Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and more specifically, to an auxiliary device for the examination of the left renal vein. Background Art

[0002] Nutcracker syndrome of the left renal vein, also known as left renal vein compression syndrome. This is a disease caused by the compression of the left renal vein during the reflux process, mainly occurring during the reflux of the blood in the left renal vein to the inferior vena cava, being squeezed by the angle formed by the abdominal aorta and the superior mesenteric artery or the gap between the abdominal aorta and the spine, resulting in an increase in the pressure of the left renal vein.

[0003] When performing an abdominal ultrasound examination on a patient to exclude the angle between the abdominal aorta and the superior mesenteric artery and check whether there is compression (nutcracker sign) of the left renal vein, the patient needs to be in the dorsal extension position for 15 - 20 minutes, and then observe whether the left renal vein is narrowed due to the dorsal extension position, effectively reducing the false negative of the left renal vein "nutcracker sign". The existing method usually overlaps the pillows on the examination bed on the patient's waist.

[0004] Using folded pillows for dorsal extension has poor fitting degree and poor dorsal extension effect. The folded pillows have different sizes and heights, resulting in different dorsal extension effects, which may increase the false negative rate of the left renal vein "nutcracker sign" and affect the ultrasonic diagnosis.

[0005] Based on the above problems, we provide an auxiliary device for the examination of the left renal vein.

[0006] The above information disclosed in this background art is only used to increase the understanding of the background art of the utility model. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Summary of the Utility Model

[0007] In order to solve the problems raised in the above background art, the utility model provides an auxiliary device for the examination of the left renal vein.

[0008] The auxiliary device for the examination of the left renal vein provided by the utility model adopts the following technical scheme:

[0009] An auxiliary device for the examination of the left renal vein includes an air cushion; an examination pad disposed on the top of the air cushion, and the shape of the examination pad is an arch conforming to the curve of the human spine; a timing mechanism disposed in the examination pad for calculating the time of the patient in the dorsal extension position.

[0010] Preferably, the timing mechanism includes an electronic timer and a pressure sensor, the electronic timer is assembled on the side of the inspection pad, the pressure sensor is arranged at the top center of the inspection pad, and the pressure sensor can control the opening of the electronic timer.

[0011] Preferably, a chamber is opened at the center of the top of the inspection pad, the pressure sensor is installed in the chamber, a partition is fixedly installed in the chamber, a contact rod is slidably inserted at the top of the partition, the bottom end of the contact rod corresponds to the position of the pressure sensor, a pressure block is fixedly connected to the top of the contact rod, two sliding rods are fixedly connected to the bottom of the pressure block, and the bottom ends of the two sliding rods are arranged below the partition, and a spring is passed through the middle of the sliding rod between the partition and the pressure block.

[0012] Preferably, the electronic timer is capable of voice reminder.

[0013] Preferably, the air cushion is inflatable, and an air nozzle is installed on the side of the air cushion.

[0014] Preferably, the inspection pad is adhered to the top surface of the air cushion by Velcro.

[0015] Preferably, an inflatable airbag is installed at a position on the top of the air cushion located on the side of the inspection pad, and the inflatable airbag is connected to an air pump.

[0016] Preferably, the inflatable airbag can assist in repositioning the patient's back after expansion.

[0017] In summary, the utility model includes the following beneficial technical effects:

[0018] The patient lies on the air cushion and puts his back against the examination pad for dorsal extension. When the back is in contact with the examination pad, it presses down the pressure block, causing the pressure block to move into the chamber. At this time, the contact rod squeezes the pressure sensor, which converts the pressure into an electrical signal and sends it to the electronic timer. The electronic timer performs timing work, thereby simulating the angle between the abdominal aorta and the superior mesenteric artery to be under pressure: for patients with a positive "Nutcracker sign", the left renal vein is compressed for 15-20 minutes, and there will be obvious narrowing between the abdominal aorta and the superior mesenteric artery, and the inner diameter on the left kidney side will be significantly expanded, thereby improving the detection rate of positive "Nutcracker sign" of the left renal vein by ultrasound diagnosis. Through this structural design, the dorsal extension position required for ultrasound examination of the left renal vein "Nutcracker sign" can be effectively simulated, the detection rate of the "Nutcracker" sign can be improved, and false negative test results can be reduced. It is ergonomic, and timing starts immediately when pressure is applied, which improves comfort and avoids secondary injuries.

[0028] Embodiment 1

[0029] The present embodiment of the present utility model discloses an auxiliary device for the examination of the left renal vein. Refer to Figures 1 to 4, An auxiliary inspection device for the left renal vein, comprising an air cushion 1; an inspection pad 2, arranged on the top of the air cushion 1, and the shape of the inspection pad 2 is an arch shape conforming to the human spinal curve; a timing mechanism, arranged inside the inspection pad 2, for calculating the time of the patient's dorsal extension position.

[0030] Specifically, the timing mechanism includes an electronic timer 3 and a pressure sensor 4. The electronic timer 3 is assembled on the side of the inspection pad 2, the pressure sensor 4 is arranged at the center of the top of the inspection pad 2, and the pressure sensor 4 can control the start of the electronic timer 3.

[0031] Specifically, a chamber 5 is opened at the center of the top of the inspection pad 2. The pressure sensor 4 is assembled inside the chamber 5. A partition 6 is fixedly assembled inside the chamber 5. A contact rod 7 is slidably inserted at the top of the partition 6. The bottom end of the contact rod 7 corresponds to the position of the pressure sensor 4. The top end of the contact rod 7 is fixedly connected with a pressing block 8. Two sliding rods 9 are fixedly connected to the bottom of the pressing block 8, and the bottom ends of the two sliding rods 9 are both arranged below the partition 6. A spring 10 is sleeved on the middle part of the sliding rod 9 between the partition 6 and the pressing block 8.

[0032] The patient lies on the air cushion 1 and presses the back against the inspection pad 2 for dorsal extension. When the back is attached to the inspection pad 2, it will press down the pressing block 8, causing the pressing block 8 to move into the chamber 5. At this time, the contact rod 7 will squeeze the pressure sensor 4. The pressure sensor 4 converts the pressure into an electrical signal and sends it to the electronic timer 3. The electronic timer 3 starts timing, so as to simulate the pressure on the angle between the abdominal aorta and the superior mesenteric artery: for patients with a positive "nutcracker syndrome", the left renal vein is compressed for 15 - 20 minutes, and there will be obvious stenosis between the abdominal aorta and the superior mesenteric artery, and the inner diameter of the left kidney will be significantly dilated, thus improving the detection rate of a positive "nutcracker syndrome" in the ultrasonic diagnosis of the left renal vein;

[0033] Secondly, since patients with a positive "nutcracker syndrome" of the left renal vein are not suitable for performing the dorsal extension position for too long to avoid aggravating the compression of the left renal vein, an electronic timer 3 is set up to accurately control the time of the dorsal extension position.

[0034] Compared with the current clinical routine method, this device can effectively simulate the dorsal extension position required for the ultrasonic examination of the left renal vein "nutcracker syndrome", improve the detection rate of the "nutcracker" syndrome, and reduce false negative examination results; and this device conforms to ergonomics, and the comfort level can be greatly improved. Timing starts immediately when pressed, effectively avoiding secondary injuries; at the same time, it can also be disinfected separately.

[0035] Specifically, the electronic timer 3 can give a voice reminder.

[0036] Specifically, the air cushion 1 is inflatable, and an air nozzle is assembled on the side of the air cushion 1, and the air cushion 1 can be inflated according to the patient's body shape.

[0037] Specifically, the inspection pad 2 is adhered to the top surface of the air cushion 1 by Velcro 11.
