As shown in fig. 2 and 3, one embodiment of the present invention provides a medical device for hemostasis, which includes a barrel 1, a sheet ejection mechanism, a sheet pushing mechanism, and a heating mechanism. A tablet storage bin 101 is arranged in the barrel 1, and the tablet storage bin 101 is used for storing the hemostatic tablets 100. Preferably, magazine 101 is divided by the bore of barrel 1. The head of the gun barrel 1 is provided with a sheet outlet channel 2. The sheet outlet channel 2 has a sheet inlet 201 and a sheet outlet, and the hemostatic sheet 100 enters the sheet outlet channel 2 from the sheet inlet 201 and leaves the sheet outlet channel 2 from the sheet outlet. As shown in fig. 4, the sheet outlet channel 2 is configured as a channel for sliding one side of the hemostatic sheet 100 out of the sheet outlet first and then out of the other side. Preferably, the sheet outlet channel 2 is a flat channel, the sheet outlet channel 2 is only used for accommodating a single hemostatic sheet 100, and the sliding direction of the hemostatic sheet 100 in the sheet outlet channel 2 is perpendicular to the thickness direction thereof.

The sheet discharging mechanism is used for sequentially feeding the hemostatic sheets 100 in the sheet storage bin 101 into the sheet discharging channel 2 from the sheet inlet 201. The sheet pushing mechanism is used for pushing the hemostatic sheet 100 in the sheet outlet channel 2 out of the sheet outlet. The heating mechanism is used for heating the hemostatic tablet 100 in the tablet outlet channel 2 to improve the hemostatic effect of the hemostatic tablet 100.

As shown in fig. 4, a door 4 is provided at the sheet outlet, and a burred surface 41 is provided on the door 4. The door 4 is arranged to open the sheet outlet at the time of sheet discharge and the pricking surface 41 is in contact with the back surface of the hemostatic sheet 100. Preferably, the door body 4 may be a swing door. One end of the door body 4 is rotatably connected to the upper side of the sheet outlet, and the other end of the door body 4 is adhered with a burl cloth having the aforementioned burl surface 41. In order to facilitate the installation of the felt, preferably, the other end of the door body 4 has an inward concave installation groove, the felt is adhered and fixed in the installation groove, and the bristles of the felt protrude out of the door body 4 so as to be conveniently contacted with the back surface of the hemostatic sheet 100.

The door body 4 may further be provided with a torsion spring to provide a force for closing the sheet outlet by the door body 4, so that the burr surface 41 on the door body 4 can be tightly attached to the back surface of the sheet 100 when the sheet 100 slides out of the sheet outlet.

In the above example, when the medical device for hemostasis is used, the hemostatic tablet 100 in the tablet storage 101 is firstly pushed into the tablet outlet channel 2 from the tablet inlet 201 by the tablet outlet mechanism; then the sheet pushing mechanism pushes the hemostatic sheet 100 to slide out of the sheet outlet, when the hemostatic sheet 100 slides out of the sheet outlet, one side of the hemostatic sheet firstly slides out, the other side of the hemostatic sheet slides out later, and the burr surface 41 on the door body 4 is contacted with the back surface of the hemostatic sheet 100 in the sliding-out process; because the frictional resistance of the pricking surface 41 on the door body 4 is large, the ejection speed of the hemostatic sheet 100 can be reduced when the door body contacts the hemostatic sheet 100, so that the hemostatic sheet 100 can be ejected to the wound of the patient at a low speed, and the pain of the patient is relieved.

Here, it should be noted that: the hemostatic sheet is a front side and the other side is a back side.

In order to further reduce the emission speed of the hemostatic sheet 100, preferably, the back surface of the hemostatic sheet 100 may be provided with a round hair region for bonding with the barbed surface 41, so that when the hemostatic sheet 100 slides out of the sheet outlet, the barbed surface 41 on the door body 4 contacts with the round hair region, and the barbed hair hooks the round hair, so that the sliding resistance of the hemostatic sheet 100 is further increased, and the emission speed of the hemostatic sheet 100 is further reduced.

In a specific application example, the back surface of the hemostatic sheet 100 may be adhered with a circular felt having the circular felt region. In order to save cost, it is preferable to attach a circular felt only to a partial area of the back surface of the hemostatic sheet 100.

As shown in fig. 4, the sheet discharging passage 2 is disposed obliquely downward with respect to the barrel 1, so that the hemostatic sheet 100 can be obliquely discharged from the sheet discharging passage 2. One side of the hemostatic tablet 100 ejected obliquely can be contacted with the wound of the patient first, and the other side of the hemostatic tablet 100 is put down slowly under the action of the bristles, so that the hemostatic tablet 100 is convenient to place on the wound of the patient slowly, and pain of the patient is further relieved.

In order to realize the function of the aforementioned sheet pushing mechanism, the sheet pushing mechanism is enabled to push the hemostatic sheet 100 in the sheet outlet channel 2 out of the sheet outlet, as shown in fig. 5 and 6, the aforementioned sheet pushing mechanism may include a first driving mechanism and a pushing member 9. The first driving mechanism is used for driving the pushing piece 9 to move along the piece outlet channel 2 so as to push the hemostatic piece 100 out. Preferably, the first driving mechanism may include a first connecting string 5 and a trigger 3 connected to the barrel 1, the trigger 3 being a rotating member. The pushing member 9 is provided with a first connecting portion 91, and the first connecting portion 91 may be a connecting column. As shown in fig. 2, the first connection cord 5 has one end connected to the first connection portion 91 and the other end connected to the rotation shaft 31 of the trigger 3. As shown in fig. 4, the trigger 3 is used for driving the pushing piece 9 to move along the sheet outlet channel 2 through the first connecting rope 5 when being pulled. Specifically, when the trigger 3 is pulled, the rotating shaft 31 of the trigger 3 rotates and winds the first connecting cord 5 to pull the pushing member 9 to move. In this example, the hemostatic sheet 100 is ejected out of the sheet opening by pulling the trigger 3, which is relatively convenient.

In order to improve the motion precision of the pushing part 9, preferably, a sliding groove may be provided on the side wall of the sheet outlet channel 2, and a sliding block is provided on the pushing part 9, and the sliding block is in sliding fit with the sliding groove. The sliding groove can limit and guide the movement of the pushing piece 9, so that the pushing piece 9 moves along a set track.

As shown in fig. 2 to 4, the gun body of the medical device for hemostasis may further include an auxiliary wheel 10 for the first connecting rope 5 to wind around, so as to adjust the advancing direction of the first connecting rope 5, so that the pushing member 9 is pulled by the first connecting rope 5 more smoothly.

As shown in fig. 4, a first torsion spring 32 may be disposed on the rotating shaft 31, and the first torsion spring 32 is used for returning the trigger 3, so as to save labor. Wherein, when the trigger 3 is pulled, the rotating shaft 31 of the trigger 3 winds the first connecting rope 5; when the trigger 3 is reset, the rotary shaft 31 of the trigger 3 releases the first connecting cord 5, so that the pusher 9 can be driven back to the initial position.

In order to prevent the hemostatic tablet 100 entering the tablet inlet 201 from automatically sliding down along the tablet outlet channel 2 under the action of its own gravity, it is preferable that, as shown in fig. 5, a button 11 is provided on a sidewall of the tablet outlet channel 2, and the button 11 is configured to extend into the lower side of the tablet inlet 201 to prevent the hemostatic tablet 100 from automatically sliding down.

As shown in fig. 5, the aforementioned sheet inlet 201 may be disposed at a side surface of the sheet outlet channel 2, and the sheet outlet channel 2 has the accommodating section 17. The accommodating section 17 is located on a side of the sheet inlet 201 away from the sheet outlet, and the accommodating section 17 is used for accommodating the pushing member 9 to protect the pushing member 9 and prevent the pushing member 9 from being damaged.

Furthermore, the aforementioned sheet pushing mechanism may further include a second driving mechanism, and the second driving mechanism is configured to drive the pushing member 9 to return to the accommodating section 17, so that the pushing member 9 can automatically reset after pushing the hemostatic sheet 100 out of the sheet outlet, thereby having the effect of saving manpower. As shown in fig. 2, the second driving mechanism may include a second connecting string 8 and a second connecting portion 92 provided on the pushing member 9, and the second connecting portion 92 may be a connecting column or the like. The sheet outlet channel 2 is provided with a rotating shaft 6. One end of the second connecting rope 8 is connected to the second connecting portion 92, and the other end is connected to the rotating shaft 6. And a second torsion spring 7 is arranged on the rotating shaft 6, and the second torsion spring 7 is used for driving the rotating shaft 6 to rotate so as to drive the pushing piece 9 to return through the second connecting rope 8. Specifically, when the trigger 3 is pulled, the first connecting rope 5 drives the pushing member 9 to push the hemostatic sheet 100 out of the sheet outlet, and meanwhile, the pushing member 9 pulls the second connecting rope 8 to enable the rotating shaft 6 to pay off the second connecting rope 8 and enable the second torsion spring 7 to generate elastic deformation; when the trigger 3 is loosened, the rotating shaft 31 of the trigger 3 releases the first connecting rope 5, meanwhile, the second torsion spring 7 releases elastic force, the rotating shaft 6 winds the second connecting rope 8, the second connecting rope 8 pulls the pushing piece 9 to return to the initial position, so that the pushing piece 9 can automatically return when a user loosens the trigger 3, and the use is convenient.

As shown in fig. 2, the side wall of the sheet outlet passage 2 may further include a guide groove 21 penetrating the inside, and the first connecting portion 91 and the second connecting portion 92 both extend out of the guide groove 21 and are slidably engaged with the guide groove 21.

In order to realize the function of the sheet discharging mechanism, the sheet discharging mechanism can sequentially feed the hemostatic sheets 100 in the sheet storage chamber 101 into the sheet inlet 201, as shown in fig. 5, and the sheet discharging mechanism can include the push plate 13 and the first elastic member 14. The push plate 13 is movably disposed in the tablet storage bin 101, preferably, the push plate 13 is in sliding fit with a side wall of the tablet storage bin 101, the tablet inlet 201 is a hemostatic tablet outlet of the tablet storage bin 101, and the push plate 13 can be relatively close to or far from the tablet inlet 201. The first elastic member 14 is used for pushing the push plate 13 to make the hemostatic tablet 100 enter the tablet inlet 201, so that the hemostatic tablet 100 can be automatically fed. Wherein, the elastic element can be a spring or flexible rubber, etc.

In order to ensure the movement precision of the aforementioned push plate 13, it is preferable that a sliding groove is formed on the side wall of the sheet storage bin 101, a sliding block is fixed on the push plate 13, the sliding block is in sliding fit with the sliding groove, and the push plate 13 is relatively close to or far from the sheet inlet 201 along the sliding groove.

As shown in fig. 5, the medical device for hemostasis of the present invention may further include a thrust piece 15, where the thrust piece 15 is used to prevent the next hemostatic piece 100 from entering the ejection channel 2 when the ejection mechanism pushes the hemostatic piece 100, so as to prevent interference with the movement of the ejection mechanism. In a specific example, when the ejection channel 2 has the accommodating section 17 and the ejection mechanism includes the ejection member 9, as shown in fig. 6, the thrust member 15 is movably disposed in the accommodating section 17 and located on a side of the ejection member 9 away from the ejection port, and the thrust member 15 is configured to extend into the ejection port 201 to prevent the hemostatic sheet 100 from entering. Specifically, when the pushing member 9 pushes the hemostatic sheet 100 entering the sheet inlet 201 to leave, the loading position of the sheet inlet 201 is empty, and the next hemostatic sheet 100 has a tendency to automatically enter the sheet inlet 201 under the elastic force of the first elastic member 14, and the thrust member 15 extends into the sheet inlet 201, so that the next hemostatic sheet 100 can be prevented from entering the sheet inlet 201. When the pushing member 9 finishes feeding the hemostatic sheets 100 and returns, the pushing member 9 pushes the thrust piece 15 to return to the accommodating section 17 together to leave the loading position, and at this time, the first elastic piece 14 pushes the next hemostatic sheet 100 to enter the sheet inlet 201 to wait for the next sheet discharge.

In the above example, in order to save labor and realize automatic control of the thrust piece 15, it is preferable that, as shown in fig. 6, the medical device for hemostasis of the present invention further includes a second elastic piece 16, and the second elastic piece 16 may be a spring, a flexible rubber or the like. The second elastic member 16 is used to provide a force for the thrust member 15 to extend into the sheet inlet 201. When the pushing member 9 pushes the hemostatic sheet 100 to move away from the sheet inlet 201, the thrust member 15 can automatically extend into the sheet inlet 201 under the action of the second elastic member 16. When the pushing member 9 is automatically retracted by the second torsion spring 7, the pushing member 9 can push the thrust member 15 to return to the accommodating section 17. Here, it should be noted that: the elastic force of the second torsion spring 7 is greater than the elastic force of the second elastic member 16, so that the pushing member 9 can overcome the resistance of the second elastic member 16 to push the thrust member 15 back to the accommodating section 17 when returning.

As shown in fig. 7, the bottom end of the sheet outlet may be provided with a roller 18, and the axle of the roller 18 is rotatably mounted in the sliding bearing; the sliding bearing is arranged at the sheet outlet. The roller 18 and the sliding bearing are both metal members, such as copper members. The aforementioned heating means comprises heating wires connected to the outer surface of the slide bearing so that the heating means can heat the slide bearing via the heating wires, and the slide bearing heats the roller 18 via heat transfer. When in use, a user can press the back of the hemostatic tablet 100 through the roller 18, on one hand, the hemostatic tablet 100 can be heated, so as to further hasten the drug effect of the hemostatic tablet 100; on the other hand, the hemostatic bag can also play a role in hemostasis by compression.

The heating mechanism may include another heating wire 12, the another heating wire 12 may be embedded in the bottom wall of the sheet outlet channel 2, the another heating wire 12 heats the bottom wall of the sheet outlet channel 2, and the hemostatic sheet 100 slides along the sheet outlet channel 2 and contacts with the bottom wall of the sheet outlet channel 2, so as to be heated by the bottom wall of the sheet outlet channel 2.
