Drawings

Detailed Description
The objects, technical solutions and advantages of the present invention will become more apparent by the following detailed description of the present invention with reference to the accompanying drawings, in conjunction with the specific embodiments.
In view of this, embodiments of the present invention provide a distal radial artery compression hemostasis device that can simply and reliably achieve distal radial artery compression hemostasis.
According to an embodiment of the present invention, there is provided a distal radial artery compression hemostasis device including:
a body structure comprising an elongated grip assembly extending from a thumb end to a little finger end, and a palm plate disposed on an outer surface of the grip assembly and extending outwardly;
a first connecting band connected with the grip assembly at the thumb end;
a second connecting band connected to the grip assembly at the little finger end;
a pressing assembly disposed in the middle of the second connection belt and including an elastic pressing surface;
when hemostasis by compression, the holding rod subassembly is held by the user, the thumb end is located user's tiger's mouth department, the palm board laminating user's palm, first connecting band bypass user's thumb is connected to the palm board, just the second connecting band is connected to through the hemostasis by compression point of user's dorsum of hands the palm board, makes elasticity face of exerting pressure compresses tightly hemostasis by compression point.
Thus, when the puncture point of the snuff bottle area on the back of the hand of a patient needs to be subjected to compression hemostasis, the patient naturally grasps the long holding rod assembly, the thumb end of the holding rod assembly is positioned at the tiger mouth of the patient, and the little finger end of the holding rod assembly is positioned at the little finger side of the patient. The first attachment strap is secured from the thumb end to the palm panel around the user's thumb, which may hold the user's thumb in place while also limiting excessive thumb movement to adversely affect the back puncture site (e.g., dislocation of the hemostasis by compression or lack of pressure, even increased bleeding, etc.); the second connecting band is wound from the little finger end to the back of the hand and fixed to a palm plate in the palm of the user around the palm side after passing through the back hand puncture point (i.e., compression hemostasis point). In this case, the second connection strap is tightened with a proper force, and the elastic pressing surface of the pressing member provided in the middle of the second connection strap applies a proper pressure to the hemostasis by compression point, thereby achieving hemostasis by compression.
By such a design, upon compression hemostasis, the patient (user) naturally grasps the grip assembly with the tiger mouth at the grip assembly thumb end, the first connecting strap is secured to the palm panel in the user's palm after wrapping the thumb from the user's thumb back side toward the palm of the hand at the grip assembly thumb end, thereby holding the user's thumb in place, and the second connecting strap is wrapped toward the palm panel in the user's palm after extending past the dorsum puncture point (i.e., compression hemostasis point) along the user's dorsum on the grip assembly little finger side (past the side of the wrist) at the palm, thereby causing the grip assembly, the first connecting strap, and the second connecting strap to collectively form a triangle-like firm geometry around the user's hand past the dorsum puncture point (i.e., compression hemostasis point), allowing the compression assembly to be reliably positioned without being prone to deviate from the desired compression hemostasis point.
It should be noted that since the second strap may be secured to any suitable location on the (outer) volar plate attachment surface as desired, it may be adapted to the shape of the patient's palm and provide a suitable compression force for effective compression hemostasis as desired. That is, by securing the second strap in place on the palm plate, the "effective length" and tightness of the second strap can be conveniently adjusted, thereby providing a suitable effective hemostasis by compression.
Therefore, the distal radial artery compression hemostasis device provided by the embodiment of the invention can simply and reliably realize distal radial artery compression hemostasis.
Optionally, in one embodiment, the grip assembly is cylindrical or barrel-shaped. In this way, the user can more conveniently grasp the distal radial artery compression hemostasis device with the palm of the user to take the proper posture to wear, thereby facilitating compression hemostasis.
Optionally, in one embodiment, the pressing assembly includes a pressing plate, and the structure having the elastic pressing surface is disposed on one side surface of the pressing plate.
Optionally, in one embodiment, the second connection strap includes: an inner band portion connected to the little finger end of the grip assembly and an outer band portion connected to the palm plate, opposite ends of the compression plate being connected to the inner and outer band portions, respectively. Thus, when the compression hemostasis is applied, the compression plate and the inner belt part and the outer belt part at the two ends of the compression plate are stressed simultaneously, and discomfort of a patient caused by excessive concentration of stress at the compression hemostasis point can be prevented. In addition, the compression plate and the inner belt part and the outer belt part at the two ends of the compression plate cooperate to jointly compress the compression hemostasis point, and the structural design can enable the compression assembly (comprising the compression plate) to have a flat structure, so that the probability and risk that a patient collides with foreign objects/clothes in the compression hemostasis process are reduced.
Preferably, in any of the embodiments,
the palm plate is provided with an inner face (or called a smooth surface) matched with the shape of the palm of a user and an outer face (or called a connecting surface) opposite to the inner face;
when hemostasis by compression, the inner face laminating user's palm of palm board, first connecting band with the second connecting band is connected to the outside of palm board.
The structure enables the inner face (or the smooth face) of the palm plate to be better fit with the palm of a patient, accords with the ergonomic design and realizes better wearing comfort.
Preferably, in any of the embodiments,
a magic tape structure is arranged on the outer surface of the palm plate;
at least one of the first connecting strap and the second connecting strap is connected to a magic tape structure on the outside of the palm plate.
Preferably, in any embodiment, the grip assembly has a lumen extending from the thumb end to the little finger end, the lumen including a pressure regulating structure therein, the pressure regulating structure comprising:
a first threaded member passing from the thumb end into the lumen;
a second threaded member threadably engaging the first threaded member and extending out of the lumen from the little finger end;
a pressure regulating knob fixed to an outer end of the first screw opposite to the second screw;
when the pressure regulating knob rotates to enable the first threaded piece to rotate so as to drive the second threaded piece to extend or shorten relative to the first threaded piece at the little finger end, the second connecting band connected to the second threaded piece at the little finger end is loosened or tightened, and therefore the pressure applied to the compression hemostasis point by the elastic pressure applying surface is reduced or increased.
Thus, when the compression hemostasis pressure needs to be regulated, the pressure regulating knob can be operated at the thumb end of the holding rod assembly, the pressure regulating knob fixed with the first threaded piece rotates to enable the first threaded piece to synchronously rotate, so that the second threaded piece meshed with the first threaded piece correspondingly rotates and correspondingly stretches at the little finger end, namely, the linear displacement of the second threaded piece along the longitudinal direction of the holding rod assembly is realized through the rotary motion of the first threaded piece, the second connecting belt connected with the second threaded piece at the little finger end correspondingly loosens or tightens, and the pressure applied to the compression hemostasis point by the elastic pressing surface on the pressing assembly arranged in the middle of the second connecting belt is reduced or increased, thereby realizing the regulation of the compression hemostasis pressure.
It should be emphasized here that the operation of adjusting the compression hemostasis pressure is performed by the pressure adjusting knob at a distal position far from the compression hemostasis point, which is significantly different from some prior art methods of directly adjusting the pressure near the compression hemostasis point, so that the risk caused by accidental touching of the compression plate or the patient can be effectively avoided or reduced.
In addition, through the rotary motion of pressure regulating knob through first screw, realize the linear displacement of second screw in order to adjust the second connecting band elasticity degree with corresponding, can finely adjust to hemostasis by compression dynamics.
Preferably, in any embodiment, the first threaded member comprises a screw; the second threaded member includes a threaded sleeve that engages the threaded rod.
Optionally, in another embodiment, the first threaded member comprises a threaded sleeve and the second threaded member comprises a screw.
Alternatively, in one embodiment, the outer end of the second threaded member (e.g., threaded sleeve) may extend out of the lumen of the grip assembly (e.g., which may correspond to the little finger end of the grip assembly). In this way, the second connecting strap can be easily removed from the second screw member when maintenance or replacement of the second connecting strap is required.
Optionally, in one embodiment, the pressure adjustment knob is removably secured to an outer end (which may correspond to a thumb end of the grip assembly) of a first threaded member (e.g., a screw). Thus, when the pressure adjustment structure within the grip assembly requires adjustment, maintenance or component replacement, other components (e.g., the first and second threaded members) can be conveniently withdrawn from the little finger end after the pressure adjustment knob is removed from the thumb end.
Optionally, in one embodiment, the pressure regulating knob is removably secured to the outer end of the first threaded member (e.g., screw).
Alternatively, in one embodiment, the pressure regulating knob may be integrated with the first screw. This can simplify the component structure.
Alternatively, in one embodiment, the pressure regulating structure may include a locking structure that is in a locked state to inhibit rotation of the first threaded member when the pressure regulating knob is in the first state, and in an unlocked state to permit rotation of the first threaded member when the pressure regulating knob is in the second state. In this way, the pressure regulating function may be enabled or disabled using different states of the pressure regulating knob, thereby allowing or disabling the first screw to rotate for pressure regulating operation.
Optionally, in one embodiment, the pressure regulating knob is in a first state of the pressure regulating knob after being pulled out from the first screw member, and is in a second state of the pressure regulating knob after being inserted into the first screw member. Thus, only after the pressure regulating knob is inserted into the first screw member (in the second state), the pressure regulating knob is allowed to rotate to regulate the compression hemostasis pressure, namely, the pressure regulating knob plays a role equivalent to a key, and after the key is pulled out, the locking state is maintained, and the pressure regulating operation is forbidden so as to avoid the influence of abnormal pressure regulating or misoperation of a user on the compression hemostasis effect.
Alternatively, in one embodiment, the pressure regulating structure may include a manual locking structure that inhibits rotation of the first threaded member when placed in a locked state; when the manual locking feature is placed in the unlocked state, the first threaded member is allowed to rotate. Thus, by manually setting the state of the locking structure (e.g., lock/unlock gear), the pressure regulating function can be disabled or enabled as needed, thereby disabling or allowing the first screw to be rotated for pressure regulating operation.
Optionally, in one embodiment, at least a portion of the pressure adjustment knob is located outside of the lumen of the grip assembly. Thus, the hemostasis by compression pressure can be conveniently adjusted by operating the pressure adjusting knob.
Optionally, in one embodiment, the pressure adjustment knob has an outer diameter that is greater than an inner diameter of the lumen of the grip assembly. In this way, the pressure regulating knob is not inserted into the lumen of the grip assembly, thereby ensuring that the pressure regulating knob remains outside the lumen at the thumb end when rotated, while the first threaded member rotating with the pressure regulating knob only rotates and does not move toward the little finger end, thereby ensuring that proper linear displacement of the second threaded member is achieved by rotational movement of the first threaded member as desired.
Optionally, in one embodiment, the lumen of the grip assembly flares out in a flare shape at a portion of the thumb end. Thus, when the user grasps the palm plate, the horn mouth structure plays a role in reversing the action to limit the movement of the hemostat, and on the other hand, the pressure regulating knob fixed to the first screw member at the thumb end can be positioned in the horn mouth part to be protected from damage caused by accidental collision.
Optionally, in one embodiment, a stop collar is provided that is secured within the lumen of the grip assembly and that is sleeved over the first threaded member (e.g., threaded rod) inboard of the pressure adjustment knob (i.e., between the pressure adjustment knob and the second threaded member).
Optionally, in one embodiment, the inner wall of the lumen of the grip assembly has a lumen circumferential step toward the little finger end, and the outer wall of the second screw has a circumferential step toward the thumb end corresponding to the lumen circumferential step.
Optionally, in one embodiment, the inner wall of the lumen of the grip assembly has a lumen circumferential step toward the thumb end, and the outer wall of the second threaded member has a circumferential step toward the little finger end corresponding to the lumen circumferential step. In this way, the second screw member can be prevented from being excessively moved toward the little finger end (for example, at the time of the pressure adjusting operation) to cause it to be disengaged from the first screw member.
Optionally, in one embodiment, the inner wall of the lumen of the grip assembly has a planar portion parallel to the outer wall of the second threaded member to ensure proper linear displacement of the second threaded member by rotational movement of the first threaded member as desired.
Optionally, in one embodiment, the middle portion of the first connecting strip has a finger cuff. In this way, the user's thumb can nest in the finger cuff, facilitating the thumb being in place in the proper position to avoid excessive activity.
Optionally, in any embodiment, the connection surface of the palm plate may include a velcro structure; the free end of the first connecting belt comprises a magic tape structure; the free end of the second connecting band comprises a magic tape structure. Like this, through the magic subsides structure, the free end of first connecting band and second connecting band can be through dismantling the mode with suitable effective length (and tensioning dynamics) conveniently be fixed to the junction surface of palm board to realize the reliable comfortable fixed of distal end radial artery hemostasis by compression device and user's hand.
Preferably, in any embodiment, at least a portion of the palm plate has a plurality of ventilation holes. In this way, discomfort or skin conditions resulting from accumulation of sweat from prolonged wearing of the distal radial artery compression hemostatic device may be avoided or reduced.
Optionally, in one embodiment, a portion of the palm plate to which the grip assembly is attached has a plurality of ventilation holes. In this way, the fastening strap (first fastening strap and/or second fastening strap) is not hindered from being fastened to the palm plate fastening face provided with the velcro structure.
Optionally, in one embodiment, the hook and loop structure on the connection face has slits or holes aligned with the ventilation holes. Therefore, the magic tape structure can not obstruct the ventilation of the sweat of the hand of the user through the ventilation holes.
Preferably, in any embodiment, the pressing assembly comprises: an elastic hemostatic sponge, a silicone elastomer, or an inflatable bladder having the elastic pressing surface.
Optionally, in one embodiment, the first connecting band is an elastic band; the second connecting band is an elastic band. In this way, the connecting band with certain elasticity can be better adapted to the hand shape of the user, thereby providing better comfort for the user.
