Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a quick-adjusting buckle for patient limb fixation straps used during CT examinations. Background Technology

[0002] During CT scans, patients need to maintain a specific posture and avoid limb movement to ensure image quality and accuracy. Therefore, limb immobilization straps have been developed. Traditional straps typically use simple Velcro or buckle designs, which can immobilize the patient's limbs to some extent, but they have some problems in practical use.

[0003] Traditional fixation straps are often complicated to adjust. For example, Velcro straps require repeated pasting and adjustment, and buckle-type straps also require time to align and fasten. In time-sensitive scenarios such as CT scans, this can affect examination efficiency. Furthermore, some traditional fixation straps are not user-friendly in terms of materials and design, such as having rough edges or lacking soft padding, which can easily cause friction and pressure on the patient's skin, leading to discomfort during the examination. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a quick-adjusting buckle for patient limb fixation straps during CT examinations.

[0005] This utility model is achieved by the following technical solution: a quick-adjusting buckle for fixing a patient's limb during CT examination, including a fixing strap body, a T-shaped groove at the top of the fixing strap body, a T-shaped slider slidably connected to the inner wall of the T-shaped groove, and the top of the T-shaped slider being fixedly connected to the bottom of the elastic fixing strap.

[0006] Through the above technical solution, the cooperation between the T-shaped slider and the T-shaped groove allows the elastic fixation band to slide flexibly on the fixation band body. This allows the position of the elastic fixation band to be quickly adjusted according to the different limb thickness or fixation needs of different patients, achieving effective fixation and personalized adjustment of the patient's limb. The structural design of the T-shaped groove allows the T-shaped slider to be quickly inserted and removed, facilitating the quick replacement of the elastic fixation band when needed, thus improving the convenience and efficiency of operation.

[0007] As a further improvement to the above solution, a number of limiting fixing holes are provided on the surface of the fixing belt body.

[0008] Through the above technical solution, several limiting and fixing holes opened on the surface of the fixation belt can be selected to insert locking pins at appropriate positions according to the actual situation of the patient's limb, thereby adjusting the fixing position and tightness of the fixation belt and improving the flexibility and comfort of fixation.

[0009] As a further improvement to the above solution, a number of the limiting and fixing holes are fitted with locking pins on their inner walls, and the top of the locking pins is engaged with the bottom of the magnetic lock head.

[0010] With the above technical solution, after the locking pin is inserted into the limiting and fixing hole, it engages with the magnetic buckle lock head, which can quickly lock the fixation strap. The operation is simple and convenient, improving the operating efficiency of medical staff. The engagement method between the magnetic buckle lock head and the locking pin is firm and reliable, ensuring that the fixation strap will not loosen or fall off due to the patient's limb movement during use, thus ensuring the stability of the fixation.

[0011] As a further improvement to the above solution, an elastic wristband pad is fixedly connected to the inner wall of the elastic fixing band.

[0012] Through the above technical solution, the elastic fixation band itself has elasticity, which can expand and contract according to the shape and movement of the patient's limb. It is neither too tight, causing patient discomfort, nor too loose, affecting the fixation effect. It can adapt to the different thicknesses of patients' limbs, improving the comfort and stability of fixation. Its top end is fixedly connected to the T-shaped slider, and its bottom end is connected to the elastic wristband pad, effectively connecting all components together to ensure that the fixation band will not loosen or fall off during use, thus guaranteeing the reliability of fixation. When fixing the patient's limb, the elastic wristband pad directly contacts the patient's limb, playing a role in cushioning and protection, avoiding pressure or friction damage to the patient's limb caused by the fixation band, and improving the patient's comfort during CT examination.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention utilizes a T-shaped groove and a T-shaped slider design to allow the elastic fixation band to slide flexibly on the fixation band body. This feature is extremely useful in CT scans because different patients have limbs of varying sizes. This sliding adjustment method allows for quick adjustment of the elastic fixation band's position to accommodate different patients' limbs, achieving effective fixation. Furthermore, the elastic fixation band can be replaced as needed, improving the equipment's practicality.

[0015] Multiple limiting and fixing holes on the surface of the fixation strap provide a variety of fixation position options. The locking pins can be inserted into different limiting and fixing holes and then engaged with the magnetic lock head, so that the most suitable fixation position can be selected according to the actual situation of the patient's limb, thereby improving the stability and comfort of fixation;

[0016] This invention utilizes an elastic wristband pad fixed to the inner wall of an elastic fixation band. When fixing the patient's limb, this pad can directly contact the limb, providing cushioning and protection, preventing the fixation band from causing pressure or friction damage to the patient's limb, and improving the patient's comfort during CT examinations.

[0017] Elastic fixation straps are inherently elastic. This elasticity allows the straps to stretch and contract according to the shape and movement of the limbs when fixing them, ensuring they are neither too tight to cause discomfort nor too loose to affect the fixation effect, thus further improving patient comfort.

[0018] The magnetic buckle and locking pin mechanism makes locking and unlocking the fixation strap very convenient. When it is necessary to immobilize a patient's limb, simply engage the magnetic buckle and locking pin to complete the fixation; after the examination, gently separating the magnetic buckle and locking pin allows for quick release of the fixation strap, improving the operational efficiency of medical staff.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] Example:

[0027] Please combine Figure 1-4 The quick-adjustment buckle for patient limb fixation straps during CT examinations in this embodiment includes a fixation strap body 1. A T-shaped groove 7 is provided at the top of the fixation strap body 1. A T-shaped slider 8 is slidably connected to the inner wall of the T-shaped groove 7. The top of the T-shaped slider 8 is fixedly connected to the bottom of the elastic fixation strap 5. When it is necessary to replace the elastic fixation strap 5, simply remove the T-shaped slider 8 from the T-shaped groove 7 to easily replace the new elastic fixation strap 5. The operation is simple and quick, improving the maintenance and usage efficiency of the equipment.

[0028] The surface of the fixation strap body 1 is provided with limiting fixation holes 2. Several limiting fixation holes 2 are provided, and the locking pins 3 can be inserted into the appropriate positions according to the actual situation of the patient's limb, so as to adjust the fixation position and tightness of the fixation strap.

[0029] Several limiting and fixing holes 2 have locking pins 3 attached to their inner walls. After the locking pins 3 are inserted into the limiting and fixing holes 2, they engage with the magnetic buckle lock head 4, which can quickly lock the fixing belt. The operation is simple and convenient, improving the operating efficiency of medical staff.

[0030] The top of the locking pin 3 is engaged with the bottom of the magnetic lock head 4. The engagement between the magnetic lock head 4 and the locking pin 3 is firm and reliable, ensuring that the fixation strap will not loosen or fall off due to the patient's limb movements during use, thus ensuring the stability of the fixation.

[0031] The inner wall of the elastic fixation strap 5 is fixedly connected to an elastic wrist pad 6, which plays a role in cushioning and protection, and avoids the fixation strap from causing pressure or friction injury to the patient's limb.

[0032] The implementation principle of the quick-adjustment buckle for patient limb fixation during CT examination in this embodiment is as follows: First, medical staff adjust the position of the elastic fixation band 5 by sliding the T-shaped slider 8 within the T-shaped groove 7 according to the thickness of the patient's limb, so that the elastic fixation band 5 roughly covers the limb part that needs to be fixed. Then, the locking pin 3 is inserted into the appropriate limiting fixation hole 2. When selecting the limiting fixation hole 2, it is necessary to consider both ensuring effective fixation of the patient's limb and patient comfort. Finally, the magnetic buckle lock head 4 is engaged with the locking pin 3 to complete the fixation of the patient's limb. At this time, the elastic wristband pad 6 is in contact with the patient's limb, and the elastic fixation band 5 generates appropriate elasticity according to the shape and state of the patient's limb to ensure the stability and comfort of the fixation. If it is found that the fixation position is not suitable or the patient feels uncomfortable during the fixation process, medical staff can easily open the engagement between the magnetic buckle lock head 4 and the locking pin 3, pull the locking pin 3 out of the current limiting fixation hole 2, reselect a suitable limiting fixation hole 2, and re-engage and lock it. If the overall position of the elastic fixing band 5 needs to be adjusted, it can be achieved by sliding the T-shaped slider 8 within the T-shaped groove 7.

[0033] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
