Description

multifunctional nasal plug

technical field

The utility model relates to a medical device, in particular to a medical multifunctional nasal plug.

Background technique

Often need to inhale oxygen or carry out oxygen treatment to patient in hospital, existing oxygen supply device has two kinds, and a kind of is nasal cannula, and another kind is common nasal obstruction.

Nasal cannula is a simple and practical method that can most stably increase the concentration of inhaled oxygen. As shown in Figure 8, a rubber tube or catheter with a soft texture and a porous front end (to disperse the force of the airflow and protect the mucous membrane) with an inner diameter of 2 mm is generally used. The tube is slowly inserted through one nostril to the level of the soft palate, about 8 to 10 cm deep, fixed with adhesive tape and given oxygen. Its advantages are: simple structure, easy to use and patient tolerance, etc. It is still the most commonly used oxygen delivery device. Its disadvantages are as follows: ①Two nostrils need to be used alternately; ②It is not suitable for bilateral nasal cavities to receive oxygen therapy at the same time; ③The nasal cannula has a strong stimulating effect on the nasal cavity of the patient; Chances of mucus blockage in the airways. ⑤ It needs to be fixed with adhesive tape.

Ordinary nasal congestion has two types: unilateral or bilateral. The basic structure of unilateral nasal congestion is shown in Figure 9-A. The basic structure of the bilateral nasal congestion is shown in C and D of Figure 9. The oxygen supply conduit 7 communicates with the bilateral nostril conduits. There is no intermediate partition inside the nasal plug connector, and there is no control device for the oxygen supply conduit. Its advantages are: easy connection and use, simple fixing device, two nostril catheters for both sides of the nostrils, without affecting oral care and eating, compact design, and convenient use. Its disadvantages are as follows: ① Most of the unilateral nasal congestion (as shown in Figure 9 B) has no fixing device, and it needs to be pasted with adhesive tape when using it, so the patient feels obvious discomfort when it is removed; ② When using ordinary nasal congestion for oxygen therapy, it cannot Simultaneous _{PET CO2} monitoring and inhaled drug therapy. If a critically ill patient needs to monitor _{PET CO2} at the same time, it is necessary to use one-sided nasal congestion for oxygen therapy, and place the sampling tube 51 of the _CO2 monitor directly in the vestibule or nasal cavity of the other side and fix it with adhesive tape, as shown in the figure 10 Schematic diagram of simultaneous application of oxygen therapy for unilateral nasal congestion and _{PET CO2} monitoring. If the patient uses bilateral common nasal congestion for oxygen therapy, the oxygen therapy needs to be suspended during _PET CO ₂ monitoring and inhaled drug therapy; When people use a higher oxygen flow rate, because the airflow speed is faster, it has an irritating effect on the patient's nasal cavity, and the patient's discomfort is obvious; ④The model is single, mostly two models, so it is not suitable for infants and oversized adults. People; 5. usually made of hard plastic, which can cause oppression to the nostrils, and should not be used for a long time, especially when the common nasal plug model used is relatively large.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies and defects of the prior art, and propose a multifunctional nasal plug, which has complete models, easy connection and use methods, special fixing devices, and different nostril catheters for bilateral nostrils. In case of interruption of oxygen therapy, PET _{CO 2} monitoring and drug inhalation therapy were performed.

In order to achieve the above object, the utility model adopts the following technical solutions.

A medical multifunctional nasal plug, which comprises:

A multifunctional nasal plug connector, the main body of which is a hollow tubular structure made of soft rubber with a certain hardness. On one side, there are two nostril catheters inserted into the patient's bilateral nostrils. There is a partition inside the main body, which can hold the main body The lumens are separated from each other. On the other side of the main body, there is a multi-functional special joint, which communicates with one of the nostril catheters. There is a cap plug on the head of the multi-functional special joint, and two ends at the two ends of the main body lumen. an oxygen supply port, respectively connected to the distal ends of the two oxygen supply catheters;

Two oxygen catheters, which are hollow catheters made of soft plastic;

A three-way control device, on which there are two interfaces, which are respectively connected to the proximal ends of the two oxygen supply catheters, and the other interface is connected to the gas supply pipe of the oxygen supply device, which can be realized by rotating the switch of the three-way control device Bilateral or unilateral nostril oxygenation;

A fixing device, which is a movable tubular structure, is set outside the two oxygen supply conduits and can move on the two oxygen supply conduits.

The length of the nostril catheter is 5-10 mm.

The front end of the catheter for one nostril is in the shape of a round blunt catheter with an outer diameter of 2 to 3 millimeters.

The front end of the other nostril catheter is blunt and spherical, and the outer diameter of the ball is 4-9 mm.

The cap plug is connected with the head of the multi-functional special-purpose joint through an inserting luer lock structure, so as to close the opening of the multi-functional special-purpose joint.

The other interface of the three-way control device is connected with the gas supply pipe of the oxygen supply device through a detachable Luer lock structure.

The length of each oxygen supply catheter is 50-60 centimeters.

The distal end of the oxygen supply catheter is permanently fixedly connected with the joint ports at both ends of the main body lumen.

The proximal end of the oxygen supply catheter is also permanently fixedly connected to the two interfaces of the three-way control device.

Advantage of the utility model:

1. The method of connection and use is simple, and the entire operation process can be completed within 5 seconds.

2. All models, small, medium, large and special are suitable for infants, children, normal adults and larger adults respectively.

3. Equipped with a special fixing device, no need to use the traditional tape sticking method, and the patient will not feel uncomfortable when it is removed. In addition, this fixation method is also suitable for patients with prone to skin damage, such as epidermolysis bullosa and burn patients.

4. Different nostril catheters are used for both sides of the nostril. The nostril catheter 1 is thinner and the front end is round and blunt. Therefore, long-term use is more comfortable for patients and less damage to the mucosal tissue of the nasal vestibule. The front end of the nostril catheter 2 is spherical and has different outer diameters, so it can be closely combined with the patient's nostril wall. In addition, the connection between the nostril catheter 2 and the oxygen supply device can be blocked by the three-way control device, so the outside world Gases interfere slightly with sampling for _CO2 monitoring.

5. Since nostril catheters 1 and 2 are only located in the patient's nasal vestibule and have a relatively thick inner diameter, it can reduce the damage to the nasal mucosa caused by high-speed oxygen flow, and the oxygen supply effect is not affected by turbinate hypertrophy and nasal septum distortion, and is rarely used The secretions are clogged and there is no rebreathing problem. In addition, it does not affect oral care and eating.

6. Drug inhalation therapy can be performed without interrupting oxygen therapy, which is of great clinical significance in the emergency treatment of critically ill patients. In addition, since the drug is directly delivered into the nasal cavity, the therapeutic effect of inhalation administration is good.

7. Compact design, small footprint.

8. The manufacturing material is simple and the price is cheap.

9. The luer lock connection device is used in the device, which is not only tightly connected and reliable, but also very quick and easy to disconnect, and can be connected with the gas pipelines of many current oxygen supply devices.

10. The three-way switch is used as the control device, so it is very convenient to change the use mode.
