Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a wound dressing changing device for thoracic surgery patients. Background Art

[0002] Thoracic surgery patients usually have diseases or injuries involving the heart, lungs, and other organs in the chest cavity. Common diseases include lung cancer, heart disease, esophageal disease, and pleural disease. These patients may receive a variety of treatments, such as surgery, radiotherapy, chemotherapy, or medical treatment.

[0003] For example, for patients with fluid or gas accumulation problems, a common medical procedure in thoracic surgery is drainage, which aims to remove excess fluid, gas or pus from the body to relieve symptoms and promote healing.

[0004] When replacing the saline solution required for drainage in the drainage bottle of the prior art, the medical staff first clamps the drainage tube connected to the catheter on the top of the drainage bottle at any position with a medical clamp, and the patient needs to assist in pressing the clamp to prevent it from loosening. At this time, the medical staff's hands are freed, and then the medical staff rotates and removes the threaded cover threadedly connected to the top opening of the drainage bottle. Some of them use a plug-in rubber plug structure to achieve the sealing of the top opening, so it is necessary to manually pull out the sealing cover, and then the waste water in the drainage bottle can be poured out into a pre-prepared garbage basin. After pouring, take out a bottle of unopened saline solution and pour it upside down from the top opening. The invention relates to a series of operations for replacing saline solution in a drainage bottle, wherein the patient is instructed to manually loosen the clamp after the threaded cap is screwed tightly, so as to complete a series of operations for replacing saline solution. However, the above-mentioned replacement of saline solution requires a series of operations such as manually clamping to stop the flow, unscrewing or pulling off the sealing cap, etc., which makes the operation steps cumbersome. At the same time, the rubber stopper may be difficult to pull out due to excessive plugging. In addition, the patient's assistance is required. If the patient cannot take care of himself or is asleep at night, he cannot help the medical staff to replace the saline solution in the drainage bottle, which brings inconvenience to the medical staff when replacing the saline solution. Therefore, the present application provides a wound dressing device for thoracic surgery patients to meet the needs. Summary of the invention

[0039] like Figure 1 and Figure 2 As shown, the embodiment of the present invention provides a wound dressing device for thoracic surgery patients, including a bottle body 1, a raised top opening 2 is integrally formed in the middle of the top of the bottle body 1, a sealing cover 21 is movably sleeved on the top of the top opening 2, a conduit 23 is fixedly connected to the middle of the top of the sealing cover 21, the bottom end of the conduit 23 extends to communicate with the interior of the bottle body 1, a drainage tube 3 is sleeved on the top of the conduit 23, an exhaust pipe 22 fixed to the sealing cover 21 is further provided on one side of the conduit 23, the bottom end of the exhaust pipe 22 extends to the interior of the bottle body 1, and the inner top wall of the sealing cover 21 is connected to the top of the circular structure. The plate 53 is fixedly connected to a rubber plug 51, and the bottom end of the rubber plug 51 is fixedly connected to a bottom plate 5 of a circular structure. The top plate 53, the rubber plug 51 and the middle of the bottom plate 5 are jointly provided with a through channel 52 for the conduit 23 and the exhaust pipe 22 to pass through. A convenient flow stopper 4 is installed on the sealing cover 21, and the convenient flow stopper 4 is also connected to the rubber plug 51; the convenient flow stopper 4 is used to clamp and stop the flow of the drainage tube 3 on the one hand, and to adjust the drainage size of the drainage tube 3 on the other hand, and to stop the flow while conveniently and quickly pulling the rubber plug 51 out of the top opening 2 at the same time.

[0040] like Figures 3 to 8 As shown, in order to facilitate the adjustment of the flow rate of the drainage tube 3 on the one hand and to stop the flow of the drainage tube 3 on the other hand, the convenient flow stopper 4 is provided, including a guide cylinder 41 fixed at the center of the top end of the sealing cover 21, the guide cylinder 41 is a conical funnel-shaped structure, the guide cylinder 41 surrounds the top opening 2 of the catheter 23, and reserves a gap for the bottom end of the drainage tube 3 to be sleeved on the top of the catheter 23, the guide cylinder 41 is used for guiding the drainage tube 3 when it is sleeved on the top of the catheter 23, and symmetrically distributed first grooves are provided on both sides of the top of the guide cylinder 41, and a pinching plate 43 is integrally formed on the inner bottom wall of the first groove through a weakened portion 42, and an extrusion protrusion 44 is provided on the opposite side wall of the two pinching plates 43, and the two extrusion protrusions 44 are used to clamp the drainage tube 3 to stop the flow and adjust the drainage The flow size, two symmetrically distributed anti-deflection blocks 415 are fixedly connected to the middle of the top of the guide cylinder 41, and the anti-deflection blocks 415 are vertically distributed with the pinching plate 43. The tops of the two anti-deflection blocks 415 are provided with second inclined surfaces 416, and the two second inclined surfaces 416 are symmetrically distributed. The second inclined surfaces 416 are used for preliminary guidance when the bottom end of the drainage tube 3 is sleeved on the top of the catheter 23. The middle of the side wall of the two anti-deflection blocks 415 facing each other is provided with an arc-shaped limiting groove 417 matching the outer diameter of the drainage tube 3. The edges of the side walls of the two anti-deflection blocks 415 facing each other are both fitted on the outer wall of the pinching plate 43. Second grooves are opened on the two side walls of the two pinching plates 43. The second grooves are fixed with tilting spring pieces 431, and the tilting portion at one end of the tilting spring piece 431 tilts out away from the middle direction of the extrusion protrusion 44.

[0041] like Figure 6As shown, both sides of the arc-shaped limiting groove 417 provided in the middle part of the side wall opposite to the two anti-deviation blocks 415 are set to be uneven structures, so that the friction coefficient of the tilting spring piece 431 can be increased when it is squeezed, so that the tilting spring piece 431 is tighter and firmer when it is squeezed. The setting of the second inclined surface 416 can enable the bottom end of the drainage tube 3 to cooperate with the setting of the two extrusion protrusions 44 when it is first installed on the top of the catheter 23, so that the bottom end of the drainage tube 3 can be quickly guided into the guide cylinder 41, and then the inner wall shape of the guide cylinder 41 is designed, so that the drainage tube 3 is more convenient and quick when it is sleeved on the top of the catheter 23. In addition, the setting of the two arc-shaped limiting grooves 417 makes it difficult for the drainage tube 3 to deviate forward and backward when the two extrusion protrusions 44 squeeze the drainage tube 3, so that the extrusion of the drainage tube 3 is more precise. At the same time, the arc-shaped limiting groove 417 can make the anti-deviation block 415 fit on the outer circumference of the drainage tube 3.

[0042] like Figures 3 to 8 As shown, in order to be able to stop the flow of the drainage tube 3 and simultaneously stretch the length of the rubber plug 51 to reduce the diameter of the rubber plug 51 so as to facilitate taking it out from the top opening 2, a push-pull rod 45 is hinged on the side wall opposite to each other of the two pinching plates 43, and the bottom ends of the two push-pull rods 45 are hinged with a transmission block 46. The two transmission blocks 46 are slidably sleeved on the outside of a guide rod 47 with a Z-shaped structure in a vertical section. The opposite ends of the two guide rods 47 are fixed to the outside of the guide cylinder 41, and the ends of the two guide rods 47 that are away from each other are provided with a blocking portion 48. The blocking portion 48 is used to block the transmission block 46 to prevent the transmission block 46 from escaping from the outside of the guide rod 47. The bottom ends of the two transmission blocks 46 are provided with an inclined portion 410, and the two inclined portions 410 are symmetrically distributed. The two ends of the two inclined portions 410 are respectively integrally formed with a high horizontal portion 49 and a low horizontal portion 411, and the high horizontal portion 49 and the low horizontal portion 411 are respectively arranged The bottom end of the transmission block 46 is arranged, and the ends of the two low-level horizontal parts 411 that are far from each other are fixedly connected with the anti-slip part 412 of the vertical structure. The bottom ends of the two high-level horizontal parts 49 are movably connected with the top ends of the pressure rods 414. The top ends of the two pressure rods 414 are provided with first inclined surfaces 4141 that match the inclined part 410. The bottom ends of the two pressure rods 414 are movably penetrated into the cavity provided on the inner side of the rubber plug 51 and are fixedly connected to the top end of the bottom plate 5. The outer side of the rubber plug 51 is corrugated. The rubber plug 51 has a structure in which the inner wall of the top opening 2 is provided with a corrugated groove that matches the outer shape of the rubber plug 51. The inner wall of the cavity of the rubber plug 51 is fixed with a plurality of supporting springs 413 in a ring array. The vertical cross-section of the supporting spring 413 is a C-shaped structure. The top and bottom ends of the supporting spring 413 are respectively fixed to the bottom end of the top plate 53 and the top end of the bottom plate 5. The outer side of the supporting spring 413 is provided with a plurality of equidistantly arranged arc-shaped matching parts 418 that match the shape of the corrugated groove.

[0043] Among them, some horizontal spacing is reserved between the end of the high horizontal part 49 away from the guide cylinder 41 and the connection part of the inclined part 410. Such a setting is required to adjust the flow rate of the drainage tube 3. When the first inclined surface 4141 is closer to the inclined part 410, the two squeezing protrusions 44 squeeze the drainage tube 3 to a greater extent, thereby making the flow rate in the drainage tube 3 smaller. When the inclined part 410 squeezes the first inclined surface 4141 until the top of the pressing rod 414 contacts the low horizontal part 411, the two squeezing protrusions 44 completely clamp the drainage tube 3 to stop the flow. The anti-detachment part 412 is set to prevent the top of the pressing rod 414 from detaching. Figure 7 As can be seen in the figure, the vertical section of the top plate 53 is a conical structure, and the top of the top opening 2 is provided with a profile matching the shape, so that the top plate 53 is more convenient and quick when the sealing cover 21 is sleeved on the top opening 2.

[0044] The workflow of the technical solution of the present invention is as follows:

[0045] When the operator replaces the physiological saline in the bottle 1, he can manually squeeze the two pinching plates 43 with all his strength, so that the two squeezing protrusions 44 clamp the outer side of the drainage tube 3, and when clamping, the anti-deviation block 415 acts to prevent the drainage tube 3 from deviating forward and backward during clamping and stopping the flow. In addition, with the help of the tilting spring pieces 431 provided on the two side walls of the pinching plates 43, the tilting parts of the tilting spring pieces 431 are squeezed when they come into contact with the uneven structure of the anti-deviation block 415, thereby quickly fixing the two pinching plates 43 and then quickly stopping the flow of the drainage tube 3. There is no need for medical staff to clamp the drainage tube 3 to stop the flow with medical clamps, which greatly improves the convenience of stopping the flow of the drainage tube 3.

[0046] Secondly, at the same time of the above-mentioned clamping and flow stopping, in conjunction with the setting of the push-pull rod 45, the two transmission blocks 46 are prompted to move relative to each other, and in conjunction with the setting of the inclined portion 410 and the first inclined surface 4141, the bottom inclined portion 410 of the transmission block 46 will squeeze the first inclined surface 4141 at the top of the pressing rod 414, and will drive the bottom plate 5 to move downward, and simultaneously drive the multiple supporting spring pieces 413 to perform stretching movement, so that the arc-shaped matching portions 418 provided on the multiple supporting spring pieces 413 are synchronously straightened. At the same time, the outer corrugated structure of the rubber stopper 51 will become flat, making its diameter smaller, and then the corrugated groove no longer restricts the outer shape of the rubber stopper 51, so that the rubber stopper 51 can be easily and quickly removed from the top opening 2 of the bottle body 1, so as to achieve the purpose of stopping the flow of the drainage tube 3 and facilitating the removal of the rubber stopper 51 at the same time, which brings convenience to medical staff when replacing the physiological saline in the bottle body 1 separately. Its structural design is simple, easy to use, and low in cost.

In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0048] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention.
