4.Particle filtering half mask need to be inspected prior to each use to assure there are no holes in the breathing zone other than punctures around and staples and no damaged has occurred. Enlarged holes resulting from ripped or torn filter material around staple punctures are considered damage.

5.Thisparticle filtering half mask helps protect against certain particulate contaminants but does not eliminate exposure to the risk of contracting disease or infection. Misuse may result in sickness or death.

6.This particle filtering half mask marked “NR”, shall not be used for more than one shift.

Fitting Instruction

1.Open the particle filtering half mask, face to the inside of the mask, and hold the mask on each hand so that the nose clip is at the top.

2.Take out the retaining clip from the package and fasten one end of the retaining clip to one side of the mask.

3. Hold the particle filtering half mask in position over the nose and mouth, and fasten the other end of the retaining clip to the other side of the mask.

4. Adjust to a comfortable position and make the mask fit the face.

5. Bend the nose clip to make a tight seal around the nose.


  a)To test the fit of the particle filtering half mask, cup both hands over the particle filtering half mask and inhale sharply. If air flow is felt in the nose area, re-adjust/tighten the nose clip.

  b)If flows is felt around the edges of the particle filtering half mask, re-position the mask harness to achieve a better fit.

7.Change the particle filtering half mask immediately if breathing becomes difficult or particle filtering half mask becomes damaged or distorted.

8.Change the particle filtering half mask if a proper face seal cannot be achieved.

9.Careful observances of these instructions is an important step in safe particle filtering half mask use.

Intended use:

It is suitable for adults and adolescents in the dilation operation of digestive tract stricture under endoscopes.


  • The balloon can be gradually increased at three distinct diameters under specific pressure, providing much more choice for physicians.
  • Elastic soft tip design, which can smoothly enter into the target position with less damage.
  • Rapid drainage design helps to reduce surgery time.
  • Use imported material with high pressure resistance and safer dilation.
  • Thermostatic shaping after multi-wing pleating contributes to excellent resilience and flexible retreat from working channel.
  • Optimal design of the tube makes it smooth and of good elasticity, strong twisting resistance and easier passability.
  • The radiopaque markers on the both ends of the balloon can provide precise positioning under X-ray.
  • Pre-input 0.035” guide wire with soft tip and mark, which is easier to estimate the length of the inside guide wire.

Intended use:

It is used for the expansion and treatment of esophagus and cardia.


  • Made by medical polymer materials with proper softness.
  • Anti-shedding design, more safety and reliable.
  • The front cone angle is manufactured by mechanized processing. With smooth transition, it can be inserted into the narrow parts successfully.
  • Two radiopaque marks on both ends make it easy to observe under X-ray.
  • Print scales on both sides, allowing the physicians to identify the insertion length.

Intended use:

This device is mainly used to remove bile duct stones or foreign bodies in upper and lower digestive tract.


  • With injection port in handle, it is convenient to inject contrast medium smoothly.
  • Excellent delivery performance makes it easier to reach the target.
  • Push-pull handle together with rotatable design makes stone grabbing more easy and effective.
  • Diamond shape basket is easily to grab and release, especially for repeat use.
  • Memory alloy design of basket ensures that it can remain original shape after sophisticated stone removal.
  • Three different types of basket are available to meet clinical requirements, including diamond, spiral and oval shape.
