Description
Technical field
The invention belongs to a kind of medical clinical monitoring device, be specifically related to a kind of digitized hospital bed monitoring network system.
Background technology
Adopt classic method often to need patient in the lesion, to carry out independent inspection by various Medical Devices to the treatment of inpatient, detect and monitoring, medical personnel put the record data and the information of various device by hand in order, it is loaded down with trivial details to detect the monitoring program, inefficiency, development along with modern medicine, more and more need medical personnel to pay close attention to patient's each details in medical procedure, immediately obtain the various physiologic informations in patient's very first time, think that patient provides high-quality clinical service, and traditional various detection meetings cause heavy physiological load to the patient, and the quality of case history also is difficult to control, diagnosis and treatment process information can be incomplete because of omission yet, influences medical personnel conditions of patients is made correct diagnosis and processing.
In recent years, along with the construction of hospital information system and perfect, many hospitals begin to set up clinic information system, but the emphasis of paying close attention to still is the doctor's advice management, subjective informations such as course of disease record, protect aspect the efficient and detect information and improve to survey in the various clinical medical technologies of obtaining the patient, as alleviate the patient detected and survey physiology and the psychological burden protect in the process, make the patient in detected and monitoring, feel aspect such as more comfortable, also exist and much need improved problem, for example 200410086483.8 disclose a kind of digitizing full ward medical information monitoring net, what its sick bed adopted is the gasbag-type mattress, and the gasbag-type mattress both had been used to support human body weight, be used to do sensor again, the moving signal of induction patient's body is because the air bag of sealing is air-locked, so it is very uncomfortable to overlie for a long time.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of not only can the raising and detects monitoring efficient, and can alleviate the patient detected and survey physiology and the psychological burden protect in the process, make the patient in detected and monitoring, feel more comfortable digitized hospital bed monitoring network system.
The technical scheme that addresses the above problem is: the present invention is provided with the computing machine lesion workstation that is connected with the hospital computer central station, the lesion workstation is connected with some local body area networks, each body area network is made up of the other workstation of sick bed unit and bed respectively, it is characterized in that: described sick bed unit is provided with elastic bed mattress (1), mattress comprises and is no less than two ventilative vertical partition pads (11,12,13,14), adjacent two subregion pads (11,12) adjacent wall (11a, 12a) draw close, heelpiece face (11b), (12b) interconnect, but the other workstation computer input end of described bed connects with the sensor output terminal of the human body physiological parameter that corresponding sick bed unit is provided with, at least comprise the body dynamic sensor (21 that places on the elastic bed mattress in the described sensor, 22), the body dynamic sensor is the sealing elastomer that is full of fluid, elastic body is equipped with the sensing element (21a that energy induction sealing cavity fluid pressure changes, 22a), the body dynamic sensor places the position that can respond to the action of human body corresponding position on the elastic bed mattress, and the other workstation of bed is provided with the monitoring display device that is connected with fanout.
Further scheme of the present invention is: the other workstation computer input end of described bed is provided with infusion module, its structure is: the snap ring (3) that is with the band opening on the transfusion drip tube outer wall of infusion set, both sides are equipped with infrared transmitting tube (D2) respectively and are received the infrared receiving tube (D1) that infrared transmitting tube transmits in the snap ring, infrared receiving tube is connected by the other workstation computer input end of sampling amplifying circuit and bed, and fanout is connected to warning circuit.
The present invention design by the central station, in the tertiary hospitals monitoring net that the other workstation of sick bed workstation and body area network bed is formed, its sick bed unit that obtains patient's raw data has adopted the ventilative subregion elastic bed mattress of belt body dynamic sensor, the patient is on elastic bed mattress, respond to human body because of heartbeat by the sensing element that is contained on the sealing elastomer of respective detection position, breathe, the moving information that waits the elastic body internal pressure variation that causes of body, this pressure change signal changes in the other computing machine of working of the collected bed of electric signal and carries out data processing, therefrom obtain patient's heart rate, parameters such as respiratory rate, and respiratory waveform, oscillograms such as each position body is moving, on the monitoring display device, show, and be transferred to the lesion workstation (also claiming nursing station) of upper level, be transferred to the central station by the lesion workstation again, network system can be gathered the multiple physiological parameter of patient immediately, monitoring, record, the subregion pad that the present invention adopts can be separated with different detection positions, the human body different parts that makes each subregion pad induction is (as chest, shank) signal is relatively independent, prevent mutual interference among signals, and, because what large tracts of land of the present invention supported human body is the elastic bed mattress of breathing freely, what induction human body body moved signal only is the sealing elastomer that is contained in the small size on the mattress, the patient can not felt well as lying in for a long time on common bed on the ventilative elastic bed mattress, alleviated measured's physiology and psychological burden greatly, digitized hospital bed monitoring network system can be continued to monitor for a long time to the patient.
The using method of the infusion set of the further scheme setting of the present invention is: snap ring (3) is enclosed within on transfusion drip tube (1) outer wall, whenever the drop of liquid of dripping, block infrared emission light once, infrared receiving tube (D1) just sends once light/fax sense signal, the other workstation computer of input bed after the sampling amplifying circuit amplifies, computing machine shows liquid droping speed on display unit, during the value range in liquid droping speed exceeds computing machine, set: as too fast, cross slow or when stopping dripping, the warning circuit of the other workstation setting of bed sends alerting signal, and the prompting paramedic regulates transfusion speed.
But the further scheme whole-process automatic monitoring of the present invention sick bed unit patient's transfusion situation, and too fast at transfusion speed, cross slow or liquid sends alerting signal when dripping off, the prompting medical personnel carry out corresponding operating, have safe, simple in structure, easy to use, save manpower, improve monitoring efficient advantage.
