Abstract

The utility model relates to a medical instrument, in particular to an anesthesia control instrument designed aiming at the intravenous administration of stupefacients in an anesthesia room and an operation room. A control board of the anesthesia control instrument is connected with a motor, a detection unit of a needle cylinder, an adaption board, a display, a keyboard, a switching power supply and the electric input of a network; and the adaption board is externally connected with an RS232 interface and an injection detection unit. Compared with the prior art, the anesthesia control instrument disclosed by the utility model has the advantages that the difference of the actual concentration of a plasma medicine and a predicted value can be reduced, and the aim of carrying out administration according to the concentration of the plasma medicine or the concentration of an effect compartment automatically can be realized. The anesthesia control instrument has the action of automatically calculating the total quantity of injection, has the function of adding the loading dose and has the capabilities of using and identifying injectors with different sizes.

Description

The anesthesia controller

Technical field

This utility model relates to Medical Instruments, particularly a kind of anesthesia controller that designs to narcotics intravenously administrable in anesthetic room and the operating room.

Background technology

At present, anesthesia is mainly manually-operated, receives the restriction of anaesthetist's experience level, and narcotic dosage is difficult to accurate control.

The utility model content

The purpose of this utility model is to provide a kind of anesthesia controller of realizing accurate loading.

The purpose of this utility model realizes through following approach: a kind of anesthesia controller, panel connect motor, syringe detecting unit, keyset, display, keyboard, Switching Power Supply and the input of net electricity; The external RS232 interface of keyset, injection detection unit;

Described syringe detecting unit is to be made up of with the loading bucket clip of placing syringe three photoelectric sensors that are communicated with panel, and three photoelectric sensors place respectively and load bucket clip Different Diameter depths;

Described injection detection unit be by one through keyset be communicated with the photoelectric sensor of panel, the test rod that is connected with the syringe propeller constitutes, photoelectric sensor is installed on the path that test rod moves forward and backward.

Further, described panel master chip model is LPC2478.

Further, described panel connects buzzer.

Compared with prior art there is following advantage in this utility model anesthesia controller:

During 1) to the administration of compatriots' target controlled infusion, reduced the difference of actual plasma drug level and predicted value;

2) intravenously administrable of configuration international most advanced level is injected system, and system presses plasma drug level or the administration of effect compartment concentration automatically;

3) calculate the injection total amount automatically, append the loading dose function;

4) multiple concentration, body weight, unit of time convert;

5) possess and use and the ability of discerning different big or small syringes;

6) intelligent alarm system.

Description of drawings

Below in conjunction with accompanying drawing this utility model is done further explain:

Fig. 1 is this utility model structural representation;

Fig. 2 is the structural representation of this utility model syringe detecting unit 3;

Fig. 3 is the structural representation of this utility model injection detection unit 7;

Among the figure, panel 1, motor 2, syringe detecting unit 3, buzzer 4, keyset 5, RS232 interface 6, injection detection unit 7, display 8, keyboard 9, Switching Power Supply 10, net electricity input 11, photoelectric sensor 13, a loading bucket clip 14, test rod 15, syringe propeller 16.

The specific embodiment

As shown in Figure 1, this utility model anesthesia controller, its panel 1 connect motor 2, syringe detecting unit 3, keyset 5, display 8, keyboard 9, Switching Power Supply 10 and net electricity input 11; The external RS232 interface of keyset 56, injection detection unit 7; Described panel 1 master chip model is LPC2478.Described panel 1 connects buzzer 4.

As shown in Figure 2, described syringe detecting unit 3 is to be made up of three photoelectric sensors that are communicated with panel 1 13 and the loading bucket clip 14 of placing syringe, and three photoelectric sensors 13 place respectively and load bucket clip 14 Different Diameter depths; Its operation principle: photoelectric sensor 13 utilizes detected material to the blocking or reflect of light beam, and by the synchronization loop gating circuit, thereby inspected object has or not.When not having syringe, three photoelectric sensors 13 are not blocked, and when being small size syringe, are blocked from loading the nearest photoelectric sensor 13 in bucket clip 14 centers; When being the medium size syringe, blocked with nearly slightly two photoelectric sensors 13 recently from loading bucket clip 14 centers; When being the large size syringe, three photoelectric sensors 13 are all blocked, thereby realize the detection to the syringe size.

As shown in Figure 3, described injection detection unit 7 be by one through keyset 5 be communicated with the photoelectric sensor 13 of panels 1, the test rod 15 that is connected with syringe propeller 16 constitutes, photoelectric sensor 13 is installed on the path that test rod 15 moves forward and backward.Syringe propeller 16 advances syringe to inject toward the direction of motion; When near emptying the time; Whether the test rod 15 that is connected with syringe propeller 16 can block photoelectric sensor 13, at this moment can judge syringe emptying through detecting photoelectric sensor 13, thereby stop injection.

The work process of this utility model anesthesia controller is following: Switching Power Supply 10 makes the instrument start through pressing " opening " button, and follows very brief sound 2, and instrument confirms that through System self-test hardware and software feature is normal.All light emitting diodes (LED) are luminous in the self check process, if this instrument uses with battery operation, then AC LED is not luminous.Pinning " pass " key button instrument closes applied power source.More than show will appear in the whole power-off process, after the electric power shutdown sequence finishes, the screen blackening.If this instrument power source plug still is inserted on the AC supply power supply, AC LED can be still luminous, internal battery charging this moment.Display is connected with master control borad, is mainly used in to show various man machine interfaces the raising operability.The human-machine operation interface of software has the selection quantity function of recommending the syringe brand.Each syringe brand selects the page can show original syringe brand, confirms to select the back to show new needle selection tube brand.Each its injection error of specification syringe of all recommended brands is less than 1%.RS232 interface 6 links to each other with panel 1 through keyset 5, and panel 1 can pass through data such as RS232 interface 6 outside transmission rates, injection volume, also can receive external command through RS232 interface 6.The communications protocol of the compatible Graseby 3500 of this communications protocol.Buzzer 4 with directly link to each other with panel 1, mainly realize various warnings.Warning is divided into two types: failure classes, prompting class.Failure classes are used visual, the audible alarm of 1Hz, " ticking " audible alarm of prompting type use 0.1Hz and suitable visual alarm.This utility model is reserved TCI software module interface in addition, has improved " aimed concn " input pattern under the TCI pattern.When the input aimed concn, show " drug level in the syringe ", " operation concentration " recommended range value, " analgesia or calm " recommended range value of this medicine simultaneously, numerical value input place display highlighting.
