Wherein, Gauze, gauze pad or the gauze ball of described gauze for making with woven cloths or non-woven fabrics.

For achieving the above object, the present invention also provides a kind of production method of safe medical operating gauze, in the production of gauze finished product, will outside human body, be detected the detection body that instrument senses sew up, bonding, inweave gauze body surface or nexine, or directly be coated on gauze body nexine.

For achieving the above object, the present invention also provides a kind of detection system that is used to survey gauze in the human body, it is characterized in that: comprise the gauze body, survey body and survey meter, described detection body is attached to the surface or the inside of gauze body, described survey meter comprises transmitter/receiver unit, processing unit and alarm unit, the electromagnetic wave of the transmitter/receiver unit emission setpoint frequency of described survey meter, described detection body is used to respond electromagnetic wave, and inverse signal, the transmitter/receiver unit of described survey meter receives inverse signal, outputs control signals to alarm unit after treated unit judges is correct and reports to the police.

The invention has the beneficial effects as follows: the present invention by on the gauze body, sew up, bonding, inweave or coat one and survey body, this detection body can be arrived by external survey meter.When with the close detection of survey meter body certain distance, survey meter can contactlessly detect the detection body, sounds or the light warning, with the prompting medical worker, the gauze of leaving over is arranged in the patient body.Because of this survey meter is a kind of light instrument, can survey by handing, so can finish the back, survey before the myometrial suture in patient operation, the instant discovery, the instant processing, cause after having avoided sewing up malpractice and again incision cause patient's misery.

Feature of the present invention and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.

[description of drawings]

Fig. 1 is the product sketch map of the embodiment of the invention one.

[specific embodiment]

As shown in Figure 1, the medical operation gauze of present embodiment comprises gauze body 2 and is positioned at the detection body 1 of gauze body 2 surfaces or the inside, surveys body 1 and comprises shell and be sealed in the intravital body core of shell.The body core can be induction substance metal, chip, magnetic material etc., and the body core is preferably passive type RF identification coil or RF identification chip (being the RFID chip, Radio FrequencyIdentification) in the present embodiment.REID is a kind of emerging automatic identification technology, and along with the maturation of large scale integrated circuit technology, the volume of RF identification chip dwindles greatly, makes REID enter the stage of practicability, becomes a kind of sophisticated automatic identification technology.REID is to utilize RF-wise to carry out the noncontact two-way communication, to reach identifying purpose and swap data.Gauze detection system of the present invention comprises attached to the detection body that includes RF identification coil or RF identification chip and survey meter two parts on the gauze.RF identification chip is that several main modular are integrated in the chip piece, finishes and the communicating by letter of survey meter.There is EEPROM to be used for store identification sign indicating number or other data on the chip.The EEPROM capacity from several bits to several ten thousand bits.Chip periphery only need connect antenna.For further reducing volume, RF identification chip adopts passive type, do not need battery in the chip, utilize the electromagnetic wave of survey meter emission that energy is provided, in light weight, volume is little, the life-span is long, low price, but its transmitting range is restricted, generally is tens centimetres, the maximum distance that noncontact is surveyed in the present embodiment is 35 centimetres, and needs the transmitting power of survey meter big.The advantage that the RF identification coil is compared RF identification chip is simple in structure, and volume is little.
