Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, and in particular to a postoperative wound care device for cardiac surgery. Background Technology
[0002] Most cardiac surgeries (such as coronary artery bypass grafting and valve replacement) require an open sternal incision (sternotomy) to access the thoracic cavity. Post-operatively, the sternum needs to be fixed with wires, and external pressure or traction must be avoided during the healing process. In the early postoperative period, sternal stability is poor; coughing, turning over, or external pressure can lead to suture breakage, sternal displacement, and even serious complications such as mediastinal infection. Furthermore, postoperative chest wound pain is significant, and direct contact or pressure can exacerbate the pain, affecting breathing, coughing, and early mobilization. When a regular blanket directly covers the chest: its weight compresses the wound, increasing pain and the risk of sternal instability; it obstructs airflow, leading to local sweating and dampness, increasing the probability of infection; and patients are afraid to touch the wound, hindering postoperative recovery (such as deep breathing and coughing to clear sputum). Based on this, this invention proposes a postoperative cardiac wound care device. Utility Model Content
[0003] The purpose of this invention is to provide a post-cardiac surgery wound care device to solve the problems mentioned above.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] This utility model discloses a post-cardiac surgery wound care device, comprising clamping mechanisms symmetrically arranged on both sides of a hospital bed, with a support mechanism inserted into the upper end of each clamping mechanism, and a plurality of blanket clamping mechanisms slidably arranged on the support mechanism; each blanket clamping mechanism includes an adjustable clamp assembly, which is slidably arranged on the support mechanism, and a connecting ring is provided at the top of the adjustable clamp assembly, with a clamp for clamping the blanket on the connecting ring.
[0006] Furthermore, the clamping mechanism includes a lower clamping plate, on one side of the upper end of the lower clamping plate, an integrally formed guide plate, a sliding groove is slidably fitted on the guide plate, and an upper clamping plate that mates with the lower clamping plate is integrally formed at the upper end of the sliding groove; a plurality of connecting bolts are symmetrically arranged between the upper and lower clamping plates, and the connecting bolts pass through the upper and lower clamping plates and are connected to adjusting nuts; a telescopic rod is provided at the upper end of the upper clamping plate, and a insertion groove is opened at the upper end of the telescopic rod, a support mechanism is inserted into the insertion groove, and the insertion groove and the support mechanism are connected together by screws.
[0007] Furthermore, a supplementary light is provided on the upper clamping plate, the supplementary light is electrically connected to the battery, the battery is located in the battery placement slot, and the battery placement slot is located on the upper clamping plate.
[0008] Furthermore, raised structures are provided on the opposing surfaces of the upper clamping plate and the lower clamping plate.
[0009] Furthermore, the telescopic rod has an outer telescopic cylinder and an inner sliding rod placed inside the outer telescopic cylinder. The outer telescopic cylinder has several through holes at equal intervals, and the inner sliding rod has spring protrusions that cooperate with the through holes.
[0010] Furthermore, the support mechanism includes an arched support plate, with plug-in blocks at both ends of the arched support plate; a hollow groove is provided at the center of the arched support plate for the adjustable clamp assembly to move.
[0011] Furthermore, the adjustable clamp assembly includes a lower clamp located below the arched support plate, a screw integrally formed at the center of the upper end face of the lower clamp, the upper clamp being threadedly connected to the screw, and the upper clamp located above the arched support plate; a rotating component integrally formed on the upper end face of the upper clamp, and an internal thread is formed on the inner sidewall of the rotating component.
[0012] Furthermore, the end of the screw away from the lower clamp has an annular hole through which the connecting ring passes.
[0013] Compared with the prior art, the beneficial technical effects of this utility model are as follows:
[0014] 1) Protect the wound: Prevent the blanket from directly compressing the chest wound, reducing pain and the risk of suture traction.
[0015] 2) Promote healing: Avoid local dampness and heat in the wound area to reduce the probability of infection.
[0016] 3) Improve comfort: Provide patients with space to move (such as arm movement) and reduce postoperative anxiety.
[0017] 4) Assisted sputum expectoration care: Patients can breathe more freely and cough to expel sputum (avoiding being afraid to exert force due to pain).
[0018] 5) Facilitates wound observation: After the stent is in place, medical staff can lift the blanket at any time to check the wound without frequently moving the patient.
[0019] 6) Assisting medical staff in wound disinfection and dressing changes: After the blanket is raised, a larger space is created between the patient's body and the blanket, giving medical staff a more spacious operating area when performing disinfection and dressing changes. This facilitates full exposure of the wound, makes it easier to retrieve and use instruments, and allows for more accurate and meticulous wound treatment, reducing errors or incomplete treatment caused by limited operating space.
[0020] 7) Provide sufficient lighting: The supplemental light can directly illuminate the wound area, providing bright and uniform light, allowing medical staff to clearly see every detail of the wound when changing dressings, including the condition of the sutures, the healing status of the wound edges, and whether there is bleeding or oozing, which helps to accurately judge the wound's recovery status and promptly detect potential problems.
[0021] In summary, this novel cardiac surgery wound care device indirectly promotes postoperative recovery by reducing pressure on the chest from the blanket, keeping the wound dry and breathable, avoiding friction or pulling on the wound, and facilitating wound disinfection and dressing changes for medical staff.

[0032] like Figure 1-5 As shown, a postoperative cardiac wound care device includes clamping mechanisms 1 symmetrically installed on both sides of a hospital bed. A support mechanism 2 is inserted into the upper end of the clamping mechanism 1, and several clamping mechanisms 3 are slidably installed on the support mechanism 2.
[0033] like Figure 2 As shown, the clamping mechanism 1 includes a lower clamping plate 101. A guide plate 102 is integrally formed on one side of the upper end of the lower clamping plate 101. A sliding groove 103 is slidably fitted on the guide plate 102. An upper clamping plate 104, which mates with the lower clamping plate 101, is integrally formed at the upper end of the sliding groove 103. Protrusions are formed on the opposing surfaces of the upper clamping plate 104 and the lower clamping plate 101 to increase the pressure of the clamping plates on the bed board and prevent slippage. A plurality of connecting bolts 105 are symmetrically installed between the upper clamping plate 104 and the lower clamping plate 101. The connecting bolts pass through the upper clamping plate 104 and the lower clamping plate 101 and are connected to adjusting nuts 106. Specifically, by adjusting the position of the sliding slot 103 on the guide plate 102, the upper clamping plate 104 and the lower clamping plate 101 are clamped onto the bed, and then the adjusting nut 406 is rotated to fix them so that they do not move.
[0034] A telescopic rod 109 is mounted on the upper end of the upper clamping plate 104. A slot is provided at the upper end of the telescopic rod 109, into which a support mechanism 2 is inserted. The slot and the support mechanism 2 are connected by screws. The support mechanism 2 can be quickly disassembled and installed using screws, the slot, and the screw holes on the sidewall of the slot. The telescopic rod 109 has an outer telescopic cylinder and an inner sliding rod placed inside the outer telescopic cylinder. The outer telescopic cylinder has several through holes spaced evenly, and the inner sliding rod has spring protrusions that mate with the through holes. Alternatively, in another embodiment of the telescopic rod, the inner sliding rod and the outer telescopic cylinder are fixed together using tightening bolts; this is existing technology and will not be elaborated further.
[0035] A supplementary light 108 is mounted on the upper clamping plate 104. The supplementary light 108 is electrically connected to a battery, which is located in a battery placement slot 107 on the upper clamping plate 104. The supplementary light 108 is supported by a flexible metal tube, allowing for easy adjustment of its position. The cable between the light and the battery is protected within the flexible metal tube (this is existing technology and will not be elaborated further).
[0036] like Figure 3 , 5As shown, the support mechanism 2 includes an arched support plate 201. Insertion blocks 203 are installed at both ends of the arched support plate 201, and the insertion blocks 203 have threaded holes for screw connections. A hollow groove 202 for the adjustable clamp assembly to move is provided at the center of the arched support plate 201. In this embodiment, the arched support plate 201 is a widened structure to improve the supporting force of the cover, and the hollow groove 202 achieves weight reduction. The arched support plate 201 can be selected with a suitable sag (the vertical distance from the arch apex to the arch foot, an important parameter describing the height of the arch structure; a larger sag indicates a higher arch structure, and a smaller sag indicates a lower arch structure) to meet the height requirements of the cover.
[0037] like Figure 4 As shown, the clamping mechanism 3 includes an adjustable clamp assembly, which is slidably mounted on the support mechanism 2. A connecting ring 305 is mounted on the top of the adjustable clamp assembly, and a clamp 306 for clamping the cover is mounted on the connecting ring 305. The connecting ring 305 may be an open ring. The adjustable clamp assembly includes a lower clamp 301 located below the arched support plate 201. A screw 302 is integrally formed at the center of the upper end face of the lower clamp 301. An annular hole for the connecting ring 305 to pass through is opened at the end of the screw 302 away from the lower clamp 301. An upper clamp 303 is threadedly connected to the screw 302, and the upper clamp 303 is located above the arched support plate 201. A rotating assembly 304 is integrally formed on the upper end face of the upper clamp 303, and an internal thread is opened on the inner sidewall of the rotating assembly 304. Specifically, by rotating the rotating component 304, the position of the upper clamp 303 is adjusted, thereby achieving the pressing and fixing of the upper and lower clamps on the arched support plate 201.
[0038] The operation process of this utility model is as follows:
[0039] First, according to the patient's position requirements, the symmetrically distributed clamping mechanisms 1 are fixed to the bed board; then, the support mechanism 2 is inserted into the upper end of the clamping mechanism 1; next, several blanket clamping mechanisms 3 are used to clamp and fix the upper edge of the blanket, so that the support mechanism 2 can support the upper part of the blanket; finally, according to the actual situation, the height of the blanket can be adjusted by adjusting the extension and retraction of the telescopic rod 109.
[0040] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
