Description

Technical Field

[0001] The invention relates to a medical device for drainage, in particular to a device for chest cavity capable of achieving drainage regulation, and specifically relates to an adjustable chest cavity drainage device. Background Art

[0002] Chest tube intubation and drainage may be used in a variety of situations, including spontaneous or traumatic pneumothorax resulting in > 25% lung collapse or progressively increasing pneumothorax, particularly when causing respiratory distress or severe gas exchange impairment; large or recurrent benign pleural effusions that are refractory to thoracentesis; empyema; hemothorax; malignant pleural effusions (before the use of intrapleural chemotherapy and / or sclerosing agents; in short, to drain pleural effusions); sometimes, instillation of fibrinolytic drugs into the pleural space via a chest tube can effectively treat loculated empyema, thus avoiding surgical management of septa.

[0003] The above situation shows that chest drainage devices have a wide range of applications, but current chest drainage devices mostly include drainage insertion tubes, drainage bottles or drainage needles. During use, the drainage process is mostly opened and closed based on the subjective experience of medical staff. However, there are many patients in hospitals and limited medical staff. Sometimes, untimely and inaccurate observations result in excessive drainage volume, or the drainage is forgotten to be opened after being closed.

[0004] The prior art, an intelligent chest drainage device 201810108765.5, introduces a method of counting the drainage volume through a liquid level sensor, adjusting the opening and closing of the negative pressure drainage device in a feedback manner, and reminding medical staff to adjust the flow rate control structure. Another device that can automatically control the drainage volume 201720256834.8, through a specific setting, when the drainage volume reaches a specific value, the drainage volume controller and the float actively close the drainage tube to achieve automatic adjustment.

[0005] Both of the above methods are to control the closing adjustment after reaching a specific drainage volume, but after the drainage volume reaches a specific value, the pressure in the chest cavity may not necessarily achieve the expected effect. If the opening and closing of the drainage tube can be controlled by setting the value of the intrathoracic pressure, the purpose of adjusting the chest drainage will be achieved more intuitively, the automatic adjustability will be updated, and the adjustment effect will be better.

[0006] In addition, current adjustable drainage bottles or drainage bags are often placed directly below the patient's chest without dedicated placement equipment, resulting in the risk of the drainage tube falling out due to the drainage equipment slipping during the drainage process.

[0007] The present invention aims to solve the problems in the prior art that the chest drainage process consumes a lot of labor for medical personnel or cannot be automatically adjusted through pressure well, and there is a risk of the drainage tube coming out, and provides a tissue retraction device that can be simply and conveniently inserted. Summary of the invention

[0008] In order to overcome the problems in the prior art that the chest drainage process consumes a lot of labor for medical personnel or cannot be automatically adjusted through pressure well, and there is a risk of the drainage tube coming out, the present invention provides an adjustable chest drainage device.

[0009] An adjustable chest drainage device includes a drainage tube, a drainage bottle or a drainage bag, characterized in that a drainage opening and closing control structure for controlling the opening and closing of the drainage tube is arranged on the drainage tube; the drainage opening and closing control structure includes a placement structure, a pipe for the drainage tube to pass through is arranged in the placement structure, a notch for the drainage tube to pass through is arranged on the pipe or at the front and rear ends of the pipe, a protrusion that matches the shape of the notch and can be moved into and out of the notch is arranged above or below the notch, and the protrusion is connected to an electric structure through a connecting structure; the electric structure controls the up and down movement of the protrusion, and a regulating structure for controlling the rotation direction and opening and closing of the motor is also arranged.

[0010] Furthermore, the electric structure is a stepper motor, and the stepper motor extends a rotatable threaded shaft. The protrusion is set on the threaded shaft of the stepper motor through a threaded tube sleeved on the outside of the threaded shaft, or the protrusion is set on the threaded shaft of the stepper motor through a threaded rod inserted into the inside of the threaded shaft, and a limiting structure is set on the threaded tube or the threaded rod, and a limiting structure is set in the placement structure. The limiting structure is set in the limiting structure or between the limiting structures. The purpose of preventing the limiting structure from rotating is achieved through the setting of the limiting structure, and the purpose of ensuring the upward and downward movement of the limiting structure is achieved, thereby realizing the upward and downward movement of the protrusion. When in use, the stepper motor drives the threaded shaft to rotate, and the threaded tube or threaded rod sleeved on the inside or outside of the shaft keeps moving up or down due to different directions under the limitation of the limiting structure.

[0011] Alternatively, the electric structure is an electric hydraulic structure; a telescopic rod controlled by the electric hydraulic structure is connected behind the protrusion; the effect of controlling the protrusion to move in or out is achieved through electric telescopic movement.

[0012] By setting the above structure, the rotation direction of the motor structure can be effectively controlled to achieve the purpose of controlling the protrusion to move completely into the gap to close the drainage tube, or partially move into the gap to adjust the flow rate, or move completely out of the gap for effective drainage. The whole process makes the adjustment more controllable.

[0013] Furthermore, a pressure sensor is arranged on the inner side or the outer side of the insertion end of the drainage tube, and the pressure sensor is connected to the regulating structure through a wire. The regulating structure adjusts the rotation direction of the motor and the position of the protrusion after rotation by receiving the pressure value of the pressure sensor, so as to achieve the purpose of fully opening, partially opening or fully closing the drainage tube. This method uses pressure to adjust, making the adjustment more precise.

[0014] Furthermore, an insertion structure is provided for placing a drainage bottle or a drainage bag and a drainage opening and closing control structure, and two placement slots are provided on the insertion structure, one is a low-position placement slot for placing a drainage bottle or a drainage bag, and the other is a high-position placement slot for placing a drainage opening and closing control structure. This insertion structure can well achieve the purpose of placing various structures, and can effectively prevent the occurrence of problems such as the drainage tube falling off due to the falling off of various structures during use.

[0015] Furthermore, an arc-shaped notch is provided in the middle of the pipe, and an arc-shaped protrusion is also provided. This method can achieve better matching.

[0016] Furthermore, when the electric structure is a stepper motor; a threaded tube connected to a solid threaded shaft is connected to the rear of the protrusion, a square limit block integrally connected to the threaded tube is provided at the rear of the threaded tube, or anti-rotation rods extend from both sides of the threaded tube, the limit block is provided in the limiting structure or the anti-rotation rod is inserted into the limiting structure.

[0017] Alternatively, a threaded rod is connected to the rear of the protrusion, and the threaded shaft is a tubular threaded shaft with corresponding threads inside, and the threaded rod is rotatably inserted into the threaded shaft; a square limit block connected to the threaded rod is arranged at the rear of the threaded rod, or anti-rotation rods extend from both sides of the threaded rod, and the limit block is arranged in the limiting structure or the anti-rotation rod is inserted into the limiting structure.

[0018] Furthermore, the limiting structure is two parallel plates arranged in the placement structure, and the distance between the parallel plates is equal to the width of the limiting block; or a slide groove is arranged on each parallel plate, and the anti-rotation rod is inserted into the slide groove.

[0019] Furthermore, the parallel plates extend from both sides of the stepper motor, a supporting horizontal plate is arranged in the middle of the parallel plates, a circular hole having the same size as the threaded tube or the threaded rod is arranged in the middle of the supporting horizontal plate, and a limit block or an anti-rotation rod is arranged in front of the supporting horizontal plate to prevent the supporting horizontal plate from affecting the extension and removal of the protrusion. The arrangement of the supporting horizontal plate can effectively ensure the stability of the structure.

[0020] Furthermore, the length of the slide groove is equal to the distance that the protrusion moves upward or downward.

[0021] Furthermore, the pipe is inclined upward from the bottom, and a baffle structure is arranged on the upper side of the notch corresponding to the upward movement direction of the protrusion. This arrangement facilitates the protrusion to enter the extrusion drainage tube.

[0022] Furthermore, the next placement structure of the notch is set as a cavity, and a limiting structure, a stepping motor, a protrusion, a threaded tube or a threaded rod, and a threaded shaft are set in the cavity.

[0023] Furthermore, the placement structure is divided into an upper part and a lower part, and the two parts are combined and rotated by a rotating shaft and a rotating ring connected to the two parts at the rear, and a locking structure is arranged at the front. The pipeline is divided into two parts in the placement structure, and other structures are arranged in the lower part. This structure can facilitate the arrangement of the drainage tube.

[0024] Furthermore, the locking structure is a locking protrusion structure correspondingly arranged at the upper and lower parts.

[0025] Furthermore, a pull ring for easy opening is provided on the upper part to facilitate opening.

[0026] Furthermore, the pipeline extends upward from the lower middle part of the side of the placement structure, protrusions are set on the two side surfaces corresponding to the lower part of the placement structure, and a depression is set in the high-position placement groove of the placement structure, and the protrusions and the depressions correspond to each other to achieve placement positioning.

[0027] Furthermore, a vertical plane parallel to the pipeline is arranged above the parallel direction of the pipeline, and the rotating shaft and the rotating ring are arranged on the vertical plane; this arrangement makes it more convenient to insert the drainage tube after the pipeline is bent and exposed, thereby reducing the difficulty of operation.

[0028] Furthermore, a through groove through which the drainage tube passes is arranged on the side wall of the high-position placement groove toward the low-position placement groove, and the drainage tube is placed so that it is bent and affects the drainage.

[0029] Furthermore, the wall of the low-position trough is made of transparent material. This setting can be used to facilitate the detection of drainage volume. By detecting the drainage situation from both the drainage volume and the pressure value, a better drainage effect can be achieved and some related causes of the disease can be found.

[0030] Furthermore, a base made of solid metal material is provided at the bottom of the implant structure, and the high placement slot and the low placement slot are combined with the base. This arrangement can increase the stability of the implant structure and prevent it from tilting or shaking; in addition, when the patient needs to move, the placement slot can be carried by hand for movement. Furthermore, an implantation slot is provided on the base for the implant structure combination to be placed.

[0031] Furthermore, the high-position placement slot is connected to the low-position placement slot, and a handle that can be rotated to the side is arranged on the upper side. The arrangement of the handle can greatly increase the portability of the drainage opening and closing control structure and the drainage bottle or drainage bag.

[0032] Furthermore, a wireless signal receiving and transmitting module is arranged on the control structure, and the wireless signal receiving and transmitting module is connected to the wireless signal receiving and transmitting module on the mobile terminal. The mobile terminal is used to set and detect the pressure value and control the movement of the protrusion, and the introduction of the mobile terminal can increase the convenience of observation.

[0033] Furthermore, a pipe through which the drainage tube passes is arranged in the placement structure, and anti-slip protrusions are arranged at both ends of the pipe, wherein anti-slip protrusion rings are preferably used. This arrangement can effectively prevent the drainage tube from sliding in the placement structure.

[0034] When in use, the placement structure is opened, the drainage tube is placed in the pipe, and then the placement structure is closed. The pressure value is set through the control structure, and then the drainage tube is placed in the chest cavity. The pressure is then detected through the pressure sensor. When the measured pressure value is greater than the set pressure value, the protrusion is controlled to move down to start drainage. When it is not greater than the pressure value, the protrusion is controlled to move up to close the drainage tube. The control structure can also be adjusted to set the position of the protrusion under different pressure values ​​to prevent drainage overspeed. Through the setting of the above-mentioned intelligent drainage structure, the entire drainage process is made intelligent and automated, effectively reducing the workload of medical workers.

[0035] Compared with the drainage devices in the prior art, the technical solution of the present invention is more intelligent and automated, which can effectively reduce the workload of medical staff, and can effectively and real-time understand the pressure and drainage volume in the drainage tube, making the whole process smoother and cheaper.
