-1INTRAOSSEOUS INFUSION TRAINING SYSTEM
FIELD
This invention relates generally to an intraosseous infusion training system.
BACKGROUND
In the face of critical illness or trauma giving intravenous drugs, fluids or blood products can prove impossible due to collapse of blood vessels. Specialised needles have been developed which drill into the bone of the upper arm (head of the humerus), breast bone (sternum) or shin bone (tibia), which results in so-called intraosseous infusion.
The blood vessels within the bone cannot collapse because of the structure of the supporting honey comb-like bone. These techniques were a vital part of the damage control resuscitation chain of care developed by the United Kingdom Defence Medical Services in Afghanistan. This technique is now a standard part of the UK paramedic armamentarium and is of recognised importance in tactical medical situations.
Current intraosseous infusion training systems are provided by an artificial body portion comprising an artificial bone provided within a silicone (or similar soft plastic) based housing shaped to represent a portion of a human body. A problem exists however in that the production of such an artificial body portion is expensive and the life expectancy is short. This is because after the artificial bone has undergone needle insertion in the correct location on more than one occasion permanent holes are formed within the artificial bone. Therefore, upon re-use if a practitioner undergoing training happens to insert a needle into a pre-formed hole in the artificial bone then the feeling experienced will be significantly less resistant than into a part of the artificial bone that has not previous received a needle. Thus, the training aid has extremely limited life expectancy and is susceptible to misrepresentation of a real life situation.
-2Thus, it is desirable to provide an improved system which enables training in intraosseous infusion to take place.
Aspects and embodiments were conceived with the foregoing in mind.
SUMMARY
Viewed from a first aspect, there is provided an intraosseous infusion training system comprising an artificial body portion comprising a housing portion and an artificial bone section movable between a plurality of orientations relative to the housing portion to provide a plurality of access points at which the artificial bone section can be accessed.
A system in accordance with the first aspect enables intraosseous infusion training to be undertaken in a safe controlled environment, where the user experience repetitively stimulates an accurate real-life experience of injecting into bone. Thus, the training aid can be re-used a large number of times at different relative orientations before requiring replacement.
The artificial bone section can be moved between a plurality of orientations which enable the same artificial bone section to be used by multiple students wherein each student can access a different point on the artificial bone to insert the specialised needle. The artificial bone section is preferably rotatable relative to the housing.
The artificial bone section may comprise a sub-section of uniform cross-section.
Sub-section means at least a portion of the artificial bone section but could mean all of the artificial bone section.
The sub-section may be cylindrical. The effect of using a cylindrical sub-section of uniform cross section means that the artificial bone section is easy to rotate inside the housing. The artificial bone section preferably comprises an arm portion and a head portion. The arm portion preferably tapers outwardly to the head portion.
-3The artificial bone section is preferably accessible from externally of the housing. This enables a user to move the artificial bone relative to the housing.
The housing may partially house the artificial bone section such that a portion of the artificial bone section is exposed. The housing preferably cradles the artificial bone. This means that the user of the training aid does not have the housing impeding insertion of the needle into the exposed artificial bone section. The artificial bone and preferably the housing are beneficially covered by a covering material arranged to represent tissue of a patient. The tissue in real life situations may include skin, muscle, and fat. The covering is preferably polymeric and is preferably made of a silicone based material.
The artificial bone section may comprise a hollow inner core. The hollow inner core may contain fluid such as, for example, artificial blood.
In providing a hollow inner core where a fluid can be deposited the training system according to the first aspect can enable a needle to be used to penetrate the artificial bone section to extract the fluid from the hollow inner core.
The hollow inner core may comprise a plurality of discrete chambers. The discrete chambers may be defined by a wall inside the hollow inner core.
Each of the discrete chambers may be accessible from the exterior of the artificial bone section by a port to enable fluid to be deposited inside the chamber.
The port may comprise a one-way valve through which fluid may be deposited inside the chamber.
Alternatively, the port may comprise a valve or connector through which fluid may be deposited inside the chamber and removed from the chamber.
-4The artificial bone section may be removable from the housing. The effect of this is that the artificial bone section can be removed from the housing and replaced with another artificial bone section.
An artificial bone section in accordance with the first aspect may be sized to replicate any bone section on the human skeleton or any bone section on any animal skeleton.
Additionally, the artificial bone section may be scaled version of any bone section on the human skeleton or any animal skeleton.
A system in accordance with the first aspect may form part of a training mannequin.
An embodiment of the present invention will now be described, by way of example only, and with reference to the accompany drawings, in which:
Figure 1 illustrates a part of a training mannequin in accordance with the embodiment.
Figure 2 is a schematic perspective view according to an exemplary embodiment.
Figure 3 is a schematic representation of an exemplary embodiment.
Figure 4 illustrates an oblique open section of an artificial bone section in accordance with an exemplary embodiment, figure 4b a side view in ‘open’ section, and figure 4c as an oblique end ‘open’ section.
DESCRIPTION
We will now describe, with reference to Figure 1, a training mannequin 100 in accordance with the embodiment.
Training mannequin 100 comprises an artificial body portion 102 comprising a housing 104 in which an artificial bone section 106 is housed. The artificial bone section 106 may
-5be covered with a covering 105 comprising a silicon layer 105 shaped to represent a body form intended to simulate skin, muscle and other tissue.
Artificial bone section 106 comprises an upper substantially spherical enlarged section 108 and a lower cylindrical section 110. In this example the artificial bone section 106 is intended to simulate the proximal humerus bone which sits in the upper arm of a human being but this is for illustration only.
Further referring to Figures 2 and 3 the housing 104 is arranged to cradle the artificial bone section 106. Accordingly, as more clearly presented in Figure 3, a user of the apparatus undergoing training will inject directly through the covering 105 and into the artificial bone section 106 without having to inject through the housing 104. It can be seen that the artificial bone section 106 provided within the housing 104 is symmetrical about a plane through the centre of the artificial bone section 106 in the longitudinal axis. It will also be appreciated that whilst the artificial bone section 106 is not an identical replica of a real bone it is sufficiently similar to reflect a real life bone whilst also allowing rotation in the housing 104.
It will also be appreciated that the artificial bone section 106 beneficially projects from the covering 105 and housing 104 to enable the ease of movement between uses.
We will now describe, with reference to Figure 4, an oblique open section of an artificial bone section 106 in accordance with the embodiment.
The artificial bone section 106 comprises an inner core 114. A partition wall 112 runs along the length of the artificial bone section 106 which separates the inner core 114 into four discrete chambers respectively enumerated as 116a, 116b, 116c and 116d adjacent respectively enumerated sections of the artificial bone section, i.e. 106a, 106b, 106c and 106d.
Each of the enumerated four discrete chambers may be used to hold artificial blood, sometimes referred to as “theatrical blood”. Artificial blood may be placed in the
-6respective chamber through a respective port 120 or plurality of ports 120a-d as best represented in figures ab and 4c to correspond to the associated chambers 116a-d. The port(s) may comprise a two-way valve or connector which enables the artificial blood to be deposited in the respective chamber and removed from the respective chamber.
Referring now to the figures in combination the artificial bone section 106 sits in the housing 104 but is entirely removable from the housing 104. The substantially spherical shape of the upper substantially spherical enlarged section 108 and the cylindrical shape of the lower cylindrical section 110 enable the artificial bone section 106 to be easily moved in the housing 104 to expose another aspect of the artificial bone section.
Therefore a first trainee may practice intraosseous infusion by penetrating the artificial bone section 106a which is adjacent chamber 116a with a needle to penetrate the inner core 114 to extract artificial blood from a respective chamber 116a. Then a supervisor may simply move the artificial bone section 106 by simply rolling it inside the housing to expose another section 106b of the artificial bone section 106. This section is adjacent chamber 116b which enables a second trainee to practice intraosseous infusion by penetrating the now exposed section of the artificial bone section 106b to extract artificial blood from the respective chamber 116b.
When the artificial bone section 106 has been used a large number of times to train a large number of trainees in intraosseous infusion it may be removed from the housing 104 and replaced with a further artificial bone section. Although the covering 105 simulating the skin, muscle and other tissue will also wear and eventually require replacing such a material can withstand many needle insertions without a significant impact upon the ‘feel’ experienced by a user.
It should be noted that the above mentioned embodiment illustrates rather than limits the invention and that those skilled in the art will be capable of designing many alternative embodiments without departing from the scope of the invention as defined by the appended claims. In the claims, any reference signs placed in parentheses shall not be construed as limiting the claims. The wording “comprising”, “comprises” and the like,
-7does not exclude the presence of elements or steps other than those listed in any claim or the specification as a whole. In the present invention, “comprises” means “includes or consists of’ and comprising means including or consisting of. The singular reference of an element does not exclude the plural reference of such elements and vice versa. In a device claim enumerating several means, several of these means may be embodied by one and the same item of hardware. The mere fact that certain measures are recited in mutually different dependent claims does not indicate that a combination of these measures cannot be used to advantage.
