Description

TECHNICAL FIELD

[0001] The utility model relates to hospital supplies field especially, relate to a medical tube air bag inflation water filler. BACKGROUND

[0002] Many medical tubes in hospitals have air bags, such as tracheal tube, urinary tube, and gastric tube. For details, see the patents disclosed in the patent application numbers 201821336151.4, 201420332312.8, 200920240483.7, etc. for tracheal tube; the patent application numbers 201922148115.6, 200420098700.0, 201220077917.8, etc. for urinary tube; and the patent application numbers 202211428764.1, 202120073417.6, etc. for gastric tube.

[0003] The air bag on the above medical tube is often inflated after being placed in the human body, and is clamped in a specific position of the human body to prevent the medical tube from falling out. The air bag may also be inflated with water to achieve the same effect of being clamped in a specific position of the human body to prevent the medical tube from falling out. For example, the air bag of the tracheal tube is often inflated to prevent the air bag from being too hard and causing obvious compression to the tracheal mucosa. The urinary tube may be inflated with water to prevent compression and achieve better positioning effect.

[0004] Currently, there is no special tool for inflating or filling water in the air bag of the medical tube. Instead, a syringe is used. After the syringe sucks in air or water, it is connected to the inflation interface of the medical tube for inflation or water filling. In addition to the syringe, normal saline is also prepared for each water filling. After the syringe sucks in the normal saline, it is injected into the air bag. One extraction of normal saline can only complete the water filling of the air bag of one medical tube. The syringe is discarded after use, which is not very convenient. In addition, the inflation degree of the air bag has requirements. The water injection amount of the air bag is generally required to be strictly controlled during water filling; and the air pressure of the air bag is required to be controlled during inflation, such as the air pressure of the air bag of the tracheal tube being required to be 25-30 cmH2O. Since the syringe has a scale, the water filling amount of the syringe is easy to control. Although the syringe can control the inflation amount through the scale, it is difficult to achieve the purpose of strictly controlling the air pressure of the air bag by relying on the volume of the inflation. It is often necessary to measure the pressure after inflation and adjust the inflation and deflation, which is also not very convenient. SUMMARY

[0026] The utility model discloses a water storage bottle 2 is filled with physiological saline before use. If needing to inflate, the first three -way valve 4 is adjusted to make the second pipeline 7 and the fifth pipeline 10 communicate, and the second three -way valve 5 is adjusted to control the fifth pipeline 10 and the fourth pipeline 9 communicate. Then the manual pump 3 is operated by holding the handle 1-2, and air enters the manual pump 3 through the second pipeline 7, the first three -way valve 4, the fifth pipeline 10, the second three -way valve 5 and the fourth pipeline 9.

The marks for the first three-way valve 4 can be "water" and "gas", and when the knob of the first three-way valve 4 is against "water", the first pipeline 6 is communicated with the fifth pipeline 10 to fill water; and when the knob of the first three-way valve 4 is against "gas", the second pipeline 7 is communicated with the fifth pipeline 10 to fill gas. The marks for the second three-way valve 5 can be "suction" and "output", and when the knob of the second three-way valve 5 is against "suction", the fifth pipeline 10 is communicated with the fourth pipeline 9; and when the knob of the second three-way valve 5 is against "output", the third pipeline 8 is communicated with the fourth pipeline 9.

[0030] The air bag is generally required to control the air pressure of the air bag, for example, the air pressure of the air bag for tracheal intubation is required to be 25-30 cmH2O. In order to conveniently control the air pressure, the medical tube air bag inflator is preferably provided with a pressure gauge 12, which is installed on the shell 1 and communicated with the third pipeline 8.

[0031] The pressure gauge 12 is further provided, which is communicated with the third pipeline 8, and when the air bag is inflated, the air bag, the connecting joint 11 and the third pipeline 8 are communicated, and the pressure gauge 12 measures the air pressure in the third pipeline 8, which also measures the air pressure in the air bag, so that the air pressure in the air bag can be known in real time when the air bag is inflated, and thus the inflation can be stopped when the air pressure in the air bag reaches the required value. In this way, the air bag can be conveniently inflated, and the air pressure in the air bag can be accurately ensured. The pressure gauge 12 can be a product of the prior art, and the range thereof should cover 25-30 cmH2O.

[0033] The specific structure of the hand pump 3 is shown in Figure 3 As shown, the hand pump 3 includes a pump shell 3-1, a piston 3-2, a front piston rod 3-3 and a rear piston rod 3-4, the pump shell 3-1 is arranged in the front-rear direction, the piston 3-2 is located in the pump shell 3-1 and cooperates with the pump shell 3-1, a closed pump cavity 3-5 is formed between the front end of the pump shell 3-1 and the piston 3-2, the front piston rod 3-3 and the rear piston rod 3-4 are respectively located in front of and behind the piston 3-2 and are connected with the piston 3-2, and the front piston rod 3-3 and the rear piston rod 3-4 respectively extend to expose the handle 1-2.

[0034] As shown in Figure 3 The hand handle 1-2 is held, the index finger is pressed backward to the front piston rod 3-3, and the hand pump 3 sucks water or gas; the thumb is pressed forward to the front piston rod 3-3, and the hand pump 3 outputs water or gas; and the hand can be operated.

[0035] When the air bag is filled with water, the water filling amount of the air bag is generally required to be strictly controlled. In order to achieve this purpose, the position corresponding to the handle 1-2 and the manual pump 3 is preferably transparent, the pump shell 3-1 is transparent, and the pump shell 3-1 has a scale for indicating the water or air suction amount in the pump cavity 3-5. Specifically, the scale opposite to the front edge of the piston 3-2 corresponds to the volume of the pump cavity 3-5.

[0036] When the air bag is filled with water or gas, it will not be in contact with human tissues when the air bag is not broken. However, the possibility of air bag rupture cannot be ruled out, and the water and gas are clean. Therefore, the utility model preferably comprises two external communication devices 13, the external communication device 13 comprises a communication pipe 13-1 and a filter membrane 13-2 arranged in the communication pipe 13-1, the external communication device 13 is installed on the shell 1, one external communication device 13 is communicated with the water storage bottle 2, and the other external communication device 13 is communicated with the second pipeline 7. The filter membrane is filtered to ensure clean air and avoid air pollution in the water storage bottle 2. In addition, the external communication device 13 communicated with the water storage bottle 2 also makes the air pressure in the water storage bottle 2 be atmospheric pressure, so as to avoid the influence of air pressure on the water output in the water storage bottle 2. The filter membrane 13-2 is preferably a waterproof and breathable membrane, so as to prevent the water in the water storage bottle 2 from overflowing through the filter membrane 13-2. As shown in the figure, the inner hole of the communication pipe 13-1 is preferably a tapered hole with an outer diameter and an inner diameter. Figure 4
