elevator button

how much there is on the average elevator button?

yes, i has taken the idea of the touchless button and applied it to elevators. 

Which is a good idea if it is true: that the 3,500 is 17 times greater than the average toilet seat.

Contagion! That’s what comes from elevator buttons. Instead of the black death, try this non-contact button method.

Infusion Floating Ball (breif version)

Status: 

1. infusion pump: An infusion pump infuses fluids, medication or nutrients into a patient's circulatory system. It is generally used intravenously, although subcutaneous, arterial and epidural infusions are occasionally used.

Infusion pumps can administer fluids in ways that would be impractically expensive or unreliable if performed manually by nursing staff. For example, they can administer as little as 0.1 mL per hour injections (too small for a drip), injections every minute, injections with repeated boluses requested by the patient, up to maximum number per hour (e.g. in patient-controlled analgesia), or fluids whose volumes vary by the time of day.

2. infusion alarming device: The present invention relates to a liquid level detector and alarm device for installation in the bottle of a drip infusion set to detect the liquid level, and to give an audio alarm when the liquid level drops below a predetermined value.

When a drip infusion set is used for the introduction of a saline or other solution into a vein to treat the patient, the nurse must frequently review the liquid level of the solution so that the infusion can be stopped before the solution is fully consumed. In case the infusion is not stopped when the solution is fully consumed, a reverse flow of blood or the introduction of air into the vein may occur. There are known various monitoring apparatus for automatically monitoring drip infusion. These monitoring apparatus give an audio alarm signal when detect no drips of solution within a predetermined length of time. However, these monitoring apparatus are commonly heavy and expensive.

Why I made this device?

• release patients’ pressure

• Reduce nurses’ workload 

What is it ? 

Two hollow balls are put separately in the fluid bag and Murphy’s dropper, one is for reminding the volume and the other is for ceasing the infusion when the infusion liquid is nearly finished.

6.Flow control cap

Ball (in fluid bag)

It is a fluor and colored hollow ball which is used for reminding the residual volume of the fluid, especially for the patients’ night observation. 

Ball (in Murphy’s dropper)

It is a transparent hollow ball which is used for ceasing the process of infusion. 

Ball groove

It is used to fix the transparent ball in the Murphy’s dropper in order to cease the infusion

Pressure

That is a very simple physical problem.

Flow control cap

Sometimes, when patients moved his or her body, the flow control would be shifted, so that the flowing speed would be changed, and that might make some emergency condition on the patients

What is the advantage of it? 

• Innovative idea

• Lower cost

• practicability

Medical Needle Disposal (breif version)

Status: Current Methods Unsafe and something is costly.

Currently I am serving as a nurse in the hospital, and I use the medical needle almost all the time to do some medical therapy to my patients, but after the manipulation the method used to depart the needle from the pumping body is unsafe, it is the most original that you use your two hand to make them apart without any protection. However, as we all know, hospitals house large numbers of people who are sick and whose immune systems are often in a weakened state, what’s more, we do not know if the patient we have taken manipulation on have the HBV, HCV or HIV or not. So it is easer to happen with Nosocomial infections which are a result of treatment in a hospital or a healthcare service unit, but secondary to the patient's original condition. Infections are considered nosocomial if they first appear 48 hours or more after hospital admission or within 30 days after discharge in the hospital.

Why I made this device?

• The outgoing document of PRC’s ministry of health，the document states that the sharp               device used in the medical field must be recollected in a certain container which can ensure           the sharp device not harming the doctor and nurse.

• The high risk to nurses when they are disposing of used needles. (to protect nurses from the         infection something like HIV and Hepatitis and so on so forth)

What is it?

The design allows doctors and nurses working in harried conditions or developing countries to dispose of used needles easily and safely. 

What is the structure?

1. Protective funnel

The funnel, which is thick and large, can protect users’ hands from stab by the needles being discarded, as well as preventing liquid splash back.

2. Anti-rolling device

Just as the name, it is used to prevent the device rolling on the table and make it easily-managed.

3. The cap

It is the core design of this device, and let me tell you everything about how it get work and what is the advantage of it.

• 1).Valve

• 2).Central bore

• 3).The upper face of the cap

• 4).The funnel

4.the bottle

   The ordinary bottles, which are with the same size of the thread bottle cap, are all applicable.

(like the coke bottle, mineral water bottle and so on so forth)
