Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field, specifically, relate to a inferior vena cava internal diameter monitor. BACKGROUND

[0002] In the emergency department, for trauma, septic shock, gastrointestinal bleeding and other critically ill patients, it is extremely important to determine whether there is hypovolemia or hypervolemia. If the hypovolemia is not accurately determined in time, it will lead to insufficient tissue perfusion and cause organ dysfunction and even failure. If the hypervolemia cannot be accurately determined, too much fluid will increase the burden on the heart and make the heart bear more pressure for blood circulation, which may cause heart failure and other serious complications. In addition, it is of great significance to continuously monitor the volume status of patients. Through continuous monitoring, the blood volume of patients can be understood in real time, and once abnormal conditions such as hypovolemia or hypervolemia occur, it can be found in time so that medical staff can take appropriate treatment measures, adjust the infusion amount, etc., to protect the life safety of patients and reduce the risk of complications, providing key basis and support for the treatment of critically ill patients.

[0003] In the prior art, the main method for determining the blood volume of patients is to perform central venous catheterization, that is, to insert a catheter into the central vein (usually large veins such as the superior and inferior vena cava). Then, by monitoring the central venous pressure (CVP), that is, the pressure value in the central vein, and comparing it with the blood pressure of the patient, it is determined whether the patient has hypovolemia or hypervolemia. If the central venous pressure is too low and the blood pressure is also abnormal, it may indicate that the patient has hypovolemia, and vice versa. However, this method has obvious technical defects. On the one hand, the central venous catheterization process is painful and takes a certain amount of time, and even patients with good blood vessel conditions may have difficulty puncturing. On the other hand, the central venous catheterization also increases the risk of infection for patients. UTILITY MODEL CONTENT

[0027] ​The monitor of the present application has significant advantages in actual use. After filling the coupling agent in the internal space of the bellows 300, the port away from the connecting plate 200 is covered in the position under the xiphoid of the patient, and is positioned on the body of the patient with the adhesive tape 100. By cooperating the B-ultrasound probe with the host 600 to carry out developing detection, the image information of the inferior vena cava of the patient can be obtained, the diameter monitoring of the inferior vena cava is realized, and is displayed on the display 700. By observing the diameter change of the inferior vena cava, it can be determined whether the patient is blood volume deficient. If there is a concave change, the blood volume is insufficient, and if it is in a continuous filling state, the blood volume is overloaded. Compared with the traditional central venous catheterization operation detection method, the monitor not only does not bring pain to the patient, but also avoids the risk of infection, and has strong practicability. In addition, by utilizing the bending deformation of the bellows 300 and the rotation adjustment of the B-ultrasound probe, the orientation change of the detection end of the B-ultrasound probe can be realized, so that the visual interval is larger, and the practicability of the monitor is further improved, which provides a more convenient and effective means for clinical judgment of the blood volume condition of the patient.

[0028] As a more preferred embodiment, the connecting plate 200 is provided with an adding hole communicating the internal and external spaces of the bellows 300, for filling the coupling agent into the internal space of the bellows 300.

[0029] The adding hole is detachably provided with a rubber plug 800.

[0030] In the above embodiment, the connecting plate 200 provided with the adding hole communicating the internal and external spaces of the bellows 300 has many advantages. First, the adding hole facilitates filling the coupling agent into the internal space of the bellows 300, making the operation more convenient and efficient. In actual use, the coupling agent can be added through the adding hole at any time as needed, ensuring good coupling effect, so as to ensure that the monitor can accurately obtain the image information of the inferior vena cava of the patient. Second, the detachable rubber plug 800 can close the adding hole when the coupling agent is not needed, preventing the coupling agent from leaking and external impurities from entering the internal space of the bellows 300, ensuring the cleanliness and stability of the internal space of the bellows 300. At the same time, the detachable design of the rubber plug 800 makes it easy to open the adding hole when the coupling agent is needed, which is convenient for operation.

[0031] As a more preferred embodiment, the handle end of the B-ultrasound probe 500 is provided with an indicator light 400.

[0032] In the above embodiment, the indicator light 400 can provide a state prompt during use, which facilitates the operator to quickly understand the working condition of the probe, and improves the operation efficiency and accuracy.

[0033] As a more preferred embodiment, the number of the adhesive tapes 100 is multiple, and they are arranged in a circumferential interval along the outer ring surface of the bellows 300.

[0034] In the above embodiment, the plurality of adhesive tapes 100 are circumferentially spaced apart along the outer circumferential surface of the bellows 300, which has multiple advantages. First, the plurality of adhesive tapes 100 can provide more stable fixation, ensuring the position of the bellows 300 on the patient's body stable and not displaced due to the patient's slight movements, thereby ensuring the accuracy of monitoring. Second, the circumferentially spaced adhesive tapes 100 can evenly distribute the fixation force, avoiding excessive local force on the patient's skin. Third, the plurality of adhesive tapes 100 increase the reliability of fixation, even if one of the adhesive tapes 100 loosens, the other adhesive tapes 100 can still play a certain fixing role.

[0035] Please refer to Figures 2-4 As a preferred embodiment, the outer circumferential surface of the detection end of the B-ultrasound probe 500 is circumferentially provided with a ring-shaped rotating member 1000, and the connecting plate 200 is provided with a ring-shaped groove adapted to the rotation of the ring-shaped rotating member 1000.

[0036] In the above embodiment, the cooperation of the ring-shaped rotating member 1000 and the ring-shaped groove can ensure the stability of the probe during rotation, avoiding the influence of image quality due to shaking.

[0037] As a preferred embodiment, the connecting plate 200 is threadedly connected with a locking bolt 900 for positioning after the rotation of the ring-shaped rotating member 1000.

[0038] In the above embodiment, the threadedly connecting the connecting plate 200 with the locking bolt 900 has multiple advantages. First, after the ring-shaped rotating member 1000 adjusts the detection angle of the B-ultrasound probe 500, the locking bolt 900 can position the ring-shaped rotating member 1000, ensuring that the probe maintains a stable angle during monitoring, avoiding the influence of image quality and monitoring accuracy due to accidental shaking. Second, the locking bolt 900 is simple and convenient to operate, which can quickly realize the fixation and adjustment of the probe angle, improving the operation efficiency.
