Description

Technical Field

[0001] This utility model relates to the technical field of waist circumference measurement devices, specifically a multifunctional device for measuring waist circumference. Background Technology

[0002] Abdominal distension is caused by fluid, gas, or masses in the abdomen due to various etiologies, which makes patients feel that their abdomen is full or can be seen to be distended. In colorectal clinical practice, abdominal distension is common. In this case, medical staff usually use a soft measuring tape to measure the patient's abdominal circumference. The conventional measurement method requires the patient to cooperate by raising their waist and buttocks so that the soft measuring tape can be passed under the patient's waist to take the measurement.

[0003] According to announcement number CN221013261U, a waist circumference measuring device is proposed, including a housing and a winding mechanism. End caps are fastened to both sides of the housing, and bearings are installed in the middle of the end caps. A mounting seat is provided in the middle of the housing. The winding mechanism is rotatably installed inside the housing, and a measuring tape is wound around its surface. A limit mechanism is installed inside the housing, and a retraction port is provided on the surface of the housing. When the measuring tape is pulled to measure the patient's waist circumference, the measuring tape drives the winding frame to rotate counterclockwise. The winding frame rotates inside the housing through the bearings at both ends of the rotating shaft, thus pulling the measuring tape out of the winding frame. The rotation of the rotating shaft drives the coil spring inside the mounting seat to rotate and store force. After the measurement is completed, the measuring tape is released, and the coil spring releases force, causing the winding frame to rotate clockwise, thus winding up the measuring tape. This makes the measuring tape easy to store without manual handling.

[0004] Given the current situation, critically ill patients are unable to cooperate with medical staff to elevate their waist and hips independently. Furthermore, some patients with abdominal distension and pain are even less able to cooperate due to the pain. Therefore, it is necessary to use external force from the measurer to elevate the patient, which can easily cause discomfort and aggravate the patient's pain, while also increasing the physical burden on the measurer. Secondly, when measuring the patient's waist circumference using conventional methods, the patient's body will press against the measuring tape, which is prone to errors. Moreover, when multiple measurements are required, repeated friction on the patient's skin not only causes discomfort but also increases the risk of damage to the patient's skin integrity. In response to the problems mentioned above, an improved multifunctional device for measuring waist circumference has been proposed. Utility Model Content

[0026] 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.

[0027] Please see Figures 1-4 This utility model provides a multifunctional device for measuring abdominal circumference, including an auxiliary body 1 with a height of 6-11 cm and a length of 5 cm. It also includes a movable groove 2, an extension rod 3, a positioning component 4, and a locking mechanism 5. The movable groove 2 is formed on the auxiliary body 1, and the extension rod 3 is movably connected within the inner cavity of the movable groove 2. The positioning component 4 is movably connected to the extension rod 3. The locking mechanism 5 is installed on the auxiliary body 1 and located on both sides of the extension rod 3. First scale lines 6 are provided on both sides of the auxiliary body 1, and second scale lines 7 are provided on the surface of the extension rod 3. Through the cooperation of the auxiliary body 1, the movable groove 2, the extension rod 3, and the locking mechanism 5, the patient experience can be optimized and the burden on the patient reduced. During the measurement process, the patient can complete the abdominal circumference measurement without changing their body position. For severely ill or immobile patients, this greatly reduces discomfort. Simultaneously, the retractable, scaled extension rod 3 is fixed to the locking mechanism 5, allowing the measuring device to adapt to patients of different body types and measurement needs, ensuring measurement flexibility while improving measurement accuracy.

[0028] In this embodiment, as Figure 3 As shown, there are two movable slots 2 on the main body 1 of the auxiliary device. The two movable slots 2 are respectively set as a horizontal slot and a vertical slot. There are two extension rods 3. The two extension rods 3 are respectively installed inside the horizontal slot and the vertical slot. By setting the movable slots 2 as horizontal slots and vertical slots, it is convenient to install the extension rods 3 in different directions, so that medical staff can easily measure and calculate the patient's abdominal circumference.

[0029] In this embodiment, as Figure 3As shown, limit blocks 8 are fixedly connected to both sides of the extension rod 3. Limit grooves 9 are opened on the inner wall of the movable groove 2 at positions corresponding to the limit blocks 8. The limit blocks 8 are movably connected inside the limit grooves 9. By setting the cooperation between the limit blocks 8 and the limit grooves 9, the extension rod 3 can move in the movable groove 2, and at the same time, it achieves the function of limiting during the movement, thereby enhancing the stability of the extension rod 3 when it moves.

[0030] In this embodiment, as Figure 3 and Figure 4 As shown, the locking mechanism 5 includes a fixing block 51, which is fixed in a symmetrical position at the opening of the movable groove 2 and located on both sides of the extension rod 3. A threaded sleeve 52 is embedded on the surface of the fixing block 51, and a positioning screw 53 is threadedly connected to the inner cavity of the threaded sleeve 52. A rubber block 54 is installed at one end of the positioning screw 53, and one side of the rubber block 54 is in contact with the limiting block 8 on the extension rod 3. An adjusting block 55 is fixedly connected to the other end of the positioning screw 53. By setting the fixing block 51, the threaded sleeve 52 can be easily fixed. With the cooperation of the threaded sleeve 52 and the positioning screw 53, medical staff can rotate the adjusting block 55, which will drive the rubber block 54 on the positioning screw 53 to move towards the limiting block 8. Thus, the rubber block 54 and the limiting block 8 are in contact, achieving the fixing effect of the rubber block 54 on the extension rod 3 at different positions. This prevents the position of the extension rod 3 from changing again, allowing the measuring device to adapt to patients with different body shapes and measurement needs, ensuring measurement flexibility while improving measurement accuracy.

[0031] In this embodiment, as Figure 3 As shown, multiple anti-slip grooves are provided around the surface of the adjusting block 55. The distance between two adjacent anti-slip grooves is equal. By setting the anti-slip grooves, the friction of the surface of the adjusting block 55 can be increased, so that medical staff will not slip when rotating the adjusting block 55.

[0032] Preferred, such as Figure 5 As shown, the positioning component 4 includes a hollow groove 41 and a positioning rod 42. One end of the positioning rod 42 is fixed in the movable groove 2. The hollow groove 41 is opened on the extension rod 3. The other end of the positioning rod 42 passes through the hollow groove 41 and is fixedly connected to a locking block 43. The locking block 43 is located in the hollow groove 41 and is movably connected. Through the cooperation of the hollow groove 41 and the positioning rod 42, the position of the extension rod 3 in the movable groove 2 can be limited, thus preventing the extension rod 3 from separating from the movable groove 2.

[0033] Furthermore, such as Figure 6As shown, a buckle 10 is installed on the extension rod 3 at the lower end of the auxiliary device body 1. The inner cavity of the buckle 10 is engaged with a soft ruler 11 that works with the extension rod 3 and the auxiliary device body 1. One end of the soft ruler 11 is equipped with a locking strip 12. The buckle 10 can provide a locking function for one end of the soft ruler 11, so that the other end of the soft ruler 11 can be used to measure around the patient's abdomen, avoiding the need for medical staff to fix both ends of the soft ruler 11 with both hands at the same time during measurement.

[0034] It is worth noting that, such as Figures 1-4 As shown, the auxiliary device body 1 has grooves on its opposite side walls, and a magnet 13 is embedded in the grooves. The magnet 13 installed on the outside of the auxiliary device body 1 simplifies the storage and carrying process of the auxiliary device body 1, making the auxiliary device body 1 portable and not easy to lose.

[0035] The upper edge of the assistive device body 1 is chamfered to prevent medical staff from scratching it during measurement, thus improving the safety of the assistive device body 1.

[0036] In practical use, when medical staff measure a patient's abdomen, first, the flexible measuring tape 11 with the clip 12 is passed through the buckle 10 on one of the extension rods 3. Then, the main body 1 of the assist device is placed on both sides of the patient. Next, the extension rod 3 in the transverse groove is stretched outwards to the point where the patient's lower back contacts the outermost part of the bed surface. Values ​​c1 and c2 are measured through the second graduation line 7 on the extension rod 3 in the transverse groove. Then, the flexible measuring tape is used to measure the value a around the patient's upper abdomen from the point where the patient's lower back contacts the outermost part of the bed surface. Next, the extension rod 3 in the longitudinal groove is stretched upwards, and the diameter between the two extension rods 3 is measured again through the flexible measuring tape 11 to obtain the value b. Simultaneously, when stretching the extension rods 3 in the transverse and longitudinal grooves, it is necessary to... The threaded sleeve 52 can be easily fixed by the fixing block 51 in the snap-fit ​​mechanism 5. With the cooperation of the threaded sleeve 52 and the positioning screw 53, the medical staff can rotate the adjusting block 55. The adjusting block 55 drives the rubber block 54 on the positioning screw 53 to move towards the limiting block 8, so that the rubber block 54 and the limiting block 8 fit together. This achieves the fixing effect of the rubber block 54 on the extension rod 3 at different positions, preventing the position of the extension rod 3 from changing again. This allows the measuring device to adapt to patients with different body shapes and measurement needs, ensuring measurement flexibility while improving measurement accuracy. Finally, the scale needs to be aligned during the measurement process to ensure measurement accuracy. Finally, the patient's abdominal circumference can be measured according to the measurement formula: a + b - c1 - c2.
