1 and Example 2 above. For patients under general anesthesia, because analgesics and muscle relaxants are used, breathing will disappear after use. After all, there is not much time for endotracheal intubation. During the procedure, the patient does not receive oxygen into the lungs. It takes time and delicate operation to pull out and reload the rails. This operation can meet the requirements smoothly, but in rare cases, the rail change operation is unsuccessful at one time, and it needs to be pulled out again, which will take more time. ...

Abstract

The invention discloses a rescue composite intubation catheter. An outer tube comprises a large-diameter section located at the outer end and a small-diameter section located on the inner side; an upper air bag is arranged at the inner end of the large-diameter section; a lower air bag is arranged at the inner end of the small-diameter section; an outer tube upper air hole is formed in one side ofthe lower tube wall of the upper air bag; a self-sealing cover is arranged at the lower side port of the lower air bag and is used for sealing the port; an inner tube upper air hole is formed in oneside of the middle tube wall of an inner tube; an inner port of the inner tube is open; an inner section of the inner tube can be tightly attached to the small-diameter section of the outer tube in amatched and sleeved mode; and a guide mechanism is arranged between an outer section of the inner tube and the large-diameter section of the outer tube. According to the rescue composite intubation catheter, intubation can be achieved in a blind insertion state, and no matter whether the inner end of an intubation tube enters the trachea or the esophagus from the outside, switching of the air holes can be achieved by operating a sleeving relation of the inner tube in the outer tube, so that it is guaranteed that the trachea communicates with a breathing machine. The operation is simple, and precious rescue time is ensured not to be delayed due to accidents in the operation process.

Description

technical field [0001] The invention belongs to the technical field of rescue supplies for patients under general anesthesia, and in particular relates to a composite intubation catheter for rapid adaptation for general anesthesia rescue. Background technique [0002] For patients under general anesthesia, because analgesics and muscle relaxants are used, the breathing will disappear after use, so we will intubate the trachea through the mouth in clinical practice, and connect the ventilator outside. The intubation of the patient during the rescue requires a laryngoscope (the patient is not breathing during the rescue, and intubation is required for ventilation, and the patient’s muscles are stiff and difficult to operate. Currently, the intubation can only be performed under the condition of laryngoscope observation), which can expose the epiglottis and The glottis can only be intubated after that. Generally, it is more accidental during the rescue. The laryngoscope is not ...
