Description

Technical Field

[0001] This utility model relates to the field of sensor fixation technology, and more specifically to a fixation device for a continuous central venous pressure and invasive blood pressure monitoring sensor. Background Technology

[0002] Central venous pressure (CVP) and invasive blood pressure monitoring play a crucial role in clinical medicine. Central venous pressure refers to the pressure in the right atrium and the superior and inferior vena cava or pulmonary artery, reflecting important indicators such as blood volume, cardiac function, and vascular tone. However, in practical clinical applications, the fixation of central venous pressure and invasive blood pressure sensors faces numerous challenges, requiring the use of fixation devices for installation and securement.

[0003] As shown in the prior art published in CN217611042U, although this prior art uses two clamping parts to cooperate and fix the blood pressure sensor to the support column, and a fastening assembly to cooperate with the clamping parts to fix the blood pressure sensor to the clamping parts, thus achieving the effect of convenient use. The device for fixing the blood pressure sensor provided by this prior art has the effect of making it convenient for medical staff to fix the blood pressure sensor at the required height. However, the steps for fixing the sensor in this prior art are relatively cumbersome, requiring multiple operations to cooperate with the fastening assembly and clamping parts, and the sensor cannot be adjusted according to needs after fixing, which affects the operational convenience of the technical solution. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides a fixation device for a continuous central venous pressure and invasive blood pressure monitoring sensor. Through the extensibility of the first spring, the spacing between two locking plates can be adjusted by inward movement, achieving a sensor-switching effect and facilitating removal. Then, the rebound force of the first spring pushes the locking plates outward, and the outward pushing force of the locking plates limits and fixes the sensor, thereby achieving convenient sensor installation and removal. Simultaneously, it can be directly fixed to the patient's arm, ensuring the zero point is always at the same level as the heart, reducing the workload of resetting to zero due to changes in body position, guaranteeing the accuracy of real-time monitoring data, and greatly facilitating operation by medical personnel, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fixation device for a continuous central venous pressure and invasive blood pressure monitoring sensor, comprising a positioning component installed on the top of a support plate for fixing the sensor, and an auxiliary component provided on the outside of the support plate for adjusting the angle of the positioning component;

[0006] The positioning component includes a fixed bracket installed on the top of the support plate. A movable shaft is rotatably connected inside the fixed bracket. A through hole is opened on the outside of the movable shaft, and a support shaft is installed inside the through hole. Both ends of the support shaft are fitted with clamping plates, and the tops of the two clamping plates are respectively provided with clamping grooves on the side that is far apart from each other.

[0007] A first spring is sleeved on the outside of the support shaft, and the first spring is located between the two clamping plates.

[0008] In a preferred embodiment, fixed shafts are installed at both ends of the movable shaft, and a fixing hole is provided on one side of the fixed shaft corresponding to the fixed shaft, with the fixed shaft located inside the fixing hole.

[0009] In a preferred embodiment, the auxiliary component includes a groove formed on the front side of the movable shaft, a guide post is installed inside the groove, and a second spring is sleeved on the outside of the guide post. Both ends of the second spring are provided with movable plates sleeved on the outside of the guide post, and positioning posts are installed on the sides of the two movable plates that are far apart from each other.

[0010] The fixed bracket has multiple spaced positioning slots on one side of the positioning column at both ends, and the end of the positioning column away from the moving plate extends into one of the positioning slots.

[0011] In a preferred embodiment, an elastic memory spring is installed at the bottom end of the support plate.

[0012] In a preferred embodiment, anti-slip strips are installed on both sides of the top of the card plate.

[0013] In a preferred embodiment, both the cross-section of the card plate and the cross-section of the through hole are rectangular, and the outer side of the card plate is in contact with the inner wall of the through hole.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. By utilizing the telescopic properties of the first spring, the two clamping plates can be adjusted inward to achieve the effect of misaligning the clamping plates with the sensor, thus facilitating its removal. Then, the rebound force of the first spring pushes the clamping plates outward, and the outward pushing force of the clamping plates limits and fixes the sensor, thereby achieving the effect of convenient sensor installation and removal.

[0016] 2. By engaging the fixed shaft with the fixed hole, the movable shaft can be rotated around the fixed hole as the center, thereby adjusting the placement angle of the sensor. Then, the rebound force of the second spring pushes the moving plate outward, and the positioning pin on the moving plate is embedded in the corresponding positioning groove. The engagement between the positioning pin and the positioning groove limits the movable shaft, thus fixing the adjusted sensor.

[0017] 3. The automatic rewinding effect of the elastic memory spring allows medical staff to tie the elastic memory spring to the patient's upper arm at the level of the heart, which can improve the patient's wearing comfort. At the same time, by fixing it directly to one side of the patient's arm, the zero point can be kept at the same level as the heart at all times, reducing the workload caused by resetting to zero due to changes in body position, ensuring the accuracy of real-time monitoring data, and making it very convenient for medical staff to operate.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Refer to the instruction manual appendix Figure 1-5 This utility model provides a fixation device for a continuous central venous pressure and invasive blood pressure monitoring sensor, including a positioning component installed on the top of a support plate 1 for fixing the sensor, and an auxiliary component for adjusting the angle of the positioning component is provided on the outside of the support plate 1.

[0026] The positioning component includes a fixed bracket 2 installed on the top of the support plate 1. A movable shaft 3 is rotatably connected inside the fixed bracket 2. A through hole 4 is opened on the outside of the movable shaft 3, and a support shaft 5 is installed inside the through hole 4. Both ends of the support shaft 5 are fitted with clamping plates 6. A groove 7 is opened on the side of the top of the two clamping plates 6 that are far apart. A first spring 8 is fitted on the outside of the support shaft 5. The first spring 8 is located between the two clamping plates 6.

[0027] In use, the two locking plates 6 are supported by the first spring 8, allowing medical staff to operate them with two fingers to move them inward, thus adjusting the distance between them. This facilitates inserting the two locking plates 6 into the corresponding holes on the sensor. Releasing the locking plates 6 allows them to move outward using the rebound force of the first spring 8, thereby limiting and fixing the sensor with the outward pushing force of the locking plates 6. It also allows the two locking plates 6 to be displaced from the sensor, thus achieving convenient sensor installation and removal. Furthermore, the anti-slip strips 18 installed on both sides of the top of the locking plates 6 enhance the friction between the medical staff's hands and the locking plates 6, thereby improving the stability of the locking plates 6 and preventing them from coming loose.

[0028] At the same time, to ensure the stability of the displacement of the clamping plate 6, it is necessary to limit the clamping plate 6, such as... Figure 4 and 5 As shown, the cross-section of the card plate 6 and the cross-section of the through hole 4 are both rectangular, and the outside of the card plate 6 is in contact with the inner wall of the through hole 4. By making the cross-section of the card plate 6 and the cross-section of the through hole 4 both rectangular, the through hole 4 can limit the card plate 6, thereby ensuring the stability of the card plate 6 when it is displaced and avoiding swaying.

[0029] Because patients have different body shapes, the placement of the sensors needs to be adjusted accordingly, such as... Figure 1-3 As shown, fixed shafts 9 are installed at both ends of the movable shaft 3, and a fixed hole 10 is opened on one side of the fixed shaft 9 corresponding to the fixed shaft 9. The fixed shaft 9 is located inside the fixed hole 10. The auxiliary component includes a groove 11 opened on the front side of the movable shaft 3. A guide post 12 is installed inside the groove 11, and a second spring 13 is sleeved on the outside of the guide post 12. Movable plates 14 are sleeved on both ends of the second spring 13 outside the guide post 12, and positioning posts 15 are installed on the side of the front ends of the two movable plates 14 that are far apart. Multiple positioning grooves 16 are opened on the side of the fixed bracket 2 corresponding to the positioning posts 15, and the end of the positioning post 15 away from the movable plate 14 extends into one of the positioning grooves 16.

[0030] In use, because the fixed shaft 9 engages with the fixed hole 10, medical staff can rotate the movable shaft 3 around the fixed hole 10. This allows for adjustment of the placement angle of the sensor fixed by the clamping plate 6. To ensure the stability of the adjusted sensor, the two movable plates 14 can be moved inward, separating the positioning post 15 from the positioning groove 16. This facilitates the rotation of the unrestricted movable shaft 3. Then, the rebound force of the second spring 13 pushes the movable plate 14 outward, causing the positioning post 15 on the movable plate 14 to embed into the corresponding positioning groove 16. This engagement between the positioning post 15 and the positioning groove 16 limits the movement of the movable shaft 3, thus ensuring the stability of the sensor after adjustment.

[0031] Because the sensors are all fixed in one place, patients can only move their limbs in a limited space, which affects their comfort. Figure 1 and 3 As shown, an elastic memory spring 17 is installed at the bottom of the support plate 1. Through the automatic rewinding effect of the elastic memory spring 17, medical staff can tie the elastic memory spring 17 to the outside of the patient's limb (such as the arm), so that the sensor can move with the patient, which can improve the accuracy of detection and also improve the patient's wearing comfort.

[0032] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
