Description
-I-
Blood Vessel Training Model The present invention relates to a medical training aid in the form of a model for providing a realistic means of training personnel in accessing blood vessels Cannulation of blood vessels such as peripheral veins that lie just below the skin surface is an important and standard requirement for medical practitioners. In addition, for patients who are severely ill along with those having sustained major life-threatening injuries, cannulation of specific central blood vessels is an integral part of their management. The central vessels include the femoral vessels at the groin, subclavian vein at the shoulder and the jugular vein in the neck. In other scenarios, it can be necessary to dissect through into a patient to expose the simulated blood vessels and achieve direct control of the flow of simulated blood through the vessel or its cannulation.
Models do exist to help personnel acquire these skills. Such models comprise a body representative of a human or part of a human, having a flexible plastic tube simulating a blood vessel passing therethrough. The tube has a low stiffness, being deformable under its own weight and has a thin wall designed as far as possible to represent the thin wall of a vein or artery. Whilst such a model when new provides a reasonable representation of a real patient, there is a significant problem in that with repeated use the model quickly becomes unrealistic due to the tendency of the tube to leak after repeated puncture.
It is considered possible to exchange the leaking tube for a new one, however there are technical difficulties with such an approach. This is particularly due to the low stiffness and associated low thickness of the tube wall meaning replacing a tube is difficult due to the requirement to feed the tube through an elongate channel in the body. This is made more difficult by the fact the tube has to be retained in position and may not easily slide in and out of the channel, further meaning that insertion is difficult. This is particularly true where access is required to the central vessels which for realism must be embedded significantly deeper within the model. Thus, existing models are typically used for a short period of time during which they actually provide a realistic model, and are then either used in an unrealistic state, for example where there is significant leakage, or simply discarded and replaced with an entirely new model.
It is therefore desirable to provide an improved training model for simulating a human or 5 part of a human that realistically simulates accessing a blood vessel which addresses the above described problems and/or which offers improvements generally.
According to an aspect of the present invention there is a blood vessel training model comprising: a body for simulating a human body or part thereof defining a receiving formation therein; an insert comprising a fluid channel defined therein for positioning into the receiving formation; wherein the insert has a longitudinal length extending between first and second ends and the fluid channel extends longitudinally, the insert comprises a transverse axis extending transversely relative to the longitudinal axis that extends through at least a first insert wall thickness, the width of the fluid channel and a second insert wall thickness, and where the ratio of the width of the fluid channel to at least one of the first and/or second insert wall thicknesses in the transverse axis is no greater than 4:1.
Also according to an aspect of the present invention there is an insert arranged for positioning into receiving formation of a body, the body simulating a human body or part thereof of a blood vessel training model, the insert comprising a fluid channel defined therein representative of a blood vessel, wherein the insert has a longitudinal length extending between first and second ends and the fluid channel extends longitudinally, the insert further comprises a transverse axis extending transversely relative to the longitudinal axis that extends through at least a first insert wall thickness, the width of the fluid channel and a second insert wall thickness, and where the ratio of the width of the fluid channel to at least one of the first and/or second insert wall thicknesses in the transverse axis is no greater than 4:1.
A ratio of less than 4:1 means that the maximum permitted transverse channel thickness is four times greater than the transverse insert thickness. This contrasts with prior art arrangements whereby the insert may be formed of a flexible tube, and where the ratio of the transverse channel thickness to the transverse insert thickness is in the order of 32:1.
For example, a flexible tube utilised in the art may have a channel diameter of 8mm and a wall thickness of 0.25mm.
By increasing the first and/or second insert wall thickness relative to the channel width the insert is more resilient and easier to replace in the body. This means the insert can be provided as being inflexible without application of an applied force. This means that the insert will retain its shape without deforming unless there is an applied force, in contrast to known simulators where an elongate tube having a thin transverse wall thickness in comparison to a large transverse channel thickness are utilised. These elongate tubes are flexible so will bend without an applied force other than gravity. However, by decreasing the ratio the stiffness increases and the ability to replace in the body is increased.
The ratio is preferably between 4:1 and 0.3:1. Preferably the ratio is between 0.5:1 and 2:1. As an example only, the ratio may be 1.33:1, where the channel insert width is lOmm and the first and/or second insert wall thickness is 7.5mm.
The stiffness of the insert is beneficially such that the insert does not substantially deform under its own weight.
It will be appreciated that the width of the fluid channel may vary in the longitudinal axis.
Furthermore, the ratio of the width of the fluid channel to at least one of the first and/or second insert wall thicknesses in the transverse axis may vary in the longitudinal axis. Thus, the external shape of the insert and/or the width of the fluid channel may change longitudinally. This is particularly beneficial for simulating areas of the body such as the stomach to the groin where the diameter of a blood vessel will naturally reduce in diameter.
The fluid channel is preferably cylindrical, however, it will be appreciated that other shapes are possible The transverse axis beneficially extends through a point equidistant from the wall defining the fluid channel.
The insert may comprise a plurality of channels.
According to another aspect of the present invention there is a blood vessel training model comprising: - a body for simulating a human body or part thereof defining a receiving formation therein; - an insert comprising a fluid channel defined therein for positioning into the receiving formation, the insert comprising a longitudinal length extending between first and second ends, the fluid channel extending lengthwise from an inlet at the first end, and wherein the fluid 15 channel terminates before the second end.
Also according to this aspect of the present invention there is an insert arranged for positioning into receiving formation of a body, the body simulating a human body or part thereof of a blood vessel training model, the insert comprising a fluid channel defined therein representative of a blood vessel, the insert comprising a longitudinal length extending between first and second ends, the fluid channel extending lengthwise from an inlet at the first end, and wherein the fluid channel terminates before the second end.
Accordingly, the channel beneficially does not extend through the second end of the insert.
The insert can therefore be readily inserted into the receiving formation and the insert does not therefore need to be fed through the receiving formation. This can be very difficult as it is desirable that there is sufficient friction between the insert and the walls defining the receiving formation, which hinders attempts to feed the insert therethrough This also means that access to the channel can be achieved via one end of the insert, and as such complexity of connection of the channel to a fluid source is reduced The second end of the insert is preferably shaped for ease of insertion into the body. The second end is preferably rounded and may be dome shaped. The second end may comprise a head. The head is preferably arranged to project outwardly in a direction transverse to the longitudinal length of the insert. The head may be received in a corresponding socket in the body for restricting relative movement between the insert and the body.
It may be desirable in some embodiments that connection is enabled to a pump for simulating pulsatile flow for simulating arterial and vein circulation. In such an embodiment the fluid channel may comprise an inward fluid channel portion extending from the inlet towards the second end of the insert, and an outward fluid channel portion extending lengthwise toward an outlet at the first, and a bridge portion connecting the inward and outward fluid channel portions. The inlet and outlet are beneficially configured to attach to a peristaltic pump for example meaning blood flow through the body can be simulated.
The fluid channel is beneficially integrally moulded within the body.
The insert may comprise a groove extending around a peripheral edge of the insert. The groove is preferably closer to the first end than the second end. The groove is preferably adjacent the first end. The insert preferably projects from the body, and the groove is in a portion of the insert that is projecting from the body. This allows access to the groove to enable a source of fluid to be connected to the insert and cinched tight through compression into the groove.
According to another aspect of the invention there is a blood vessel training model comprising: a body for simulating a human body or part thereof defining a receiving formation therein; an insert comprising a fluid channel defined therein for positioning into the receiving formation; wherein the insert comprises an external surface formation for restricting relative movement between the insert and a wall of the body defining the receiving formation.
Also according to this aspect of the present invention there is an insert arranged for positioning into receiving formation of a body, the body simulating a human body or part thereof of a blood vessel training model, the insert comprising a fluid channel defined therein representative of a blood vessel, wherein the insert comprises an external surface formation for restricting relative movement between the insert and a wall of the body defining the receiving formation.
The external surface formation may comprise a head. The head is preferably arranged to project outwardly in a direction transverse to the longitudinal length of the insert. The insert preferably comprises a first trailing end and a second leading end, and the head is preferably at the leading end of the insert. The head may be received in a corresponding socket in the body. This assists in restricting relative movement between the insert and the body.
According to another aspect of the present invention there is a blood vessel training model comprising: - a body for simulating a human body or part thereof defining a receiving formation therein; -an insert comprising a fluid channel defined therein for positioning into the receiving formation; wherein the stiffness of the insert is such that the insert substantially does not deform under its own weight.
Also according to this aspect of the present invention there is an insert arranged for positioning into receiving formation of a body, the body simulating a human body or part thereof of a blood vessel training model, the insert comprising a fluid channel defined therein representative of a blood vessel, wherein the stiffness of the insert is such that the insert substantially does not deform under its own weight In an alternative or additional definition to the stiffness of the insert being such that the insert substantially does not deform under its own weight, according to this aspect of the invention the stiffness of the insert is beneficially such that the insert as a whole returns to its original shape after an applied force is removed The stiffness of the body is the extent to which it resists deformation in response to an applied force. It will be appreciated that the insert is elastically deformable. The insert has an external surface configuration and the receiving formation has a configuration such that the insert elastically deforms during insertion into the receiving formation. It is preferable that the insert remains elastically deformed when retained in the receiving formation in order to provide a secure engagement.
It will be appreciated that in each defined aspect of the invention, the fluid channel is representative of a blood vessel The blood vessel may be a peripheral blood vessel, but is even more preferably a central blood vessel.
It will be appreciated that in each defined aspect of the invention, the insert is preferably formed from silicone. In particular, it is beneficial that a wall defining the fluid channel if formed of silicone. The silicone beneficially extends laterally from the wall outwardly toward the external surface of the insert. By utilising silicone as the material of the insert, repeated cannulation is achieved as the silicone is capable of self-sealing following puncture. This means that the possibility of fluid leakage is significantly reduced.
It will be appreciated that in each defined aspect of the invention the insert may include a reinforcing structure. The reinforcing structure may comprise at least a partial covering.
The reinforcing structure is preferably provided for providing durability and structural integrity to the insert, and at the same time designed to minimise any interruption to the operation of cannulation or dissection. Accordingly, the reinforcing structure may comprise a mesh, such as a nylon mesh. The insert is preferably also structurally reinforced adjacent the inlet to the fluid channel for increasing strength in an area where for connection to tubes, for example the tubes of a pump.
It will be appreciated that in each defined aspect of the invention, there is no additional tube provided within the insert. It will be appreciated that in each defined aspect of the invention the fluid channel is beneficially integrally moulded within the body.
It will be appreciated that in each defined aspect of the invention the cross sectional shape of the insert may be circular, oval, square, rectangular, figure of eight or partial figure of eight.
It will be appreciated that in each defined aspect of the invention the insert comprises a 10 width, and the width of the insert is between 25mm and 70mm. It will therefore be appreciated that the average width of the insert is greater than a known tube. The longitudinal length is preferably between lOmm and 300mm It will be appreciated that in each defined aspect the receiving formation is preferably 15 configured to substantially min-or the external surface configuration of the insert.
The cross sectional profile of the fluid channel may change along the longitudinal length of the fluid channel. The fluid channel has first and second ends and may have a compression zone located lengthwise between the first and second ends that is compressible between an open configuration and a closed configuration in which flow through the fluid channel is blocked, where the compression zone has a compression axis arranged transverse to the length of the fluid channel along which a compression force is applied to the fluid channel in use, and the compression zone has a cross sectional shape having a first axis aligned with the compression axis and a second axis arranged transverse to the first axis, and the diameter of the fluid channel along the second axis is greater than diameter along the first axis to enable the fluid channel to be more easily compressed to the closed configuration. This configuration allows compression of the fluid channel to stem flow of fluid more easily than a circular cross sectional profile, and provides a more realistic experience for a user in the event stopping the fluid flow is a necessary part of the procedure.
It will be appreciated that in each defined aspect the differentiating feature from another aspect may equally be a preferred feature of another aspect, and each of the preferred features are preferred features of a blood vessel training model and insert as described herein.
Aspects of the present invention have been described by way of illustration only with 5 reference to the accompanying Figures where: Figure 1 is a schematic representation of a partial human body having an insert positioned therein.
Figure 2a, b and c are schematic representations of an insert for insertion into a respective receiving formation in a body in perspective and cross sectional representations according to illustrative embodiments of the present invention Referring to Figure 1, there is a schematic representation of a mannequin 2 of an upper body forming a body 2 into which a receiving formation 4 is provided. The actual body 2 is shown in solid lines, whereas the remainder of an upper body is presented in dashed lines for increased context. An insert 6 is removably positioned in the receiving formation 4 and in the illustrative embodiment presented is connected via a tube to a source of fluid source 7 in order that fluid can pass into the fluid channel 8, where the fluid is representative of blood. It will be appreciated that in this embodiment the fluid channel 8 is representative of the subclavian vein at the shoulder, but it could equally be utilised to represent the jugular vein in the neck or femoral vessels at the groin as examples only.
Referring now to Figure 2(a), an insert 4 is shown in more detail in cross section and perspective view respectively for insertion into the body 2. The insert 6 comprises a longitudinal length extending between first and second ends 10,12, where the fluid channel 8 extends lengthwise from an inlet 14 at the first end 10 towards the second end 12. In the embodiment presented the fluid channel terminates before the second end 12 and accordingly the channel 8 does not extend through the second end 12 of the insert 6. The insert 4 can therefore be readily inserted into the receiving formation 4 and the insert 6 does not therefore need to be fed through the receiving formation 4. This can be very difficult as it is desirable that there is sufficient friction between the insert and the walls defining the receiving formation 4, which hinders attempts to feed the insert therethrough. The second end 12 of the insert 6 is rounded for ease of location into the receiving formation The insert 6 further comprises a groove positioned adjacent the first end 10 extending around a peripheral edge of the insert for allowing cinching thereto of a tube for connection to a fluid source. The groove 16 is shown as extending around the entire perimeter of the peripheral edge of the insert 6, however it will be appreciated that it may only partially extend around the perimeter.
As described and shown in the Figures the fluid channel 8 extends longitudinally. A transverse axis is represented by arrow 17 and the insert 6 has a transverse channel width which is the diameter of the fluid channel assuming the fluid channel is cylindrical or frustroconical. This is represented as distance 18. The insert comprises a first insert wall thickness 20 and second insert wall thickness 21 where the fluid channel width 18, first insert wall thickness 2 and second insert wall thickness 21 extend in the same transverse axis. The first and second insert wall thicknesses 20,21 extend transversely between an external surface of the insert 6 and the fluid channel 8. The ratio of the channel width 18 to at least one of the first and second insert wall thicknesses 20,21is less than 4:1. In the embodiment as presented in Figure 2a, the ratio is approximately 1:1, meaning the thickness of the insert 6 as a whole is twice the fluid channel width 18, made up of the first and second insert wall thicknesses 20.21 and the fluid channel thickness 18.
A ratio of less than 4:1 means that the maximum permitted transverse channel thickness is four times greater than the transverse insert thickness. By reducing the ratio of the transverse channel thickness to the transverse insert thickness, the insert 6 is more resilient and easier to replace in the body 4. This means that the insert 6 has the required stiffness. The ratio may be between 4:1 and 0.3:1. Preferably the ratio is between 0.5:1 and 2:1.
It will be appreciated that the first and second insert wall thicknesses 20,21 may be different to one another. However, it is important that the overall stiffness of the insert 6 is retained.
Referring now to Figure 2b, a further illustrative embodiment of an insert 6 is presented. In this embodiment the second end 12 comprises a head which is arranged to project outwardly in a direction transverse to the longitudinal length of the insert. The head may be received in a corresponding socket in the body for restricting relative movement between the insert and the body through the shoulder 24 of the head abutting against a corresponding formation in the receiving formation 4.
The cross sectional profile of the fluid channel 8 in this embodiment may change along the longitudinal length of the fluid channel. This change is independent of the requirement for the provision of the head at the second end 12. The fluid channel 8 has first and second ends at the inlet 14 and the opposing distal end 26 respectively (although it will be appreciated the distal end 26 may extend through the second end 12 of the insert 6) and may have a compression zone 28 located lengthwise between the first and second ends 14,26 that is compressible between an open configuration and a closed configuration in which flow through the fluid channel 8 is blocked. The compression zone 28 has a compression axis transverse to the length of the fluid channel along which a compression force is applied to the fluid channel in use, and the compression zone has a cross sectional shape having a first axis aligned with the compression axis and a second axis arranged transverse to the first axis, and the diameter of the fluid channel along the second axis is greater than diameter along the first axis to enable the fluid channel to be more easily compressed to the closed configuration. The cross sectional profile may, for example, be oval shaped. This configuration allows compression of the fluid channel to stem flow of fluid more easily than a circular cross sectional profile, and provides a more realistic experience for a user in the event stopping the fluid flow is a necessary part of the procedure.
Referring to Figure 2c, a further illustrative embodiment is presented. In this embodiment anatomical accuracy can be enhanced by inclusion of the paired artery in the simulation model. Thus, the fluid channel may comprise an inward fluid channel portion 8a extending from the inlet 14 towards the second end of the insert 6, and an outward fluid channel portion 8b extending lengthwise toward an outlet at the first end 10, and a bridge portion connecting the inward and outward fluid channel portions. The inlet and outlet are beneficially configured to attach to a peristatic pump for example meaning pulsed blood flow can be provided through a simulated vein and artery.
Aspects of the present invention have been described by way of example only and it will be apparent to the skilled addressee that modifications and variations may be made without departing from the scope of protection afforded by the appended claims.
