Description

A catheter device for nasal ventilation

technical field

The utility model relates to a ventilation device, in particular to a catheter device for nasal ventilation, which is mainly suitable for auxiliary ventilation and belongs to the technical field of medical equipment.

Background technique

Ventilation management is now essential in the medical sector, especially during surgery. For patients during surgery, the main ventilation methods include endotracheal tubes, laryngeal masks, masks, etc. For patients with minor operations, the implanted endotracheal tube and laryngeal mask are more or less irritating, resulting in unnecessary complications, such as hoarseness, laryngospasm, and hypercapnia. In the case of spontaneous breathing, the patient can inhale oxygen through the face mask. Although it can reduce postoperative complications, it is not conducive to monitoring the end-tidal partial pressure of carbon dioxide, tidal volume, and input of anesthetic gas. Therefore, for patients undergoing minor surgery and retaining spontaneous breathing, the endotracheal tube and laryngeal mask will bring unnecessary stimulation and complications, and the mask cannot monitor and provide anesthesia gas inhalation more safely. At present, with the improvement of anesthesia technology, more and more patients under general anesthesia (especially children) can perform surgery without consciousness and pain while retaining spontaneous breathing. With the improvement of anesthesia technology, we can become more and more It does not rely on the implanted laryngeal mask and endotracheal tube, which can reduce the time of inserting the laryngeal mask or endotracheal tube and the corresponding damage, but at the same time, we must also retain its monitoring and ventilation functions.

Utility model content

The purpose of this utility model is to provide a catheter device for nasal ventilation in order to overcome the shortcomings of the above-mentioned prior art. It allows patients undergoing short operations to meet the requirements of intraoperative monitoring of breathing, assisted breathing, and inhalation of anesthetic gas while reducing throat irritation while retaining spontaneous breathing.

The technical scheme of the utility model is as follows:

A catheter device for nasal ventilation. The device includes a hollow catheter. One end of the hollow catheter is communicated with a gas input joint, and the other end is communicated with a gas output tube.

Further, in the catheter device for nasal ventilation, a circular platform may be provided on the hollow catheter, and the diameter of the circular platform is larger than that of the hollow catheter and coaxial with the hollow catheter.

Further, the catheter device for nasal ventilation has two gas output tubes.

Further, in the catheter device for nasal ventilation, the gas output tube can be bent naturally while keeping the inside of the tube unobstructed.

Further, in the catheter device for nasal ventilation, the nasal plug is made of elastic material.

Further, in the catheter device for nasal ventilation, the end of the gas input joint is threaded.

The internal diameter and length of each part of the catheter device for nasal ventilation provided by the utility model can be designed with different types of internal channels according to the size of the nasal cavity entrance, and the outer diameter of the gas output joint is slightly smaller than the internal channel of the nostril entrance. The inner diameter and length of the hollow catheter can be appropriately reduced to reduce the relative ventilation dead space.

The beneficial effects of the utility model are: the catheter device for nasal ventilation is easy to use, only need to plug the nasal plug into the entrance of the nostril to make the patient close the mouth, and the gas input joint can be connected to the threaded pipe joint of the anesthesia machine or the ventilator. It can meet the functions brought by the laryngeal mask or endotracheal tube at the same time: input anesthetic gas, monitor end-tidal carbon dioxide partial pressure, tidal volume, etc.; if necessary, press and fasten the mouth to perform manual assisted breathing; the device's The relative dead space can be smaller than the dead space caused by the laryngeal mask and endotracheal tube, that is, it can better reduce the repeated absorption of carbon dioxide, and at the same time eliminate the operation time, stimulation and Corresponding postoperative complications.

detailed description:

The catheter device for nasal ventilation provided by the present invention will be further described below in conjunction with the accompanying drawings.

Example 1

As shown in Figure 1, the schematic diagram of the catheter device for nasal ventilation provided in this embodiment includes a hollow catheter 1. One end of the hollow catheter 1 is connected with a gas input joint 2, and the other end is connected with a gas output tube 3. The gas output The end extension tube outside of pipe 3 is provided with the nasal plug 4 that communicates in. The number of gas output pipes 3 is two, which are respectively connected to two nostrils of a person during use; the end of the gas input connector 2 is threaded to facilitate connection with gas input devices, detection devices, etc. during use.

Put the gas output tube 3 into the two nostrils of the user during use, and adjust the nasal plug 4 arranged outside the end of the gas output tube 3 to ensure that the air flow completely flows in and out from the gas output tube 3 during the normal breathing process of the user , to avoid leaking from the gap between the nasal cavity inner wall and the gas output tube 3. The user can fully use nasal breathing ventilation simply by closing the mouth. The gas input connector 2 can be connected to the threaded pipe connector of the anesthesia machine or ventilator, and at this time, it can meet the functions brought by the laryngeal mask or the endotracheal tube: input anesthetic gas, monitor end-tidal carbon dioxide partial pressure, tidal volume, etc.; if necessary Pressing and fastening the mouth can also perform manual assisted breathing; the relative dead space of the device can be smaller than that caused by the laryngeal mask and endotracheal tube, which can better reduce the repeated absorption of carbon dioxide and prevent The operation time, stimulation and corresponding postoperative complications brought about by the insertion of laryngeal mask and endotracheal tube into the mouth.

Example 2

As shown in Figure 2, it is a schematic diagram of the catheter device for nasal ventilation provided by the present embodiment, wherein an improvement is made on the basis of Embodiment 1, a circular platform 5 is arranged on the hollow catheter 1, and the diameter of the circular platform 5 is larger than The diameter of the hollow conduit 1 is set coaxially with the hollow conduit 1, and the setting of the circular platform 5 facilitates the taking of the entire device, and at the same time facilitates the connection of the device with other equipment. In this embodiment, the gas output tube 3 can be bent naturally under the condition of keeping the inside of the tube unobstructed, so as to reduce the extrusion on the inner wall of the nostril and ensure the comfort of the user during use; the nasal plug 4 is made of elastic material to ensure the comfort of use and tightness.

The catheter device for nasal ventilation provided by the utility model is suitable for medical procedures capable of spontaneous breathing, avoiding the damage and discomfort to the throat caused by the commonly used implanted laryngeal masks and tracheal catheters, and is especially suitable for the treatment of children.
