Description

Technical Field

[0001] This utility model relates to the field of blood pressure monitor technology, and in particular to a dual-pump column blood pressure monitor. Background Technology

[0002] The dual-pump column sphygmomanometer is based on the principle of hydrostatic balance. A communicating vessel connects the mercury reservoir to the indicator tube. When the surface of the mercury in the reservoir is pressurized, the mercury in the indicator tube rises to indicate the pressure value.

[0003] In existing technologies, dual-pump blood pressure timers are used. First, the upper arm is wrapped with a cuff and pressure is applied to compress the brachial artery. Then, the pressure is reduced. As the external pressure decreases, a friction and impact sound that is synchronized with the pulse can be heard from the stethoscope placed in the cuff after the blood flow reopens the blood vessel. The systolic and diastolic blood pressure are read by the pressure gauge, thus achieving the measurement purpose.

[0004] The above-mentioned and existing technologies have the following drawbacks: When operating a dual-pump blood pressure monitor, it needs to be placed vertically. At this time, the center of gravity of the dual-pump blood pressure monitor is relatively high. When medical staff operate it, the dual-pump blood pressure monitor is prone to shaking or even tipping over due to pulling, which may lead to inaccurate measurement results.

[0005] Therefore, a dual-pump column blood pressure monitor is proposed. Utility Model Content

[0006] The purpose of this invention is to address the drawback of dual-pump blood pressure monitors being prone to shaking or even tipping over when operated by medical personnel, and to propose a dual-pump blood pressure monitor.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a dual-pump column blood pressure monitor, comprising a storage box, a dual-column blood pressure monitor rotatably connected to the inner wall of the storage box, two mercury tubes fixedly connected inside the dual-column blood pressure monitor, an air delivery tube fixedly connected to the side wall of the dual-column blood pressure monitor, a strap fixedly connected to one end of the air delivery tube, a connecting tube fixedly connected to the surface of the strap, the connecting tube communicating with the air delivery tube, a balloon fixedly connected to one end of the connecting tube, a U-shaped plate fixedly fitted to the outer wall of the storage box, a support frame rotatably connected inside the U-shaped plate, an adjusting plate slidably connected to the inner wall of the support frame, and a support leg fixedly fitted to the surface of the adjusting plate.

[0008] The effect achieved by the above components is as follows: by setting up components such as support frame, adjustment plate and support legs, when using a dual-column blood pressure monitor, the support legs can increase the contact area between the storage box and the table, thereby improving the stability of the storage box and preventing the dual-column blood pressure monitor from shaking or even tipping over due to pulling.

[0009] Preferably, a rod slides through the U-shaped plate, and the surface of the support frame has a hole that matches the rod.

[0010] The effect achieved by the above components is that after the plug is inserted into the socket, the plug restricts the position of the support frame.

[0011] Preferably, a circular plate is fixedly mounted on the upper end of the insertion rod, and a spring is sleeved on the outer circumference of the insertion rod, with the two ends of the spring being fixedly connected to the circular plate and the U-shaped plate, respectively.

[0012] The effect achieved by the above components is that when the spring contracts, the circular plate will slide downward with the help of the spring's tension, and the sliding of the circular plate will cause the insertion rod to be inserted into the insertion hole.

[0013] Preferably, a collar is fixedly fitted on the lower surface of the circular plate, the spring is located inside the collar, and the collar abuts against the surface of the U-shaped plate.

[0014] The effect achieved by the above components is that the collar will shield the spring, protect the spring, and extend the service life of the spring.

[0015] Preferably, a retaining ring is fixedly fitted onto the outer circumferential surface of the insertion rod.

[0016] The effect achieved by the above components is that the sliding of the insertion rod will cause the retaining ring to slide. When the upper surface of the retaining ring contacts the U-shaped plate, the retaining ring can prevent the insertion rod from sliding out of the U-shaped plate, which would make subsequent operations inconvenient.

[0017] Preferably, the side wall of the support frame is threaded with bolts, which pass through the support frame and abut against the surface of the adjusting plate.

[0018] The effect achieved by the above components is that when the bolt is rotated and pressed against the surface of the adjusting plate, the bolt restricts the position of the adjusting plate, thereby restricting the position of the outrigger.

[0019] Preferably, the support frame is fixedly fitted with an L-shaped plate relative to the position of the bolt.

[0020] The effect achieved by the above components is that the L-shaped plate limits the movement distance of the bolts and prevents the bolts from coming out of the support frame.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting up components such as a support frame, an adjustment plate, and support legs, the support legs can increase the contact area between the storage box and the table when using a dual-column blood pressure monitor, thereby improving the stability of the storage box and preventing the dual-column blood pressure monitor from shaking or even tipping over due to pulling.

[0028] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0030] like Figures 1-4 As shown, this utility model provides a dual-pump column blood pressure monitor, including a storage box 1. A dual-column blood pressure monitor 2 is rotatably connected to the inner wall of the storage box 1. Two mercury column tubes 3 are fixedly connected inside the dual-column blood pressure monitor 2. An air delivery tube 4 is fixedly connected to the side wall of the dual-column blood pressure monitor 2. A strap 5 is fixedly connected to one end of the air delivery tube 4. A connecting tube 6 is fixedly connected to the surface of the strap 5. The connecting tube 6 is connected to the air delivery tube 4. A balloon 7 is fixedly connected to one end of the connecting tube 6. A U-shaped plate 8 is fixedly mounted on the outer wall of the storage box 1. A support frame 9 is rotatably connected inside the U-shaped plate 8. An adjusting plate 10 is slidably connected to the inner wall of the support frame 9. A support leg 11 is fixedly mounted on the surface of the adjusting plate 10.

[0031] A rod 12 slides through the U-shaped plate 8. A socket 13, matching the rod 12, is provided on the surface of the support frame 9. After the rod 12 is inserted into the socket 13, it restricts the position of the support frame 9. A circular plate 14 is fixedly mounted on the upper end of the rod 12. A spring 15 is fitted around the outer circumference of the rod 12. Both ends of the spring 15 are fixedly connected to the circular plate 14 and the U-shaped plate 8, respectively. When the spring 15 contracts, the circular plate 14 slides downwards under the pull of the spring 15. This sliding motion causes the rod 12 to insert into the socket 13. Inside the circular plate 14, a collar 16 is fixedly mounted on the lower surface. The spring 15 is located inside the collar 16. The collar 16 abuts against the surface of the U-shaped plate 8. The collar 16 will cover the spring 15, protect the spring 15, and extend the service life of the spring 15. A retaining ring 17 is fixedly mounted on the outer circumferential surface of the insertion rod 12. When the insertion rod 12 slides, it will drive the retaining ring 17 to slide. When the upper surface of the retaining ring 17 contacts the U-shaped plate 8, the retaining ring 17 can prevent the insertion rod 12 from sliding out of the U-shaped plate 8, which would make subsequent operations inconvenient.

[0032] Bolts 18 are threaded onto the side wall of the support frame 9. Bolts 18 pass through the support frame 9 and abut against the surface of the adjusting plate 10. When the bolts 18 are rotated and abut against the surface of the adjusting plate 10, the bolts 18 limit the position of the adjusting plate 10, thereby limiting the position of the support leg 11. An L-shaped plate 19 is fixedly mounted on the support frame 9 relative to the position of the bolts 18. The L-shaped plate 19 limits the movement distance of the bolts 18 and prevents the bolts 18 from coming out of the support frame 9.

[0033] The overall working principle is as follows: When the dual-column blood pressure monitor 2 needs to be used, first pull the collar 16 upwards. The collar 16 will drive the circular plate 14 to move. The circular plate 14 will pull the insertion rod 12 to slide and stretch the spring 15. The sliding of the insertion rod 12 will drive the retaining ring 17 to slide. When the upper surface of the retaining ring 17 contacts the U-shaped plate 8, the retaining ring 17 can prevent the insertion rod 12 from sliding out of the U-shaped plate 8, which would make subsequent operations inconvenient. Then, rotate the support frame 9. When the insertion hole 13 is aligned with the insertion rod 12, release the collar 16. At this time, the spring 15 will contract, and the circular plate 14 will slide downwards with the pull of the spring 15. The sliding of the circular plate 14 will cause the insertion rod 12 to be inserted into the insertion hole 13. The insertion rod 12 achieves the function of restricting the position of the support frame 9. At the same time, the collar 16 will cover the spring 15, protecting the spring 15 and extending its service life. When the support leg 11 is supported on the table, the support leg 11 can increase the contact area between the storage box 1 and the table, thereby To improve the stability of the storage box 1 and prevent the dual-column blood pressure monitor 2 from shaking or even tipping over due to traction, the dual-column blood pressure monitor 2 is then rotated out of the storage box 1 and placed in an upright position. The strap 5 is then tied to the patient's brachial artery, and the balloon 7 is pressed to apply pressure, followed by decompression. At the same time, the mercury column tube 3 is observed and tested with a stethoscope. When the position of the outrigger 11 needs to be adjusted, the bolt 18 is rotated. The bolt 18 will move due to the thread and disengage from the adjusting plate 10. At this time, the L-shaped plate 19 limits the movement distance of the bolt 18 and prevents the bolt 18 from coming out of the support frame 9. Then, the adjusting plate 10 is slid along the inner wall of the support frame 9. The sliding of the adjusting plate 10 will drive the outrigger 11 to move, thereby adjusting the position of the outrigger 11 as needed. After adjustment, the bolt 18 is rotated in the opposite direction. When the bolt 18 is against the surface of the adjusting plate 10, the bolt 18 limits the position of the adjusting plate 10, thereby limiting the position of the outrigger 11.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
