Brief summary
The purpose of this study is to explore the clinical effect of disposable tissue suction tube set for induced abortion and make comparison with traditional metal instruments．
Interventions
PROCEDUREthe disposable tissue suction set
Induced abortion is a main backstop for terminating unwanted pregnancies, however, traditional hard metal instruments has lots of insufficiencies such as easily tissue damage, and repeatedly sterilization increases the incidence of cross infection in the hospital what leads to more complications of pelvic inflammation, infertility and so on. Therefore disposable non-metallic instruments are desperately needed as a way to decrease the complications and provide better medical services to patients. So, the investigators want to explore the clinical effect of disposable tissue suction tube set and make comparison with traditional metal instruments.
PROCEDUREtraditional metal instruments of abortion
Induced abortion is a main backstop for terminating unwanted pregnancies. In Chinese hospital, traditional metal instruments are always used during the surgery. So the investigators want to explore the clinical effect of disposable tissue suction tube set and make comparison with traditional metal instruments.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| blood loss (ml) | up to 5-10 minutes | It always takes 5-10 minutes to finish the induced abortion in the outpatient, so the investigators will measure the blood loss during the operation time. |
| the rate of induced abortion syndrome (%); | up to 5-10 minutes | It always takes 5-10 minutes to finish the induced abortion in the outpatient, so the investigators will observe whether induced abortion syndrome happens to our patients during the operation time. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| evaluate pain grade (0, I, II, III) by questionnaire | up to 5-10 minutes | The participants will be asked some questions on questionnaire about feeling to evaluate their pain grade. |
| rate of leaving bed in 5 min by patient self (%) | 5 min after the surgery | — |
| operation time (minutes) | up to 5-10 minutes until the operation finished | measure the operation time |
| the success rate of induced abortion (%) | up to 15 days after the surgery | Ultrasound and gynecological examinations will be used to calculate the success rate of induced abortion. |
