Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a general surgical incision recovery and care device and its operation method. Background Technology

[0002] Following general surgery, the wound healing process typically consists of four stages: hemostasis, inflammation, proliferative phase, and remodeling. The hemostasis and inflammation phases are critical windows for determining the quality of wound healing. During the hemostasis phase, it is essential to rapidly control wound bleeding, remove accumulated blood, and prevent hematoma formation. During the inflammation phase, effective drainage of inflammatory exudate is crucial, infection prevention is necessary, and local application of anti-infective or healing-promoting medications may be required. Currently, clinical care often utilizes gauze dressings, negative pressure drainage balls, or traditional elastic bandages. However, these methods offer limited functionality and cannot simultaneously achieve the synergistic effects of pressure hemostasis, continuous drainage, and medication delivery using a single device.

[0003] Traditional general surgical wound care has the following main shortcomings when dealing with the hemostasis and inflammation phases: Hemostasis requires pressure from elastic bandages, drainage necessitates the placement of separate drainage tubes, and medication administration requires frequent dressing changes. The alternating use of multiple devices not only increases the workload of medical staff but also causes secondary damage to newly formed granulation tissue due to repeated tearing of dressings.

[0004] Traditional elastic bandages rely heavily on experience for pressure application, making it difficult to quantify the appropriate pressure. Excessive pressure can lead to local ischemia and necrosis, while insufficient pressure results in poor hemostasis. Drainage devices are mostly passive, unable to actively adjust the drainage intensity based on the amount of exudate.

[0005] Most existing medicated dressings are pre-impregnated, which release drugs quickly but make it difficult to maintain an effective concentration; or they require micro-electronic pumps for precise drug delivery, which are costly and complex in structure, making them unsuitable for widespread use in primary hospitals.

[0006] A search revealed Chinese patent CN 222341439 U, which discloses a surgical wound healing and care device. The device includes a care frame and an outer cover hinged to it. A placement plate is mounted on the inner side of the outer cover. Both the outer cover and the placement plate have ventilation holes. Elastic limiting members are symmetrically arranged on the inner side of the outer cover, and mounting plates are slidably connected to these elastic limiting members. Fixing members are symmetrically arranged at the ends of the care frame and outer cover away from the hinge. Connecting blocks are symmetrically installed at both ends of the care frame, with straps inserted into each connecting block, and connecting members are mounted on the connecting blocks. This application allows for a large exchange of air between the inside and outside, and prevents bacteria carried by the incoming air, thus avoiding affecting the healing speed of the patient's wound. Furthermore, the position of the elastic limiting members can be adjusted according to the size of the gauze, thereby compressing and limiting the gauze. It offers good performance and flexible use.

[0007] The nursing devices in the prior art cannot achieve continuous drug administration and simultaneous drainage of exudate. They need to be repeatedly disassembled before medication can be changed, which increases the workload of nursing operations. Summary of the Invention

[0008] To address the problems existing in the prior art, this application provides a novel general surgical wound recovery care device, designed to provide care for the two stages of wound recovery: the hemostasis stage and the inflammation stage. By alternating between a replaceable hemostasis and pressure module and a drainage and drug delivery module inside the base, pressure hemostasis during the hemostasis stage and drainage and drug delivery during the inflammation stage can be achieved on the same base, avoiding the irritation to the wound caused by repeatedly changing the entire device, and improving the continuity of care and patient comfort.

[0009] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows: This application provides a general surgical incision recovery and care device, including a base and a cover plate disposed on the base. A care mechanism is disposed inside the base, and a care pad is disposed at the bottom of the base. A pressure relief valve is connected to the cover plate and the pressure relief valve is connected to the care mechanism. The care mechanism includes a hemostasis and pressure module and a drainage and drug administration module, which are alternately disposed in the base at different care stages.

[0010] It should be noted that the nursing pad is made of silicone, which fits comfortably against the patient's skin.

[0011] Furthermore, the technical solution includes a nursing support sleeved within a base, with multiple liquid guide tubes running through the nursing support. Each liquid guide tube contains a liquid absorption block, and a corrugated sleeve is connected to the top of the liquid guide tube. A movable plate is connected between two adjacent corrugated sleeves, and a piston push rod is connected to the movable plate. Multiple drainage tubes also run through the nursing support, with a set of drainage tubes symmetrically arranged on both sides of each piston push rod. A medicine cylinder is connected to each drainage tube, and a piston cylinder is connected between each set of medicine cylinders. The piston cylinder and piston push rod cooperate with each other and are connected to a pressure relief valve.

[0012] It should be noted that the corrugations on the corrugated sleeve can achieve folding and shrinking as well as extension and elongation.

[0013] More specifically, the liquid-absorbing block is fitted with an extendable corrugated cylinder, the bottom of which is fixedly connected to the liquid-guiding cylinder, and the liquid-absorbing block has a cross-shaped structure. The corrugated cylinder allows control over the vertical expansion of the liquid-absorbing block.

[0014] Specifically, the base is a hollow, rounded rectangular box structure with openings at the top and bottom, and a limiting platform is provided on the inner wall of the bottom of the base along the circumferential direction, and the nursing support is erected on the limiting platform.

[0015] Furthermore, the hemostasis and pressure module and the drainage and drug delivery module also include a one-way valve disposed in the drainage tube and a surgical wound care pad disposed below the nursing support, wherein the upper end face of the surgical wound care pad is connected to the bottom of the drainage tube.

[0016] Furthermore, the hemostasis and pressure module also includes a pressure airbag connected to the bottom of each of the drainage tubes, and the bottom of each pressure airbag is connected to the upper surface of the incision care pad.

[0017] Furthermore, the drainage and drug delivery module also includes a drug delivery head connected to the bottom of each of the drainage tubes, the end of which is inserted into the incision care pad.

[0018] Specifically, the drug delivery head is provided with multiple drug delivery tubes.

[0019] Preferably, each of the liquid medicine cylinders is provided with a rubber stopper at its upper opening.

[0020] Preferably, the nursing pad is provided with straps.

[0021] This application provides a method for operating a general surgical wound recovery and care device, including the following steps: The base and nursing pad containing the hemostasis and pressure module are covered by a strap and then pressure is applied to the incision to stop the bleeding. After hemostasis is achieved, the hemostasis and pressure module in the base is replaced with a drainage and drug delivery module. The drainage and drug delivery module is used to drain the exudate and deliver the drug to the incision site.

[0022] Compared with the prior art, the beneficial effects of the present invention are: This invention achieves full coverage of wound care from initial pressure hemostasis to mid-to-late stage drainage and drug administration by setting up an alternating hemostasis and drainage and drug administration module. It does not require replacing the entire device, but only switching the internal functional modules, making it convenient to operate and reducing the risk of secondary injury.

[0023] This invention limits the maximum pressure of the pressurized airbag by using a mechanical pressure relief valve to prevent excessive pressure from causing tissue damage; at the same time, it controls the drug delivery rate of the drug delivery head to avoid the release of large amounts of drug in a short period of time, thus achieving a safe, controllable and continuous therapeutic effect.

[0024] This invention utilizes the principle that after the absorbent block absorbs the leaking fluid, its expansion causes the corrugated sleeve to extend. The extension of the corrugated sleeve reduces the internal pressure, creating a negative pressure that effectively promotes fluid absorption and drainage. Simultaneously, as the corrugated sleeve extends, it pushes the movable plate upward, causing the piston rod to move upward in the piston cylinder. This increases the pressure in the piston cylinder and transmits it to the medication cylinder. When the pressure exceeds the one-way valve threshold, the one-way valve opens, and the medication is delivered from the medication head to the incision care pad and distributed around the wound, thus achieving the technical effect of continuous drainage and medication administration.

[0027] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "front end", "rear end", "inner side", "outer side", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0029] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0030] The inventors discovered in clinical practice that existing surgical wound care devices have relatively limited functions and cannot simultaneously achieve the synergistic effects of pressure hemostasis, continuous drainage, and drug delivery on the same device, which undoubtedly increases the cost and workload of nursing care.

[0031] Based on the above-mentioned problems, this application provides a general surgical incision recovery and care device, which realizes the alternation of different care stages through multiple care modules pre-set in the same base, thereby effectively improving the efficiency and effect of incision care.

[0032] Example 1 Reference Figure 1-2 As shown, this application provides a general surgical incision recovery and care device, including a base 1 and a cover plate 2 disposed on the base 1. The base 1 has a hollow rounded rectangular box structure, and a receiving cavity is formed inside it. A care mechanism 3 is detachably disposed in the receiving cavity.

[0033] As an example, a limiting platform is provided circumferentially on the bottom inner wall of the base 1, and the nursing mechanism 3 is mounted on the limiting platform, which facilitates the disassembly of the nursing mechanism 3.

[0034] Preferably, the base 1 is made of a transparent material to facilitate observation of the operation of the internal care mechanism 3.

[0035] Furthermore, a nursing pad 4 is fixedly connected to the bottom of the base 1. The nursing pad 4 is made of flexible medical silicone material and is used to conform to the skin around the patient's incision. A cover plate 2 is fastened to the upper opening of the base 1. A pressure relief valve 5 is also installed through the cover plate 2. Specifically, the adjustment knob on the pressure relief valve 5 is rotatably connected to the cover plate 2. When replacing the nursing mechanism 3, the adjustment knob on the pressure relief valve 5 is removed and the cover plate 2 is opened. The air inlet of the pressure relief valve 5 is connected to the interior of the nursing mechanism 3 and is used to regulate the air pressure inside the nursing mechanism 3.

[0036] The base 1 and the nursing pad 4 provide structural protection for the incision, preventing external pressure from causing the incision to reopen or causing pain to the patient. They also provide a mounting bracket for the internal nursing mechanism 3. In addition, the base 1 can reduce tension on the patient's incision site, preventing wound reopening during the recovery process and subsequent scar hyperplasia, thus playing a very positive role in the patient's incision recovery.

[0037] In this application, the nursing facility 3 includes a hemostatic pressure module and a drainage and drug administration module, which are alternately arranged in the base 1 at different nursing stages. Specifically, the hemostatic pressure module is mainly used for the hemostasis period in the early stage of wound healing, and the drainage and drug administration module is mainly used for the inflammatory period in the middle stage of wound healing.

[0038] Reference Figure 4 , 9 As shown in -14, the hemostasis and pressure module includes a nursing support 31 disposed in the base 1. The nursing support 31 is a rounded rectangular plate structure, and its four sides slide in fit with the inner wall of the base 1. After installation, the nursing support 31 is erected and fixed on the limiting platform provided on the bottom inner wall of the base 1.

[0039] In this embodiment, a plurality of liquid-guiding cylinders 32 are uniformly arranged along the length of the nursing support 31. Each liquid-guiding cylinder 32 is a cylindrical structure with openings at the top and bottom, and its interior is filled with an absorbent block 33. More specifically, the absorbent block 33 is covered with a corrugated cylinder, and the bottom of the corrugated cylinder is fixedly connected to the liquid-guiding cylinder 32. As an example, the absorbent block 33 can be made of medical superabsorbent resin sponge, which expands vertically after absorbing liquid due to the confinement of the corrugated cylinder.

[0040] Furthermore, a corrugated sleeve 34 is fixedly connected to the inner top of the liquid guiding cylinder 32. The corrugated sleeve 34 is a retractable rubber corrugated tube. A movable plate 35 is fixedly connected between the tops of two adjacent corrugated sleeves 34. A piston push rod 36 is vertically fixed on the movable plate 35.

[0041] Furthermore, the nursing support 31 is also provided with multiple guide tubes 37. A set of guide tubes 37 is symmetrically arranged on both sides of each piston push rod 36, with two guide tubes 37 in each set. A medicine cylinder 38 is fixedly connected to the upper end of each guide tube 37, and the medicine cylinder 38 is connected to the guide tube 37. A piston cylinder 39 is fixedly connected between the two symmetrically arranged medicine cylinders 38 in each set. For example, the piston cylinder 39 between the two medicine cylinders 38 is connected through a connecting pipe. The piston cylinder 39 cooperates with the piston push rod 36, causing the piston push rod 36 to move up and down within the piston cylinder 39, and the piston cylinder 39 is connected to the pressure relief valve 5. For example, the piston cylinder 39 and the pressure relief valve 5 are connected through a pressure relief pipe.

[0042] Preferably, each guide tube 37 is provided with a one-way valve 310, which only allows the medium to flow from the medicine cylinder 38 to the bottom of the guide tube 37. A surgical incision pad 311 is provided below the nursing support 31. The surgical incision pad 311 is made of medical non-woven fabric, and its upper end is sealed to the bottom edge of each guide tube 32. A pressure airbag 312 is connected to the bottom of each guide tube 37. The pressure airbag 312 is made of elastic rubber material, and its bottom is connected to the upper end of the surgical incision pad 311.

[0043] As an example, the incision care pad 311 can be connected to the liquid guide tube 32 and the pressurized air bag 312 by adhesive bonding, thereby facilitating the replacement of the incision care pad 311.

[0044] In this embodiment, each medicine cylinder 38 is equipped with a rubber stopper 6 at its upper opening for injecting gas or medicine into the medicine cylinder 38 using a syringe. The nursing pad 4 has symmetrically arranged straps 7 on both sides; the straps 7 are elastic Velcro straps used to secure the device to the patient's body.

[0045] Example 2 Based on the embodiments, refer to Figure 1-3 As shown in Figures 5-8, the difference between this embodiment and Embodiment 1 is that the nursing mechanism 3 is a drainage and drug delivery module. This drainage and drug delivery module also includes a nursing support 31, a liquid guide tube 32, a liquid absorption block 33, a corrugated sleeve 34, a movable plate 35, a piston push rod 36, a drainage tube 37, a drug delivery cylinder 38, a piston cylinder 39, a one-way valve 310, and a surgical wound care pad 311, and their connection relationships are the same as in Embodiment 1.

[0046] The difference between this embodiment and Embodiment 1 is that the bottom of each guide tube 37 is no longer connected to a pressurized airbag 312, but instead connected to a drug delivery head 313. The drug delivery head 313 is provided with multiple hollow capillaries, the ends of which are inserted downwards into the incision care pad 311, thereby enabling the drug delivery head 313 to deliver the medication to the incision care pad 311 and distribute it around the wound to achieve the purpose of administering medication to the incision site.

[0047] In use, the piston cylinder 39 is driven by the piston push rod 36 to deliver the liquid medicine in the medicine cylinder 38 through the guide tube 37 and the administration head 313 to the area below the incision care pad 311, where it acts on the incision site. At the same time, any leakage at the incision site can be absorbed by the absorbent block 33 in the liquid guide tube 32 and drained upwards.

[0048] Specific application examples The specific application of the general surgical incision recovery and care device of this application in the general surgical incision healing and care process is now described in detail with reference to Embodiment 1 and Embodiment 2.

[0049] Postoperative wound care is crucial in general surgery. In the early postoperative period, effective pressure bandaging is necessary to prevent bleeding and hematoma formation. In the later stages of recovery, timely drainage of exudate and blood is essential, along with medication to prevent infection and promote healing. Currently, the common clinical approach is to first apply pressure bandages with gauze or bandages to stop bleeding, later replacing them with dressings that provide drainage and medication. This often requires multiple dressing changes, increasing the workload for medical staff and increasing the risk of secondary injury to the wound due to improper technique. Furthermore, it doesn't allow for a quick and convenient switch between pressure hemostasis and drainage / medication functions.

[0050] To address the inconveniences in the aforementioned clinical nursing procedures, this application provides a general surgical incision recovery and care device, the specific usage of which is as follows: In the initial hemostasis stage after surgery: the hemostasis and pressure module is installed into the base 1, the incision care pad 311 is aligned with the patient's incision position, and the device is fixed by the strap 7.

[0051] The pressure bladder 312 applies initial pressure to the incision site to stop bleeding. When bleeding occurs, it is absorbed by the suction block 33, causing the suction block 33 to expand continuously. The expansion of the suction block 33 causes the corrugated sleeve 34 to extend. When the corrugated sleeve 34 extends, it pushes the movable plate 35 upward, causing the piston rod 36 to move upward in the piston cylinder 39. This increases the pressure in the piston cylinder 39 and transmits it to the medicine cylinder 38. At this time, no medicine is injected into the medicine cylinder 38; it is only used as an airway for the pressure bladder 312. When the pressure exceeds the threshold of the one-way valve 310, the one-way valve 310 opens, and gas flows from the medicine cylinder 38 through the guide tube 37 to the pressure bladder 312, causing the pressure bladder 312 to expand continuously, thus pressurizing the incision site.

[0052] During the pressurization process of the pressurized airbag 312, the maximum pressure of the pressurized airbag 312 is controlled and limited by the pressure relief valve 5 to prevent excessive pressurization from causing tissue damage.

[0053] Recovery and nursing stage: After the wound has stopped bleeding and entered the healing period, untie the bandage 7, open the cover plate 2, take out the hemostasis and pressure module in the base 1, and then put the drainage and drug delivery module into the base 1, and fix it again with the bandage 7.

[0054] Exudate at the incision site is absorbed by the absorbent block 33, causing it to expand continuously. This expansion causes the corrugated sleeve 34 to extend, increasing its internal volume and creating negative pressure, which effectively promotes drainage. Simultaneously, the extension of the corrugated sleeve 34 pushes the movable plate 35 upward, causing the piston rod 36 to move upward within the piston cylinder 39. This increases the pressure in the piston cylinder 39 and transmits it to the medication cylinder 38. When the pressure exceeds the threshold of the one-way valve 310, the one-way valve 310 opens, allowing the medication to flow from the medication cylinder 38 through the guide tube 37 to the medication head 313 and then to the wound, achieving continuous drainage and medication delivery.

[0055] To achieve continuous drug delivery, the threshold of the pressure relief valve 5 is set slightly higher than the threshold at which the one-way valve 310 in the guide tube 37 opens. This allows the drug delivery rate to be controlled by adjusting the threshold of the hydraulic valve 5, thus preventing the release of large amounts of drug in a short period of time and achieving a safe, controllable, and continuous therapeutic effect.

[0056] During the nursing process, the absorbent block 33 and the incision care pad 311 can be disassembled and replaced as needed.

[0057] It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this invention, and these should also be considered within the scope of protection of this invention. These modifications and improvements will not affect the effectiveness of the invention or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
