Training device for chewing and swallowing
View Patent ↗The training device for chewing and swallowing can be used by patients who have difficulty chewing and/or swallowing to assist them to learn how to chew and swallow. The device includes a bolus delivery cylinder and a plunger. The bolus delivery cylinder can include a cylindrical housing having a peripheral wall and a hollow interior. The plunger can be slidably received in the cylindrical housing and secured thereto. In some embodiments the peripheral wall can be perforated. The interior of the housing is configured to accommodate small pieces of food. The bolus delivery cylinder can be made from a transparent, flexible material, such as silicon.
1. A training device for chewing and swallowing, comprising:
a cylindrical plunger having a distal end and an opposing proximate end, the proximate end including a plunger lock mechanism; and
a hollow bolus delivery cylinder configured to slidably receive the cylindrical plunger, the cylinder having a closed distal end, an open proximate end, a cylindrical handle portion and a cylinder lock mechanism adjacent the proximate end, a cylindrical chewing member adjacent the distal end, and a circular shield flange separating the handle portion from the chewing member, wherein
the cylinder lock mechanism is configured to engage the plunger lock mechanism to secure the cylindrical plunger to the hollow bolus delivery chamber; thereby preventing the cylindrical plunger from sliding further into the hollow bolus delivery chamber and preventing the cylindrical plunger from sliding further out of the hollow bolus delivery chamber.
2. The training device for chewing and swallowing as recited in claim 1 , wherein the bolus delivery cylinder is made from silicon.
3. The training device for chewing and swallowing as recited in claim 1 , wherein:
the cylinder lock mechanism includes a central plate and locking hooks extending axially from opposite sides of the plate; and
the plunger lock mechanism includes radially extending receiving tabs;
whereby the plunger can be rotated within the bolus delivery cylinder until the locking hooks engage the tabs to secure the cylindrical plunger to the hollow bolus delivery cylinder.
4. The training device for chewing and swallowing as recited in claim 1 , wherein:
a peripheral wall of the chewing member is perforated and includes a plurality of holes extending therethrough.
5. The training device for chewing and swallowing as recited in claim 4 , wherein the plurality of holes are arranged in a linear array that extends axially along one side of the chewing member.
6. The training device for chewing and swallowing as recited in claim 5 , wherein the plurality of holes comprises five holes.
7. The training device for chewing and swallowing as recited in claim 4 , wherein the plurality of holes comprises from five to fifteen holes.
8. The training device for chewing and swallowing as recited in claim 1 , wherein:
the handle portion has a first diameter;
the chewing member has a second diameter;
the shield flange has an outer circular edge with a third diameter; and
the first diameter is greater than the second diameter and the third diameter is greater than the first diameter.
9. The training device for chewing and swallowing as recited in claim 1 , wherein the shield flange further comprises:
an upper frustoconical surface that extends from the handle portion to an outer edge of the shield flange.
10. A training kit for chewing and swallowing, comprising:
a cylindrical plunger having a distal end and an opposing proximate end, the proximate end including a plunger lock mechanism; and
at least one hollow bolus delivery cylinder configured to slidably receive the cylindrical plunger, the cylinder having a closed distal end, an open proximate end, a cylindrical handle portion with a cylinder lock mechanism adjacent the proximate end, a cylindrical chewing member adjacent the distal end, and a circular shield flange separating the handle portion from the chewing member, wherein
the cylinder lock mechanism is configured to engage the plunger lock mechanism to secure the cylindrical plunger to the hollow bolus delivery chamber; thereby preventing the cylindrical plunger from sliding further into the at least one hollow bolus delivery chamber and preventing the cylindrical plunger from sliding further out of the at least one hollow bolus delivery chamber.
11. The training kit as recited in claim 10 , wherein the at least one bolus delivery cylinder is made from silicon.
12. The training kit as recited in claim 10 , wherein
the at least one bolus delivery cylinder comprises one bolus delivery cylinder;
the chewing member includes a solid peripheral wall; and
the plunger and the peripheral wall form a closed, sealed chamber when the plunger is inserted into the handle portion.
13. The training kit as recited in claim 11 , wherein
the at least one bolus delivery cylinder comprises a first bolus delivery cylinder and a second bolus delivery cylinder;
the chewing member of the first bolus delivery cylinder comprises a solid peripheral wall; and
the chewing member of the second bolus delivery cylinder comprises a perforated peripheral wall.
14. The training kit as recited in claim 13 , wherein the perforated peripheral wall includes a plurality of holes arranged in a linear array that extends axially along one side thereof.
15. The training kit as recited in claim 14 , wherein the plurality of holes comprises five holes.
16. The training kit as recited in claim 13 , further comprising a third bolus delivery cylinder, wherein:
the chewing member of the third bolus delivery cylinder includes a perforated peripheral wall having a greater number of holes than the chewing member of the second bolus delivery cylinder.
17. The training kit as recited in claim 16 , wherein the chewing member of the second bolus delivery chamber comprises five holes and the chewing member of the third bolus delivery member comprises ten holes.
