Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a cerebrospinal fluid leakage regulating pillow. Background Art

[0002] Cerebrospinal fluid flows into the nasal cavity through congenital or traumatic bone defects, ruptures or thinning at the bottom of the anterior cranial fossa, the bottom of the middle cranial fossa or other parts, which is called cerebrospinal fluid rhinorrhea. Among various types of cerebrospinal fluid rhinorrhea, trauma is the most common. Cerebrospinal fluid otorrhea is often caused by middle cranial fossa fracture involving the tympanic cavity. Fracture of the middle cranial fossa causes the meninges above the middle ear to be torn, and the tympanic membrane to rupture, which can cause cerebrospinal fluid to leak out of the external auditory canal to form cerebrospinal fluid otorrhea.

[0003] Patients with cerebrospinal fluid leakage usually need to rest in a supine position, and the course of the disease is long, up to several months, so their nursing work is particularly important. In clinical practice, for the care of patients with cerebrospinal fluid leakage, no packing and no flushing measures should be taken, and the patient's sleeping posture and head height should be constantly adjusted according to the situation of cerebrospinal fluid leakage. Among patients with cerebrospinal fluid leakage, a certain proportion of patients are in a coma. When cerebrospinal fluid overflows, they are usually unable to take the initiative or inform their family members and medical workers for further treatment. During insomnia at night, cerebrospinal fluid overflow is not easy to be discovered in time. Based on the above, it is necessary to develop a cerebrospinal fluid leakage alarm smart pillow that is easy to adjust the patient's head height and posture, and is used to detect cerebrospinal fluid leakage in time, to provide high-quality care for patients with cerebrospinal fluid leakage, and to reduce the burden on their families and medical workers.

[0029] like Figures 1 to 3 As shown, a cerebrospinal fluid leakage regulating pillow includes a pillow 1, a detection device, an inflation device and an alarm device; wherein:

[0030] Side air pillows 2 are arranged on both sides of the pillow 1. The inflated side air pillows 2 can lift one side of the patient's head. A neck air pillow 3 is arranged on the back side of the middle part of the pillow 1. The inflated neck air pillow 3 can lift the back of the patient's neck upwards, thereby lifting the patient's head backwards.

[0031] The detection device is installed on both nose sides and both ear sides and is used to detect the location where cerebrospinal fluid leakage occurs.

[0032] The inflation device is used to inflate and deflate the air pillows 2 on both sides or the cervical air pillow 3 according to the location of cerebrospinal fluid leakage, so as to raise the patient's head to avoid cerebrospinal fluid leakage.

[0033] The alarm device is used to send information about the location where cerebrospinal fluid leakage is detected and issue an alarm, so as to promptly remind the patient's family members or medical staff to provide corresponding care.

[0034] The detection device, the inflation device and the alarm device are all electrically connected to a main controller, and the main controller receives the signal from the detection device and controls the inflation device and the alarm device to perform corresponding actions.

[0035] like Figure 2 , 3 As shown, the middle part of the pillow 1 comprises a cotton pad layer 11, a rubber layer 12 and an elastic net 13 from bottom to top; the rubber layer 12 has a waterproof effect and is used to protect the cotton pad layer 11 to prevent cerebrospinal fluid from soaking the cotton pad layer 11; the elastic net 13 is made of a dense mesh and has a certain supporting strength and gaps, which can provide good support for the patient's head; the rubber layer 12 is a downwardly concave arc surface, and there is a certain gap between the rubber layer 12 and the elastic net 13, which is convenient for the patient's head to dissipate heat and ventilate.

[0036] In one embodiment, a first water immersion sensor 6 is installed on the surface of the rubber layer 12 to detect whether fluid accumulation occurs, and the first water immersion sensor 6 is electrically connected to the main controller; when water stains are detected on the surface of the rubber layer 12 of the pillow 1, family members or medical staff are required to provide immediate care, wherein the water stains may come from cerebrospinal fluid leakage of the patient or sweat accumulation and flowing into the rubber layer 12 from the elastic net 13.

[0037] In one embodiment, the detection device includes a plurality of second water immersion sensors that are electrically connected to the main controller, and the second water immersion sensors are attached to at least the two nasal sides and two ear sides of the patient; specifically, they are attached to the outer sides of the lower edges of the two nostrils and the outer sides of the lower edges of the two ears, so that when the patient lies flat and cerebrospinal fluid leaks, the cerebrospinal fluid can flow to the detection probe of the second water immersion sensor, so that the location of the cerebrospinal fluid leakage can be detected in time.

[0038] In one embodiment, absorbent cotton is provided on the detection probe of the second water immersion sensor, and the absorbent cotton is pasted near the nostrils and ear holes so that the absorbent cotton can absorb the leaked cerebrospinal fluid in time, and the leakage of cerebrospinal fluid can be detected by the detection probe of the second water immersion sensor; at the same time, the use of absorbent cotton for isolation can prevent the detection probe from being in a high humidity environment for a long time, thereby extending its service life.

[0039] Preferably, the data detected by the first water immersion sensor 6 installed on the rubber layer 12 and the second water immersion sensor of the detection device are transmitted to the main controller by wireless or wired connection.

[0040] For example, the wired water immersion sensor model can be 485 type, and the main parameters include power supply 12V-24VDC, output signal RS485 output, switch type normally open contact, detection object various types of aqueous solution, humidity accuracy ±3%RH. The wire of the water immersion sensor is directly connected to the receiving module of the main controller, which is used to receive the detection data of the water immersion sensor; wherein, the water immersion sensor and its wire can be stored in the pillow 1 for easy use.

[0041] The wirelessly connected water sensor model can be Aqara water sensor SJCGQ11LM, which is powered by CR2032 button battery, supports ZigBee wireless protocol, has a sensing distance of 22cm, and a waterproof rating of IP67; it integrates battery power supply, ultra-low power consumption, wireless communication, and leakage monitoring. When water touches the sensor (sensing cable), the loop resistance changes, triggering the water transmitter to immediately upload data to the back-end platform. The main controller is equipped with a receiving module that can be wirelessly connected to the water sensor to receive the detection data of the water sensor.

[0042] In one embodiment, the inflation device includes an inflation pump with inflation and deflation functions, and the inflation pump is connected to the air pillows 2 and the neck air pillow 3 on both sides through pipes respectively, and each pipe is provided with an electrically controlled valve, or each pipe is connected to an electrically controlled three-way valve, and the corresponding passage is opened according to the inflation or deflation required by the air pillows 2 and the neck air pillow 3 on both sides.

[0043] Specifically, when the second water immersion sensor detects cerebrospinal fluid rhinorrhea, the main controller controls the air pump to start and inflate the neck air pillow 3 to lift the back of the patient's neck upward to raise the patient's head back; when the second water immersion sensor detects cerebrospinal fluid otorrhea on one side, the main controller controls the air pump to start and inflate the side air pillow 2 on the corresponding side to lift the patient's head on one side.

[0044] In one embodiment, the alarm device includes a buzzer 4. When the main controller receives a signal from the detection device (including the water immersion sensor on the rubber layer 12) that cerebrospinal fluid leakage is detected, the main controller controls the buzzer 4 to sound a buzzer to alert family members or medical staff.

[0045] In another embodiment, the alarm device further includes a communication module for wireless communication with the nurse station, and transmits the cerebrospinal fluid leakage to the nurse station through the communication module. For example, the communication module can be wirelessly connected to some smart ward systems, so that each detection data can be transmitted to the nurse station or mobile device through the wireless network, thereby realizing remote monitoring and timely response; the detection data received on the nurse station or mobile device will indicate the specific location of the cerebrospinal fluid leakage and issue a pop-up reminder.

[0046] like Figure 1 As shown, the pillow 1 is provided with a power supply and a charging interface 5, and the power supply is used to power the inflation pump, the main controller, the wired water immersion sensor and the alarm device; the inflation device, the buzzer 4 and the power supply are all built into the pillow 1, and a sound outlet hole for the buzzing sound to be transmitted can be opened on the pillow 1.

[0047] When in use, when the second water sensor detects leaking cerebrospinal fluid, the following occurs:

[0048] Unilateral otorrhea: Start the air pump and inflate the side air pillow 2 on the corresponding side to raise the patient's head on one side;

[0049] Bilateral otorrhea: Start the air pump and inflate the neck air pillow 3, and raise the patient's head backward; if otorrhea occurs on one side first and then on both sides, the inflated neck air pillow 3 needs to be deflated;

[0050] Rhinorrhoea: The air pump is started and the side air pillow 2 on the corresponding side is inflated to raise the patient's head on one side.

[0051] If rhinorrhea or bilateral otorrhea occurs, the cervical air pillow 3 is inflated to lift the patient's head back; if rhinorrhea or unilateral otorrhea occurs, the cervical air pillow 3 needs to be inflated, and the side air pillow 2 on the corresponding side is also inflated to control the outflow of cerebrospinal fluid.

[0052] After cerebrospinal fluid leakage occurs, the absorbent cotton needs to be replaced in time; when the first water immersion sensor 6 on the rubber layer 12 detects the presence of liquid, medical staff should provide care immediately.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present application is defined by the appended claims and their equivalents.
