Detailed Description
The invention will be further described with reference to the following drawings and specific embodiments:
example (b):
referring to fig. 1 and 3, the present embodiment provides a gastric tube negative pressure drainage device, which includes a compression type negative pressure bottle 1; a liquid inlet 2 and a liquid outlet 3 are arranged on the negative pressure bottle 1; the stomach tube 4 is communicated with the negative pressure bottle 1 through the liquid inlet 2; the pressure spring 5 is arranged inside the negative pressure bottle 1; two ends of the pressure spring 5 are respectively connected with the upper top surface and the lower top surface in the negative pressure bottle 1; the liquid inlet 2 and the liquid outlet 3 are respectively arranged at the bottle top and the bottle bottom of the negative pressure bottle 1; a functional bottom plate 6 is detachably arranged at the bottom of the negative pressure bottle 1, and a pressure pump 7 is arranged on the functional bottom plate 6; the input end and the output end of the pressure pump 7 are respectively communicated with the liquid outlet 3 of the negative pressure bottle 1 and the metering bottle 8; and a valve is arranged at the liquid outlet 3 of the negative pressure bottle 1. In this example, a vacuum pump of KVP04 model manufactured by Kamoer corporation was used as the pressure pump; the pressure pump is connected with an external power supply, and the valve on the liquid outlet 3 is not drawn in the figure.
The bottom of the negative pressure bottle 1 is provided with a boss 11; a counter bore 61 is arranged at the upper top part of the functional bottom plate 6; the negative pressure bottle 1 is detachably mounted on the functional base plate 6 through the matching of the boss 11 and the counter bore 61. The positioning and assembling accuracy is guaranteed by arranging the boss 11 and the counter bore 61, so that the compression operation of the pressure spring 5 in the negative pressure bottle 1 is facilitated.
A spring clamp 63 is movably arranged on the functional bottom plate 6 along the radial direction; the operating end of the spring clip 63 is arranged on the outer side wall of the functional bottom plate 6, and the working end is arranged on the inner wall of the counter bore 61. In order to prevent the negative pressure bottle 1 from overturning from the functional bottom plate 6 when drainage and subsequent emptying operations are carried out, a pressing type spring clamp 63 is installed on the functional bottom plate 6, and the working end of the spring clamp 63 clamps the negative pressure bottle to prevent the negative pressure bottle from shaking.
A weight 62 is mounted on the bottom of the functional bottom plate 6. The purpose of the counterweight block 62 is to prevent the negative pressure bottle 1 from driving the functional bottom plate 62 to overturn due to turning around or the like during the patient lying in bed.
Referring to fig. 2, an internal thread is formed on the liquid inlet 2 of the negative pressure bottle 1; the stomach tube 4 is detachably arranged on the liquid inlet 2 through threaded connection; a sealing shaft sleeve 21 is also arranged at the joint of the liquid inlet 2 and the gastric tube 4.
