Description

Technical Field

[0001] This utility model relates to the field of ultrasonic probe technology, and in particular to a medical ultrasonic probe fixing device. Background Technology

[0002] In clinical practice, rapid diagnosis of traumatic diseases of the thoracic, abdominal, and cardiac organs mainly relies on examination methods such as MRI, CT, and ultrasound to quickly detect traumatic diseases and the resulting pleural, abdominal, and pericardial effusions. Currently, bedside ultrasound is an important method for rapid disease diagnosis compared to MRI and CT. Unexpected bleeding after trauma and surgery is very common in clinical practice. According to incomplete statistics, the incidence of postoperative bleeding after abdominal surgery is about 0.5% to 3%, and the rate of rebleeding after thoracic surgery is 1.25% to 1.94%. Patients with rebleeding or delayed bleeding after surgery rely heavily on doctors and nurses to observe the patient's vital signs. Often, the possibility of postoperative rebleeding or delayed bleeding is only considered when the patient's life becomes unstable. In such cases, accurate clinical diagnosis often depends on bedside ultrasound assessment, which to some extent delays the patient's diagnosis and treatment.

[0003] Therefore, using ultrasound equipment to observe a patient's physical condition 24 hours a day can promptly detect changes in the patient's condition. This requires fixing the probe to the patient's body surface for extended periods of observation. However, existing methods of fixing the probe typically involve attaching it to the patient's body surface with medical tape. Since the probe needs to be coated with a coupling agent to improve imaging effects during use, this method cannot store the coupling agent for a long time. The probe needs to be removed periodically to apply the coupling agent. Therefore, a medical ultrasound probe fixing device that can store the coupling agent is proposed. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a medical ultrasound probe fixation device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A medical ultrasound probe fixation device includes a fixation member for fixing the probe. The probe is snapped into the inside of the fixation member by a second limiting component. A storage cavity for storing coupling agent is formed inside the fixation member between the probe and the skin. The fixation member has a discharge hole for discharging excess coupling agent on the side near the second limiting component.

[0006] In some embodiments, the second limiting component includes a limiting block fixed on the side of the probe away from the data cable, the inner frame surface of the fixing member is provided with a groove that cooperates with the limiting block, and the side of the fixing member away from the groove is provided with a placement groove for placing the data cable.

[0007] In some embodiments, a square guide rod is fixedly connected inside the fixing member, and a limit rod slides on one end of the square guide rod near the groove. The limit rod cooperates with the limit block to fix the probe.

[0008] In some embodiments, a pressure plate is rotatably connected to one side of the mounting slot of the fixing member, and a locking post is fixed thereon. The pressure plate fixes the data cable through the locking post.

[0009] In some embodiments, the fastener is provided with a sealing assembly for sealing the discharge hole on the side near the discharge hole. The sealing assembly includes a cover plate fixed to the side of the limiting rod near the edge by a connecting rod, and a rubber pad is fixedly connected to the cover plate on the side near the discharge hole.

[0010] In some embodiments, the fastener includes an inner frame that mates with the probe and an edge for attaching to the patient's skin.

[0011] Compared with the prior art, the present invention provides a medical ultrasound probe fixation device, which has the following beneficial effects.

[0012] 1. This utility model uses an adhesive layer to attach the fixing component to the patient's skin, and the fixing component and the second limiting component work together to fix the probe to the patient's skin, achieving the purpose of long-term monitoring. By setting a storage cavity, it is convenient to store coupling agent and avoid the probe from being repeatedly coated with coupling agent during long-term monitoring.

[0013] 2. This utility model, by setting a discharge hole, facilitates the discharge of excess coupling agent. By setting a closing component, when the probe is installed, the limiting block pushes the limiting rod backward, and at the same time drives the cover plate to disengage from the discharge hole, so as to open the discharge hole synchronously. The spring pushes the limiting rod to reset, and at the same time drives the cover plate to reset, thus sealing the discharge hole. This prevents the coupling agent from flowing out of the discharge hole during long-term monitoring, which would cause insufficient coupling agent in the storage cavity, create a cavity, and affect the probe detection.

[0014] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-6 A medical ultrasound probe fixing device includes a probe 2 and a fixing member 12 for fixing the probe 2 to the surface of a patient's skin. The probe 2 is a flat square shape, and a chip 201 is disposed on the largest side of the probe 2. The fixing member 12 includes an inner frame that cooperates with the probe 2 and an edge for being pasted onto the patient's skin. An adhesive layer and a protective film for the adhesive layer are provided on the contact surface between the edge and the skin. The probe 2 is snapped into the inside of the fixing member 12 by a second limiting component 15, and a storage cavity 13 for storing coupling agent is formed inside the fixing member 12 between the probe 2 and the skin. A discharge hole 14 is provided on the side of the fixing member 12 near the second limiting component 15, and the position of the discharge hole 14 corresponds to that of the storage cavity 13.

[0024] Understandably, by setting the probe 2 to a flat, square shape, it is easier to adhere to the patient's skin for a long time, reducing the impact of the probe 2 on the patient. By setting an adhesive layer, it is easier to attach the fixing member 12 to the patient's skin. By setting a storage cavity 13, it is easier to store coupling agent, avoiding the need for the probe 2 to be repeatedly coated with coupling agent during long-term monitoring. The fixing member 12 and the second limiting component 15 work together to fix the probe 2 to the patient's skin, achieving the purpose of long-term monitoring. By setting a discharge hole 14, it is easier to discharge excess coupling agent.

[0025] Specifically, the second limiting component 15 includes a limiting block 1501 fixed on the side of the probe 2 away from the data cable. A groove 1502 is provided on the inner frame surface of the fixing member 12. A square guide rod 1503 is fixedly connected inside the fixing member 12. A limiting rod 1504 slides on one end of the square guide rod 1503 near the groove 1502. A slope is provided on one end of the limiting rod 1504 near the groove 1502. A limiting groove is formed on the side of the limiting block 1501 near the limiting rod 1504. A limiting groove is sleeved on the surface of the square guide rod 1503 for driving the limiting rod 1504. The spring inserted into the limiting groove on the surface of the limiting block 1501 by the positioning rod 1504 is provided on the side of the limiting rod 1504. The fixing member 12 has a placement groove 17 for placing the data cable on the side away from the groove 1502. The fixing member 12 is rotatably connected to the side with the placement groove 17 and is fixed with a locking post 19. The pressure plate 18 and the locking post 19 are respectively set on both sides of the placement groove 17. The surface of the pressure plate 18 has an arc-shaped groove for cooperating with the data cable and a locking groove for cooperating with the locking post 19. The locking groove and the locking post 19 are interference fit.

[0026] It is understandable that when the probe 2 is placed in the inner frame of the fixing member 12, the depth of the groove 1502 and the placement groove 17 is used to limit the height of the probe 2, thereby forming the storage cavity 13. At the same time, after the limiting block 1501 enters the groove 1502, the limiting rod 1504 is driven by the spring to insert into the surface of the limiting block 1501 to fix the probe 2. Through the cooperation of the pressure plate 18 and the locking post 19, the pressure plate 18 fixes one end of the data cable of the probe 2. By limiting and fixing both ends of the probe 2 respectively, the probe 2 is prevented from shaking in the fixing member 12, which would affect the monitoring effect. By moving the lever, the limiting rod 1504 is slid into the fixing member 12, so that the limiting rod 1504 is disengaged from the limiting block 1501, making it easy to take the probe 2 out of the fixing member 12.

[0027] Specifically, a sealing component 16 for sealing the discharge hole 14 is provided on the side of the fastener 12 near the discharge hole 14. The sealing component 16 includes a cover plate 1601 fixed to the side of the limiting rod 1504 near the edge via a connecting rod. A rubber pad 1602 is fixedly connected to the side of the cover plate 1601 near the discharge hole 14, and a baffle 1603 is fixedly connected to the side of the edge away from the adhesive layer. The cover plate 1601 and the rubber pad 1602 slide between the baffle 1603 and the inner frame.

[0028] It is understandable that when the limiting rod 1504 slides to the side of the limiting block 1501, the connecting rod drives the cover plate 1601 to slide between the baffle 1603 and the inner frame, which facilitates the sealing of the discharge hole 14. This prevents the coupling agent from flowing out of the discharge hole 14 during long-term monitoring, causing insufficient coupling agent in the storage cavity 13, creating a cavity, and affecting the detection of the probe 2.

[0029] In this invention, the fixing member 12 is attached to the patient's body surface, coupling agent is applied to the storage cavity 13 of the fixing member 12, and the probe 2 is placed inside the fixing member 12. Under the action of the second limiting component 15 and the clamping plate 501, the two ends of the probe 2 are respectively limited and fixed, thereby preventing the probe 2 from shaking inside the fixing member 12 and affecting the monitoring effect. At the same time, when the limiting block 1501 enters the groove 1502, the limiting block 1501 pushes the limiting rod 1504 into the fixing member 12. Simultaneously, it drives the cover plate 1601 and the rubber pad 1602 to disengage from the discharge hole 14, allowing excess coupling agent to flow out from the discharge hole 14. Then, the spring pushes the cover plate 1601 and the rubber pad 1602 to reset and seal the discharge hole 14, preventing the coupling agent from flowing out from the discharge hole 14 during long-term monitoring, which would cause insufficient coupling agent in the storage cavity 13, creating a cavity and affecting the detection of the probe 2.
