Description

A portable manual negative pressure suction device

Technical Field

The utility model relates to a portable manual negative pressure suction device, in particular to a medical portable manual negative pressure suction device.

Background Art

When rescuing some patients in hospitals now, opening the airway is the primary task, and keeping the airway open is a prerequisite for rescue. Respiratory secretions and invasive fluids, such as sputum, blood, water, etc., are one of the important causes of airway obstruction. When rescuing patients in hospitals, the hospital's central negative pressure suction system or electric suction device can be used in conjunction with professional tools such as suction tubes to clean the patient's airway. However, during emergency treatment outside the hospital, in the wild, and at disaster sites, the airway cannot be cleaned in time due to the lack of necessary equipment. While delaying rescue, it will also cause irreversible damage to the rescued person, and even cause the death of the rescued person. There are also two types of mechanical suction devices on the market, namely, foot-operated and suction manual suction devices, but the two types of suction devices also have many disadvantages. The foot-operated suction device is bulky and inconvenient to carry around, and is not conducive to single-person operation during emergency treatment. The suction suction device is slightly larger in size, and the overall material of the suction device is relatively hard, which is not convenient to carry around or carry in a first aid kit. Once squeezed and broken, it will be unusable, which brings many uncertainties to the rescue of patients.

Utility Model Content

The utility model aims to provide a portable manual negative pressure suction device which is convenient to carry around.

The purpose of this utility model is achieved through the following technical solutions:

The utility model is characterized in that: it comprises a negative pressure balloon, which is an elliptical soft capsule body, one end of the negative pressure balloon is provided with a suction end connecting port, the suction end connecting port is provided with a sputum suction tube, a suction end one-way valve is provided in the negative pressure balloon at the suction end connecting port, which plays a one-way conduction role, a spring is provided in the negative pressure balloon, which plays a role of restoring the balloon body after the negative pressure balloon is compressed, the other end of the negative pressure balloon is provided with a discharge one-way valve, which plays a role of one-way draining waste liquid, and a waste liquid collecting capsule body is provided on the discharge one-way valve.

The above-mentioned one-way valve at the suction end is a conical cavity composed of multiple triangular pieces, and the multiple triangular pieces can open or contract the conical cavity to play a one-way conduction role.

The scope of application of this utility model is as follows:

1. Stock it as standing supplies in the emergency department, ICU, operating room and other critical care departments of the hospital. Its main function is to be used as emergency supplies when the central negative pressure suction system in the hospital fails or there is a power outage, and it can be used to manually clean the patient's respiratory secretions.

2. It is a standing material for 120 emergency centers or pre-hospital emergency services. When going out for rescue, this product can be used to clear foreign matter from the patient's respiratory tract.

3. Package in a first aid kit or AED automatic defibrillator for emergency use.

4. It can be equipped in major rescue teams, and the product can be used to clear the patient's respiratory tract when going out for rescue.

Compared with the prior art, the utility model has a simple structure, is easy to operate, and is small in size and easy to carry. It can be operated by one person with one hand. When cooperating with medical staff to rescue the patient's oropharyngeal airway, it can quickly clear the patient's airway secretions or invasive fluids.

DETAILED DESCRIPTION

Optimal embodiment: Referring to Figures 1 to 4, the utility model includes a negative pressure balloon 4, which is an elliptical soft capsule body, a suction end connection port 2 is provided at one end of the negative pressure balloon 4, a sputum suction tube 1 is provided on the suction end connection port 2, a suction end check valve 3 is provided in the negative pressure balloon 4 at the suction end connection port 2, which plays a one-way conduction role, a spring 5 is provided in the negative pressure balloon 4, which plays a role of restoring the capsule body after the negative pressure balloon 4 is compressed, a discharge check valve 6 is provided at the other end of the negative pressure balloon 4, the discharge check valve 6 can exhaust and discharge waste liquid in one direction, and plays a role of one-way conduction of waste liquid, and a waste liquid collecting capsule 7 is provided on the discharge check valve 6; the suction end check valve is a conical cavity composed of multiple triangular pieces, and the multiple triangular pieces can open or contract the conical cavity to play a one-way conduction role; the suction end check valve is in a conical contracted state 8, and the suction end check valve is in an open state 9.

The functions of the various components of the utility model are as follows: the suction tube can be divided into two types: long and short. The material and size of the long suction tube are similar to those of the existing suction tube, and it is used to suck foreign objects deep in the airway. The short suction tube has a larger diameter and is slightly thicker, and is used to suck foreign objects in the oral cavity and throat. The short suction tube is close to the negative pressure balloon and has a hard texture, while the front section has a soft texture, and the front section opening has multiple suction ports; both long and short suction tubes can be seamlessly connected to the suction end connection port. One-way valve at the suction end: The main function of this one-way valve is to only allow foreign objects sucked into the suction tube to enter the negative pressure balloon, and not allow foreign objects in the balloon to enter the suction tube, nor allow waste gas generated when the negative pressure balloon is pressed down to enter the suction tube. Negative pressure balloon: This part is the core component for generating negative pressure. The formation of negative pressure mainly depends on the negative pressure formed when the balloon is contracted and then opened by external force. A spring is designed inside the balloon. One end of the balloon is connected to the long and short suction tubes and the one-way valve at the suction end, and the other end is connected to the one-way valve for exhaust and waste liquid discharge and the waste liquid collection capsule. Spring: The spring is installed inside the balloon. The spring is a tension spring. Its main function is to provide sufficient tensile force after the negative pressure balloon is contracted by external force, so that the negative pressure balloon can quickly return to the original state, thereby ensuring the effectiveness of forming negative pressure. One-way valve for exhaust and waste liquid discharge: The main function of this one-way valve is to only allow the exhaust gas discharged when the negative pressure balloon is pressed down and the waste liquid inhaled into the negative pressure balloon to enter the waste liquid collection capsule. When the negative pressure balloon forms negative pressure, the one-way valve will not allow gas or liquid to flow into the negative pressure balloon. Waste liquid collection bag: This part is a soft bag-shaped structure, and its opening is connected to the exhaust and waste liquid discharge one-way valve. Its main function is to collect the waste liquid sucked into the negative pressure balloon. At the same time, it can also store the waste gas discharged each time the negative pressure balloon is pressed down. When the waste liquid collection bag is full, the waste liquid collection bag can be disconnected from the exhaust and waste liquid discharge one-way valve, and then connected to the exhaust and waste liquid discharge one-way valve after the waste gas and waste liquid are discharged.
