Detailed Description
(example 1)
This embodiment is a muscle medicine syringe, as shown in fig. 1 to 7, comprising a needle tube 1, a puncture needle 2, a connecting base 3 and two plungers 4.
One end of the needle tube is provided with two side-by-side and isolated sliding cavities 11, the other end of the needle tube is provided with a sealing plate 12 for sealing the same end opening of the two sliding cavities, the sealing plate is provided with two through holes 13, and each through hole is communicated with a corresponding sliding cavity.
Each plunger is positioned in a corresponding sliding cavity and can slide in the sliding cavity in a sealing way; each plunger is pulled outwards to suck the liquid medicine into the sliding cavity and push the liquid medicine inwards to discharge the liquid medicine.
The shape of each slide chamber is preferably circular, so that the shape of the radial section of the needle cannula in this embodiment is 8-shaped.
The position of each through hole is preferably deviated from the central position of a corresponding sliding cavity, namely an eccentric hole; a further preferred way is that the distance between the centres of the two eccentric holes is smaller than the distance between the centres of the two slide cavities.
The connecting seat comprises an 8-shaped seat plate 31, an 8-shaped sliding tube 32 arranged at one end of the seat plate and a puncture needle mounting seat 33 arranged at the other end of the seat plate.
The puncture needle 2 comprises a needle head 21 and a needle head seat 22 which is clamped and sleeved on a puncture needle mounting seat of the seat plate.
The 8-shaped seat plate is provided with two transfusion holes 311, the puncture needle mounting seat is provided with a liquid channel 331, and the two transfusion holes are communicated with the needle head of the puncture needle through the liquid channel.
The 8-shaped sliding pipe consists of two communicated arc-shaped sliding pipes 321, and each infusion hole is positioned in one corresponding arc-shaped sliding pipe; one end of the needle tube, which is provided with a closing plate, is inserted into the 8-shaped sliding tube.
The sealing plate of the needle tube is positioned in the 8-shaped sliding tube, the sealing plate is abutted against the wall surface of the 8-shaped seat plate and is in sealing fit with the wall surface of the 8-shaped seat plate, and the needle tube can be twisted in the 8-shaped sliding tube in a reciprocating mode for a certain angle.
In this embodiment, two limiting bosses 5 protruding outward along the needle tube radial direction are arranged on the outer wall of the needle tube, and an inward-concave limiting slide 322 and a guiding slide 323 communicated with the limiting slide are arranged on the inner wall of each arc-shaped sliding tube 321; each limiting boss is matched with a corresponding limiting slide way and is in interference fit with a corresponding guiding slide way;
when the needle tube is inserted into the 8-shaped sliding tube, each limiting boss is firstly inserted into a corresponding guiding slide way and then enters a corresponding limiting slide way, and at the moment, under the limiting action of the limiting slide ways on the limiting bosses, the needle tube can be twisted in the 8-shaped sliding tube in a reciprocating mode.
In the twisting process of the needle tube, each through hole can be communicated with or blocked from a corresponding infusion hole.
In the twisting process of the needle tube, the moving trajectory of each through hole is an arc line, so that the infusion hole can be arranged on the corresponding arc line, and the position of the infusion hole can meet the functions.
In the embodiment, the transfusion hole and the corresponding through hole are arranged at two ends of the moving track line of the through hole, and the displacement of the through hole and the corresponding transfusion hole can meet the function by presetting the length of the track line.
As shown in FIG. 6, at this time, the upper through hole and the upper infusion hole are in a communicated state, and at this time, the lower through hole and the lower infusion hole are in a completely deviated state, that is, a blocked state, and the upper through hole and the lower infusion hole cannot form a liquid path channel.
When the needle tube in fig. 6 is twisted to the position shown in fig. 7 along the direction of the arrow in fig. 6, the upper through hole and the upper infusion hole are in a complete deviation state, i.e., a blocking state, and cannot form a liquid path channel, and the lower through hole and the lower infusion hole are in a communication state to form the liquid path channel.
In fig. 6 and 7, the through-hole is shown by a broken line and the infusion hole is shown by a solid line in order to remove the through-hole and the infusion hole, respectively.
When the syringe is used, the connecting seat is held, the corresponding plunger can be pulled to draw in liquid medicine into the corresponding sliding cavity by twisting the needle tube along one direction until the needle tube cannot be twisted; after one sliding cavity finishes pumping the liquid medicine, the needle tube is twisted in the opposite direction until the needle tube cannot be twisted, and the other plunger is pulled, so that the liquid medicine can be pumped into the other sliding cavity; after the two sliding cavities are pumped with the liquid medicine, the liquid medicine can be firstly injected by twisting the needle tube.
