Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a medical negative pressure suction device. Background Art

[0002] Medical negative pressure suction devices are generally used to remove bleeding, exudate, pus, and contents of chest organs during surgery, making the surgery clear and reducing the chance of contamination. Due to the development of the field of neurointervention, in medical interventional surgery, in the process of treating intracranial thrombosis, medical negative pressure suction devices are used to provide a certain negative pressure to help doctors aspirate thrombi.

[0003] At present, the existing medical negative pressure suction device, during use, does not have an alarm function, resulting in the inability to replace the suction container in time when the medical negative pressure suction device is full, affecting the normal drainage work. Medical staff are required to check whether the medical negative pressure suction device is full regularly, which greatly increases the workload of medical staff. For this reason, we propose a medical negative pressure suction device. Utility Model Content

[0004] The purpose of the utility model is to provide a medical negative pressure suction device to solve the existing problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a medical negative pressure suction device, comprising a collecting bag, a telescopic rod and a floating plate, the top of the collecting bag is sealed and connected with a top cover, a column is fixedly installed at the top center position of the top cover, an alarm is provided on the top of the column, a cavity is provided inside the column, a first circuit-breaking wire is provided at the bottom of the alarm, a first contact head is provided at the bottom end of the first circuit-breaking wire, the first contact head extends to the inner top wall of the cavity, a telescopic rod is slidably connected to the inside of the cavity, the bottom of the telescopic rod extends to the inner top of the collecting bag, a floating plate is fixedly installed on the bottom of the telescopic rod, a first conductive plate is fixedly installed on the top of the telescopic rod by inlaying, and the top A micro negative pressure pump is provided on one side of the top of the cover, and the bottom air inlet of the micro negative pressure pump extends to the inner top of the collection bag, and a second circuit-breaking wire is provided on one side of the outside of the micro negative pressure pump, and the end of the second circuit-breaking wire passes through the column and extends to the inside of a limiting groove on one side of the interior of the cavity, and the end of the second circuit-breaking wire is connected to a second contact head, and the second contact head is arranged on the inner wall surface of the limiting groove, and limiting grooves are provided on the inner wall surfaces on both sides of the cavity, and limiting blocks are fixedly arranged on both sides of the top of the telescopic rod, and the limiting blocks extend to the inside of the limiting groove and are slidably connected thereto, and a second conductive plate is provided on the surface of one end of the limiting block close to the second contact head by inlaying, and the second conductive plate is in close contact with the second contact head.

[0006] During use, the internal liquid level of the collection bag rises. When the liquid level reaches the internal top of the collection bag, the floating plate causes the telescopic rod to rise with the increase of the liquid level. Finally, the top of the telescopic rod contacts the internal top wall of the cavity, so that the top of the first conductive plate contacts the two first contact heads. Under the action of the first conductive plate, the two first contact heads form a passage, so that the alarm is energized, and the alarm device is controlled by the alarm to sound an alarm to remind medical staff that the collection bag is full, so that the medical staff can replace the collection bag in time. By arranging a second disconnecting wire on one side of the micro-negative pressure pump and arranging a second conductive plate on one side of one of the limit blocks, the micro-negative pressure pump can work stably when the liquid level reaches the height of the floating plate. When the liquid level continues to rise after reaching the height of the floating plate, the second conductive plate is driven to move upward by the telescopic rod, so that the second conductive plate is separated from the contact with the two second contact heads, so that the micro-negative pressure pump stops powering and working. The telescopic rod is limited by the provided limit groove and limit block to prevent the telescopic rod from being separated from the cavity, resulting in the telescopic rod being unable to rise with the first conductive plate.

[0007] Preferably, speakers are provided on both sides of the exterior of the alarm, and the speakers are fixedly mounted on both sides of the exterior of the alarm by means of inlaying.

[0008] A voice alarm is provided through a speaker to remind medical staff to dispose of the collection bag in time.

[0009] Preferably, an alarm light is provided on the top of the alarm, and the alarm light is fixed to the top of the alarm by mounting screws.

[0010] The optical alarm is realized by the alarm light, and the loudspeaker is used to improve the alarm effect, reminding medical staff to deal with the collection bag in time.

[0011] Preferably, the collecting bag is a conical structure, and scale lines are provided on one side surface of the outside of the collecting bag.

[0012] By designing the collection bag into a conical structure and setting scale lines on its outside, the measurement accuracy of milliliters can be improved to a certain extent compared with the traditional columnar structure collection bag.

[0013] Preferably, a drainage interface is provided on the side of the top of the top cover away from the micro negative pressure pump, and the bottom end of the drainage interface is connected to the inner top end of the collection bag.

[0014] The drainage tube is connected through the provided drainage interface so that the drainage liquid can be guided to the interior of the collection bag for centralized collection and treatment.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. By using the floating plate to drive the telescopic rod to rise, the first conductive plate on the top of the telescopic rod can form a path for the first contact heads at the ends of the two first broken wires, thereby energizing the alarm, activating the alarm, and using the speaker and alarm light to sound an alarm so that medical staff can handle it as soon as possible. With this design, wireless medical staff repeatedly check whether the collection bag is full, which reduces the workload of medical staff.

[0017] 2. By setting a second disconnecting wire on one side of the micro negative pressure pump and setting a second contact head at its end, the limit block is used to drive the second conductive plate to rise and fall, so as to control the on and off of the power supply of the micro negative pressure pump. When the collection bag is full, the telescopic rod rises, driving the second conductive plate to rise, thereby disconnecting the power supply of the micro negative pressure pump, avoiding the micro negative pressure pump from continuing to work during the alarm process, resulting in liquid overflow.
