EXAMPLE III
The difference from the first embodiment is that, as shown in fig. 5, a plurality of grooves are formed on the bottom wall of the cavity 20, the sponge 17 with the volatile disinfectant adsorbed therein is placed in the grooves, the volatile disinfectant can be sterilized with alcohol, the mounting seat 19 is provided with an air outlet 12 communicated with the cavity 20, and the diameter of the air outlet 12 is smaller than that of the connecting pipe 8.
In the drainage process, the infrared transmitter 13 emits infrared light to detect whether the drainage tube 5 is extruded, the sponge 17 in the groove in the cavity 20 can volatilize under the action of the infrared light emitted by the infrared transmitter 13, meanwhile, when air in the air bag protecting sleeve 6 enters the cavity 20, volatilization of volatile disinfectant can be accelerated, and air with a disinfection function is promoted to overflow from the air outlet 12, because the floating ball 9 blocks the port of the connecting tube 8 when the drainage tube 5 is not extruded, the air in the air bag protecting sleeve 6 can not always overflow and disperse towards the mounting seat 19, the air in the air bag protecting sleeve 6 can not overflow and disperse completely before being extruded, the protection function of the air bag protecting sleeve 6 is ensured, the surrounding environment of drainage is disinfected, the diameter of the air outlet 12 is small, air cannot be discharged too much, and air in the air bag protecting sleeve 6 can not overflow rapidly and can not play a protection role, and can increase the disinfection times when the air bag protective sleeve 6 is extruded daily.
Example four
The difference with the second embodiment is that the drainage tube device further comprises a camera module, the camera module can use an existing high-definition camera, a view port of the camera module is aligned to a fluctuation section when the drainage tube 5 drains liquid, the camera module is used for collecting image information on the fluctuation section when the drainage tube 5 drains body fluid, the control module obtains the image information from the same area of the camera module at equal intervals, the control module adopts an internal clock for timing, and the control module obtains the contrast color of the body fluid in the drainage tube 5 for storage at regular time; the control module identifies the drainage color of the body fluid from the image information at equal intervals and matches the drainage color with the stored contrast color, for example, the interval can be set to two minutes, the color matching can be carried out by using the existing software, when the matching is successful, namely the identified drainage color is the same as the contrast color, the control module intercepts the graphic strip of the drainage color and adds a sequence number for storage; the control module carries out coincidence comparison on the adjacent figure strips with the sequence numbers, namely whether the lengths of the adjacent figure strips with the sequence numbers coincide or not is compared, and when the adjacent figure strips with the sequence numbers coincide, the control module controls the alarm module to alarm by a third preset sound, namely, the alarm is carried out when the body fluid in the drainage tube 5 does not fluctuate; when the extrusion signal is received and the adjacent image strips in the sequence number cannot be superposed, namely the drainage tube 5 is extruded and the lengths of the adjacent image strips in the sequence number are unequal, the control module controls the inflator pump to supplement inflation air into the air bag protective sleeve 6.
By shooting the image information of the fluctuation section on the drainage tube 5 and then identifying and comparing the colors from the image information for storage, the color of the body fluid to be drained can be obtained in time when the color of the body fluid to be drained changes, so that the accuracy of subsequent judgment of the fluctuation of the body fluid in the drainage tube 5 is improved; the figure strips for draining the body fluid are intercepted and numbered, the lengths of the figure strips with adjacent sequence numbers are compared to distinguish whether the body fluid in the drainage tube 5 fluctuates or not, and an alarm prompt is given when the body fluid in the drainage tube 5 does not fluctuate so as to enable medical staff to send problems in the drainage process in time; after the drainage tube 5 is extruded, the air bag protective sleeve 6 is triggered to be supplemented with air by the misalignment of the graphic strips, namely the normal fluctuation of the liquid in the drainage tube 5, so that the air in the air bag protective sleeve 6 can be ensured to be provided with air in the body fluid drainage process, and the drainage tube 5 can be provided with enough air to push the floating ball 9 to trigger alarm when being extruded.
The foregoing is merely an example of the present invention and common general knowledge of known specific structures and features of the embodiments is not described herein in any greater detail. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent. The scope of the claims of the present application shall be determined by the contents of the claims, and the description of the embodiments and the like in the specification shall be used to explain the contents of the claims.
