1. Product use:

The positive pressure connector is in a closed state without any connecting parts connected to it, and maintains a sterile state. The male end of the connector can be arbitrarily connected to ports that require heparin caps to seal, such as peripheral veins, central veins, indwelling needles, and three-way valves. , The negative end can be connected and locked to the syringe, infusion set, blood transfusion set, complete the infusion, blood transfusion and blood drawing and other treatment tasks.

  1. Product features:
    1. When the syringe is pulled out, a positive pressure is generated, which automatically advances the liquid in the connecting tube, which can prevent blood from flowing back into the indwelling needle and avoid the formation of thrombus;
    2. Needle-free infusion to avoid needle tip injury and reduce AIDS and hepatitis infection;
    3. Closed transfusion, sufficient flow rate, equivalent to 16G needle flow rate;
    4. Sealed valve device to reduce the potential danger of air inhalation;
    5. There is no need to puncture the heparin cap with a puncture needle to prevent tiny particles from entering the infusion system;
    6. Reduce the infection and related complications of patients with indwelling venous needles and catheters, and reduce the workload of nursing staff.
  2. Applicable departments: ICU, NICU, tumor chemotherapy, family ward, operating room, general ward, etc.
  3. Applicable connecting tubes: venous indwelling needle, PICC, central venous catheter, etc.
  4. Applicable people:
    1. Long-term infusion therapy for patients;
    2. The elderly, children and patients with restricted water input;
    3. Cancer patients and those with poor vascular conditions;
    4. Rescue patients during surgery and critically;
    5. Those with impaired coagulation mechanism;
    6. People with blood and peritoneal dialysis.
  5. Clinical advantages:
    â… Protect medical staff
    1. No need to use needles to avoid medical staff being injured by needles;
    2. Disinfection is simple and convenient. The positive pressure connector does not need to use anticoagulant to seal the tube after removing the infusion set, which reduces the inconvenience to medical staff caused by multiple blood draws;
    3. The multi-channel function of the positive pressure connector can reduce multiple blood draws and multiple injections, which brings convenience to the work of nursing staff;
    4. The probability of clogging of the positive pressure connector is zero, while reducing the workload of needle puncture and repeated puncture.

â…¡Protect the patient
1. Reduce the probability of infection, reduce the complications of using indwelling needles, and reduce the pain caused by repeated needle sticks and multiple blood draws to prevent the indwelling needle from clogging;
2. The positive pressure connector has almost no dead space, and the residual volume is only 0.06ML, which can avoid the waste of expensive drugs and ensure the accuracy of the dose;
3. In the process of blood transfusion, the positive pressure connector can avoid the damage of red blood cells and reduce the blood transfusion reaction;
4. When the patient goes out or has agitation, the positive pressure connector can be temporarily separated from the infusion set, and then connected later to prevent the infusion set from getting entangled or falling off;
5. The positive pressure connector does not need to use anticoagulant, only need to be washed with physiological saline, so the patients with problems with anticoagulant mechanism play a protective role;
6. Positive pressure connector is not a disposable product, it is safe, convenient and economical for patients who need intravenous infusion for a long time;
7. Positive pressure connector can provide sufficient flow, which is of great significance to some special patients;
8. The positive pressure connector uses a screw connection, which saves scalp needles, heparin caps, saline, sodium heparin, needles, gauze, and syringes required for tube sealing and special medical solutions, reducing the financial burden for patients.

  1. Operation method:
    1. Strictly follow the aseptic operation regulations;
    2. Check the package, remove the positive pressure connector after opening, use a needleless connector syringe to extract 2-3ML of saline, connect it to the negative end of the positive pressure connector, and make the positive end of the connector vent upward;
    3. Remove the protective cap of the positive pressure connector and use its male end with the punctured indwelling needle;
    4. Pump back with a syringe to expel the air between the indwelling needle and the positive pressure connector;
    5. At this time, the infusion set is immediately connected, and the infusion set can be connected to the positive pressure connector immediately to perform the infusion.
    6. After the infusion, the positive pressure joint is injected with an appropriate amount of physiological saline to rinse the remaining liquid;
    7. The replacement of the positive pressure connector is generally based on the replacement period of the indwelling needle, and its disposal method can be handled according to the regulations of the hospitals in various regions.
  2. Matters needing attention:
    1. When the infusion set is connected to the negative end of the positive pressure connector, the gas in the infusion tube must be drained to ensure that there is no gas in the infusion tube;
    2. When the syringe or infusion set is unplugged, do not clamp the connecting tube with hemostatic forceps or switch to avoid affecting the positive pressure;
    3. Remember not to pierce the negative end of the positive pressure connector with a needle.
