Description

Technical Field

[0001] The utility model belongs to the technical field of medical auxiliary equipment, and particularly relates to a warning and fixing device for thoracic drainage tubes. Background Technique

[0002] Thoracic drainage is a drainage method in which a special silicone tube, plastic tube, surgical thoracic drainage tube, etc. are inserted into the thoracic cavity, and the gas, pus, blood, etc. in the thoracic cavity are continuously discharged. In the medical field, when there is gas accumulation and fluid accumulation in the thoracic cavity of a patient, closed thoracic drainage is usually required.

[0003] The drainage tube used for thoracic drainage needs to be in the patient's body for a period of time. It can only be removed after the drainage volume is reduced to the standard. During the period when the drainage tube is placed in the patient's body, the care of the thoracic opening should be done well. In hospitals, dressing is mostly used for care. The following deficiencies exist in the existing use of dressings for care: after applying the dressing, some patients will scratch unconsciously, causing the dressing to fall off. After the dressing falls off, medical staff cannot find it in time, which is likely to cause infection at the patient's wound. Content of the Utility Model

[0004] In order to solve the above technical problems, the utility model provides a warning and fixing device for thoracic drainage tubes. By setting a temperature sensor to monitor whether the dressing falls off, it can give an alarm in time when the dressing falls off, so as to play a warning role in preventing patient infection. The technical solutions adopted are as follows:

[0005] A warning and fixing device for thoracic drainage tubes includes a drainage tube inserted into the patient's thoracic cavity. A dressing is applied at the position where the drainage tube is inserted outside the patient. Temperature sensors are provided at the four inner corners of the dressing. The temperature sensors are connected to an alarm through connecting wires, and the alarm is tied to the outside of the drainage tube through a fixing tape.

[0006] Further, the connection between the connecting wire and the alarm is a movable connection. A connection hole is provided on one side of the alarm, and a connection plug inserted into the connection hole is provided at one end of the connecting wire.

[0007] Further, the temperature sensor adopts a patch type temperature sensor, which is small in size and has no discomfort when attached to the patient's skin.

[0008] Further, a fixing film for fixing the rear section of the connecting wire is adhered above the dressing, and a medical bandage for wrapping the front section of the connecting wire is wound around the outside of the drainage tube.

[0009] Furthermore, a control board is provided inside the alarm. The control board is powered by a button battery and has a single-chip microcomputer as the processor. The control board receives the electrical signals from the temperature sensors and identifies the temperatures detected by the temperature sensors at each position. When the dressing falls off, one or more temperature sensors will surely fail to detect the patient's body temperature. At this time, the alarm sounds an alarm through the buzzer installed in the control board to remind the medical staff to process it in time.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] When the dressing is attached to the patient's skin, the utility model can detect the patient's body temperature through the temperature sensors. When a corner of the dressing falls off or the dressing falls off completely, one or more temperature sensors will surely fail to detect the patient's body temperature. Thus, the controller can control the buzzer to sound an alarm to remind the medical staff to process it in time, achieving a warning effect.

[0012] In the utility model, both the fixing film and the medical bandage are used to arrange and fix the connecting wires, which can prevent the messy connecting wires from being accidentally pulled by the patient and affecting the normal use of the warning device.

[0013] In the utility model, alarm values for too low and too high temperatures can be written into the single-chip microcomputer in the control board. While reminding of the dressing falling off, it can also remind the medical staff that the patient has a fever symptom when the patient's body temperature rises, increasing the scope of application and improving the utilization rate.

[0020] To enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] As shown in the attached Figures 1-4 figure.

[0022] A warning fixing device for a thoracic drainage tube, comprising a drainage tube 1 inserted into the patient's thoracic cavity. At the position where the drainage tube 1 is inserted outside the patient, a dressing 2 is applied. Temperature sensors 5 are provided at the four corners inside the dressing 2. The temperature sensors 5 are patch-type temperature sensors, which are small in size and cause no discomfort when attached to the patient's skin.

[0023] The temperature sensors 5 are connected to an alarm 3 through connecting wires 4. The alarm 3 is tied to the outside of the drainage tube 1 through a fixing tape 7. The connection between the connecting wire 4 and the alarm 3 is a movable plug-in connection. A connection hole 32 is provided on one side of the alarm 3, and a connection plug 41 for inserting into the connection hole 32 is provided at one end of the connecting wire 4.

[0024] To fix the connecting wire 4, a fixing film 6 is provided above the dressing 2, and a medical bandage 8 for wrapping the connecting wire 4 is wound around the outside of the drainage tube 1.

[0025] The temperature sensors 5 in the present utility model are purchased on the market. Their installation method, connection method or setting method are all common methods and are connected to the control board 31 in the alarm. The control board 31 uses a single-chip microcomputer as the processor inside. The working principle is as follows: The temperature of the four temperature sensors 5 is monitored in real time by the single-chip microcomputer. When the temperature sensors 5 are in contact with the patient's skin, the measured temperature range should be 30 - 37. Since the temperature sensors 5 are placed in the sticky area at the edge of the dressing 2, when the dressing 2 falls off, one or more temperature sensors 5 will also be separated from the patient's skin. An alarm value, such as 20 degrees, can be written into the single-chip microcomputer. After the temperature sensors 5 are not in contact with the patient's skin, the temperature values detected by the temperature sensors 5 will drop rapidly. When the temperature is lower than the alarm value of 20 degrees, the single-chip microcomputer controls the buzzer to give an alarm. An alarm value for too high temperature, such as 37.5 degrees, can also be further written into the single-chip microcomputer. When the temperature sensors 5 detect that the patient's body temperature rises and exceeds this alarm value, the single-chip microcomputer can also control the buzzer to give an alarm to remind the medical staff that the patient has a fever symptom. Further, to facilitate the medical staff to distinguish whether it is an alarm for the dressing 2 falling off or an alarm for the patient's body temperature being too high, the two can use different buzzer alarm sounds for distinction.

[0026] When medical staff perform the operation of removing the dressing 2, they can first turn off the alarm 3 through the switch outside the alarm 3, pull out the connecting plug 41 from one side of the alarm 3, then remove the fixing film 6 from above the dressing 2, remove the dressing 2, and finally remove the temperature sensor 5 adhered to the inner side of the dressing 2; when the dressing 2 is in use, a circular hole is cut in the center of the dressing 2 and then cut along one side of the circular hole so that it can be sleeved on the outside of the drainage tube 1. Therefore, when the dressing 2 is replaced, the settings of the alarm 3, the connecting wire 4, and the temperature sensor 5 will not be affected.

[0027] When replacing the new dressing 2, the opposite operation is adopted. After the dressing 2 is sleeved on the outside of the drainage tube 1, first stick the temperature sensor 5 on the inner side of the dressing 2, then paste the dressing 2 in place, tidy up the connecting wire 4, and tie it above the dressing 2 through the fixing film 6 to prevent the patient from inadvertently pulling the connecting wire 4 and affecting the normal use of the warning device. Finally, insert one end of the connecting plug 41 into the alarm 3 and start the alarm 3 through the switch outside the alarm 3.

[0028] To ensure the normal use of the drainage tube 1, when fixing the alarm 3 with the fixing tape 7, only ensure that the alarm 3 does not fall off, and do not wind it tightly to prevent the drainage tube 1 from deforming.

[0029] Any technical solution using the technical solution of the present invention or designed by those skilled in the art under the inspiration of the technical solution of the present invention and achieving the above technical effects falls within the protection scope of the present invention.
