Background technique

In the treatment of cerebral hemorrhage, intracranial pressure should be reduced and cerebral edema should be controlled to prevent brain herniation, increased blood pressure should be reduced to prevent further bleeding, and the airway should be kept open, and secretions or vomit in the airway should be sucked out at any time. Therefore, we need to use a suction tube to suck out the sputum in the patient's trachea. Of course, in addition to cerebral hemorrhage and other diseases that require the use of sputum suction tubes, other diseases such as meningitis and pneumonia also require the use of sputum suction tubes. After suctioning, in order to detect whether the patient has bacterial infection, the sputum is often tested. The commonly used sputum suction tubes on the market do not have the function of collecting sputum. If you want to collect sputum, you need to connect the suction tube to a special sputum collector. This is not convenient to use, and you need a special sputum collector. To collect, the cost is relatively high.

detailed description

The present invention will be further described below with reference to the accompanying drawings and examples, and the embodiments of the present invention include but not limited to the following examples.

Example 1

As shown in Figure 1, the disposable controllable sputum collection type suction tube includes a suction tube, one end of the suction tube is connected with a flow regulating head, and the other end is a suction end extending into the trachea. The flow regulating head is used for connecting with a negative pressure suction device.

The sputum suction tube includes a first tube 1, a second tube 2 and a third tube 3, the second tube is connected with the first tube and the third tube respectively, and one end of the first tube is connected with the flow regulating head 4 , one end of the third tube is the suction end 31.

One end of the third tube where the sputum suction end is located is closed and presents an arc. The wall of the third tube where the sputum suction end is located is provided with several sputum suction ports for sputum suction. This structure makes it difficult to cause damage to the patient's trachea after being inserted into the trachea.

Both ends of the second tube are also provided with one-way flaps 21, and the two one-way flaps are opened when there is negative pressure, and the sputum flows from the suction end to the flow regulating head; , the one-way flap is closed, and the second tube remains relatively closed. Allow the second tube to collect sputum.

Two funnel-shaped structures 23 are also arranged in the pipe body at both ends of the second pipe. The orientations of the two funnel-shaped structures are exactly the same, and the small-diameter ports of the funnel-shaped structures are all facing the flow regulating head. between the funnel-shaped structures. The funnel-shaped structure reduces the flow rate to a certain extent, making sure that there will be no backflow. The funnel-shaped structure is also convenient for squeezing the tube wall by hand when the second tube is cut out separately, which can make the flow of sputum flow small and easy to control.

The one-way valve is a structure of a duckbill check valve, and the one-way valve includes a first valve and a second valve, and one end of the two valves is fixedly connected to the inner wall of the second tube, and the two valves are fixedly connected to each other. The other end overlaps and fits, so that a pointed duckbill is formed, and the size of the first valve is larger than the size of the second valve, so that overlapping and fitting can be realized to avoid backflow; the pointed duckbill Parts are all facing the flow regulating head. When the negative pressure suction device is turned on, the pressure of the second tube and the third tube is greater than the pressure of the first tube, the sputum is sucked out and the sputum is squeezed out of the position where the first valve and the second valve overlap and fit, so that the sputum When the vacuum suction device is closed, the pressure is the same, and even if the sputum has a back pressure, because the size of the first valve is larger than the size of the second valve, the circuit is completely sealed, which is similar to a heart valve principles and functions.

In this embodiment, the third tube is covered with an elliptical elastic part 5, so that when the sputum suction tube starts to suck sputum, the elliptical part does not support the inside of the patient's mouth, preventing the patient's mouth from occluding. Suction affects.

In this embodiment, the sputum suction tube is provided with a scale, so that medical personnel can easily know the depth of the sputum suction tube extending into the trachea.

In this embodiment, the outer walls of both ends of the second tube are connected with caps 22, and the one-way flap is located between the two caps. The cap includes an elastic connector connected to the outer wall of the second tube and a cap connected to the elastic connector, so that when the second tube is cut off by the scissors, the second tube can be covered with the cap. Hygienic and easy transfer to the laboratory.

In this embodiment, the first tube, the second tube and the third tube are integrally formed.

When in use, the medical personnel connect the negative pressure suction device, and then do not close the vent hole of the flow regulating head, so that negative pressure cannot be generated, and then extend the suction tube into the patient's trachea, and then judge the amount inserted according to the scale. Due to the smooth suction end, the patient's trachea will not be damaged, slide the elastic part into the patient's mouth, let the patient bite, and support the patient's upper and lower jaws. Then block the vent hole of the flow adjustment head, generate negative pressure, and start to suck sputum. The sputum passes through the second tube. One end of the second tube is cut off, and the second tube can be directly used as a device for collecting sputum for inspection. The existence of the one-way valve allows medical personnel to squeeze the body of the second tube, and the sputum is squeezed out.

Such a structure is low in cost, easy to use, and convenient to submit for inspection, and is worthy of large-scale promotion and use.

Example 2

As shown in Figure 2, the difference between this embodiment and Embodiment 1 is that it also includes a fourth pipe 6, and the fourth pipe is also arranged between the first pipe and the third pipe, and the fourth pipe is connected to the first pipe. The tubes are connected and integrally formed, the fourth tube is connected to the third tube and the second tube through the medical three-way valve, and the third tube and the second tube are also connected through the medical three-way valve.

Since the structure of the medical three-way valve 7 is a conventional prior art, it will not be described in detail in this embodiment.

Because when sucking sputum, only some saliva may be sucked out at the beginning, so at the beginning, adjust the three-way valve so that the third tube and the fourth tube are connected, and the third tube and the second tube are closed. When the sputum starts to be sucked out, since the sputum needs to be collected and submitted for inspection, the medical three-way valve is adjusted again at this time, so that the third tube and the second tube are connected, the third tube and the fourth tube are closed, and the sputum can be is collected in the second tube.

Example 3

As shown in FIG. 3 , the difference between this embodiment and Embodiment 1 is that the one-way valve is a bowl-shaped film structure, and the concave parts of the one-way valve of the bowl-shaped film structure are all facing the negative pressure suction device. Two points on the bowl wall of the bowl-shaped one-way flap are fixedly connected with the second tube, and the one-way flap ruler can completely cover the second tube. When the negative pressure suction device is turned on, the pressure extrudes the one-way valve to make the bowl walls close together. At this time, a gap appears between the bowl wall of the bowl-shaped one-way valve and the wall of the second tube, and sputum passes through. And because the one-way valve has a bowl-shaped structure, the sputum flows back to give pressure to the one-way valve, but because the bowl wall of the one-way valve is always in close contact with the second tube wall without leaving a gap, the refluxed sputum Cannot pass through one-way flap.

According to the above-mentioned embodiments, the present invention can be well realized. It is worth noting that, based on the premise of the above-mentioned structural design, in order to solve the same technical problem, even if some insubstantial changes or polishes are made on the present invention, the essence of the adopted technical solution is still the same as the present invention. Therefore, it should also be within the protection scope of the present invention.
