Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly to a drainage device for nursing pleural effusion. Background Art

[0002] Pleural effusion is a common clinical symptom characterized by pathological fluid accumulation in the pleural cavity. The pleural cavity is a potential gap between the visceral and parietal pleura. There are 5 to 15 ml of fluid in the pleural cavity of a normal person, which acts as a lubricant during respiratory movement. 500 to 1000 ml of fluid is formed and absorbed in the pleural cavity every day. Any reason that leads to increased production or reduced absorption of fluid in the pleural cavity can cause pleural effusion, chest tightness and dyspnea. When the effusion is small, the symptoms are not obvious. However, in the early stage of acute pleurisy, when the amount of effusion is small, there may be obvious chest pain, which worsens during inhalation. The patient prefers the affected side. When the effusion increases, the visceral and parietal layers of the pleura are separated, and the chest pain can be alleviated or disappear. When there is a moderate or large amount of pleural effusion, shortness of breath, chest tightness, palpitations, dyspnea, and even orthopnea accompanied by cyanosis may occur.

[0003] Closed thoracic drainage is to place one end of the drainage tube into the thoracic cavity and connect the other end to a water-seal bottle at a lower position to discharge gas or collect fluid in the thoracic cavity, so that the lung tissue can reopen and restore function. However, in daily use, since the catheter is relatively smooth and not firmly fixed, the catheter may slip out and fall with breathing movement or human accidental contact, thus causing harm to personnel.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the present invention, a deflection mechanism is provided in the annular plate so that when the patient moves, the drainage tube can move in the deflection mechanism, thereby ensuring the stability of the drainage tube during use. In addition, a positioning mechanism is provided on the outer wall of the annular sleeve, which can position the connecting portion on the drainage tube through the positioning mechanism, thereby further improving the firmness of the drainage tube. At the same time, the device is provided with a pressing mechanism on the basis of the positioning mechanism. In this way, when the positioning mechanism further positions the drainage tube, the pressing mechanism presses the wound of the patient to ensure the firmness of the wound of the patient.

[0017] 2. In the present invention, when the drainage tube is deflected by force, the deflection ball on the outside of the drainage tube is driven to deflect. At this time, the rotating rods 1 and 2 on the folding plates 1 and 2 rotate on the inner wall of the annular plate. Since the folding plates 1 and 2 are inclined, the deflection angle of the drainage tube has multiple directions, ensuring that the drainage tube will not fall off when subjected to force. At the same time, the slider 1 on the sliding rod slides in the sliding groove. At this time, the disc spring is deformed. When the force is over, the restoring force of the disc spring drives the slider 1 to reset, thereby ensuring the stability of the drainage tube in daily use.

[0018] 3. In the present invention, the reducing portion is driven to rotate by the supporting ring. When the reducing portion rotates, the increasing resistance surface contacts the tilting portion, thereby driving the pressing portion and the positioning portion on the joint portion to rotate, so that the positioning portion is stuck in the connecting portion on the outer wall of the drainage tube, thereby realizing the positioning of the drainage tube. In this way, in actual use, the drainage tube not only has its own locking function, but also cooperates with the external structure to fix the connecting portion of the drainage tube.

[0019] 4. In the present invention, when the moving ring moves downward, the spherical connecting mechanism drives the tilting rods on both sides to move downward synchronously. At this time, the moving rod on the tilting rod is displaced in the vertical direction, driving the annular ring at the bottom end of the moving rod to move downward, so that the annular ring squeezes the positioning film, thereby fixing the positioning film to the patient's wound again, ensuring the stability of the patient during treatment.

[0020] 5. In the present invention, by rotating the auxiliary ring, the clamping block and the inserting block on the auxiliary ring are not on the same axis. When the inserting block at the bottom end of the movable ring enters the through opening, the movable ring and the fixed ring fit together. The auxiliary ring is loosened and driven to rotate under the pressure of the second torsion spring. At this time, the clamping block is correspondingly inserted into the clamping groove, thereby achieving the fixation of the positioning mechanism and the locking mechanism.

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0035] Embodiment 1 further describes a drainage device for pleural effusion care proposed by the present invention, including a drainage tube 100, a drainage tube 101 is arranged on the upper end surface of the drainage tube 100, the drainage tube 101 includes a connecting portion 102, and also includes an annular suction cup 103, a plurality of groups of connecting plates 104 are arranged on the upper end surface of the annular suction cup 103 in a circumferential direction, an annular plate 105 is arranged between the plurality of groups of connecting plates 104, a deflection mechanism 200 is arranged on the inner wall of the annular plate 105, a deflection ball 106 is arranged in the deflection mechanism 200, an annular sleeve 107 is arranged on the upper end surface of the deflection ball 106, a positioning mechanism 300 is arranged on the outer wall of the annular sleeve 107, a pressing mechanism 400 is arranged on the positioning mechanism 300, an opening 108 is arranged in the deflection ball 106, and the drainage tube 101 passes through the annular sleeve 107 and the opening 108 correspondingly;

[0036] The pleural cavity is a potential cavity between the lungs and the chest wall. Under normal circumstances, the visceral pleura and the parietal pleura appear to have a thin layer of liquid, which acts as a lubricant during breathing. The pleural cavity and the liquid therein are not in a static state. The shape and pressure of the pleural cavity change greatly in each respiratory cycle, so that the liquid in the pleural cavity is continuously filtered out and absorbed and is in a dynamic balance. Various factors cause the liquid in the pleural cavity to form too quickly or be absorbed too slowly, that is, pleural effusion occurs. At present, when extracting the effusion from patients with pleural effusion, the drainage tube 100 and the drainage tube 101 are commonly used. A medical device for use, in a sterile environment, one end of a drainage tube 101 is placed in the chest cavity, and the other end is connected to a drainage tube 100 which is lower than the chest cavity outlet height, so as to discharge gas or collect liquid in the chest cavity, so that the lung tissue reopens and recovers its function. The first end of the drainage tube 101 is introduced into the patient's chest cavity, and the drainage tube 101 is attached to the patient's body by tape. However, in daily use, the catheter is relatively smooth and not firmly fixed, so that the catheter may slip out and fall with breathing movement or human accidental contact, thereby causing harm to personnel;

[0037] The device further improves the prior art by providing an annular suction cup 103 at the wound of the patient, the annular suction cup 103 is adsorbed on the human skin to ensure the positioning of the device, and six groups of connecting plates 104 are fixedly connected to the annular suction cup 103 in a circumferential direction, and an annular plate 105 is fixedly connected between the six groups of connecting plates 104, and a deflection mechanism 200 is provided in the annular plate 105, so that when the patient moves, the drainage tube 101 can move in the deflection mechanism 200, thereby ensuring the stability of the drainage tube 101 when in use. Furthermore, the annular sleeve 107 is fixedly connected to the deflection ball 106, and a positioning mechanism 300 is provided on the outer wall of the annular sleeve 107. The positioning mechanism 300 can be used to position the connection portion 102 on the drainage tube 101, thereby further improving the firmness of the drainage tube 101. At the same time, the device is provided with a pressing mechanism 400 on the basis of the positioning mechanism 300. Thus, when the positioning mechanism 300 further positions the drainage tube 101, the pressing mechanism 400 presses the wound of the patient to ensure the firmness of the wound of the patient.

[0038] The deflection mechanism 200 includes a sliding member 201 disposed in the annular plate 105, one end of the sliding member 201 is disposed on the deflection ball 106, a deflection member 202 is disposed in the annular plate 105, and the deflection member 202 is correspondingly disposed on the deflection ball 106. Figures 1 to 10 It can be seen that the deflection mechanism 200 cooperates with the sliding member 201 and the deflection member 202, so that the drainage tube 101 is offset at various angles when in use, which can not only ensure the stability of the drainage tube 101 when in use, but also enable the device to restrict the drainage tube 101 when the patient moves, thereby achieving a certain anti-falling effect;

[0039] The positioning mechanism 300 includes a rotating member 301 disposed on the annular sleeve 107, a positioning member 302 is disposed in the annular sleeve 107, the rotating member 301 and the positioning member 302 cooperate to position the drainage tube 101, a movable member 303 is disposed in the rotating member 301, and the movable member 303 cooperates with the rotating member 301. Since the drainage tube 101 may fall off due to contact at the catheter connection in the prior art, the present device further refines the structure of the annular sleeve 107. Figures 1 to 10 It can be seen that a rotating member 301 is provided on the outer wall of the annular sleeve 107, a positioning member 302 is provided inside the annular sleeve 107, a movable member 303 is provided inside the rotating member 301, and the movable member 303 moves in the vertical direction. At the same time, due to the deflection force of the groove structure, the rotating member 301 operates. When the rotating member 301 operates, the positioning member 302 is driven by the extrusion force to lock the connection of the drainage tube 101, so that the device has strong stability when in use;

[0040] The pressing mechanism 400 includes an adapting member 401 arranged on the movable member 303, a moving member 402 is arranged at one end of the adapting member 401, a pressing member 403 is arranged at the bottom end of the movable member 402, and the movable member 402 and the pressing member 403 cooperate to fix the wound. The device further refines the structure of the positioning mechanism 300, by providing an adapting member 401 on the movable member 303, the adapting member 401 drives the movable member 303 to operate synchronously when it moves, and since the moving member 402 and the pressing member 403 are arranged at one end of the adapting member 401, the pressing member 403 moves synchronously, thereby further fixing the patient's wound, and also includes a locking mechanism 500, the locking mechanism 500 includes an inserting member 501 arranged at the bottom end of the movable member 303, and an abutting member 502 cooperating with the inserting member 501 is arranged on the outer wall of the annular sleeve 107, the inserting member 501 and the abutting member 502 cooperate to fix the positions of the positioning mechanism 300 and the pressing mechanism 400, Figures 1 to 10 It can be known that the device is mainly locked by the cooperation between the insertion member 501 and the resistance member 502 .

[0041] Working principle: When in use, the device is firstly adsorbed on the outside of the patient's wound through the annular suction cup 103, and the drainage tube 101 is located in the deflection ball 106 and the annular sleeve 107. Figure 2 As shown, at this time, the resistance member 502 is driven to cause the resistance member 502 and the insertion member 501 to be misaligned, and then the adapting member 401 is pulled downward, and the movable member 303 in the adapting member 401 cooperates with the rotating member 301 to make the movable member 303 move in the vertical direction. At the same time, due to the deflection force of the groove structure, the rotating member 301 operates. When the rotating member 301 operates, the extrusion force drives the positioning member 302 to lock the connection of the drainage tube 101. Since the adapting member 401 drives the movable member 303 to operate synchronously when it moves, and the moving member 402 and the pressing member 403 are provided at one end of the adapting member 401, the pressing member 403 moves synchronously, thereby further fixing the patient's wound. At this time, the resistance member 502 is released, and under the reset of the spring, the insertion member 501 and the resistance member 502 cooperate to lock the entire device. In this way, the device achieves double-layer stability of the drainage tube 101 through the positioning mechanism 300 and the pressing mechanism 400.

[0042] Embodiment 2

[0043] The following technical features are added on the basis of the first embodiment: the sliding member 201 includes a slide groove 201a symmetrically arranged in the annular plate 105, a disc spring 201b is fixedly connected to the side wall of the slide groove 201a, one end of the disc spring 201b is fixedly connected to a slider 201c, the slider 201c is correspondingly slidably connected in the slide groove 201a, a sliding rod 201d is rotatably connected to the side wall of the slider 201c, one end of the sliding rod 201d is fixedly connected to the deflection ball 106, and the deflection The rotating member 202 includes a rotating rod 1 202a and a rotating rod 202b which are symmetrically connected to the inner wall of the annular plate 105, and a folding plate 1 202c and a folding plate 202d are correspondingly fixedly connected to the outer walls of the rotating rod 1 202a and the rotating rod 2 202b, and a deflection rod 1 202e and a deflection rod 2 202f are correspondingly fixedly connected to the folding plate 1 202c and the folding plate 2 202d, and one end of the deflection rod 1 202e and the deflection rod 2 202f is correspondingly fixed to the outer wall of the deflection ball 106;

[0044] Depend on Figures 3 to 10 It can be seen that the slide groove 201a is a groove of an arc structure provided on the inner wall of the annular plate 105, which is symmetrically provided on the inner wall of the annular plate 105, and the two sets of slide grooves 201a are symmetrically provided. A slider 201c is slidably connected in the slide groove 201a through a disc spring 201b, so that the slider 201c has a reset effect after the disc spring 201b is deformed. A sliding rod 201d is rotatably connected to the slider 201c, and the sliding rod 201d is fixedly connected to the deflection ball 106, and the two sets of sliders 201c are in the slide groove 20 The position of 1a is different, and its corresponding setting is at the clockwise end of the slide groove 1 201a, and the deflection rod 1 202e and the deflection rod 2 202f are fixedly connected to the deflection ball 106, and the deflection rod 1 202e and the deflection rod 2 202f are correspondingly fixedly connected with the folding plate 1 202c and the folding plate 2 202d, and the folding plate 1 202c and the folding plate 2 202d are inclined. Due to the inclined setting, when the drainage tube 101 is deflected by force, the deflection ball 106 on the outside of the drainage tube 101 is driven to deflect.

[0045] Working principle: When the drainage tube 101 is deflected by force, the deflection ball 106 on the outside of the drainage tube 101 is deflected. At this time, the rotating rod 1 202a and the rotating rod 2 202b on the folding plate 1 202c and the folding plate 2 202d rotate on the inner wall of the annular plate 105, and because the folding plate 1 202c and the folding plate 2 202d are inclined, the deflection angle of the drainage tube 101 has multiple directions, ensuring that the drainage tube 101 will not fall off when subjected to force. At the same time, the slider 1 201c on the sliding rod 201d slides in the slide groove 1 201a. At this time, the disc spring 201b is deformed. When the force is over, the restoring force of the disc spring 201b drives the slider 1 201c to reset, thereby ensuring the stability of the drainage tube 101 in daily use.
