Abstract
Description
Technical Field
[0001] This application relates to the field of assistive device technology, and in particular to a fixation device for a PDA. Background Technology
[0002] In clinical nursing work, nurses not only need to measure patients' vital signs, but also need to treat and care for patients according to doctors' orders. Nursing staff place the necessary items and medicines on the treatment cart for easy operation.
[0003] In the process of clinical nursing and treatment, medical staff may not be able to record all patient information in a timely manner. In order to facilitate and simplify the clinical workflow, reduce the workload of medical staff, and alleviate work pressure, large hospitals now equip medical staff with medical PDAs, also known as medical handheld terminals. These devices integrate core functions such as patient information management, medical order execution, and vital sign entry. They interact with the hospital information system in real time through a wireless network, becoming nurses' "mobile workstations".
[0004] In clinical applications, PDAs are often placed haphazardly on the treatment cart surface. They may fall due to movement or collisions with the cart, causing screen breakage, malfunctions, and increased maintenance costs. Furthermore, treatment carts frequently come into contact with blood, disinfectants, or medications; if the PDA is splashed with liquid, it may damage the circuitry or contaminate the device surface, leading to data loss or hospital-acquired infections. Such situations can significantly impact nurses' work efficiency and potentially delay procedures in emergencies. Utility Model Content

[0034] Please see Figure 1 , Figure 2 and Figure 5One or more embodiments provide a fixing device for a PDA, including a substrate 100, a base plate 101 on the front side of the substrate 100, clamping plates 102 on both sides of the substrate 100 and above the base plate 101, the clamping plates 102 being L-shaped, a groove being formed inside the clamping plates 102, a rubber pad 103 being provided on the inner wall of the groove, and elastic particles 104 being filled in the sealed space limited by the groove and the rubber pad 103. The device also includes a PDA 200, the bottom of the PDA 200 abutting against the top of the base plate 101, the surface of the rubber pad 103 abutting against the surface of the PDA 200, a fixing component being provided on the back side of the substrate 100, an infrared temperature probe 201 being provided on the top of the PDA 200, and anti-slip textures being formed on the surface of the rubber pad 103.
[0035] In this embodiment, the fixing device is fixed to the handrail of the treatment cart using a fixing component. When used by medical personnel, the PDA 200 is inserted into the clamping space defined by the substrate 100, base plate 101, and clamping plate 102. The PDA 200 is clamped and fixed by the elastic action of the rubber pad 103 and elastic particles 104, thus enabling the placement of the PDA 200 during medical operations. When using the PDA 200, medical personnel can simply grasp both sides of the PDA 200 and pull it away from the fixing device, effectively ensuring the PDA 200 is securely held in place. The PDA200 extends its service life while improving the work efficiency of medical staff. The anti-slip texture increases the friction between the rubber pad 103 and the PDA200, further ensuring the PDA200 is firmly fixed. The PDA200 uses existing technology and integrates infrared body temperature measurement with the infrared temperature probe 201. A heart rate monitor can be added to the PDA as needed to achieve heart rate monitoring. A blood oxygen saturation clip can also be added to achieve blood pressure monitoring, effectively enriching the functions of the PDA200.
[0036] Please see Figure 2 , Figure 3 and Figure 4 In some embodiments, the fixing assembly includes a first arc plate 105 and a second arc plate 106. A limiting groove 107 is formed inside the substrate 100. A lifting threaded rod 108 is movably connected to the bottom of the inner wall of the limiting groove 107. A lifting block 109 is threadedly connected to the surface of the lifting threaded rod 108. The first arc plate 105 is detachably connected to the back of the lifting block 109. The second arc plate 106 is detachably connected to the back of the substrate 100 and is located below the first arc plate 105. The other end of the lifting threaded rod 108 extends to the outside of the substrate 100. Elastic protrusions 117 are provided on the surfaces of both the first arc plate 105 and the second arc plate 106.
[0037] In this embodiment, when the fixing component is fixed, the second arc plate 106 abuts against the lower part of the handrail of the treatment cart. Then, the lifting threaded rod 108 is rotated to make the lifting block 109 rise and fall, thereby driving the first arc plate 105 to move towards the second arc plate 106 until the first arc plate 105 and the second arc plate 106 clamp the handrail of the treatment cart, thereby satisfying the position fixation of the fixing device. With the help of the fixing component, the fixing device can be fixed at different positions or angles on the handrail of the treatment cart to meet the needs of different medical staff. The setting of the elastic protrusion 117 increases the friction between the first arc plate 105 and the second arc plate 106 and the handrail of the treatment cart, and improves the fixing firmness between the fixing component and the handrail.
[0038] Please see Figure 3 In some embodiments, a first limiting threaded rod 110 is provided on the front side of the first arc plate 105, a first threaded hole is provided inside the lifting block 109, a second limiting threaded rod 111 is provided on the front side of the second arc plate 106, and a second threaded hole is provided on the back side of the substrate 100. The surface of the first limiting threaded rod 110 can be threadedly connected to the inner wall of the first threaded hole, and the surface of the second limiting threaded rod 111 can be threadedly connected to the inner wall of the second threaded hole.
[0039] In this embodiment, the first arc plate 105 is threadedly connected to the first threaded hole via the first limiting threaded rod 110, and the second arc plate 106 is threadedly connected to the second threaded hole via the second limiting threaded rod 111. This method allows the first arc plate 105 and the second arc plate 106 to be fixed to the lifting block 109 and the base plate 100, respectively. The first arc plate 105 and the second arc plate 106 have the same dimensions, and the first limiting threaded rod 110, the second limiting threaded rod 111, the first threaded hole, and the second threaded hole all have the same size and model. This prevents confusion between the first arc plate 105 and the second arc plate 106 in practical applications, thus avoiding the time spent by medical staff in distinguishing between them.
[0040] Please see Figure 3 and Figure 4 In some embodiments, the substrate 100 has five threaded holes 116 on both sides, and the surfaces of the first limiting threaded rod 110 and the second limiting threaded rod 111 can be threadedly connected to the inner wall of the five threaded holes 116.
[0041] In this embodiment, the first arc plate 105 and the second arc plate 106 are respectively threaded to the corresponding fifth threaded hole 116 by means of the first limiting threaded rod 110 and the second limiting threaded rod 111. At this time, the arc plate 105 and the second arc plate 106 are arc-shaped upwards, and medical staff can hang the corresponding medical supplies on the first arc plate 105 or the second arc plate 106.
[0042] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 In some embodiments, a suction cup 113 is also included. There are multiple suction cups 113. The front of the suction cup 113 is provided with a No. 3 limiting threaded rod 114. The back of the substrate 100 is provided with a No. 4 threaded hole 115 at the four corners. The surface of the No. 3 limiting threaded rod 114 can be threadedly connected to the inner wall of the No. 4 threaded hole 115. The surface of the No. 3 limiting threaded rod 114 can be threadedly connected to the inner wall of the No. 3 threaded hole 112. The bottom of the base plate 101 is provided with a No. 3 threaded hole 112. The surfaces of the No. 1 limiting threaded rod 110 and the No. 2 limiting threaded rod 111 can be threadedly connected to the inner wall of the No. 3 threaded hole 112.
[0043] In this embodiment, the suction cup 113 can be used to fix the fixing device on a set plane, such as part of the side panel of the treatment cart, to meet the fixing needs of different treatment carts or different positions. When the suction cup 113 is threadedly connected to the threaded hole 112 by the third limiting thread rod 114, the suction cup 113 is fixed. At this time, the first arc plate 105 and the second arc plate 106 are respectively connected to the corresponding threaded hole 111 by the first limiting thread rod 110 and the second limiting thread rod 111 on them to ensure the fixing needs of the suction cup 113. When the fixing device needs to be fixed by the fixing component, the suction cup 113 is threadedly connected to the threaded hole 112 by the third limiting thread rod 114, so that the suction cup 113 is fixed below the base plate 101 to ensure the application needs of the fixing component.
[0044] Specifically, the working principle of the PDA fixing device provided in this application is as follows:
[0045] When it is necessary to fix the device with the help of fixing components, the first arc plate 105 and the second arc plate 106 are respectively threaded to the corresponding first threaded hole and second threaded hole with the first limiting threaded rod 110 and the second limiting threaded rod 111. At this time, the first arc plate 105 is fixed on the lifting block 109, and the second arc plate 106 is fixed on the base plate 100. The second arc plate 106 is brought into contact with the lower part of the handrail of the treatment cart. Then, the lifting threaded rod 108 is rotated to make the lifting block 109 rise and fall, thereby driving the first arc plate 105 to move towards the second arc plate 106 until the first arc plate 105 and the second arc plate 106 clamp the handrail of the treatment cart, thereby satisfying the position fixation of the device. With the help of fixing components, the device can be fixed at different positions or angles on the handrail of the treatment cart to meet the needs of different medical staff.
[0046] When it is necessary to use the suction cup 113 to fix the device, the suction cup 113 is threadedly connected to the threaded hole 112 by the third limiting threaded rod 114, thereby fixing the suction cup 113. Then, the substrate 100 with the suction cup 113 is pushed towards the set plane, such as part of the side panel of the treatment cart, and the device is fixed by using negative pressure.
[0047] The unused arc-shaped plate 105 and arc-shaped plate 106 can be threaded to the corresponding threaded hole 116 by means of the first limiting thread rod 110 and the second limiting thread rod 111 respectively. At this time, the arc shape of arc-shaped plate 105 and arc-shaped plate 106 is upward. Medical staff can hang corresponding medical supplies on arc-shaped plate 105 or arc-shaped plate 106. Alternatively, arc-shaped plate 105 and arc-shaped plate 106 can be threaded to the corresponding threaded hole 116 by means of the first limiting thread rod 110 and the second limiting thread rod 111 respectively to ensure the fixation of suction cup 113.
[0048] The unused suction cup 113 can be threaded to the threaded hole 112 via the No. 3 limiting threaded rod 114, thereby fixing the suction cup 113 below the base plate 101 to ensure the application needs of the fixing component.
[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
