DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] An arterial pressure bag continuous pressurization capacity alarm device, such as Figure 1, including a pressurized bag 1, which is respectively connected to a pressure monitoring device and an inflation device through a first air pipe 2 and a second air pipe 3, the pressure monitoring device includes a sleeve barrel 4 communicated with the first air pipe 2, and a column 5 is slidably connected to the sleeve barrel 4 in the length direction of the sleeve barrel 4 through a moving part, the column 5 is coaxial with the sleeve barrel 4, and the bottom end of the column 5 passes through the bottom of the sleeve barrel 4 and extends to the outside of the sleeve barrel 4, and a high-pressure indication area 6, a transition area 7 and a low-pressure indication area 8 are provided on the side wall of the column 5, the high-pressure indication area 6, the transition area 7 and the low-pressure indication area 8 are all located outside the sleeve barrel 4, and the high-pressure indication area 6, the transition area 7 and the low-pressure indication area 8 are arranged in sequence from top to bottom, and a first alarm component is provided on the sleeve barrel 4. When the pressure of the pressurized bag 1 decreases, the moving part pushes the column 5 to move upward until the transition area 7 enters the sleeve barrel 4, and the first alarm component is used to sound an alarm.

[0023] like Figure 1 , the pressure of the pressurized bag 1 causes the liquid in the bagged liquid 19 to enter the human body from the infusion tube 20. As time goes by, when the pressure of the pressurized bag 1 decreases, the moving part automatically pushes the column 5 to move upward, so that the column 5 gradually enters the barrel 4. When the high-pressure indication area 6 on the column 5 completely enters the barrel 4 and the transition area 7 begins to enter the barrel 4, the first alarm part starts to sound an alarm. At this time, the sounding alarm of the first alarm part can remind medical staff that the pressurized bag 1 needs to be pressurized. Medical staff do not need to frequently observe the pressure monitoring device to understand the pressure of the arterial pressurization bag 1, which reduces the work intensity of medical staff. The pressure indicated by the high-pressure indication area 6 is V2, the pressure indicated by the transition area 7 is V1, and the pressure indicated by the low-pressure indication area 8 is V. V2 is greater than V1, and both V1 and V2 are greater than the maximum value of human blood pressure. V is equal to or less than the human blood pressure. It is simple and convenient to use.

[0024] like Figure 2 and Figure 3 The moving part includes a disc 9 and a sealing ring 10 coaxially arranged on the disc 9. The disc 9 is coaxially located in the barrel 4, and the sealing ring 10 on the disc 9 contacts the inner wall of the barrel 4. A compression spring 12 is provided between the disc 9 and the bottom of the barrel 4, and the column 5 is located on the inner side of the compression spring 12. The purpose of this arrangement is that when the bottom end of the column 5 is located outside the barrel 4, the compression spring 12 is in a compressed state. When the pressure of the pressurized bag 1 is reduced, the compression spring 12 will automatically push the disc 9 to move upward. At this time, the disc 9 will drive the column 5 to gradually enter the barrel 4. When the pressurized bag 1 is pressurized, the disc 9 will move downward, so that the column 5 gradually moves out of the barrel 4. It is simple and convenient to use.

[0025] like Figure 1The alarm component includes a bottom plate 13 horizontally arranged at the bottom end of the column 5 and a top plate 14 arranged below one side of the outer wall of the barrel 4. The top plate 14 is provided with a distance detector 15 for detecting the distance between the top plate 14 and the bottom plate 13. The top of the top plate 14 is provided with a first buzzer 16. The distance detector 15 controls the operation of the first buzzer 16.

[0026] like Figure 1 When the pressure of the pressurized bag 1 decreases, the disc 9 drives the column 5 and the column 5 gradually enters the barrel 4, and the bottom plate 13 moves upward with the column 5. When the high-pressure indication area 6 on the column 5 completely enters the barrel 4 and the transition area 7 begins to enter the barrel 4, the distance between the top plate 14 and the bottom plate 13 is H. At this time, the distance detector 15 detects the distance between the top plate 14 and the bottom plate 13. When the distance between the top plate 14 and the bottom plate 13 is equal to or less than H, the distance detector 15 controls the first buzzer 16 to start working. At this time, the first The buzzer 16 can sound an alarm to remind medical staff that the pressurization bag 1 needs to be pressurized. When the pressurization bag 1 is pressurized by the inflation device, the disc 9 and the column 5 move downward, and the distance between the top plate 14 and the bottom plate 13 is greater than H, the distance detector 15 controls the first buzzer 16 to stop working until the inflation device pressurizes the pressurization bag 1 so that the high-pressure indicating area 6 moves out of the sleeve barrel 4. Medical staff do not need to frequently observe the pressure monitoring device to understand the pressure of the arterial pressurization bag 1, which reduces the workload of medical staff and is simple and convenient to use.

[0027] like Figure 2 and Figure 3 A connecting groove 17 is provided at the top of the top plate 14, and a sliding column 18 is vertically provided at the top of the bottom plate 13. The top of the sliding column 18 vertically passes through the connecting groove 17, and the groove wall of the connecting groove 17 contacts the sliding column 18. The purpose of this arrangement is that the bottom plate 13 can be reduced by the cooperation between the sliding column 18 on the bottom plate 13 and the connecting groove 17 on the top plate 14 due to external force, which leads to the misalignment of the bottom plate 13 and the top plate 14, thereby causing the distance detector 15 to be unable to detect the distance between the top plate 14 and the bottom plate 13. It is simple and convenient to use.

[0028] like Figure 1A bagged liquid 19 is placed in the middle of the double-layer airbag of the pressurized bag 1, and an infusion tube 20 is connected to the bagged liquid 19. The infusion tube 20 includes a transparent first hose 21, a second hose 22 and a liquid storage barrel 23. The first hose 21 is connected to the bagged liquid 19, and the second hose 22 is located below the first hose 21. The first hose 21 and the second hose 22 are connected through the liquid storage barrel 23. A second alarm is provided on the liquid storage barrel 23. When the first hose 21 stops dripping the liquid in the bagged liquid 19 into the liquid storage barrel 23, the second alarm is used to sound an alarm. The purpose of this setting is to 1, so that the liquid in the bagged liquid 19 flows out from the second hose 22 through the first hose 21 and the liquid storage barrel 23 in sequence. At this time, an appropriate amount of liquid is stored in the liquid storage barrel 23. When the liquid in the bagged liquid 19 is exhausted and the first hose 21 stops dripping the liquid into the liquid storage barrel 23, the liquid in the liquid storage barrel 23 will flow out from the second hose 22. At this time, because the first hose 21 stops dripping the liquid into the liquid storage barrel 23, the liquid level in the liquid storage barrel 23 will gradually decrease, and the second alarm component starts to sound an alarm. At this time, the second alarm component sounds an alarm to remind medical staff that the bagged liquid 19 needs to be replaced; When the first alarm works and sounds an alarm but the second alarm does not work, it reminds the medical staff that the pressurizing bag 1 needs to be pressurized; When the first alarm element is not working and the second alarm element is working to sound an alarm, it reminds the medical staff that the bagged liquid needs to be replaced 19; When both the first alarm and the second alarm are working and sounding an alarm, it is a danger alarm, reminding medical staff that urgent action is needed; Through the cooperation of the first alarm component and the second alarm component, medical personnel can understand whether the pressurized bag 1 needs to be pressurized or the bagged liquid 19 needs to be replaced, thereby reducing the need for medical personnel to frequently observe the remaining liquid in the bagged liquid 19, and the use is simple and convenient.

[0029] like Figure 4 and Figure 5 The second alarm component includes an inverted U-shaped bracket 24 arranged at the top end of the liquid storage barrel 23 and a rotating shaft 25 rotatably connected between the opposite sides of the bracket 24, and a plurality of blades 26 are evenly distributed on the rotating shaft 25 along the circumference of the rotating shaft 25. The end of the first hose 21 connected to the liquid storage barrel 23 is misaligned with the rotating shaft 25. At this time, the blade 26 located on one side of the rotating shaft 25 is located below the first hose 21. An inverted U-shaped mounting plate 27 is provided at the top end outside the liquid storage barrel 23, and an infrared transmitter 28 and an infrared receiver 29 are respectively provided on the opposite sides of the mounting plate 27. The infrared transmitter 28 and the infrared receiver 29 are respectively located on both sides of the liquid storage barrel 23. One of the blades 26 on the rotating shaft 25 is located between the infrared transmitter 28 and the infrared receiver 29. A second buzzer 30 is provided at the top end of the mounting plate 27, and the infrared receiver 29 controls the operation of the second buzzer 30.

[0030] like Figure 4 and Figure 5 When the liquid in the bagged liquid 19 drips from the first hose 21 into the liquid storage barrel 23, the dripping liquid will drive the rotating shaft 25 to rotate through the blades 26 on the rotating shaft 25. At this time, the blades 26 rotate along the rotation axis of the rotating shaft 25. At this time, because one of the blades 26 on the rotating shaft 25 is located between the infrared transmitter 28 and the infrared receiver 29, when each blade 26 rotates along the rotation axis of the rotating shaft 25, the signal emitted by the infrared transmitter 28 can be intermittently blocked by each blade 26. At this time, the infrared receiver 29 receives the intermittent signal; When the liquid in the bagged liquid 19 runs out and the first hose 21 stops dripping the liquid into the liquid storage barrel 23, the rotating shaft 25 stops rotating. At this time, the intermittent blocking of the signal emitted by the infrared transmitter 28 by the blade 26 stops. At this time, the infrared receiver 29 does not receive the intermittent signal, and the infrared receiver 29 controls the second buzzer 30 to sound an alarm to remind medical staff that the bagged liquid 19 needs to be replaced. It is simple and convenient to use.

[0031] like Figure 1 The inflation device includes an inflation balloon 31 connected to the second air pipe 3. The purpose of this arrangement is to pressurize the pressurized bag 1 from the second air pipe 3 through the inflation balloon 31, which is simple and convenient to use.

[0032] The inflatable balloon 31 is an existing structure, and this application will not describe it in detail here.

[0033] like Figure 6 Alternatively, the inflation device includes an inflation pump 32 connected to the second air pipe 3. At this time, the distance detector 15 controls the inflation pump 32 to work, and the inflation pump 32 replaces the first buzzer 16. The purpose of this setting is that when the distance between the top plate 14 and the bottom plate 13 is equal to or less than H, the distance detector 15 controls the inflation pump 32 to start working and pressurize the pressurized bag 1 from the second air pipe 3. At this time, the sound of the inflation pump 32 working can be used as a sound alarm, which is simple and convenient to use.

[0034] like Figure 1 The high-pressure indication area 6, the transition area 7 and the low-pressure indication area 8 on the column 5 are marked with different colors. The purpose of this setting is to facilitate medical staff to understand the pressure applied by the pressurization bag 1 by marking the high-pressure indication area 6, the transition area 7 and the low-pressure indication area 8 with different colors, and the use is simple and convenient.

[0035] like Figure 4The liquid storage barrel 23 is made of transparent plastic material. A retaining ring 33 is provided at the bottom end of the mounting plate 27. The retaining ring 33 is coaxial with the liquid storage barrel 23. The inner wall of the retaining ring 33 is fixedly connected to the outer wall of the liquid storage barrel 23. The purpose of this arrangement is that the retaining ring 33 fixedly connected to the outer wall of the liquid storage barrel 23 on the mounting plate 27 can protect the rotating shaft 25 and the blades 26 in the liquid storage barrel 23, thereby reducing the situation in which the liquid storage barrel 23 is squeezed by external force when the infusion tube 20 is used or placed, causing the inner wall of the liquid storage barrel 23 to contact and collide with the blades 26, causing damage to the blades 26 or the liquid storage barrel 23. The use is simple and convenient.

[0036] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
