Description

Technical Field

[0001] This utility model relates to a medical wristband, specifically a medical wristband that prevents patients from removing it themselves. Background Technology

[0002] In healthcare settings, it has become standard practice for patients to wear wristbands to quickly and accurately display and record critical patient information, such as name, age, bed number, allergy history, symptoms, and important medical instructions. This information is crucial for ensuring patient safety, improving diagnostic and treatment efficiency, and preventing medical errors.

[0003] However, existing patient wristband designs have some significant shortcomings in terms of structure and user experience. Most wristbands use simple materials and fastening methods, such as plastic straps with Velcro or disposable plastic buckles. While these designs are inexpensive to manufacture, they are not very secure and cannot meet the needs of prolonged wear. Especially for children, the elderly, or patients with special psychological states (such as being uncooperative, mischievous, or resistant), the wristbands are easily torn off and discarded, causing inconvenience and challenges for medical staff in obtaining patient information.

[0004] Therefore, how to redesign or improve the wristband to avoid the defects of being easily torn off and discarded by patients has become an urgent problem to be solved in this field. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology described above by proposing a medical wristband that prevents patients from removing it themselves. It can be securely worn on the patient's wrist, effectively preventing the patient from tearing it off and ensuring the smooth operation of medical staff in obtaining patient information.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] A medical wristband designed to prevent patients from removing it themselves includes a wristband body and an unlocker. The wristband body has an information recording section on its surface and includes a connecting section and a fixing section respectively located at both ends. The connecting section and the fixing section are detachably connected, causing the wristband body to form a ring. The fixing section is provided with a locking mechanism, and the connecting section is provided with an anti-detachment structure. The anti-detachment structure is adapted to lock onto the locking mechanism to prevent the connecting section from detaching from the fixing section. The unlocker is adapted to the locking mechanism to release the locking mechanism from locking the connecting section.

[0008] Preferably, the locking mechanism includes a locking rod and a magnetic buckle. The locking rod is fixedly disposed on the surface of the fixing part, and the magnetic buckle is movably disposed relative to the wristband body. The magnetic buckle has a locking hole, into which the locking rod can be inserted and automatically locked. The unlocker is provided with a strong magnet. When the unlocker contacts or approaches the magnetic buckle, the magnetic buckle unlocks the locking rod. The anti-detachment structure includes at least one hole through which the locking rod can pass.

[0009] Preferably, the magnetic latch includes a lock body and a lock core portion built into the lock body. The lock core portion includes a column ring, at least two elastic locking plates, and a magnetic block. The inner cavity of the column ring forms the lock hole. The column ring has side holes with the same number as the elastic locking plates. The elastic locking plates are provided with locking teeth and inclined flaps. A cavity is left between the upper end face of the column ring and the inner side of the lock body. The elastic locking plates are evenly arranged around the column ring, and the locking teeth of each elastic locking plate are embedded in the side holes and extend to the lock hole. The inclined flaps of each elastic locking plate extend to the cavity and are fixedly connected to the lock body. The magnetic block is movably disposed in the cavity. The magnetic block is located between the upper end face of the column ring and the inclined flaps. The upward movement of the magnetic block applies pressure to the inclined flaps, causing the elastic locking plates to shift outward. The side wall of the lock rod is provided with an annular lock groove. After the lock rod is inserted into the lock hole, it continues to advance until the locking teeth automatically spring into the annular lock groove.

[0010] Preferably, the locking tooth has a flat end face and a beveled end face. The flat end face is perpendicular to the axis of the lock hole, and the beveled end face is located below the flat end face and extends into the side hole away from the axis of the lock hole. When the locking rod is inserted into the lock hole, it contacts and applies force to the beveled end face to push the locking tooth outward. When the annular locking groove passes the locking tooth, the locking tooth automatically springs into the annular locking groove under the action of elastic force, while the flat end face locks the annular locking groove to prevent the locking rod from disengaging.

[0011] Preferably, the unlocker includes a main body and a handheld part. The main body is provided with a positioning concave surface that adapts to the external shape of the lock body. The positioning concave surface is fitted and fastened to the lock body from above. The strong magnet is located in the middle of the positioning concave surface. When the positioning concave surface is fastened to the lock body, the strong magnet generates a magnetic attraction effect on the magnetic block.

[0012] Preferably, a flexible connecting rope is provided between the magnetic buckle and the fixing part.

[0013] Preferably, the end of the fixing part is provided with a limiting ring for the connecting part to pass through.

[0014] Compared with existing technologies, the medical wristband that uses the above-mentioned technical solution to prevent patients from removing it themselves has the following beneficial effects:

[0015] The wristband body is fixedly connected at both ends by locking rods and magnetic buckles. After the locking rod passes through the hole in the wristband body, it can be automatically locked in the lock hole, making it simple and convenient for patients to wear. It also has better locking stability, and even if the patient has a strong desire to take it off, it is difficult to unlock it easily, effectively ensuring that the wristband is securely worn on the patient's wrist.

[0016] The unlocker, designed independently of the wristband itself, is specifically adapted to the magnetic buckle. Under normal circumstances, patients cannot open the magnetic buckle by themselves using other tools. The wristband can only be removed after medical or nursing work is completed, or with the permission of medical staff. This helps ensure the proper wearing of the wristband, and in turn, facilitates patient management in medical settings.

[0017] The magnetic buckle is connected to the wristband body by a flexible connecting cord, which not only does not hinder the use of the magnetic buckle, but also prevents the magnetic buckle from being lost or swallowed by the patient when it is not locked, thus providing higher safety.

[0018] In addition to the above-mentioned technical solution, this utility model also discloses the following technical solution:

[0019] The wristband body is equipped with a positioning chip, which establishes signal transmission with an external smart terminal via a wireless network. The external smart terminal can be a mobile phone, a nurse station computer, or a monitoring device.

[0020] This solution allows smart terminals to monitor the location of patients wearing wristbands in real time and receive alerts when patients move away from the controlled area, enabling them to respond quickly and preventing patients from leaving the area without permission.

[0029] The present invention will now be further described with reference to the accompanying drawings.

[0030] Example 1:

[0031] like Figures 1 to 8 The aforementioned medical wristband designed to prevent patients from removing it themselves includes a wristband body 1 and an unlocker 2. The wristband body 1 has an information recording section 10 on its surface for recording and displaying the patient's identity information and medical information. The wristband body 1 includes a connecting section 11 and a fixing section 12 respectively located at both ends. The connecting section 11 and the fixing section 12 are detachably connected, causing the wristband body 1 to form a loop for wearing on the patient's wrist.

[0032] The fixing part 12 is provided with a locking mechanism, and the connecting part 11 is provided with an anti-detachment structure. The anti-detachment structure is adapted to lock the locking mechanism to prevent the connecting part 11 from detaching from the fixing part 12. The unlocker 2 is adapted to the locking mechanism to unlock the locking mechanism from locking the connecting part 11.

[0033] Specifically, the locking mechanism includes a locking bar 3 and a magnetic buckle 4. The locking bar 3 is vertically fixed to the surface of the fixing part 12. A flexible connecting rope 15 is provided between the magnetic buckle 4 and the fixing part 12 to prevent the magnetic buckle 4 from detaching from the wristband body 1 and being lost or swallowed by the patient. The magnetic buckle 4 has a locking hole 41, into which the locking bar 3 can be inserted and automatically locked. The anti-detachment structure includes four holes 14 through which the locking bar 3 can pass, and the four holes 14 are equidistant along the length of the wristband body 1.

[0034] The magnetic latch 4 includes a lock body 40 and a lock core portion built into the lock body 40. The lock core portion includes a pin ring 42, at least two elastic locking plates 43 and a magnetic block 45. The inner cavity of the pin ring 42 forms a lock hole 41. The pin ring 42 is provided with side holes 420 in the same number as the elastic locking plates 43. The elastic locking plate 43 is made of elastic metal or hard plastic. The bottom of the elastic locking plate 43 is provided with locking teeth 430 and the top of the elastic locking plate 43 is provided with inclined folding plate 431. A cavity 44 is left between the upper end face of the column ring 42 and the inner side of the lock body 40. The elastic locking plates 43 are evenly arranged around the column ring 42, and the locking teeth 430 of each elastic locking plate 43 are embedded in the side hole 420 and extend into the lock hole 41. The inclined folding plate 431 of each elastic locking plate 43 extends obliquely upward to the upper part of the cavity 44, and the upper end of the inclined folding plate 431 is fixedly connected to the lock body 40. The magnetic block 45 is a cylindrical stainless steel block. The magnetic block 45 can be moved up and down in the cavity 44. The magnetic block 45 is located between the upper end face of the column ring 42 and the inclined folding plate 431. When not under magnetic force, the bottom of the magnetic block 45 rests on the upper end face of the column ring 42, and the top of the magnetic block 45 is just about to contact the lower surface of the inclined folding plate 431. When the magnetic block 45 is moved upward by the magnetic force, it applies pressure to the inclined folding piece 431, causing the elastic locking piece 43 to shift outward.

[0035] The locking tooth 430 has a flat end face and an inclined end face. The flat end face is perpendicular to the axis of the lock hole 41, and the inclined end face is located below the flat end face and extends into the side hole 420 away from the axis of the lock hole 41. The side wall of the locking rod 3 is provided with an annular locking groove 30. When the locking rod 3 is inserted into the lock hole 41, it contacts and applies force to the inclined end face. The inclined end face is pushed outward by the force. When the annular locking groove 30 passes the locking tooth 430, the locking tooth 430 automatically springs into the annular locking groove 30 under the action of elasticity. At the same time, the flat end face locks the annular locking groove 30 to prevent the locking rod 3 from disengaging, thus completing the locking of the locking rod 3.

[0036] The unlocker 2 is independent of the wristband body 1. The unlocker 2 includes a main body 20, a handheld part 21, and a strong magnet 22. The bottom of the main body 20 has a positioning concave surface adapted to the external shape of the lock body 40. The positioning concave surface is fitted onto the lock body 40 from above. The strong magnet 22 is located in the middle of the positioning concave surface. When the positioning concave surface is engaged with the lock body 40, the strong magnet 22 exerts a magnetic attraction on the magnetic block 45, causing it to move upward. The inclined flaps 431 of all the elastic locking pieces 43 are simultaneously subjected to the pressure of the magnetic block 45. The elastic locking pieces 43 deviate outward, causing the locking teeth 430 to disengage from the annular locking groove 30. The magnetic lock 4 releases the lock on the multi-locking rod 3.

[0037] In addition, a limiting ring 13 is provided at the end of the fixing part 12 for the connecting part 11 to pass through. When wearing the wristband, the connecting part 11 is passed through the limiting ring 13 and then connected to the fixing part 12. The limiting ring 13 can restrict the wristband body from swinging or shifting relative to the connection point, ensuring stable and comfortable wearing.

[0038] Example 2:

[0039] This embodiment is based on the technical solution of Embodiment 1. The technical differences between this embodiment and Embodiment 1 are as follows:

[0040] The wristband body 1 is equipped with a positioning chip, which establishes signal transmission with an external smart terminal via a wireless network. This external smart terminal can be a mobile phone, a nurse station computer, or a monitoring device. Through the networked positioning chip, the smart terminal (such as a nurse's or caregiver's mobile phone) can monitor the patient's location in real time and receive alerts when the patient moves away from the monitored area, allowing for a rapid response and helping to prevent patients from leaving the area without permission.

[0041] The above are preferred embodiments of this utility model. For those skilled in the art, several modifications and improvements can be made without departing from the principle of this utility model, and these should also be considered within the protection scope of this utility model.
